Reply to "help removing ZF"

I had it on 2511. It was a bitch to remove, but I pulled it and replaced it with an NOS true bronze piece.


WHY?

I had never heard it might be a factor in shifting motion, though


We went through the ZF twice and my input shaft was very polished on the end. I was sceptical too when Dennis suggested the pilot bearing, but the change over to needle roller cured all shifting issues.

Gary, this may be more a factor of the quality of the overall 'oilite' and oil content (should be around 25%). If too low then there is no lubrication and then the bronze will expand and is constrained by the block so only one way to go. I think the oilite material has to be machined carefully as well so as not to drive out the oil.
