There is a red sealant the auto atores are handling now that is even
approved by faa (so I waS told) it acts like an anaerobic sealer with
silicone rubber in it. forgot the number--in a red tube quite a bit
higher than the other types, but well worth it. Jerry

After splitting the engine cases, what is recommended for resealing

Thanks!

Thanks for the reply Richard.

I think I should have provided a few more details- we were in a rush
earlier.

I split the cases on a military aircraft gearbox for inspection. It appears
to be sealed with what we used to call 8802 (I think the proper title is
MIL-S-8802 sealant). This gearbox is for a non-aircraft project and is
exposed to high temperatures as it's nestled in the cheeks of a turbine
exhaust duct.

The lube oil supposedly reaches 180F but I think the housing may see 300F. I
think the case reaches pressures of 25 psi. The lube oil passages reach 120
psi.

I tried to locate 8802 or a substitute, without success. If you are not
familiar with 8802, when set it is like a grey colored 3M 5200 sealant. It's
a little tougher than Blue RTV.

What products should I be looking at to reseal this gearcase?

Thanks in advance.
