Yeah it's because of the rings are collapsed.

My thoughts exactly as soon as I saw that , good catch

Noticed that wider carbon build up on #2, and wonder what that was all about myself. I agree with your diagnostics.

very sharp sight!

The bores did look decent so all that remains with that blowby is the rings. If the block and head looks good it could be possible to revive. Just fix up all those half-assed linkage and wiring jobs and it should be much more reliable.

You mean a musty

Wasn't it always?

Been watching Mustie every Sunday for years. My absolutely favorite

It’s been my Sunday morning routine for years now. Sunday morning coffee (or tea) and Mustie1! Glad to see what’s next for the bobcat.

And a coffee

Yes…..Cheap and dirty, no stinking clean-up……

Hope Darren reads your 'Top Tip' comment. 🤞🏼

@@David-yo5ws Y tube bans me so probably not.😖

@dubes5594 Absolutely yeah anything to do with an oil pump in a bobcat is gonna be super important, & great idea, a cheap fix, & a unique opportunity to fix a known problem. Well done! 👏👏👏👍

He'll probably make one of those pins using a lathe, or maybe several, so he has spares. He thinks similar to how I think.

Valve leakage

I was hoping for that, even if he choose to use a different engine.

He might even have freed the rings in place by pouring detergent, like Sea Foam, in the glow plug holes and soaking for a week. then it would probably just start right up with no engine removal or disassembly; and if not, try Restore ring sealant as well. All without even a head gasket.

@@alan6832 it depends on why the rings where stuck. If it's because of overheating it would not work.

That's what I'd do, Hone the bores (they don't appear to be wet liners which I think he was expecting) clean the pistons up and change the rings out for new ones then reassemble with a new head gasket

@@osbberjen They looked caked with carbon to me. Why would it not work on overheated rings? do they weld themselves to the lands or something?

I think he's a Salty Cracker fan. I see "4:30 Avocado Time" on his locker. That is when Salty does his live streams Wednesday, Friday and Sunday.

I got in alot of trouble as a kid taking things apart...door knobs, alarm clocks ect. My dad finally locked up all the tools and yelled " You cant just go around breaking things !!!"

I try to avoid disassembly, and in this case I thin he could have freed the rings just by pouring detergent, like Sea Foam, into the cylinders and letting them soak for a week, with no engine removal or disassembly. Then maybe Restore ring sealer if still necessary. Unfortunately, I doubt he could roll start a hydraulic drive because if it was a gear box, I would say haul it up a mountain, roll it down and dump the clutch at almost the redline. I have certainly started old diesel Rabbits that way, and it might be a permanent solution after soaking the rings so you don't need that mountain every morning.

Does seem like a nice little engine

Yeah with the amount of soot in the engine compartment, it looks like it was breathing it's own exhaust for some time. Would kind of be like us trying to survive by breathing our own farts. You probably wouldn't live long either!

100% correct- good catch

No need to yell, the center cylinder had the worst compression and we knew that from part 1, Ace.

I would do this first, next to no cost

Second this. We put new pistons and rings on a 3 cylinder yanmar. The bores were very worn. Still runs great 20 years later go figure

Ever heard of knurling the pistons and fitting in oversize rings? Hone it out, Leave a 3-5 thousandths ring gap and go.

If the beetle engine can stay cool and have enough HP and torque then it would be an option. The other question is how much the fuel consumption is on the beetle engine compared with a Kobota diesel engine.

@@Frank-Thoresen yeah but, seriously, there's a big back door to pull ventilation through - add grilles if needed. In my own head, width might be the biggest restriction - those engines are wide. Still, Beetle BobCat would be super cool though? Fuel consumption wouldn't come into it - he'd only be running it for a few hours a year at the rate Mustie1 runs his rustorations.

It would have to be an engine out of a Bus or a Type III because Type I engines do not have the bosses for the mounts cast in.

@@josephheston9238 cool. I only know what Mustie1 has taught me about VW engines, but these are all engineering problems that can be easily solved.

@@Frank-Thoresen The VW would use 4-5 times the fuel that the Kubota would.

Probably could put a D1005 Kubota engine in it, they're around 26HP, the D662 that he pulled out of that Bobcat is only 19HP. So even a D922 which is 23HP would be a slight upgrade.

I was thinking same exact thing!!

thats not how any of that works, and even if it would work itd required alot of custom machined adapters, and an excessive amount of work, wouldnt make any sense makes far more sense to dive into the generator unit and try to repair it, either itll be a working unit he can sell, or if he runs into a generator or motor issue thatll answer his question on using that engine

Rumor has it Mrs Mustie requested the gloves. I guess his hands were getting a little rough on her a, a, merchandise?

​@@kevinfoster1213I know this is way off topic but I had a friend that had hands that were terribly rough an huge cracks like I've never seen and that was the one thing that always come to mind there is no way any woman could enjoy that sorry @mustie1 for being off-topic in your comments

Yes the engine is worth restoring but too weak for running this Bobcat. Mustie need an engine with around 30 HP.

I was gonna say the same thing. All in all, nothing looked really bad. Definitely would want to measure bore wear to ensure a mostly straight cylinders, but I'm be tempted to do the same thing. Hone the bores, new rings, lap the valves, and slap it together. Idk maybe some valve guides/seals.

Yeah rings are overrated.

A turbocharged 772 would be fanatic in that machine!

@@Frank-Thoresen I would say Mustie is not going to be pushing this machine anywhere near its limits. This thing is not worth a lot of money even if it were running with a bigger engine. All of the hydraulics probably need work too. An under-powered, but running machine is better than no machine.

Best way to start a Sunday. Musti1 and a cup of coffee.

Install a vw diesel

6:00 a.m. here in the midwest.. Coffee time!

South of Boston 48 degrees! no boating today.

@robotcantina8957 is the channel - good call, I agree with you, a two minute conversation between these two would clear up a lot of questions. I certainly have enjoyed the saturn project

The kubota engine he put in is only about 18 hp, remember in the latest video where he is installing the predator 2 cylinder engine that is supposedly 22hp, Jimbo said the predator has more horsepower than the kubota and Mustie (Darren) said the original Ford engine was about 35-40 horsepower and the kubota D622E is under powered, so the D722 in the Saturn will also be underpowered for the bobcat. Why waste your time with some underpowered POS kubota? Put a proper 45-50 hp gasoline or diesel engine in it and then have a very useful piece of machinery. A small car engine would work.

​@@kd5inm I mean, yeah a D622 isn't terribly powerful, but it's not a bad engine for what it is. Kubota engines are very sturdy for what they are, and something appropriately sized for this skid steer would be better.

@@tsp159 I used to work for a kubota tractor dealer as a mechanic. After working on those tractors and engines I am not impressed with the durability or build quality of their equipment. Kubota and Yanmar are both from Osaka Japan but I believe Yanmar is much better made in both engines and tractors and power equipment. Yanmar engines have sleeved cylinders and a 10 year warranty on their powertrain in their tractors. I have an older yanmar tractor that is 44 years old and its still running strong.

@@kd5inm he has a 20KW kubota engine there but wasnt sure how to make the governor work.. he could get some info in regards to that if the head on the genset unit is fried

True.. Quick recondition would work.. Doubtful if this Bob Cat will ever see continuous 80 HR, 52week, 365 day use. VW might be a bit high maintainence for this APP.

Jacques Deschênes..... Not enough power.

He was measuring it in the last video . Quite doesnt fit cuz he dumbed the idea.

Id back that!😅

easy enough to plumb a turbo into the exhaust and intake, but how do you make the injection pump feed the appropriate amount of fuel for the PSI boost it currently has, im only familiar with Diaphragm setups that reference boost pressure like on the bosch ppump series, everything else uses electronics, youd have to either drastically underfeed or overfeed it fuel leading to a lack of power, or excessive smoking

@@AndrewBrowner I'm not sure, maybe try to source a larger injectors or some kind of propane injection?

@@augustm.moschera8646 No, I don't know your extent of knowledge on the topic of mechanical injection pumps, but the issue is that on a non turbo unit like this the fueling is linear to the rpm because the engine only pulls in a certain amount of air at any given rpm, a turbo unit on the other hand can vary widely in how much air enters the engine due to the turbo force feeding it, so a boost reference diaphragm is needed on the injection pump to adjust the fueling so when the boost comes on it doesn't lean out on the low rpms or just in general.

@@ethancoy9237 Ok, now i see what your saying.

I saw one on marketplace a while back.

@@the-vapist2242 I'll bet that thought has crossed his mind!

It's a lot of work if the engine even in perfect working order is not powerful enough. I would just find the right powered engine.

@@messenger8279 Show me the difference in torque ratings of the original gas engine and the replacement diesel engine and I'll agree with your point. There's no telling if the rest of the machine is any good to start throwing good money after bad. What makes you think that a different engine would be of a better quality than what's already being used? Mustie has an engine with stuck compression rings. Unstick them, check the valve seat, and throw it back together. At the minimum, you have an slightly underpowered machine that has a good engine for almost no additional cost. At that time you can upgrade the engine if needed.

The diesel's torque is probably even higher than the original gasoline engine, so I doubt that the diesel died because of regular stalling. Still, it is possible problem with the RPMs of the diesel. If everything in the Bobcat is made for a gasoline engine, probably for reaching a reasonable speed of operation, the diesel engine was working on max rpm constantly.

@@stans5270 I found this not sure if it helps but the Kubota is only 16 HP the original is 32 hp. The relationship of HP and torque is as follows. Is torque directly related to horsepower? Without going into too much technical detail, here's how you can calculate horsepower with a simple equation: Horsepower = Torque x RPM / 5,252 (where 5,252 is the conversion between lb-ft and horsepower). This means the two are closely linked so, often, higher horsepower means higher torque.28 June 2021

@@messenger8279 Where did you get those figures from? Your torque formula isn't valid for diesels. And it's not even valid for different gas engines. Show me the model number of this engine and where on the video it is shown.

Two instresting channels for sure.

WOOHOO !!! That would be a "two-fer" !!! 😊

I think it is just the carburetor that is designed for constant speed in a generator.

Ye I would keep the Genset as is and try and get it running before cannibalising it. As for the bore on the Kubota the David Brown 885 tractors have the bore reamed straight in to the cast iron block with no separate sleeve. My 885 pinholed between the combustion chambers and water jacket so the fix was to bore the block and press fit sleeves in to the block. Engine runs a bit hotter than original because of this but was cheaper than a whole new engine. I would also try to get an engine of at least the original power output otherwise the Bobcat will be totally gutless.

What a load of rubbish those engines are all built the same the only difference is the governing they can be fixed speed or variable speed

@@quadrapoint You could have said that without sounding like a pompous jerk. If you had omitted the 'what a load of rubbish' part it would have been much better and maybe even got a 'like' as it would have been constructive rather than offensive. That aside, I based my thoughts on my own experience on finding configuration differences depending on intended application. So my comment may not be 'a load of rubbish', as you so arrogantly put it.

Coffee and smokes count? :)

@@Ajaxaxxess Yep

@@pcuser80 Good! Been my sunday a.m. for years :) Have a great rest of the day man!

@@Ajaxaxxess Thanks man :)

Я был рад видеть перчатки, когда он удалял масло.

Can't help thinking that both of those are still underpowered at 25hp. The original engine was 35hp for diesel or 32hp. The nearest Kubota engine would be the d1402 at 33hp. Edit: the governor system is the same type on all the Kubota engines so whatever throttle conversion works on the D662 should work on other models.

nice catch...

@@chrishartley1210 To avoid hydraulic stalling you need torque, not power, and he is already replacing gas with diesel, and the hydraulic system is worn, which reduces the needed torque still farther, and so what if an old machine is slow? So I think all he needs to do is unstick the rings and he can use the engine he has. He might have even done that in the machine by soaking the upright cylinders in a detergent like Sea Foam, where now he would at least need a gasket set. Then there are also ring sealants like Restore for very worn engines, though I still don't know how well they lubricate. Unfortunately, I am faced with similar problems on a Subaru boxer engine with vertical rings, which might be considerably harder to pour in detergent and soak, so then detergent might have to be added to gas and oil to unstick rings, with unknown effects on the lubricity of oil, like any oil additive. Still worthwhile though if the engine is otherwise junk or nearly junk, not worth an overhaul. They used to sell another ring sealant called "Yale Overhaul Pellets" but they stopped making them, though I hope they find a big supply of new old stock to supply more than collectors. I had real success with the stuff, though it was supposed to go in a hot engine, so he would have to get this one started to warm it up. No such problem with Restore I don't think. Project Farm got a diesel tractor to start with Restore that lacked the compression to start otherwise, just like this. Still, I think the main trick is to unstick rings without disassembly, but I hear detergents can do that.

@@chrishartley1210 Also, if previous owners wore out the little engine by using the machine until it wore out, then the type was certainly usable or it would not have been so used. All he needed to do was free up the rings with detergent.

@@alan6832 Certainly it is repairable but is it worthwhile? It may need new sleeves too. But the big question is why did it overheat. Was it simply because it was undersized?

IKR...shoehorn one of those VW engines in it...that would be awesome!

Duetz air cooled engines came in many bobcats, they are their own can of worms though.

heh, no kidding, a nice 1776 dual port with Webers and a Stinger exhaust hanging out the back and the cylinders poking out the sides!!
