MF35 hydraulics overhaul - parts?

I bought the hydraulics repair video from the YT site and was pleased to see that the example they worked through was an MF35, so should correspond pretty well to mine. They convinced me that MF35s do not ALL drift and can be fixed if they do.

Question: where can I get the parts (preferrably in kit form so I'm not likely to not have something at the wrong time) at a fair price, and how can I be certain they are the right parts?

I know of the parts on YT, and there is a "Hydraulic Pump Overhaul Kit" for $134.48, and among the models it is supposed to fit is the 35. Here's the listing:

Hydraulic Pump Overhaul Kit - For FE35, TO35, 135, 150, 165, 175, 202, 2135, 302, 304, 35, 50, 65, 765. Hydraulic Pump Overhaul Kit contains (2) A-184471M1, (2) a-190799M1, A-180924M2, A-180925M2, (4) A-8992604M1, A-1810467M91.(Regular price $147.93, your cost $134.48) (Part No: 556601)

Anybody have experience with that kit?

I also have a relatively nearby Agco dealer who is my local MF supplier, but the last time I bought a part from him, it was wrong...and in fact, I think the same is true of the time before that.

My tractor serial number is 250583 and from the YT serial number listings appears to be a 1964 model. I do have all of the manuals, and of course, the video mentioned above.

Any help with an accurate list of parts and part numbers, supplier, etc. would be greatly appreciated.

Thanks!

Going back to the question - is the "Hydraulic Pump Overhaul Kit" for $134.48 (Part No: 556601) shown on the YT site the correct kit for my 35? My short experience with tractors tells me there are lots of variations in tractors of the same make and model, and I'd rather be sure than get a wrong kit and have to fool with exchanges.

If you do do the pump be sure to change the PTO oil seal, the first few I did all came back a few weeks later with a leak, it's not worth leaving for the sake of a cheap seal.

I can believe that these systems drift down due to a slow leak caused by the split in the piston ring. However, this is NOT a slow leak. From it's maximum lift to bottom, with no load, it can drift down when I shut down in less than a minute - maybe less than a half minute. When running and lifting a load - for example a brush hog - of course it drifts down faster, but I generally have to rev up to get it to lift at all from bottom.

It's really gotten to be too much of a nuisance. It gets worse in hot weather since the fluid thins, and while the new ring fix I mentioned improved it enough to satisfy me in geting through last summer, it's time to do it right. I could just switch to a heavier fluid in the summer, but I'd just as soon fix it and have it done.

Still looking for parts info!

Thanks for the feedback.

That settling is normal on worn machines - we've had it on all 5 of our 35's, and one 135. The others aren't worn enough. yet!

We had the single most improvement with new control valves. There are three precision fit washers on the valve body, and even minute wear seems to cause the problem.

The kit is a good idea too. Valves and valve seats are usually toast and the valve repair kits (ball inserts) are not worthwhile. A&I dealers sell Vapormatic parts among others, and our hosts (YT) are an A&I dealer.

A worn pump will blubber along for years, but the kit will bring it back up to snuff.

You've got to peel it apart to do it (top cover off - 4 hours, and you NEED an overhead lift for safety!) - and the kit is a small additional cost to do up the whole shebang at the same time.

It's a small investment to perk up a marvelous machine!

Good luck.

I bought that video too and found it very informative. You should also get Big Dean's CD too.
