G'day all,


I'm hoping someone here will be able to help me out.  I've just noticed a "second" seal on the back of an EA81 crankshaft. There's the usual one then between the bolt holes and the flywheel centring ridge is an orange seal.  

My local parts joint only have one number for the EA81 rear main seal.  Do I need to replace this orange seal or just leave it?  It's not leaking but while I'm in there it's usually worth doing.


Any insight or thoughts on this appreciated.

just leave it unless it's noticably damaged.

I have used these over lots of times and never had a leak or any problems. I would get another one if it's damaged though.

Thanks guys,  that was just what I was after.  I'll get a new rear main and leave that other one alone!

Why is it there anyway?
