Again, thanks! | | | | Joined: Jul 2011 Posts: 257 Shop Shark | | Shop Shark Joined: Jul 2011 Posts: 257 | So I'm getting ready to install the flywheel/clutch assy on my 235. I was reading through the manual and it said something about applying Goodyear PliaBond #3 between Flange and Flywheel surfaces. I have looked through several threads on Stovebolt.com and did not see anything about applying any kind of sealer. Can I use Permatex Gasket Sealer or do I even need to do this? | | | | | Joined: Sep 2010 Posts: 166 Shop Shark | | Shop Shark Joined: Sep 2010 Posts: 166 | Never heard of doing such a thing! I didn't use anything on mine, never have. Just loctite on the bolt threads.

I then looked at the 1949-54 Passenger Car Shop Manual, and it does not say anything about using any sealant. I have not looked at any other manuals yet to what else is said. I've never used any sealant in dozens of 235s and 261s, some of which were used for racing. Has anyone ever used the Pliabond or equivalent?

However, the bolts holes in the crank are open drilled thru and will wick oil past the bolt threads. I use a SMALL amount of locktite pipe sealant w/ teflon (like teflon tape in a tube). Locktite thread sealant works good most of the time but I trust the pipe sealant more. Don't use any type of RTV on the threads.

The manuals were written by technical writers with a degree in literature not mechanics or engineers. I firmly believe that some procedures are misinterpreted by them and the mistakes are not caught by the time the page went to press. I also believe that they were addressing the sealing of the bolts.
Good old automotive sealer, Permatex #2 or 3H which is brush applied has fit the bill for nearly a century. And it's worked for me for a little more that half that amount of time to seal oil, water and gasoline into or out of where you want it to stay.

I'll pick up some Permatex #2 and be done with it. Thanks again | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Actually I should have said Permatex 3H for this application, same thing just in a more liquified form. http://www.pbase.com/dennygraham/image/140573646/large Denny G

It's a Permatex Gasket Sealer, it comes in the same style bottle, has that redish color and looks to have the same consistency as your photo. Will that be ok to use? | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | What's the number????? Sounds like 98H the high tack sealer. Sure that would work, it's non hardening, goot from -65°to 500° and isn't desolved by anything known to man. Go for it.
