mf1250 4x4 problem

[dbail]

I have a mf1250 my 4x4 stopped working, and the tractor was making a grinding noise I had the tractor fixed it was the rear bearing on the 4x4 shaft.$2,500 later, i ran the tractor for about 10min and it happen again.this time i tore it apart myself.the bearing was destroyed again.the shaft was pushed through the bearing and into the bottom transmissoin filter. when i was ordering parts i talked to the right guy.he said he had heared of this before he thought they had all been fixed.he said the shaft needed to be shorten.he said i was lucky it didn't break the rear housing.I don't feel lucky.if anyone has a mf1250 you should check this out before it's to late

I just got a 1998 MF1250 a few weeks ago with 1033 hours..

I have perked up a few cosmetic things and much improved my starting by cleaning the battery posts and all connections. When the temperature is below 30 F I hold the glow plugs on for about 20 seconds and it fires up on the first crank. When it's colder I hold the glow plugs on for about 30 seconds. Before I cleaned the posts and connections It was a very hard starter.

I digressed.

What did you do to check the problem and what should I be looking for? Any pictures? How long should the shaft be? The shift mechanism for my 4WD is VERY stiff. Is there a way to loosen it up? Is this a precursor to the shaft problem ruining a bearing?

Thanks for the heads up.

they start hard in the cold, i use a block heater. the space between the front shaft and rear shaft should be about 1/4in.when you cleaned the trans filter was it damaged? i would send pic, i don't know how? when i click on insert image it wants a url?

you should be pushing the clutch pedal down before shifting the 4x4 lever and stopped

We have a MF1250 in the shop right now little over 1200 hours on it, same issue dbail had. We have it all torn down to nothing...big job. It actually began to chew away at the transmission casing so this one had been bad for a while. Tech is saying previous ones he did were close to 40 hours labor. He says you need to shorten that shaft...I'll let you know how much when we go to put this one back together...good luck

If the shaft needed to be shorten, wouldn't there be some sort of a recall or bulletion on this ? can anyone confirm ? My father has mf1250 as well - i remember several times when he was towing my 16 ft trailer loaded with firewood from the feild, i can hear some clicking when in 4X4 turning. Is this normal or the warning sign that it needs to be looked at ? it works just fine right now. MY father thinks, if it aint broke dont fix it. I am more a preventive type of guy. So either way we gotta know.

Thanks for the "good" news.

My 1250 is a 1998. What is the year of the one in the shop? Does that make any difference or are all of the shafts too long? Or, is it only a problem for the tractors shipped to New England?

radioman; next time you change the trans fluid you can remove the front 4x4shaft.you can slide the couplings back and hold the shaft in place and see how much space there is between the shafts.mf should flag anyone who buys that rear bearing that the shaft needs to be shorten. they don't !
