Lquid gasket?

[Kris]

Anyone tell me please if threebond is ok for a liquid gasket and if so, which type for the bike? its for a woodcraft engine cover..

Thanks :)

cant help you on the threebond but can i make a suggestion

you can buy gasket sheets where you can cut out a gasket, mush cleaner and neater than gasket goo. Makes it much easier to remove if you ever need to and gasket goo can ball up on the inside of the cover and go an clog something you dont want clogged.

i think an AMCN had a story on it a little while ago.

Be careful to use the threebond (yes, it's good stuff) that does NOT solidify... otherwise as Lopeman wrote it'll clog up oil feed lines and thats really not good :)

There's a stack of different options at your local supercheap...

I agree on the gasket making.

All you need is a very small ball-pained hammer, a hole punch and a sheet of gasket material.
Lay the sheet over the case cover and gently tap around the edges of the cover and the gasket will fall away to the exact shape of the cover.
Do the inside edge of the cover and bingo!....your very own gasket.
Mark the bolt holes and punch out where you need. Easy.
You can use a very thin film of Permatex goop but not overly needed to supply the seal itself.

Cant beat gaskets for that type of job.

Making a gasket isn't hard BUT most modern bikes side engine covers are made to a machined seal so you need to use gasket goo. If you use a gasket you then change the mounting position which might cause problems with clutch engagement & stator alignment. Yes granted we are only talking about .5-1mm but they are a machined seal for a reason.

Any good quality liquid gasket will do, silicon based is better for when you need to pull apart again & clean sealing area, the bond stuff is a bitch to clean surfaces.

Thanks guys, I have made gaskets in the past but the product states as Roy has mentioned to specifically use a liquid gasket.. Seems the Threebond is the go..(it mentioned Yamabond, which i assume is the same)

Assume ill just get the highest temp one available as the oil is exposed to the cover/material...

Locktight do make a high quality liquid gasket that works well and peels off easy. But it is not their normal thread lock stuff

That is what I use & the bonus is it's blue

:ayyy:

all my polished engine casings were removed, polished, and refitted with high temp silicone.
No drama's at all, even if bike being no stranger to heat.

Too right, till you discover how well acetone just wipes that stuff up like.. well.. I dunno, but it really wipes that stuff up easy :D

Read the temp ratings... some of that can seal exhaust manifolds, you dont need that temp rating.

Blue maxx it is, up to 260degrees designed for rocker covers etc :) Local repco has it.. and the body filler i need for my fibreglass repairs... ;)

acetone huh thanks for the tech tip jasonbw .....good to know ......have spent some wasted time cleaning that crap up

[phillmac]

When the good shit is used in a very thin layer and bolts are tensioned, If no blobs get squeezed out the outside then chances are none will be on the inside. Used to rebuild Roots blowers that stood about 5' tall and the gasket for the huge top cover was a thin smeer of silicon with a single cotton thread run around in the centre of silastic
