Re: Cork rear main seal opinions? Wasn't aware of a two piece style seal, interesting.

Re: Cork rear main seal opinions? There are two different groove widths and the difference isn't very much but try cutting composite cork to get a too wide one to fit and then you can see why they provide both widths. They need to fit tight in the groove so only one is needed.

Re: Cork rear main seal opinions? This is a seal for the rear main bearing with slinger removed. Not the bearing housing to oil pan cork

Re: Cork rear main seal opinions? They seem to work great for a few hundred miles then they have the tendency to leak. And some times pretty bad. We just had one reversed. Welded the slinger back on the shaft and put it back like original. Lot of work but fixed the leak.

Those 2-piece cork seals were available from Snyder's for a very short time. If your diameter for the seal rubbing surface is between 2.090 and 2.150 inches, you can use the 1-piece modern radio lip seal that slips over the flywheel mounting flange. Look for Bratton's #8970, Snyder's A-6336, Bert's A-6335-M, and others. |
Re: Cork rear main seal opinions? Just tried installing a 1 piece rear main cork seal and it was too tight to fit into the groove. Will let the cork soak in oil overnight and try again tomorrow.

Re: Cork rear main seal opinions? Thnx. I figured like most pack type seals once they wear a little they start to leak

Re: Cork rear main seal opinions? If cork worked well for a rotational seal, Ford would have used it. In later years, they went back to the rope type seals. Modern fluorocarbon and fluorosilicone lip seals eventually showed up due to successful use in the aerospace industry.
The big oil slinger ring was hard to beat in the technology of the day. It required a drain tube that was protected from crankcase pressure so that's what they used and it does work as long as all the components involved are in serviceable condition. |
