Hydraulic problems on a 1010

[rrwayside]

Back again.When does it become fun to own a dozer.Got two days work out of it,after weeks of working on it.Let a friend try it tonight,he only drove it for about 5 mins.Now I have nothing at blade.It will not raise,lower or tilt.It has a reverser which is still working,so I assume it is not the pump.Just looking for a starting place.Thanks in advance.Rich

If you have a later 1010 with the hyd pump disconnect, make sure it is not disengaged. Also check for air leaks in the suction line, oil level, simple things like that.

It is a 1961.Did check oil level.

I had a similar problem.
On mine it was a small leak where the return line from the pump rubbed on the frame of the tractor, I assume causing it to suck air. I finally noticed a fluid leak when shut down and then replaced the rigid pipe with flexible hose. I then cut the old one in pieces with a saws-all to get it out without removing all the belly pans. Worked fine after the fix. I did however have some clues that trouble was coming, it hesitated and jerked a bit, then pretty much quit completely. I also had the problem on a loader not a dozer..

You might have a similar problem???

ps, I saw that the pressure line had a lot of rubs on it also, so I split some black water pipe end to end and clamped it over to protect it from getting holes as well. I have used this easy repair more than once since.

Wish it was just a leak.Changed one hose,but as I figured it wouldn't be that easy.Found out the drive coupling was stripped.The splines on the pump are somewhat worn,rounded alittle on the one side.Should it also be replaced?Can you replace just the drive gear and are they available?
