Paul I think John would be speaking of the crucifix seals since the bearing cap would be removed to replace those. I don't think any harm is done with the crank stub seal. I was going to mention it too but life has me busy and Tom did the right thing leaving the crucifix's alone.

 

There have been some posts recently that the rear main doesn't leak as often as the cross seals:

Jafir, I actually thought that Dweb thread was the one where John made the comment. I know it was on a fairly recent thread.

 

Well it did not appear to be leaking from the bearing cap, just the crank , my guess is if you remove that cap to do seals when you reinstall and torque it with new seals/sealant it may be slightly off compared to previous causing bearing to tight or loose so very slight you would not notice it and leading to failure

When I get a minute I will read the threads above thanks for the info guys
