1971 TM400 Engine Gasket Sealer
« on: December 05, 2015, 09:30:17 pm »
Hello All,

 I am assembling a 1971 TM400 engine and wondering if gasket sealer is recommended on the new gasket between the 2 case halves, if so what product? There are no major imperfections but a few very light nicks in the aluminum.  I am more concerned with an air leak in the crankcase than transmission oil leak. I have the service manual which is very vague at best. Thanks Randy

loctite 515
3 bond
aviation gasket sealant
no matter what you use still put the gasket in, for the correct spacing of gear box shaft shims ;)

Thanks  for the replies guy’s. I guess I’m a little paranoid as I have not split the cases before. I have a can of Permatex spray copper and I think I will spray a light coat on each side of the gasket and call it good. The general consensus is with a gasket I really don’t need any sealer at all.

Wurth have a Threebond type instant gasket in a small pressure pack, much cheaper, easier to apply and no more wastage due to going off in the tube or nozzle. Think it was $36 for 300g can and trigger nozzle

Keep your gasket goo's in the beer fridge, in a plastic bag with a banana and they won't go off in the tube.

That Transit..........................I remember following a bus full of tourists on the dirt road around Opo with your dad full lock sideways on every corner at about 5km/h. Tourists didn't know what to think
