So I have been busy in the garage I got a 1.25" predator track this season and I am finally getting my entire skid powder coated for a good price so i had a week or so to do other things.
when i pulled my skid/old track bearings were rough. My speedo worked fine but that bearing on the PTO side of the drive-shaft was frozen and on its way out. I did all 4 I hate doing things 2x and it was easy enough.
Well I remember seeing a post from 109jb on arctic chat and he did a entire bearing write up and took pictures of the sizes for you.
Thanks to him i walked in and out of farm and fleet in 5 minutes with new bearings (they are in the agri/tractor area) lol
Other than needing a few different pullers (my lower chain-case bearing did not "fall right off" lol) it wasn't that big of a deal i feel like anyone can do this.
The few tricks are just centering the Drive wheels to tunnel and jack-shaft (don't fully lock the collars on the bearings until you measure your clearance and gears. as long as you mark where you took the old bearings off it was easy my chain-case lined right back up.
Moral of the story its worth doing and not too hard. Makes me feel better about my drive-train.
