Just in time for Maupin!

Who made which? Are they really cheaping out that bad?

When I bought it from a local company it was supposed to be a quality seal to replace the crappy black seal I had that leaked. Hmm, the orange color meant I thought it was a Victor Reinz seal.
Now after removing it with my reading glasses on I see its a "Made in Mexico" seal! Don't use it....as it leaks.
I have now installed a real Victor Reinz orange "B" seal that is thicker and fits nice and tight around the crank and fills the space in the case.
Third time I hope is the charm to not have a leaking rear seal. Yes, the flywheel seal surface is perfect as I picked thru a stack of flywheels to find this one. The old one had a groove worn in it from not changing the oil ever!

yup, the leak seems to be fixed but the real test is the trip down to Maupin. Looks good so far.

I had an orange seal from Mexico...don't know the brand...that leaked in about 6 years and 30K miles.
The new one (last year) is German, but black. I assume it is nitrile or EDPM. No leaks. I hope she holds longer than the old one.

Did the thicker one have a double lip?
Those are great; usually the lips ride on a place other than where the original one did.

not that I saw. Where to buy a rear oil seal with the "double lip"?

[grandfatherjim]

If you look in a catalogue from a company such as Chicago Rawhide, they list them by size. Within the size then they have a few styles, single lip, double lip, etc.
I usually get seals from a local bearing shop; they know the topic.
