Cam shaft seal
For years I fitted the seals supplied by the vendors and we all know that the have too smaller OD and need to be glued/sealed in place.
So the million dollar question is, why have we been putting up with them when I simply walked into our local bearing store and bought the right size to fit in??

Re: Cam shaft seal
That's easy...most of us don't have a "local bearing store". And if we did the kids running the place wouldn't know how to locate the part.

Re: Cam shaft seal
So, what is the number of the seal with the proper OD?

Re: Cam shaft seal
Frank, that's the standard size, 1.0" internal 1.5" external, 1/4" wide. I have bought the same size from CBC. Sometimes they fit, sometimes they don"t. My guess is the timing covers vary. After all, a lump of felt will fit any size hole.

Re: Cam shaft seal
Kerry, Have you tried your new seal in your timing cover yet? Was it a good “press fit”? If it was, then that seal is oversize, or the hole in your cover is undersize...

Re: Cam shaft seal
Yep, a good tight fit, tried another in several covers on the shelf 1916 and up, same thing, I've never had one from the vendors be any more than a fall out fit and need to be glued in and I've fitted many on every rebuild over the years.

Re: Cam shaft seal
Its interesting that I can't seem to find that seal number within the US easily, and that it doesn't seem to cross directly to CR9878 or SKF 471224.....even though they all "appear" to be the same size.
I agree with the pain in the A deal of having to make the other seal work, but at least for me, mine has been trouble free so far from the install. I think I remember bending outward the metal on the seal some to take up space, before siliconing it into place.
Edit: Digging around a little (because this topic has come up time to time) I just saw another post from April, where it was suggested that a SKF 9853 seal be used for the camshaft. And upon checking on it shows that it indeed has a slightly bigger outer diameter of 1.514 that fits a bore of 1.51. Maybe that is all the difference needed? I don't have any covers near me currently to check.

Re: Cam shaft seal
I remember that when Milt Webb first proposed using a neoprene seal on the camshaft, he mentioned that it needed a little squeeze between two bits of wood in the vice to swell the outer circumference. I usually do that and add a little black silicone seal. It may not be perfect but it’s worked for me for close to forty years.
