IMHO if you're doing a complete ground-up rebuild on almost any Triumph, a
professional balancing
and re-jointing exercise on the propellor (drive) shaft will be money well
spent. Propshaft
vibration on Triumphs was a major headache on all models from Herald and its
later derivatives
onwards. Same went for TR and big saloons as well. The most common cause was
inadequate spot welding
of the balance weight and it flew of with centrifugal force. I had mine redone
about four years ago
and went to the additional precaution of fitting two nylon cable ties around
either end of the
balance weight......... just in case:)
