1000 throw out bearing - which is correct?
 

I am rebuilding the clutch on my 1000 and have a question about the throw out bearing.

I am looking at a couple of sources for parts. I see two different throw out bearings. The first is shorter bearing P/N IH-391237-R91 or 941-3056:

The second is longer and has a grease zerk. It is PN/ IH-106386-C91 or 703-0600:

My tractor has a short round section that has a grease zerk on it.

Which throw out bearing should I get? I would think that it would be the short one since my clutch already has a zerk on it. I thought I would ask here before I bought parts.

There is a serial number break for using the longer one, not sure what it is though.

That one is the correct one

There is a break at Serial Number 612808 .

Not sure what parts it affects?:bigthink:

How's that?:biggrin2:

The 612808 serial number breaks apply to items, 8, 27, 28, & 29


The throw out bearing (item #3) is unaffected by the serial number range. This according to:

The exploded view from the link in post #4 has the parts in the wrong order. The service manual has a picture of the parts in their correct order.

Am I correct in thinking that the longer bearing is for later model tractors?

the longer one is used on the 82 series. my 89 1050 uses the long one.

i converted my 108 over to the longer one, when i bought my new driveshaft from jeff i had him skip that hole and i drilled it for the longer tob.

Thanks for pointing that out, from page 2 - 23 of the service manual;

I took the clutch out this afternoon and disasembled it. This is what I have:

Yes, I know the throw out lever is incorrect. The original got trashed when my brother kept using the tractor even though the bearing was locked up.

The hole used to be round:

I think I'll replace the pivot pin:

I turned the pressure plates a couple years ago. They still look good:

This doesn't look good:

The disc looks good. It was replaced two years ago:

The teaser spring and cup were hanging up. When I stripped the parts off the shaft I found steps in it that were causing the clutch to not fully engage. This explains why the clutch was slipping:
