In Reply to: Yanny 155D Hydraulic Screen Location? HELP? posted by Jason on Monday, March 17, 2008:
Thought you might know!
My 1978 yanmar 330D (total 1500 hours) has a lazy lift
capabilty. Stick the bucket into a pile of gravel and
it's lazy about lifting it. A friend says the system
needs increased pressure, to turn the screw on top of
the spring a 1/4 turn at a time at the hyd control and
see if that helps. Well the cover is like very smooth
surface, not hex headed and no way to get at the screw
adjustment. Like it's preset for tension/pressure. any
ideas??
Also I have put 32 weight hydraulic fliud in the trans/hydr. I'm seeing that's a no-no. should be JD hyd/trans fluid, right??
Thanks, Larry
