Tailshaft seal

[Doug Chahoy]

I've installed a new TH350 in my Elco, I've tried installing a new seal, but so far the 2 I tried seem to big and can't even get them started. I tried what the videos show with no luck, both destroyed. Is there a particular brand/part# that anyone KNOWS fits right?

You did remove the old seal first I hope...

The seals have sealant on the metal and makes them hard to slide in but a few taps with a rubber mallet has always worked for me...

Sorry I can't help but it should be easy to install with a simple tap tap tap. Are you sure that you received the correct seal?

Yes the old ones out. Like I said I ruined 2 different brands.

do you have a vernier to measure the old one vs the new ones

Or, can you get the number off the old seal?

Finally got the 3rd seal in (total PIA) with no drips so far
