...just an update on the oakie oil seal replacement in my '47 torque tube.
It's a ton of work just to replace an oil seal. Chris Sweets tech tips was a huge help ! Anyone needing to do this will need to remove the drive shaft and make a tool to drive out the Oakie without damaging it. I used a 6 ft. length of thick wall pipe with a mandrel machined to fit inside the bushing. I do not believe it would be possible to pull the bushing out from the front 'cause it's extremely tight.
Anyways, the seal part # is SKF 10515. I machined out the bushing to accept two seals and put in a double seal.
