[Es2] Rear Main Seal install

[Tom Saltino]

Nathan,

You are correct the flat surface faces the flywheel.  

Also, the factory install tool make the install job easy and seats the seal at the correct depth.  I'd be happy to loan it to you if you would like to use it.  Send me an email off-list.

Tom

Subject: [Es2] Rear Main Seal install

Got my donor engine back from the machinist a month or so ago, and I just
started reassembly last night.  My question is:

What orientation should the rear main seal be installed in?

There is a flat on one surface, and on the other side it's cupped with a
spring around the ID of the rubber crank sealing surface.  I'm thinking
that the flat should go to the outside of the engine, but I want to be
sure before I proceed.

The bentley is unclear about this, and the family album drawing isn't too
clear either.

Thanks!
