Does anyone know where I can get some?
I know this is a drive train subject but it is a Big Bolt specific item. I will post there as well. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy Jim Sears, I believe that rear axle brand is spelled Timken. Call a shop in your area that rebuilds large truck transmissions/differentials, explain what your looking for, they may be able to help you track down the parts you need. Is that a Timken double reduction diff.? | | | | | Joined: Jan 2013 Posts: 1,384 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 1,384 | Yes, typo. It is a double reduction.
Checking local heavy shops is a good idea. | | | | | Joined: Jan 2013 Posts: 1,384 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 1,384 | The local truck heavy truck shops seem to think it is extinct.
Manufactured some shims to finish the assembly.
