Throw Out Bearing Fitment Issue
Posted by: Freeman ()
Date: May 13, 2019 11:52AM

I am switching out my differential with one that I reconditioned a few years back and my existing throw our bearing will not slide on to the new shaft. The bearing has no more that 3,000 miles on it and the shaft is a new Clark's double seal shaft. The shaft that the bearing came off of is also of the double seal type installed around 2009.

I have taken several measurements with a digital caliper and most are spot of or are within 1 one hundredth of a millimeter of each other. I don't know how it would have happened but the only thing I can imagine is that the new shaft is someone out of round but, it's not visible to my eyes.

Any experience or thoughts on this would be appreciated.

As long as the bearing slides easily! Use some Emery Cloth

Taking measurements around the snout should show if it is out of round.

Push that in./mm button, we speak 'merican around here. grinning smiley Yes, we are old.....winking smiley

Like Matt says, if it slides, all is good, polish the snout with a strip of emery cloth/sandpapaer like shining shoes until the bearing slides easily.

Agree on the in./mm button but I use it so much for measuring stuff on metric motorcycles that I have just gotten used to using it in that mode.

I was hesitant to do the emery approach but I will give that a shot and see what happens.

Thanks!

I did the emery shoe polish thing follow by 600 and 800 grit sand paper then scotch brite and all is now working as it should. I just worked on a 1/4" of the tip and that did the trick.

Thanks Matt and Frank for the suggestions and encouragement.

If you haven't taken the old differential out feel free to bring it by and use my lift.

Thanks for the offer Joel. I had already taken the power pack out last week and put it all back together today with the help of my EZ Lift and an ATV jack.
