New to this forum so hoping people can help.
I have a '69 MF 135 (gas) which was having trouble lifting the FEL. It was a very slow lift and would not hold its position but eventually drop. The three point hitch always responded strongly.
I deduced that it was probably the cylinders bypassing because of worn seals (I did do a bypass test on each cylinder to confirm). Because they had been on the tractor for untold years I decided to replace them altogether.
Now for some reason (stupidity on my part I expect) I decided to remove the remote hydraulic cover plate (sits to the right and slightly in front of the seat) and upon lifting if obviously dislodged the pipe that runs down into the hydraulic pump.
Well, I reattached the plate (making sure that pipe was seated correctly) drained all the oil,cleaned filters etc and put the system back together with new cylinders. Once filled with new fluids I started the tractor and now I have no hydraulics whatsoever.
Normally on start up, the three point would rise into position, but now does not budge an inch and there is no life in the FEL (I ran the engine for awhile and cycled the controls to ensure that any air was bled though).
I took the remote hydraulic cover off again and noticed that although fluid was raising up the pipe, it was very weak and slow and easily stopped by me putting my thumb over the end of the pipe and I could not feel any pressure being exerted against my thumb by the fluid.
Any thoughts as to what I might have done?
