Crankshaft Seal Sealant
 

What is the proper sealant to use during installation of the crankshaft seal for a TSIO-360CB?

My overhaul manual is not helpful. A Continental Service Bulletin is only marginally more helpful, stating only "Apply a thin coat of Permatex to the O.D. of the seal." Great, but Permatex has a bunch of products.

I did a search here for 'proper sealant to use on crankshaft seal' and got:

'The search term you specified (for) is under the minimum word length (4) and therefore will not be found.'

I admit, it's been a while since I learned how to count, but I'm pretty sure that's more than four words. I get that reply a lot.

A search of the Web shows people using Titeseal and Dow 717. Some people say use a non-hardening sealant some say use a hardening sealant. I just want to use the proper sealant and not experiment.

Sorry, I don't have an answer to your question, but do have a search tip. The best way I've found to search SOAPA is by using Google with a "site" filter. Prefix your search with "site:www.337skymaster.com" then add the search words.

Ex: "site:www.337skymaster.com crankshaft seal"

Downside of this method is the index seems to be about 6 months behind.

Thanks for the tip. No luck this time...maybe the subject hasn't been discussed before.

I’ve used pliobond it’s a contact cement like 1300L or yellow glue probably get a can from spruce
The permatex is the aviation form-a-gasket or it use to be #2

Thanks, Kim. The Aviation #2 sounds pretty official, and even Wally World carries it.

The Continental M-0 repair manual has all the info on procedure and sealants to use, on the road and from memory…

Clean bore well with MEK, there is a spray primer that is applied, then the purple case half sealant goes on the bore, then the permatex brown liquid on the seal and install.

When I can I will get the actual numbers of the items.

Thanks, Dan.

One sticking point is that the person who installed the seal retainer plates, 90 degrees off from what the parts diagram shows, did so when the sealant was still wet. I don't think they're going to come off without being bent. Good thing new plates are so cheap. Less than $20 each! :0(

I am still traveling on the road, the plan is to be back home this eve at our airport, I can get the info tonight and will supply it.

Dan,

I found the M-0 Standard Practice Maintenance Manual, thanks for the tip.
