I have a 1968 MF 135 and the hydraulic pump makes a clunking noise, especially when the 3 point is under a load. A couple of people have told me that this is common with that vinatage MF and that it is the pump bucking against the anit rotation shaft. Anyone have any experience with this?

Many of the older tractors used sraight cut gears and often at the right speed or load they do talk. Normally that is not under load but maybe with a changing load. The people that you had asked I hope would have a good knowledge of those tractors and not be saying it because there JD used to do it to or make a simuliar noise. ....

Been a long time since I had a 135, but seems i remember if you raised the position lever too far up, the hydraulic system was in "constant pumping" mode and would knock pretty loud. Does it knock only in the fully raised position? ....
