cylinder base gaskets
 

Anything wrong with using 2 or 3 of the 0.25 mm gaskets rather than single thicker gaskets to adjust deck height? I have a pile of the .25s in hand.

Thanks

Brian

Shouldn't be a problem.

Less is best.
If possible use the least number of shims/ base gaskets you can.
When you start to pile up base gaskets it becomes easier for the gaskets to squeeze out.
We try to limit base gaskets to 2.

Supertec website has base gaskets of various sizes.

I'm measuring a deck height with no gaskets of about 0.9 - 1.0 mm, so I hope that two will be all I need. Should they be coated with a sealant on both sides?

1.0 mm is .039 inches. With one stock base gasket you would have .049 inch. For most applications that should be enough.
If you need .050 base gaskets we have them.

As for sealant we use a thin coat of Curil T on both sides of the gasket.

Thanks Henry. Since two is okay, I'll use what I have in hand. I may tear it down next winter anyway, so I'll remember you have the thicker gaskets.

My cylinder base gaskets have a black coating on them do I still need to use the sealant?

Just use the Curil T as Henry suggested (or Curil K2 if you have that lying around), as that's been the standard procedure I recommend to all my customers for sealing the cylinders against the case, even if it's been o-ringed. I'd rather be overkill than have a leak when everything is said and done :-)

OK Thanks!!

What ever you use to seal the cyls. make sure that the curing time is long enough for you to be able to torque those cylinder heads,ThreeBond 1211 gives you about 90 minutes.,cheers,Sonny.

Curil T is non hardening. It will still be soft after 2 years. That is why it works so well for cylinders.
