Not easy without splitting the engine cases. The old seal can be removed with screw driver and hammer, rough but effective. New seal installation is the big issue. There is a ridge on the outer surface of the seal that sits in a groove in the cases. Maybe a press can push the seal home.

I'd always thought this was a bigger job than it looked - this is the output seal isn't it?

I don't think it goes in form the outside - have a look at the service manual and find out what that says.

And welcome Andy...it's the place to find out the answers ;)

I always thought it was a engine out/split cases
