SM420 PTO cover

[Bill Hanlon]

Anyone know where I can buy a PTO cover gasket for an SM420 transmission in my '52 GMC 150? Mine is leaking a bit.

Tried Classic Parts and Novak's web sites with no luck.

Rock Auto lists Felpro TS5100 but doesn't say if it is for a 3 speed or 4 speed. Picture looks to be for a 4 speed.

Couldn't you just make your own gasket or use try using some Permatex 81160 High-Temp Red RTV Silicone Gasket for it? The guys replacing the rear-end pumpkin cover use just a silicone gasket maker. That is what they used on my 342/1 when they put it in.

Try Novac.

Gaskets

Me , I'd scrape & wire brush it HOSPITAL CLEAN then lay a thin 3/16" bead of Permatex " The Right Stuff " ~ you have to try this newfangled stuff to believe it ~ nothing else comes close .

I use it everywhere now and never a leak weep nor seep ~ that's saying something when it comes to 1930's Tech engines .
