These seals are sold in the U.S. by British Frame and Engine ($125) and by
Moss (TR3 - 4 catalog page 71, $129.95) and maybe others of which I'm
unaware. There appears to be two manufacturers, both in Great Britain, and
one of the manufacturers told me that the Moss kit is a knockoff of the
Both kits use the same split seal insert.
The dimension to which the crank is to be turned was 2.500 for several
years. After I had several problems with them, and discovered that the
neoprene seal itself sometimes had an I.D. of 2.500" resulting in no lip
seal tension, the manufacturer of the kit changed the crank dimension to
2.520. That should help. There are other tricks that can be employed in
assembling them that may also help make them seal 100%.
I have measured every dimension on the aluminum housings from both sources
and I use the one from BFE.
