Hi All,
1st post on here, I'm hoping you can assist me!
I have an 04 Rockster with a leaking rear main seal. I'll keep this as brief as possible as I'm on my 4th seal and its still leaking!
Summary:
Internal seal replaced, looks dry when outer seal removed
Outer seal replaced, 3 times. Have ensured the seal is flush with casing and installed with lip inverted to clear the crank breather.
Each time I replace, the seal leaks, it looks to be from outer edge and not the internal part sealing the crank.
Have checked the oil breather and this is clear.
I have been told it could be the worn crank bearings forcing an elliptical rotation which could put some pressure on the seals and cause the leak. It looks like a small leak has now formed on the front main seal so this does support the bearings as the possible issue.
Questions:
If worn bearings, I would assume the inner main seal would also leak?
Could worn bearings lead to a leaking rear main seal
anything else I need to check?
I do have pictures, video etc I can upload if anyone is interested.
its super frustrating, any guidance is much appreciated!
