CAT D4H WON'T MOVE

Hi, I recently purchased an 89 cat d4h and am new to heavy equipment besides farm tractors. The guy that I bought it from said that the transmission had been rebuild about 3 yrs ago/less than 100hrs ago. S/N 8PB03682. He wasn't a believer in maintenance and it sat for about a year, so i changed oil and all filters on the machine and pb blasted all linkages. I had worked it 1 day, and the next day I was cutting in a driveway when i heard a pop, not real loud, just sounded like it popped...

Bobcat Skidsteer 953 Bucket Won't Lower

We bought a used Bobcat Skidsteer 953 that was leaking hydraulic fluid and the tilt wasn't holding. Took to a mechanic, who said the tilt valve was bad. Replaced the tilt valve, and the leak stopped but the tilt still didn't work. Rebuilt the hydraulic cylinders and everything worked on the drive around. Went to pick it up the next day and the bucket went up but would not lower, and there it sits.

Any ideas?

Thanks in advance.

Engine speed/governor handle tension set D4H

Ok more questions guys. How can i tighten up the engine speed/governor handle tension? it seems loose and will not stay put. Its like you have three speeds... idle, a little higher idle then all the way back for wot? No tension on it to keep it like half way....or is it designed like that?? Decelerator peddle works to slow RPS down...but you have to push quite a bit. The handle just seems to have alot of slop in it. Yes its tight on the shaft.

I'd love to be able to climb on &...

Rolling cutter for excavator - 1/2 thick steel

Have 100 ft. long sheets of 1/4 to 3/8 possibly up to 1/2 inch thick galvanized steel material to cut. Is there some sort of rolling sheer with cutter wheels or nibler that is made to put on a 30,000 to 70,000 lbs machine that could cut this into 40 ft. lengths for semi trailer to haul?

Auger attachment for 68,000 lb. excavator - 2 ft. hole by 20 deep

Need to dig some 2 ft. wide by 20 ft. deep piling holes. Would like to use my 290G Deere. Who makes augers to clip on the excavator. Or do I have to use a drill when going that deep? Guessing I have to take the arm off to run this attachment and lift the bit out when full of dirt every 3-5 deep deep? Digga is the only one I'm finding. Like to rent it for 2-3 days kinda deal.

How to flush engine that has milked the oil (headgasket) Cat 262B

Hi everyone just working on a 262B that has a blown head gasket. Any thoughts on restoring the engine oil back to normal other than just flushing with fresh oil. Eng has about 7000hrs and I'm having the head checked/ rebuilt. Crankcase is a mess of goop. Had thought to do an oil sample to confirm bearings aren't on a road to rapid failure after doing a couple flushes at least.

Thanks!
