Hi again guys,
thanks for taking the time to read and give information.
Our biggest prob at present is the 10 gallons of diesel fuel recently added to our hydraulic oil.
Pulled the main hyd pump and installed new seals in it with the help of my bud, put it back together again and no leaks. Then found the air bleeding procedure from service manual, and got started with the several hours of idling the engine, but had another setback.
Since acquiring our skidder last month, my partner has been filling the transmission with diesel fuel, thinking transmission fill pipe was fuel inlet. He couldn't understand why the level never dropped. After it ran for 5 hours I noticed a bit of weeping from the end cover of the hyd pump, no drips just wet, and it was very hot to the touch.
The hydraulics shop advised that we fully drain and refill the sump with new oil, change the hydraulic filter(s), run it awhile, and repeat that drain/fill/run/filter replacement exercise three times in order to dilute the diesel in the hydraulic system.
So now, gotta locate the drains and have earned there's several drains on the transmission sump. Is the lowest drain point OK, or gotta open all drains, because some areas of sump may not free drain?
Would anyone tell me the locations of both the hyd oil sump drain(s) and the hyd oil filter(s) please?
I've searched the service manual and the operator manual and can't find out anything.
This machine is a JD540 line skidder, don't know if it's an ' A ' or a 'B' - it's got a Gearmatic model 19 winch
When trying to bleed out the air from the steering valve, removed the bleeder screw and nut from the valve body, looked into the hole and saw the ball in the end, but no spring - it's item # 14
on the attached diagram.
Would anyone have information on that spring that sits between the ball and bleeder screw?
The bleeder screw hex, item # 13, was really chewed up. The original part seems complex and elaborate, can't figure out how it's supposed to function...hose connection nut is supposed to operate as a valve but doesn't function.
I'm wondering if it's possible to cap the entire widget off with a version to replace the OEM parts, which appear to be a spring loaded check ball.
