I have a MF 135 with a multipower hydraulic pump, I'm not getting enough hydraulic pressure to open my baler rear door to let my bales out, do I have to split the tractor to remove the hydraulic pump for servicing or can I just remove the top link and pull it out that way? or how can I increase the hydraulic pressure?

Has the pump meant this task before or
a new application? I believe that pump
only produces 120 psi for IPTO equipped
tractors and 190-210 psi for Muti-Power
tractors. There may be a test port
somewhere for MP. IPTO can be checked
at left side inspection cover.
The relief valve is fixed and only
accessible by removing top cover
(IPTO). I was able to shim the relief
valve on mine. Split necessary? Can't
answer that.

I have a MF 150. I'm no farmer and just use mine for general use around my woodlot and mowing. What port are you using to obtain hyd pressure? My 150 produces 2200 psi at the main pump. As I stated before that small muti-power only produces up the 210 psi. If this is truly the pump port that you are using, I can understand why you're having a problem. I've attached some photos. I use a diverter valve to operate the hydraulic Top Link on my 150.

Are you asking about the fittings or
the valves? Fittings are Parker 37
degree flare. Diverter valve mounts to
tractor just in front of seat right
side. Directional valve is 4 way,
closed center. Mounting plate is home
made, just flat metal. Lines are bent
and flared as needed.
