starting
Anyone here ever tried to pull start a dump truck? I have one that I have to move this weekend that hasn't been started in over 3 years. I put three new batteries on it, cleaned all the connections, rebuilt the starter and still the same result...it turns over like the batteries are nearly dead. I even ran a pair of 00 gauge cables directly from the batteries to the starter...same results. I'm considering towing or pulling it to start it, but have never done this with a truck this big. Anyone here ever done it? If so, do you have any advice?
As stated, there is alot of info you are not providing us. gas/diesel/air brakes/year model/etc, kind of tranny
I would see if you can turn the engine over with a pull bar, or take the starter off and use a pry bar to turn the flywheel. It sounds like something is preventing the engine to turn, could be
1.stuck engine/seized rings
2.water on top of the piston (head gasket, cracked head/block, etc)
3.unburnt fuel on top of piston, locking it up (mostly a diesel problem)
4.is the tranny/clutch stuck in gear causing you to try to turn the rears when starting
I have pulled dump trucks to start, be sure to have a good driver in the dump truck, so he doesnt rear in the puller truck. I almost bought a dump truck a few months ago. It was a 88 Ford L9000 tandem, L10 Cummins diesel, 155,000 miles. It had been sitting about 3 years, tried to jump it and no luck, I ended up pulling it and did get it started, but if you cut it off it wouldnt turn over and Im loosing water. I didnt buy the truck, but it was a cracked head, letting water get on top off the piston. If its a diesel, air brakes, you have to charge the air system and make sure you have the fuel shutoff valve it the correct position (not all engines have this) mostly Cummins.
Keep us posted, good luck
