Final drive reseal and brake question

Postby Sterff89 » Sun Apr 02, 2023 2:55 pm

My brakes on my cub have been squeaking, and I have a few drips from my final drives, so I decided to take them apart while I have time. I am going to do one side at a time and started on the left side. I just finished this job on my 51' Super A so I learned a good bit on that project. I have the final drive completely disassembled and have two questions. Is it normal in the second picture for the band to rub on the drum? Also on the toggle piece I believe the one knurled pin was replaced at some part with the pin on my vise and was peened over. Can the original pins still be bought or could I use a roll pin? The factory pin measures .245 and .255 at the knurled part. I ordered all the parts and I'm waiting on a bearing splitter to press the axle shaft bearing off. Thanks

I'm pretty sure that those anchor pins are no longer available new from CaseIH. I'd give JP Tractor Salvage a call and check on their availability used.
Yes, it's normal for the band to rub on the drum.

Agree with Bob on the rubbing...most of mine show some. :? You MIGHT try bending the band near the lining, but you take the chance of its not fitting back inside the final.

If you haven't checked/replaced your gear oil in your transmission recently, it MIGHT be overfilled or have water in it, raising the oil level above the axle seals causing the leaking.

I did change the gear oil when I bought it about a year ago and it looked like caramel syrup. I did drain it before this project and the level seemed to be right at the level plug but, it was watery again. I'm planning on pulling the rear cover to seal it and the pto so I may try to clean it up a bit. I did struggle to get the differential bearing retainer out to change the o-ring though.
