Gaskets/RTV

Bud W · Oct 17, 2010

When installing a new gasket ( in this case the rear axle carrier gaskets on a SC )do you recommend buttering the gasket with a light coating of RTV or should I leave them dry?
Thanks

In a perfect world, the RTV is not needed, but when dealing with a 50 to 60 year old tractor, the RTV may not be a bad idea. For sure, it will not hurt anything, and might just mean the difference between the gasket sealing up tight, or having some pesty little drips.

When installing gaskets, I thoroughly coat both sides and edges with grease -- a method I learned from my father.

This allows them to slip/slide as you tighten them into place; conditions them to be exposed to oil and, most importantly, they are not destroyed when you take the pieces apart again to install the @#$% part yoou forgot!

On most gaskets I use some RTV or silicone. 2 reasons for that. Old parts that are stamped steal get bent a tad and #2 to help hold the gasket in place when your installing parts.

I sometimes use #3 aviation form a gasket. It's kinda sticky too. Recommended for aircraft engines which you don't want to spring a leak at 10,000 feet.

I use heavy grease on most gaskets. It both helps seal them and holds them in place. On gaskets around water (water pump, thermostat, etc.) I use avaition cement. Something stamped steel, say a crankcase front cover that could be bent or warped a bit might get avaition cement too. It"s pretty much a personal preference thing. A light coating of rtv would keep it in place and help seal it up. AG
