Generac Generator Dropped a Valve - Will It Run and Make Power Again?

Рет қаралды 73,481

Ай бұрын

This Generac GP6500 Generator was given away for free. According to the owner, she was running it when it abruptly shut down and locked up. A friend took it apart and discovered a valve dropped out of the head and fell into the cylinder punching a hole in the piston and destroying the head. This machine was given away for parts. Can it be rebuilt? Or should I just swap out the engine? Things were going well with the repair until the load test.

I can't believe how excited I am seeing that James Condon just put up a new video. Love it! Thanks. James, I am 82 years old and am going through a difficult time in my life. Your videos have helped me bridge this time and distract me from negative thoughts. I have watched over 100 and have only made a couple of comments because so many other clearly capable viewers have said so many good and useful things. Ironically, too, I live in Germany where we virtually never have loss of electricity or blackouts due to our modern and advanced infrastructure (all cables underground). I don't know anyone with a generator aside from a few folks with RVs. Nonetheless, I watch your videos, as I am sure many others due, as a source of peace and calm. Thank you kindly for all of the efforts you make to share your expertise and experience in this therapeutic manner.

Protip James: Anytime you get a bad coil like that and have to change it, make it a default to also replace the plug. A bad plug can destroy a coil - this advice is also valid for cars especially most modern ones with separate coils for each cylinder. Change out a bad coil, replace the plug at the same time. Can't hurt and saves revisiting a bad coil again which I have seen happen due to a bad plug with really low resistance due to being faulty. Cheers 🙂

James, I hate to argue with you, but...the plastic 'screw' on the pilot jet actually slows the engine as it is screwed in. I had a Duromax that a fellow had screwed it all the way in and it only ran around 2000 rpm. The generator actually had an electrical problem with the carbon monoxide sensor that caused it to run for 15 seconds and die (I'm not sure why he adjusted the screw!) On another note: I had a Generac (GP5500) that came in with this EXACT issue (dropped valve, ruined piston.) The 6 bolt valve-cover heads are a MENACE. I believe the valve springs are too strong and cause excessive wear on the valves and seats. When the standard clone heads wear, the pressure-relief system begins to fail, and then it gets attention (or the user eventually ruins the rewind-starter.) The 6 bolt heads fail!

James - you found those valves at almost zero clearance! I was recently working on a John Deere 135 Automatic lawn tractor with 330 hours on the meter. Among other issues it had a slow/difficult time turning over to start. When I had the valve covers off to replace gaskets (bolts under-torqued causing leaking onto exhaust and resultant smoking) I checked the valve clearances. I found the Rights at .019 and the Lefts at .017 & .025 (instead of the spec .004-.006 for both)! I guess you just never know what you're going to find! In the end the FaceBook group experts suggested that it was bolt stretch over time, although I'm not fully convinced that's the correct reason. Pretty sure, though, that nobody had done the 200 hour check. Owner drove home with a smile on his face after the tractor started immediately. :)

I'm watching the entire video as I post this. Got a chuckle at the beginning when you said it should be an easy one, but the video is an hour long so assume I'm in for a treat this rainy Thursday morning. Interesting cost reduction to save a few pennies on the neutral connection making it very difficult to use this genie as a home backup generator for the reason you mentioned. Bonding and grounding are difficult concepts for many folks to wrap their head around so it is disappointing when OEMs make it even more difficult..

@r8118830 Ай бұрын

It is possible to change the bonded arrangement on this. Disconnect the red black and white wires. Remove the connection block and replace it with one with spaces for three posts. The black and red then go on their individual posts. The two white wires then remain connected together and are connected to the third post. The ground link is then removed. Why did they design it like this? I reckon to save pennies on using a two post block rather than a three post block,

Hello James, Another excellent autopsy of the blown up engine. When you got the other engine running I was really surprised. The purpose of the solenoid on the carb, on every engine I have ever worked on, is to stop fuel without power. ie the key turned off. Usually called an anti-diesel solenoid, it prevents run on and without power it blocks the main jet from receiving fuel. That the engine ran was shocking and apparently I don't know as much as I thought. What kind of solenoid is used on that carb, and what is its function? Thanks for sharing your time and knowledge.

@jcondon1 Ай бұрын

Same function as the carbs you work on. A lot of generator have the solenoid and are pull start only or electric start with a pull start option. The solenoid is normally open so you can pull start even with a dead battery (or no battery). When you click the ignition switch to off, generator power is sent to the solenoid through a rectifier to close the solenoid. It remains closed as the engine spins down and the generator stops making power. At that point it opens and stays that way until the ignition switch is turned off again with the engine running at speed. Generators without the pull start option (like the Generac XG10000e) work like a tractor as the carbs you normally work on.

@melkiorwiseman5234 Ай бұрын

I'm always happy to see a new James Condon small engine repair video, but I'm happier than usual this time because the engines in this video all use exactly the same type of carburettor as the generator which I'm trying to fix. It's marked as a "Ruixing 127 Engine" carburettor. Even the air filter looks practically identical. So, where I'm up to is that I got the engine running, but it still has problems. Firstly, it seems reluctant to start even on choke. Secondly, once it's started, if I immediately open up the choke, it starts to surge. If I let it run for several seconds before opening the choke, it doesn't seem to surge. But when I put it under a 1000W load, it started surging again even though it's rated for a continuous 1500W output. Where do I go to from here? The new carburettor came with a replacement spark plug (and a power switch which is identical to the ones on the engines in this video, but the generator uses a completely different design of switch), so what I'm thinking is that I'll just try changing the spark plug next and see if that makes any difference. The only other thing I can think of off-hand is that maybe I somehow made a mistake during the installation of the carburettor and I need to take it off again and check everything I did to make sure I did it right. The generator hasn't been run often enough or for long enough for wear in the valve seat to be a problem. So, am I on the right track, or is there something else which I should check? I'm reluctant to attempt to drill out any of the jets since that's a non-reversible change which may turn out to be the wrong thing to do. Unfortunately, the jets in the old carburettor are so badly stuck that they can't be removed, at least unless I can find something to dissolve the gunk which won't damage anything else.

@JohnSmith-pl2bk Ай бұрын

Surging = lean. Open up the idle jet with a fine drill one size larger as shown by James many times in his videos...

@melkiorwiseman5234 Ай бұрын

@@JohnSmith-pl2bk That might be what I need to do, but I first need to get the appropriate drills since even my smallest seems to be too large. And I'm not sure that it's the idle jet which needs to be made larger. I'd think that it's the main jet which would need to be drilled out. The engine will run on choke, but I need to let it run for around a minute before I can take it off choke, otherwise the engine dies around 2-3 seconds after taking it off choke.

It's like watching a ballet, or listing to Gustav Mahler's Symphony No. 5. It's magic!!

It's a long shot, but perhaps your tablet for showing the sine wave has built-in protection for surges and just needs to be reset. Those pinhole reset switches have saved me a time or two from throwing away something that I thought was broken but just needed to be reset.

You touched on the bonded ground in a previous video but really didn’t explain it as clearly as this time, thanks.

Hello James, I love your videos! Would it be possible, to show us around your workshop or show us the way you buy and sell your generators? I bet many young people could get inspired by this to start their own side hustle and learn something useful.

I recently bought a Generac power boss 4500 with a Honda engine. The p.o. said it quit running. It started right up and after about 2 or 3 minutes it acted exactly like this one did. A new plug fixed it as well. I have a Generac just like the one in this video. If the power boss would have been bigger I would have kept it.

Great video! Interesting how the engine grenades. Warranty should be on how many hours is run not how long you've had it, but then its another bunch of problems!

I often overlook the plug.

Hard to believe a bad plug caused the engine to stumble and carry on like it did especially when the plug end looked good. Very few times have I encountered a bad plug that looked good but I have in multi cylinder engines on cars.
