Just fired up my two year old Huskee 22 ton and split a piece of wood and the cilynder won't retract. Any ideas what the problem is? Everything was normal up to this point
 Didn't try to extend it too far or anything and had just serviced the engine and filled the res.  with hyd. fluid.

Looking at the situation now, I'm quite sure I filled it with the wrong fluid. Did I do major damage?

[slimjim]

what was the fluid you used.

[mlappin]

It would take drastically the wrong fluid to do major damage in a short amount of time.

We had one combine that used ATF for the hydraulics and hydrostatic, the other one had regular hydraulic oil in it. Have several other tractors the power shift units use ATF, the local dealers say use hydraulic instead so we don't need to keep so much ATF around. Points is for example ATF and hydraulic fluid are somewhat interchangeable with hydraulic oil having a higher flash point.

I have a buddy that works for a local excavation company and he said they just leased a new Cat CTL that apparently the diesel and hydraulic fill caps look the same and on the new one they put the hydraulic cap where the diesel cap was on the old model so he put a few gallons of diesel in the hydraulics said they ran it for probably 3 hours before he realized what he did. He said they drained it and it hasnt been a problem so far.

It is bypassing fluid In one of three places in the valve with the handle or the cylinder or the pump or if it was really down on fluid it might be air bound crack the line on the cylinder

I used car quest or Bravo tractor hyd. fluid.  I think before I always used aw32 jyd fluid

When I get to work tomorrow I'll look it up on the computer and get back

[Big Wood]

did you change out the fluid and filter and start fresh if you got air bubbles in it crack the fittings on the cylinder and move the handle forward this help get the air out quicker then tell how you made out

[trz]

I may have overlooked the obvious. When I get home from work I'll check . You guys all probably assume I've looked at and iliminated the possibility that the connection between pump and motor failed but I didn't even think to check that.

[trz]

Well, I went home and checked the coupler, that wasn't it.

I didn't change the fluid or filter I only added two gals. of fluid.

 I've taken different hoses off and tried it , nothing seems to make any difference.   I finally fired it up and just held the handle in the retract position and it did retract ever so slowly. Held it till it moved aboutan inch or so and then tried the other direction and it wouldn't. extend either.  So, as of now I can get it to retract but its slower than a snails pace.

[Jwood]

I wonder if its anything like bleeding power steering where you crank it side to side but hold it after you turn it all the way when it bottoms out when the pump makes a different noise. If so retract it and hold pressure on the pump a few times?

[farmboythegreat]

maybe spring on relief valve broke
 has it a screan in intake port in tank , maybe it is plugged ??

[mlappin]

Where is the filter on this? I'm thinking it shouldn't be, but if it's on the suction side of the pump, that is between the reservoir and pump and if the filter is plugged there's you're problem. If the filter is on the return line from the valve (where it most likely is) then do like farm boy suggests and check the screen in the tank.

Most log splitters should be capable of producing at least 1500 psi, if it has oil to the pump no amount of air in a cylinder should keep it from moving.

I'm not disagreeing with you but automotive power steering pumps vary from anywhere between 300 to 2200psi just as high if not higher as a log splitter but you will only hit max pressure at full lock of the steering wheel which is how you bleed them.
