Re: Leak free tranny - possible

These are questions that don't have an answer...You would have to do a long term road test under similar conditions with both set ups to determine definitively which method is best in terms of gearbox bearing service life, so we'll never have the true answer I suspect...

The purpose of the modification is to reduce/stop oil leaks through the bearing and having a single seal fitted seems to achieve that OK...
Removing the inner seal gives the bearing lubrication in the way that was originally intended and IMO there seems no logical reason to change that if early bearing failure is not an issue...

At the end of the day I suppose everyone must pick the theory they prefer...Ian
