Sprocket stuck on final drive

Post by reedgmi » Sat Mar 22, 2025 11:17 am

Man, what I thought would be one of the easier tasks .... unbolting the sprocket from final drive flange.
How much acetylene & PB blaster can it take?

Mine came right off with no effort. Perhaps the dowels are seized or even welled over?

Dowels are only thing that can be stuck if the bolts are out.

How about loosening the bolts a bit and driving around the yard? Works on old car hubs, wheel nuts etc. Sharp turns might put enough stress on on the rust between axle flange and sprocket. Be careful and check frequently.

I used to use just a sledge hammer, but many years back I got a "dead blow" plastic sledge hammer. Way less ringing in the ears beating on sprockets! :lol: Lavoy
