Fitting paper gaskets
« on: February 22, 2021, 04:20:10 PM »
Do you fit new paper gaskets dry or put someting on them?

Got a new gasket for the clutch cover on my T125 Suzuki. Horizontally split crank cases. All gasket surfaces perfectly clean and like new.

Do I put the gasket on dry or put something on it? What is good practice?

And what is the best method to tighten the 6mm JIS screws?

Ive done this dack in the day, and recently, but just wondered what the general opinion is.

I've always used a smear of grease on both sides of the gasket and a 'T' JIS screwdriver, be interesting to see what others do.

Same as above.
Grease both sides.
Helps the gasket settle evenly, aids future removal and possible re-use.
It also seals the gasket to prevent against oil wicking if it is slightly porous.

And it helps hold the gasket in place while fitting up the cover.

Depends on the condition of the gasket surfaces but generally I do as others above say, gently massage twixt thumb and forefinger grease onto both sides, (and the gasket  :D), this is quite beneficial with carb gaskets as the ones I use are generally paper based as I make my own.
