Triumph Racing tappet blocks
These USA made tappet blocks are an excellent choice to replace broken or worn originals, and will work in most 500, 650, and 750 cylinders. They have been designed to accept higher cam lift without modification. Available in cast iron and C674 bronze for both Pre Unit and Unit Construction models.
Based on the exhaust tappet block from 1969-1982, Triumph part number 70-9353, these are drilled for a tappet oil feed. However if the pressurized oil feed is not used there are no problems.
Bronze tappet blocks are an excellent replacement for quick wearing aluminum tappet blocks used in the alloy 500cc pre unit engines.
