AC B final drive gaskets

Carl Cramer · Jul 30, 2009

Finally going to replace the gear oil in my B's final drives, after too many years. What's the best way to replace the gaskets? Can't seem to find pre-cut gaskets online or at local tractor store...so do I cut my own cork gaskets from a sheet....or should I use a fat bead of RTV sealant?

Thanks!

When I did them on my C I used silicone and they have not leaked since. Doesn't take all that much to do a good job

I made new gaskets from gasket stock available from NAPA (not cork). I prefer regular gasket material to RTV where feasible. You might also want to consider adding a <a href="http://www.worldpath.net/~thompson/acb/final%20drives/pan.htm">drain plug</a> while the pan is off.

clean them good, make sure they are float, and a good bead of RTV works good. i prefer the orange stuff that is made for sensors, instead of the red or black.

Me too. Orange RTV silicone.

Rod, the oil pan has a cork gasket, and the engine oil is thinner than the oil in the final drive. What's the problem with a cork gasket?

I didn't mean to imply that there was anything particularly wrong with cork as a gasket material. It's an old time choice that has been used successfully for many years in such service. I indicated that I made mine out of a non-cork material - actually <a href="http://www.agkits.com/victolex-gasket-sheets-1-32-x-18---10-yards-1.aspx">Victolex</a>. I prefer that over cork because I think it is less brittle and easier to work with if you are cutting your own out of sheet material. I also think it is easier to remove at some later time without tearing, like cork sometimes has a tendency to do, especially if a gasket cement had been used.

Thank you for the tip, Rod. That looks like the material to use. I really appreciate the post.

Hey;

I just cut some out of cork, and punched holes with a Blue Point set. No leaks for 3 years. Hope this helps!
