"New Lip-Type Seal Requires No Modification to the Crankshaft
or Engine Block"
The quest continues to stop oil leaks
around the rear of the crankshaft! The new seal
is a very high quality Viton seal fitted to a
modified stock seal casting. Viton is way
beyond Neoprene, and it is used in expensive
applications where long life is required. This
product was developed by a Triumph racer in
Germany. He is having the Viton seal
manufactured there, and Joe Alexander of ARE
is importing them and adapting stock rear seals
to take the new lip seal.
Other lip seal conversions require
machining of the crankshaft and an expensive
new seal casting. Once you have modified
your crankshaft, it cannot take the stock seal
again. The ARE seal kit listed here fits your
stock crank and block. This avoids the cost of machining and the chance that the
crankshaft might be ruined in the process. In addition, you have the choice to go back
to the stock seal again at some future time if you wish.
The original workshop manuals provide instructions for making a tool for centering
the rear engine seal. Regrettably, the dimensions provided for this tool are incorrect!
Joe Alexander worked with Kas Kastner to correct the dimensions, and the centering
tools provided in the kits or available for purchase separately are correct. Mr. Kastner
will discuss the new seal and the centering tool in his forthcoming book (No. 4) which
is being published now, and TRF will list as soon as it comes into stock.
I regret that, for the moment, the seal kit will be non-discountable, as there is
virtually no profit to ARE or to TRF...
