Goofed Install of Flywheel Oil Seal
 

After installing the flywheel end seal and joining the case halves the seal came out of position. Used Curil T in the first instance.
On making a tool to assist with the second install of this seal with the engine assembled, and using ThreeBond 1121, the seal is now 3mm out of square. 1mm in at the bottom and 4mm in at the top, (from the case edge).
I see this as a potential problem oil leak as the seal would have to do considerable more "wiping" of the crank.
At the top, the seal is installed flush with inner of removal slot.

Please confirm that seal must be removed and fitted square. Best method of seal removal, bearing in mind that the seal is flush with the inner of the remove slot.

Thanks Paul

Yes, remove it, or it will leak just like mine did the first time. I also think Curil-T is your enemy here. It goes in easier if the outer part is dry (doesn't keep popping out). Make sure the inner seal and c'shaft are oiled. You don't need to add sealant to the outside, it seals just fine. A small block of wood is helpful to tap it in, but the seal install tool is pure heaven.

I don't think there's anyway to remove it without destroying the seal. It suks, but pay now, or remove the engine again, and pay later.

I've been, there and feel your pain.

I have had some bad luck with Curil T also with the pulley and flywheel seals pushing themselves out overnight. Install the new seals dry. You may be able to use the old seal to help in installling the new one.

Been there too.

Thanks gentleman
The old rear seal has been removed and even better a new seal installed, without sealant to case, correctly I trust.
Thanks again, Paul

What is the part number for the tool when used with the 964 case?

HI Chris the tool is the same as the SC/3.2 in the photo.

And for those of you on a budget or can't wait for the OEM tool, try an oil filter cap-style wrench. The pictured one is made by Flotool (Super Graphite model) and was purchased at some local store (NAPA or Farm & Fleet) for a coupe of bucks. Use the old seal to protect to new one as you work it into the case.
