Posted: Mon May 24, 2010 4:39 am Post subject: Mag Gasket tear

Over the years I have seen in several different airplanes that when you try to retime the mags, rotating the mag tears the gasket, it leaks and you have to replace it.  Has anyone found a great solution to that problem?  What about coating the gasket during install with fuel lube or antisieze?  Any thoughts?

Yes.  Put a thin coat of Tite Seal on both sides of the gasket.  Tite Seal is available at Aircraft Spruce.  It also works great for any threaded connection.  Tite Seal does not harden.

Hey Gary,

  

 If the other guys have experience with the lube on  the mag gasket, you probably want to go with that.  

  

 Just another idea, on car engines (old Jaguar's are  notorious for gasket failures because over time they move, not break) I've  learned to use the 3M emblem glue (gorilla snot) on the engine side of the  gasket, and RTV (gold, black, red - depending on heat) on the removable side of  the gasket.  A  tap with a chisel breaks the RTV seal, and the timing  cover, mag, whatever should pop right off leaving the gasket intact.  If  replacing the gasket after gluing it on, I use a gasket scraper, then polish it  with the "brillo" pad in the die grinder.

  

 Later, - Lew

I use fuel lube on both sides of the mag gasket and it allows me to move it with tearing.

I would avoid this recommendation. Stick with Titeseal or fuel lube.

You do NOT want to glue the gasket to the accessory case. Good way to

get the aluminum parting surface damaged when you need the gasket

removed. I would not use any RTV where it is exposed to oil like at

this surface. RTV+oil equals a gooey mess that will leak. Totally

different from an auto engine made of cast iron and steel where you

can scrape gaskets off to your hearts content.

 I would suspect that would happen on mags that had been in place for years, and were hard and dry, or were installed with Permetex gasket maker.  I've not had that problem.

 I think either of those items would cut down or eliminate the problem you're seeing.
