MF40 Hydraulic lift cover/controls

JBKINWA · Dec 9, 2016

I am running into some difficulty finding the right parts and procedures for repairing the internal hydraulic system on my tractor. I believe it is a late model 40 industrial S/N 9A207276, (1974?) I have a set of reproduction manuals I purchased last summer, but they do not include any service bulletins or updates. I also have an original dealer manual, same thing. Casting number on the lift cover is 1869284M1, control support is stamped 898197M1. It has a 3 3/8" lift cylinder and does not have a mounted dashpot. Does anyone know a source besides AGCO that might have the information?

Just wanted to add that the model information is not on the data plate. It should be a 40 not a 40B as it has the 3cyl. perkins. The pump is a 21 spline model(868439M95) with a 868471M91 pressure control valve. I have to replace the lift cylinder and most of the parts in the control assembly and was trying to find the correct breakdown. Thx

Try, Glenn B. Dorning, Inc 909-983-2089

They used to deal with MF industrials, and they helped me with parts for my MF industrial. They maybe able to help you.

Thanks, I hope they can help. This project is still an ongoing challenge. The internal hydraulics have not been used in a very long time. The tractor had a platform and receiver hitch bolted on the back. When I tried to compress the hitch cylinder on the bench I found it had been pumped full of grease. (to keep the arms up and out of the way I guess.)

I found an archived web page that listed a lot of Industrial models and S/N's. By this list it is a late 1974 MF40. 1975 was last year of production. The 40B didn't start until 1976. I know this topic surfaces from time to time.
