Ive owned my MF65 for 30 years, its a 1960, hydraulics have been mostly trouble free except for 3point hitch slowly dropping, still functional & I was able to work around it
In December hydraulics stopped working, I pulled draft control, I have the dual spool, & replaced o-rings on stand pipe to no effect, as it was winter I chose to wait till spring to take apart
Ive now removed the hydraulic pump, found what Ill call the canister, (which is where later years must have the filter), crushed with an accumulation of steel grindings on the bottom, I dont think this was the direct cause of failure as it looked to have been ground up while still running probably damaging the pump leading to eventual failure
Im going to install a new pump,
my question is the cause of the 3point not holding pressure, the work cylinder
& piston move freely, not sure how to determine if thats where 3point could be losing pressure?
It would be nice to have it function correctly. I see theres an o-ring between the work cylinder & the lid, I dont see a part listing for that, is it the same o-ring as on the standpipe?
