The right side Control Shaft Bearing Part No. 526 860 M1 on my MF14 is shot. First of all, does anyone know where one can be had. Secondly, just taking a quick look, I can't see how to remove it easily. Has anyone ever replaced one and if so, can you give me some pointers?

That's those flanged bushings, with a flat on the smaller diameter, right? There's 4 of them in total that fit from
the inside, into the frame. The other 2 are for the deck lift. They are made from some sort of cast white metal, and they break. Brittle.
NLA. You'll have to get them made on a lathe, out of bronze, and file that flat on them.
Unfortunately, there is no easy way to replace them if you want to keep it looking original. You'd have to
free up all the linkages that are well rusted on to the shaft, and take it apart.

On my MF14 working girl, those bushings were shot, so I made up bronze bushings and slid them onto the shaft from the
outside. I then drilled and tapped a hole close to the bushing hole and used a 1/4" bolt and washer to hold the bushing in place.
I hope the descprition makes sense. If not, I'll take some pics.

That's what I was afraid of, wish I had a lathe and knew how to run one. Thanks for the information.

I machined mine out of aluminum on my CNC mill. I should have made a bunch I guess. I don't have access to the files right now or I'd post them.

I used to machine them from aluminum also...perfect match to OE. They worked great.

I don't have my MF14 handy, to measure, but I would think you could get a bronze or alum. bushing to those measurements
from a bearing shop, and then file the flat on it. Considering what it does, tolerances aren't that critical, if you just
wanting to make it work again. Just like every other dimension on these GTs, it's more than likely nominal, and a hole drilled
into round bar stock would suffice. Thats one of the great things about these old tractors. Everything is done with fractions.
Plus or minus 1/16"

Mac, you should fire up the CNC, and make a swack of em. Post it in the sticky for parts. This will be coming up again.

you dont need a lathe, Simplicity sells the same size bearing just have to hack saw off a little length, file down a little shoulder to bring the flat spot back to the flange and wala you have a oil and graphite impregnated bushing. These bushings are sold for older sears tractors and late model broadmoors. Simplicity part number 1713167, Stens part number 225-817. Two will need to be drilled out to 7/8 ID, the other two are right at 3/4 ID, do your self a favor have the shaft hydraulically pressed off, otherwise you'll destroy it. BTW these bushings run a little over 5.00 each. I believe there better than the factory aluminum, and probably better than bronze with the oil and graphite impregnation. Good Luck

yeah the guy has helped my buddy Garoyl, hes got some cool videos on you tube also. He actually found 4 Massey Fergusons MF14s for him, one with a factory three point, all in one month and within a few hours drive, I think the guy must smell Masseys, not sure how many he has or had, but I bet hes found twice that number for others, I met a guy at the Republic Mo tractor show from Cape Fair Mo that knows him, he calls him Highway, like the movie heartache ridge or something like that. someone told me he was a liitle out there, but that pretty much describes anyone who doesnt take any gruff, I'll reserve judgement until I find out different.
