This top quality top-end gasket set features all of the gaskets, pushrod tube seals, o-rings, and copper washers to seal up the top end of the engine for the 1971 and 1972 B-range Triumph 650 models. The copper head gasket is not included in this set and is sold separately under part number 70-4547.
Sourced from Cov-Seal in the US, these gaskets are precision cut to the correct dimensions for optimal fitment and sealing properties. Included in the set is a cylinder base gasket, rocker box gaskets, rocker inspection cap washers and gaskets, rocker spindle o-rings and copper washers, guide block o-rings, manifold gaskets, and the correct pushrod tube seals and o-rings.
Cov-Seal gaskets are recommended to be fitted dry, without sealant or gasket cement, as the Buna-N gasket material binding agent can be softened by the chemicals that some sealants contain.
The mating surfaces must be free of old gasket material and sealant, and polished flat prior to fitting the gaskets. Any divots occurring on mating surfaces should be filled in, either by welding, or with epoxy, then filed flat to eliminate any possible oil paths. If the cylinder head has been milled, a thicker head gasket may be required to achieve the proper “crush” of the pushrod tube seals.
