165 lift

joe201 · May 29, 2015

Please, don,t hold it against me but I'm a ford guy, and don't know anything about MF . I took a couple of bush hogs over to a buddies place for repair and had quite a time unloading them with his MF 165. It must not have live pto because when you pushed the clutch in the bush hog would start dropping fairly quick, if you shut the tractor off the lift immediately drops. And probably only lift about 400 pounds. He has a book on order just wondering if any of you guys could kinda point me in the right direction trouble shooting this problem.

Thanks Joe C

The clutch is a 2 stage unit. Half way down will stop movement, full depress also stops pto.

I suspect that the lift cylinder is in need of attention. Take the lower bolts out of the right side inspection cover and drain oil to that level. Remove cover and observe oil coming from above while tractor is at idle and lift is in the mid raised position with a load on 3-point.

The lift cover will need to be removed to access the lift cylinder. The cover is HEAVY. Do not remove the four nuts under the seat, they hold the cylinder in position. You will also NEED to remove the cam roller before lifting cover. I use tag wire attached to roller SO it doesn't fall into the belly of the beast if I drop it.

Hi Joe,
There are a number of things or a combination that could cause immediate fall of the 3-pt linkage when drive to it is stopped. As Tom has said the lift cylinder is a strong possibility. Add to this wear in the pump valves and control valve, leaking O rings on the stack pipe (More later) and even oil that is too thin. The pump is situated in the bottom of the casing. On the hyd cover is a small plate retained by 2 7/16" bolts. A pipe connects the two. If the tractor has Pressure Control (look at the front hydraulic lever quadrant) you will see 'Pressure Control' stamped in it. On non-PC tractors the pipe must be lifted out fully before the cover is removed. On PC tractors the pipe can only be lifted about an inch to disengage it from the pump. There is an O ring and a white PTFE washer on each end. A split O ring can allow enough oil to pass and give the problem. Otherwise it will be a removal of the cover and probably the pump.

Thanks for all the input , I think that I'll wait until the manual comes in before starting on repairs.
Thanks again Joe C
