The new seal is only for the 4-cylinder "TRactor motors", ie TR2-4A, plus a
few more like Vanguard, Ferguson Tractor, etc.

As I understand it, the modification adds a lip-type seal in addition to the
original scroll-type seal.  This should solve the problem of leaky rear
seals once and for all; and unlike the lip seal conversions currently on the
market, requires NO modification of the crankshaft!

The seal itself is a high-tech Viton seal, but the overall cost of the
conversion is modest (compared to the currently available conversion),
because the original aluminum scroll seal can be modified to also carry the
new Viton seal.  This can be done even with well-worn original seals, so no
need to buy a new one.

I've promised to gather up some old seals & send to Joe for modification (so
he will have a few available for sale outright instead of exchange), but
unfortunately haven't gotten that done yet.  Real Soon Now.
