My 003 is down

[Harleyd315]

I had an 003 running for about 14 hours when it just quit. The engine cranks, but almost sounds like no compression, no smoke out the ex pipes either. Pulled the valve covers spun the motor, valves on the fist 2 cylinders just barely move, 3 + 4 dont move at all. Intake pushrod on #1 cylinder bent. Any ideas would be appreciated.

 

[Speddmon]

The bent pushrod doesn't sound good. Since you were turning it by hand, did it feel like it was building any compression? If so, try to adjust the valves and give it a go.

 

[Munchies]

Ugh.... Does not sound good. Wondering about the cam health...... If you start to run out of ideas, pull the IP, and use a mirror to inspect the cam lobes.

Broken camshaft. Contact Storeman for a replacement.

The only time I bent push rods when engine was running was when I tried to burn though some very old fuel in a utility tractor. The varnish gummed up the valve guides. I got away with freeing up valve stems and replacing push rods. Were you using good diesel? Any chance it was over heating? Good luck.

 

[Keith_J]

The engine is interference, if the cam stops moving but the crank moves, there is a good chance a piston will hit an open valve. This bends pushrods.

Chris,
I have push rods, valves, heads and complete engines. Have not taken any down to the camshaft. Have scrapped the blocks at that point. Will help however I can. 804-725-4055

If the cam broke, and it is an interference engine, I would consider re powering the genset. Who knows what else is wrong. There are a bunch of MEP-003 engines around, including at least 2 sellers with new or rebuilt in SS classified. Realize this doesn't help if you power is down.

 

[storeman]

I agree with dependable.

Thanks for the help guys!!!!! Sorry I couldn't respond sooner. I kinda think maybe the cam is broken, no time to check it now. I have been busy moving 005"s around for the FD in our town. First the people shelter, then over to the animal shelter and now to a gas station that the PD has comandeared to fill up police and emergency vehicles. We are screwed power company says 5 to 7 days to get the grid back up. Refineries won't deliver any fuel oil and the whole town is on back up generators for water and sewer, using 90 gals per hour. I have my 005 keeping my house and shop working. And to top it all off I have 2 003 engines sitting in Mechanicsburg,PA waiting for me to pick up. I am truelly blessed though, I'm still breathing and looking at the green side of the grass!!!!!!!!!!! Thanks again and be safe out there!! Will keep you posted!!!

Sounds like you have the right attitude. I'm still waiting on word from my cousin and aunt in New Egypt, just north of JB McGuire-Dix. Last word was the lake level was rising (Oakford).

Phone rings through but no answer.

 

[storeman]

Hang in there Cris. At least you have the engine swap option handled. Be safe.

All done. New engine runs great. That gear reduction starter really spins fast, easier starts. Thanks for all the help guys!!!!!! P.S. When I get time I will pull the old engine apart and find out what let loose.

 

[storeman]

Way to go Chris!

If you are not repairing it I would be interested in buying it

Thanks Walt 401-255-2030

Finally got around to pulling the broken engine apart. It appears as if the oil pump shaft let loose and the loose gear broke the crank gear. The unit ran fine for about 14 hours during the storm and the just quit. Is this common or just an isolated incident?

 

[Isaac-1]

I am not sure how common it is, but I think someone else on here had one do the same thing a few months ago.

NJ_Toolnut had a similiar situation but he found a loose nut inside the front cover which got caught up in the gears, I didn't find anything inside of mine.
