Flywheel seal installed dry or OD with sealant like Curil T?

Dropping the '83 3.0 engine (again) due to a flywheel seal leak and I would like to know if it is best done without a sealant on the OD or perhaps with a very thin application of Curil T? I used a thin application of Curil T just recently on the same seal, and it seemed to make the seal press in with too much resistance.
I did not like the way that last seal went in and I should have started over without this second engine drop. http://forums.pelicanparts.com/support/smileys/paddel.gif[/img]

I have 2 seals on hand this time.


Thanks in advance for all the guidance and help.

You'll find many opinions on this because it's a personal choice. I never use anything on the outside of a crankshaft seal I put a little oil on the inside running surface. The most important thing is to use the proper installation tool. There's a guy on this board who rents a seal installer for $20.00.

I used a small amount of Curil on the OD and small amount of grease on the ID. I do have the proper tool for installation if you need it.

dry. curil t never dries and you need a decent grip between seal and case so the seal doesn't get pushed out.

if you don't have the "proper tool" a $2 PVC pipe from home depot works fine. someone posted the correct diameter which can be found in a search.

Listen to the man. Probably done more 911 crank seals than all of us DIY'ers combined.

I just wet the seal with some water to help the seal slip into place, to avoid tearing the seal's rubber covering if it gets slightly hung up on the case bore going in.

Well; time will tell if my method worked, but I lubed the seal with a little bit of motor oil on the install: using the 2in dia PVC pipe and my hickory mallet.

It's in and I opted for dry on the OD with oil on the ID. I decided to put the seal in the freezer over night and the seal went in nice and square and flush.

Thanks again!

Freezer trick works great, did the same when I replaced my ICAM seal, first time it snagged and dirtied up my clean engine

Yes... it was still plenty flexible on the ID and it started in nicely and went in square and true.

Jim,

You could install the oil seal dry as is or with some Curyl-T. Both method works. The key to a successful installation depends on the method and technique. The flywheel seal should be mounted straight from start to end using an appropriate tool or device. I have been using my home-made PVC tool with three bolts for installation with good results. Much better than using rubber mallet and a piece of wood.

Make sure you de-burr the bore, get it nice and smooth. I screwed mine up the first try using a home made tool. Next time I froze it, ran outside and it slid in like butter. Some say to go deeper, or not as far depending on if you see a groove.

If you have the Porsche tool, it doesn't get much easier. Just wet the OD to let it slide in easy. DON'T use Curil T.

My first one was set too deep and leaked. Dropped engine again and installed second one a little shallower and no problems.
