1200 Throwout Bearing Differences

[Texas Blues]

Howdy folks, I need some advice. I see vendors selling three different looking throw bearings. One of them, is the OEM looking one, like the one I have in my tractor. The other two have taller inside races. The sellers say that you can use these taller ones just fine. Could someone explain to me why these are different? Will the taller ones effect spring pressure? Here are some pics of the different ones I have been seeing. The second picture shows his taller one next to the oem bearing. The first picture looks even taller than the one in the second picture. The third picture looks like my original bearing with the metal cup around it. Can these taller ones be used without any other modifications? Any help and advice would be appreciated. Thanks, TB

the top pic is what i have and it required drilling a new hole for the pin that the spring rests against, the one in the other pic should work with the stock holes but will increase the spring pressure which isnt really a bad thing.

Thanks olds. That is what I was wanting to know. On yours, does the bearing come off of the center sleeve? If so, that would be nice to be able to replace the bearing cheaper in the future. Thanks again, TB

yea the bearing can be pressed off and replaced for about 10 bucks

Great question. I wondered that when I redid the clutch in my 800. Took a bit more spring press to get the roll pin in because of the longer shoulder but ended up working out fine. That one with the grease fitting is pretty long, wow

I thought those with the long shoulder with the grease fitting were for the 82 series gear drives?

somehow this is incorrect for a 1200....

the one with the grease fitting requires you to drill a new hole further back for the spring to rest against to make up for the longer bearing, works great in my 108. i dnt know that there correct for any tractor because there made for pullers and there a great upgrade

Thanks again olds. I made my own driveshaft and drilled the holes in the standard configuration. I can just as easy build another shaft and move the hole for the pressure spring. Could you tell me approximatly how far back you drilled your new hole from the existing one? Thanks, TB

[olds45512]

I simply measured the difference in length from the new throw out to the old and drillled the hole to that measurement minus 1/8 inch just to give some more spring pressure.

Thanks olds, sounds like a plan. TB
