Rich from New York has sent in a question about his MF202. The hydraulic pump isn’t outputting any pressure. Rich has just bought the Hydraulics DVD and while it is in transit accross to The States he’s asked this question…
I have an MF 202 and Hydraulics do not work.
If I remove the standpipe cover oil flows out of the stand pipe but at no pressure what so ever (any position of the controls).Can you give me any hints to isolate the problem. Can I remove the side access cover and manually move the control lever ? Which way to rasie the lift ? How can I see if oil is blowing out of the pump releif valve. How can I check to control valves ?
Thanks

Hi Rich,
You can remove the right hand side cover and take a look what is happening (DON’T PUT YOUR HANDS INSIDE WHILE ENGINE IS RUNNING), you can control the pump with the quadrant levers when you do this (for safety) and make sure the levers are moving the linkage and control valve. On occasions it is possible to see an obvious leak, usually just an o’ring on the stand pipe but I have seen a split stand pipe before as well.
You say there is no pressure coming from the top of the stand pipe so that starts to narrow down the search for the problem. If the control linkages are operating the control valve OK then it could be the control valve which is worn (these are a very, very precision fit in the housing and must be near perfect otherwise oil will leak past it).
Or, presuming nothing is physically broken on the pump such as a yoke, then the pistons and cylinders could be badly worn and producing no pressure. Or the relief valve stuck open/broken (quite possible if you have a distinct lack of oil volume and pressure). Or last (but not least) there could be a problem with one or more of the valves. Oh, also there is the filter to consider, but unlikely to be causing those symptoms I think.
If the problem isn’t obvious from looking through the side cover then don’t worry. Just remove the top cover and pump as by instructions on the DVD and fully strip the pump. Inspect all springs, valve seats, pistons, cylinders, etc. Look for scores and grooves, check all o’rings. Take your time and inspect the components with a careful and critical eye. The fault will probably be quite obvious. A full pump refurbishment kit is not all that expensive, and probably worth fitting while you are in there if there is some general wear accross all the components of the pump.
Good luck

Steve.
I have a 1959 MF202. The three point hitch just starts to move the Gannon, but will not pick the Gannon up. Fluid is full and no water in the fluid. Any suggestions?
I have a mf 135(not sure the year) -older-and was moving a large roll of hay and heard a pop and the bail dropped, afterwards 3pt would not lift without assistance, added a little fluid to the cream looking floid in it to see if it would fix/help before I changed the floid, I asumed water? but it will lift now but will not lift with the speer on (to heavy) also on the 2 levers I used to leave the one in the same position (draft) now I have to use both ???? please help I am taking care of my dads cows and they want hay NOW THANKS!
thanks alot guys but still cant get the 3 point to lift at all changed the fluid i have to take the top off and check the pump hope to get it working great running tractor
wayne if its draining white in the hydraulic fluid there is water in there.. i drained mine out before just disconnecting a 2″ hose and using the bucket to raise the front end of the tractor. until there was no pressure
hi wayne i have a 202 industrial i bought it 3 years ago for $3400 .. i replaced all of the hydraulic hoses that go to the front bucket and i replaced the hydraulic pump filter thats located in the front behind the radiator grill. it runs like a champ! i use the hydraulic bucket to push down trees that are 8-12 ft high before i run over it with the brush hog at my ranch so the bucket on my tractor is very usefull to me
and the differential fluid.. i use 80w its around $13 a gallon at o’reilleys you fill the resivor next to the stick shift
I need to take some time and fix the rear wheel seals it has a slow leak from there
283 MF 1987 UK Hyd. not working at all auxiliary nor 3pt. cleaned filter installed diesel in unit to clean hyd. worked not great but worked. drained diesel filed with hyd fluid nothing again at top of tub small amount of fluid no pressure at all.
no theres not thanks for respoding
Hi Wayne,
Yes, all one reservoir. I’m not that familiar with these tractors, but don’t think there’s an external oil reservoir as well is there?
Steve.

Hello,
I have a 1979 MF 265 with hyd. problems. The lift is weak and shaking at the top of its travel. The oil is at the correct level. Is the hyd. pump located under the seat? What can I do to pin point the problem? Any help is greatly apprecieated. Thanks
