I haven't seen anyone answer Dan's question directly yet. The fact is, the
TR3 and TR4 don't have any damper at all. There's a 6" steel "fan extension"
that looks a little like a dumbbell, to which the fan bolts. The pulley bolts
to the other end and the crankshaft dog bolt attaches the whole thing directly
to the crankshaft. I don't frankly see how the fan could make much
difference, although there are some small "balancing" pieces you're supposed
to use to balance the fan. I recently found an aluminum fan extension cast
the same as the original steel piece, but without any holes for fan attachment
at all. It appears to be a Triumph racing product and was apparently designed
to be used without a fan.
