This is just what is needed for partial rv backup. Operates the ac and stuff perfectly. kzfaq.infoUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y is quieter than my rv generator. Only suggestion is that it needs a fuel shutoff valve. So it is easier to store.

It's really disappointing that supposed professionals didn't even bother to carry out the most basic diagnostics to identify the problem with the engine, rather than just replace the entire unit! Your video was truly excellent, thank you for taking the time to record, edit and publish your work. I'm delighted to have found your channel and think that you inspire and encourage others to have the confidence to work on machines that they otherwise wouldn't!

Mike, you have the coolest tools for this business and more importantly, twice the knowledge anyone needs to get the job done. It looks like you were still at the old house, too. Thanks, bud...great video.

great job Mike , You fixed it . Glad there were no broken parts in the valve case , ENJOYED !! Wet soaks are a diesels best friend for a long life ..

Great diagnosis and repair. Nice little generator to boot. I hadn't thought about a diesel one for the fifth wheel but after seeing this it may be the way to go as I carry extra diesel for the truck when he head back into the woods. Thanks for sharing.

Great job. I love watching a pro. This was a great example of "one man's garbage is another man's treasure"'. Thank you for sharing.

As we say around here Mike,...you seem to have "made out like a bandit" with this one. Nice little gen-set. Very interesting video,..Thank you for this one.

Thank you for posting! This is the stuff I like to do and it’s nice to be able to see all the cool stuff everyone else works on.

Mike, this is the best video , by far and away, you ever put out! Tony better watch his back!!!,,

Nice easy fix Mike! I noticed you have a service pit in the floor of your new shop, that will come in handy! Thank you for the video!

Thanks very much for an extremely entertaining and informative video. I was impressed by your skill at diagnosing and repair. I love small generators, what a nice find!

Great video. I have one in my RV. Getting to see it opened up is a real treat. Mine is about 10 years old and only 100 hours on it.

Thank you again. I have had no knowledge of these small diesel engines and generators. I currently am off grid and using solar and gas generators for heavier loads and tools. I would like to have a slightly larger diesel with remote control and monitor. Your videos have been very helpful increasing my general knowledge. Especially the fact that they don't like running at lighter loads.

Just was driving on 295 north and saw your truck, recognized the channel on the banner u had on the truck! Figured I’d say hello!

I ran into this problem with small gensets a lot. Running these under low load conditions is bad. Love that old Milspec load bank.

These are sweet generators. I had a 7500 Onan quiet diesel in a RV I used to own. Giving up that generator was the most difficult part of selling it. That is a nice find & fix. Enjoy your channel.

Right place, right time to get that baby. Your load bank is an oldie. Saw selenium rectifiers on the bottom between the transformers. Those we're from back in my day.lol

Very nice job. Thanks for the video. I have a small engine shop (semi-retired) and had a very nice riding mower given to me that only had a leaky carburetor on it. I rebuilt the carb and use it a lot with no issues. Thanks for that video.

Really interesting video; nice to see the master at work. Sweet little Onan you were gifted- I would love to connect that up to my house for emergencies. Thanks for making this video.

really nice work on getting that little gen working, glad it was an easy fix!

I love companies that dispose of good equipment. I was awarded the Fred Sanford award at the aerospace company I worked for. I was the senior dumpster diver! Oh.....the treasures!

That’s a sweet little genny.i was thinking the same thing about that muffler maybe being too clogged up. Looking forward to part two!

I just bought my 1st motor home it is day 2015 Coachman prism 2150 and it has the same generator and it kept turning off every 10 minutes and I thought something was wrong with it, come to find out it was just low on oil. These generators appear to be really good. Thank you so much for the video.

First of all, ignore the comments about your camerawork. Its fine. Maybe get a mini tripod or a head mount for giggles. Loved your running commentary. Very informative. Just subscribed

I think this is the best video I’ve seen all year. You’re now a Jedi Master.

Great video! I thought everything was going to be ok when you picked up the rocker arm and pulled out the undamaged pushrod. I did not expect that much soot. I hope you banged the muffler with a rubber hammer and forced air through the muffler; while you had the muffler out. Good find for you. Handy to have around.

Cool repair job and everything, but seeing an old international coffee tin was the highlight for me. Havent seen one of those in 20 years!

Good video man here in Southwest Florida generators are a fact of life I just turned mine up just in time for the hurricane we got coming.

I repaired my diesel generator yesterday. Broke down this fall. Had sucked up some metal parts from the air filter. Was a 3" long shred in the intake valve. Had to sand it down and adjust it and it was golden, exept from the air filter which was relieved of its 14 year long journey. :D

thats a real nice machine, great score,

Nice generator. I guess this was an easy fix for a perfectly good diesel generator. I always appreciate when people throw out stuff for free or almost free that I can repair.

What an effective tune up! Great job !!!! Love me some Diesel!!!!

Nice unit - thanks for sharing this - looking forward to more videos in your new shop.

When I first started watching I thought this is just another shade tree mechanic video. I became apparent pretty quick that you know what you are doing (even before I seen your shop). Anyways, you made great and very informative video and gave some good advice about the wet stacking.By the way, I love the surplus military load bank.....brought back many fond memories. I just to test generators at 80% for about 2 hours when I worked on them.

Been subbed to you and roadking for years. I'm glad your vids seem to be getting more attention.

Hatz so loud... really nice old load bank love to find one. I set up a one mega watt one to test Nuke back up gensets . A Giant toaster. Excellent work thanks.

Great video. I was looking at buying this generator and trying to get all info before purchase. Very informative for future trouble shooting and doing increased preventative maintenance. Thanks, Great Job!

Loved the video. First video of yours that I've watched. Have to go look at the others. Loved the load center. Everyone should have one in their shop. :-) We had a homemade one when I was a kid with a Variac and a huge resistor to test voltage regulators. Brings back memories.

That was a great video Mike so interesting start to finish great job 👍🇦🇺

I've been to the plant in MPLS MN. Kind of fun seeing the units in production!

44:00 - That's what I'd call your carbon foot print! Great job!

Nice find. From experience these engine give lots of valve trouble especially on the exhaust side, they need to be checked every 250 hours max, likewise as you said the oil should be changed every 40-50 hours. Thanks for uploading.

Wet stacked. Been run underloaded all it's life. You really need to load them 75%> of their rating to prevent that. I think you've caught it in time though 🙏👍 I always run our works backup generator hard on tests!

Hoss, 369 hrs is damn near brand new on that little Jewel!! my little Carrier Comfort Pro has 17,000 plus on her and still goin strong on my big rig!

I just watched from start to finish. Subscribed!

Sweet generator. good job bringing it back to life.

I like that these videos are not over edited.

Good job and explanation. I have seen diesel generators smaller probably for about $1000 on ebay not sure if they would last long.

Nice loadbank ! I would've just had a round-up of various kitchen appliances (we are 230 volts, 50Hz here), water kettle, toaster, electric room heater etc and plugged in enough to bring it up to the required amount. (But I just found this channel) and it looks like you fix generators a lot, so worth it for you to have a dedicated load-bank.

Great videos I enjoy your descriptions and explanations of what's going on. You do need more lanterns on your shelf in the back of your garage though.

Always a great presentation. Yes, I also like remote oil filters (ie. V8 Vega) and oil coolers (ie. Drag Pack option on 428 SCJ's ). Thank you S E M!

I think the reason for the "pop" on the intake is simpler than the one you suggested. With the exhaust valve not opening, the exhaust stroke would effectively be another compression stroke so when the intake valve opens, the cylinder is under pressure again.

I used to rebuild kubota's and perkins/cat c2.2 engines. Using starting fluid was the cause of push rods mysteriously poping out of place. I'd bet someone used too much ether and then they thought they had destroyed the engine. Nice to see another abused diesel brought back to life.

If that little rig were mine, I would engineer a remote mount oil filter, and an external oil cooler. It would increase the oil capacity, and add a second form of heat rejection. It would probably double or triple its life expectancy also.

That is an awesome little unit! You made out pretty well with this one :)

Mike - Some questions and observations in no particular order. First off, an outstanding video full of nuggets of info and observations. I personally don't care if you go weeks between your video's if we can get this quality and in-depth of a video! Kudos! Looking forward to seeing your new shop and all the clever design goodies you come up to outfit it with. I'm hoping that you didn't run the engine with the air filter off. The exhaust soot/coke that was collecting at the rear of the generator could just as easily been pulled into the gen housing and into the motor air inlet to say nothing of coating all the components within the gen housing. If I were Mr. Onan/Cummins I would be on the phone right now to your service department and in particular the person responsible for declaring the genset a warranty replacement! Even at $150 dollars an hour shop fee it would have been well worth the time to trouble shoot to the problem. I'm betting here that the actual charge back fees to Corp for labor and parts is way way less than the fees charged customers! If nothing else this should have been an instant in-house refurb candidate and not a junker! I am even more amazed that Germany with their high wages could produce and market this gen set cheaper than say Japan or Taiwan. Would love to know the economics of this set. Regarding your load set. Since most of the gensets that you load test are basically just single phase you can use the other legs of the load set instead of just phase 1 to spread out the 'wear' on each of the load phases. Not familiar with this particular load set but it should have the capability to go from zero to whatever the indicated max load is you have chosen. So if you were on the 20Kw load setting you should still be able to vary the load from zero to 20Kw ...I think. Also if you are doing high current loading with your load set, the covers are just as important as they are for the gen set for proper cooling of the internal load parts. I'll mention this again. I have no problem kicking in some money to get parts and cover some of your labor for the Cat genset. I hope that some of your other YT followers would be will be willing to do so. If you can come up with a "wish list" we can not only buy the parts, we can also hunt them down if need be. This will have to be coordinated so you don't end up with 24 thousand cotter pins!

Have the same generator on my 2017 Winnebago View. The orange wire is the temp sensor. Looks like the sensor end is cut off as the metal tip goes into the air filter housing. They are notorious for shutting down in the hot weather. The red button inside the housing actually shuts off the fuel solenoid to stop the engine. My solenoid got stuck open and would not shut off. Replaced the solenoid and all good now. Great video for my next problem with this generator!

Thanks for this vid. What’s interesting is that this vid has value today as when it was made. These units are fairly common so when I’m shopping I’m armed with a little info. BEt this was a common design, build problem and not a show stopper.

Nice little score, just goes to show how important it is to specify the right generator for the job.

It just needed to be cleared (run). That is such an awesome unit. I used to hate diesel. I was tainted by old Mercedes cars that sucked. Rear bumpers covered in soot. I am watching a lot of videos that make me love diesel. They run forever. Thanks, SEM!

Great video! Shop is coming together. Thanks for posting this.

Nice little gen-pack. Defiantly needs running on full load like you said.

Awesome vid, awesome generator, awesome repair, awesome load bank !!

I had the same thing happen to an Onan V-twin on a Miller generator. The initial oil gummed up the valve guides because it hadn't been run in a long time. The valve hung up and the rocker popped off. Some brake cleaner down the valve guide loosened them up and cured the problem.

Really good video. I might have used caustic soda on the exhaust and wood dowel the tailpipe. Let it sit overnight. Nice genset

This guy thinks very precisely, it’s a pleasure to see. He is like me and my coworkers doing database or programming.

I’ve got this unit in my Winnebago View. Very expensive upgrade over the propane genset. Nice find!

Great stuff! I love getting machines like this, its the ultimate bargain! My guess is they took it in for a service and someone forgot to tighten the rocker adjustment properly and the exhaust backed off. Probably later diagnosed the intake kickback as burnt valves when it was actually "jake braking" out the intake since the exhaust system was no longer part of the plumbing! All the orange RTV in the exhaust pipe is the tell to me.....anytime I see RTV beyond a small bead or skim, its a sure sign of an amateur being involved....doubly so if its orange RTV since that stuff is rarely used by the OEM.

Good old 15/40! I was running a D8-H on a dam job when another crew decided to work saturday. I came in on monday and no 8. I hopped in the foreman's rig and we went hunting. It was hidden in a hollow, still RUNNING! It ran all weekend and had sutted the stack up to about a 1 inch hole. I pulled my coat over my head and yanked the throttle open. Soot rained down for a WHILE! When it slowed down I ran it over and filled it up with fuel and oil. It spit a piece of soot for a day or 2 but no after effects. Tough old lo speed Cat!

Good save, Mike! Cool little unit!

I have a little 6 hp BMW diesel in my sailboat circa 1979. Has a Hatz motor marinized by BMW. Still running after 40 years.

That is a great generator. Here in Scotland I fitted a UK spec Dometic TEC 30D to my RV (have never even started the original twin cylinder Kohler, with petrol being about £1.30 a litre, or about $6.40/gal) It is a Hatz diesel and the controller looks very similar. Mine started with zero hours, now it has 518 on the clock. Mine needed a new fuel pump to get it going, it later needed a new exhaust pipe and a new air filter as it sucked in it's own exhaust from the split in the pipe. Under partial load it only uses about hslf a litre per hour and on a rainy day it can dry the ground under the RV. Mine's in a basement compartment with a vent at the side and bottom, makes it very slightly quieter.

Enjoyed the VID. That's the kind of stuff I do for fun. I have several small gas generators I picked up like that. Funny no one even tried to fix them. Just tossed them and replaced them. I'll bet that thing will quiet down a lot when you put the intake cap back on it. Like running a car motor without an air cleaner cover. Had a Diesel Motorcyle with one of those single cylinder diesel motors in it. Got 120 MPG but could only get 55 MPH out of it because it was only a 10 HP engine. Stereet legal but rode like a kids mini bike with a CV transmission. Sold it to a guy in Iowa and he rides it to work everyday.......

brought a silent gen for 5k from a company for $200 and made 5k off of it after spending no money on it to fix it a wire came off the display panel 😁....fixed alot of those push rod problems too,stock valves, bugs in the intake and out for sitting to long etc....love the video

Nice score dude! I would really be interested in the load center rebuild when you do it.

That's a great gen-set Mike , you have a good one there

That's awesome! As many problems as they have come through, if it seems like it might be a major issue, it's cheaper for them to just replace the whole thing than spend time troubleshooting what could be an issue they won't repair. If it seems major it probably is so just proceed as if it is.

I enjoyed this video very much, it was very interesting to me and methodical. Nice work ! You've earned yourself a new subscriber! 👍

Have the same gen set built into my 2015 RV. Thanks for the education.

Sad that we all want smaller and smaller stuff but yet do not appreciate that it comes at a price..... I'm reminded of Cellular Phones..Initially....They were HUGE! But everyone wanted "the "smallest"...and even went in bars and bragged how "small theirs was..." (ouch) Then it all got daft...and the phones got bigger and bigger until most "cool" people are now walking around with phones at a size that would have been laughed at a few years back.... Crazy world? This Generator is the equivalent. Great video. Shows us all the reality of miniaturisation. In many situations: It doesn't work. If that unit had been but ....a foot wider.... it could have worked comfortably within its own specs..... Daft design. Inevitable result.

years ago I used to work on Army 60 Kw generator trailers, my unit had 3. we were an aviation direct support unit that as many people in a company as some battalions.

Ok now you did it. Got my brain turning and looking for a deal like you got. Easy fix. Looks like the adjuster just backed off and the push rod popped off. Leaving the exhaust valve closed made the combustion blow back through the intake just like a small block Chevy rounding off the exhaust cam lobe.

Perfect example of how easy we throw away things. This little generator has a Hatz mini diesel, with proper maintanance they will do many years of reliable service. At least you now have a nice little piece of good quality equipment, congrats!

I didnt know they made such small units like that! Cool!

Enjoyed this and most of your videos very much. Thanks for doing this.

I would love that for my sailboat.... Incredible find.

Yep same one we use on frac jobs in frac vans Have changed out alot of them over the years Very good equipment, oil change every week to ensure life was policy, royal puperal oil only

Good video Mike. Cheap Genny, easy fix.

You’re a pleasure to watch, thank you .

That is a sweet little generator , good score !

Thanks for the video. I just purchased a Genset MG 13/10 AA generator that only had 52 hours on it since it was purchased in 1990. It was a backup generator on a chicken farm and when I was running it to test it, I noticed the same white smoke. It has a Ruggerini RD 270 two cylinder diesel engine which is bullet proof and considering the low hours, I wasn't sure if the filter was blocked or the injectors were dirty and the fuel wasn't burning. Since it was a backup generator and was placed under load once warmed up, I don't think the issue is glazing. I will hook it up to some heaters and let it run as I suspect it's just soot buildup in the exhaust as the smoking looks identical to what you showed in your video.

I have earned so much from watching your method; very inspiring thank you.

Wish I could get my hands on one that would be great four my truck thank you the video

SCORE!!! Always feels good to get things like this up and running

Just don't understand why some units are made that just seem to have such small oil capacities. I don't have the development skills to figure out how much it should have, but damn, 1.1qt in the sump just doesn't give you a lot of 'mistake space'. I put an outboard one gallon tank on my gennie, 25kW Generac Diesel, and just let it 'overflow' back into the crankcase. Gives the engine the extra gallon in capacity while keeping the oil level at the same place. I also put in a sight glass in the piping to allow a 'running check' on the oil level. Another Great video, Michael in Colorado.

Wondering if the Muffler is coked up clogged with up too much back pressure?

Great video! I enjoy your content! 👍🏻👍🏻✌🏻

It was very interesting to watch, thank you!

Man cool video. I geeked out the whole time

I love finding using useful stuff on junk piles that only need a little research a basic tools to repair. Own many lawnmowers because of this.
