Original 12mm wide seal on the left, new 7mm wide seal on the right, part # 90311-45014 original part for 1994 22R/RE. Installation on 1981 22R.




The flywheel seal bore also measures 12mm deep.

Because of the position of the lip on the new seal you'll want to position the seals face 1mm back from the front face of the timing chain cover, if you push the seal to the back of the bore it's lip will end up riding in the groove created by the old seal.
New seal installed.

This photo shows the proper depth so the seals lip will ride on an unworn area of the flywheel stub.

Used silicone to help seal between the crankshaft and flywheel bore.

Old water pipe connector and piece of pipe worked well to tap the seal in.

The leak has now stopped we'll see how it holds up.
