Shimming Out The Rear Seal

[Diseazd]

Anyone got an easy way to move out the rear seal when there's a slight groove from the old seal on the rear crank journal? I was thinking about cutting a round shim out of good gasket material to shim her out a couple thousands! Guy

It doesn't have to be shimmed.

When you fit the new seal, just position it in the register so that the sealing lip rubs on a fresh, ungrooved surface of the crank.

Use a depth gauge to check it is reasonably square with the block and register.

Clamp the lower bearing register down carefully so you don't alter the angle of the seal and tighten as per Manual.

Once clamped in that position it won't wander and should seal as good as new.

Thanks Mate! I'll position it as you say. Do you install the seal then tighten the cap or do you install the cap and drive in as the factory illustrates?

I personally install the seal before the cap.

As long as you position it on a clean part of the crank and it is square to the block and therefore bearing cap, job done:)

In your situation, I'd be slipping the seal over the crank to where you want the lip to rub, then fit the rear cap.

That way you can see the exact location of the lip and be confidant it will be OK.

Make sure you lube the inside of the seal with engine oil before sliding it over the crank.

Tom Monroes' book has a section referring to this very issue.

Let me know if you need any more pics/info.

Thanks Nissanman........I've always installed the seal after installing the crank. I'll try it your way this time. Your car looks great! I couldn't open your photosite.......send some pics, I'd like to see more. My cars were featured in your www.viczcar.com. Looks like you Aussies have some great cars. Thanks again for your help. GUY
