Triumph TR6 Clutch Assembly
Two different manufacturers supplied clutch assemblies for production line fitment to the TR6s. Debate still rages on the pros and cons to be had from using either a Borg and Beck or a Laycock clutch; the only indisputable fact is that they are completely interchangeable if fitted as functional sets of cover and plate.
One limiting factor must be considered when changing allegiances from one manufacturer to the other: the Borg And Beck cover assembly requires longer screws to attach it to the flywheel than those used to fit the Laycock cover (this is because the mounting flange on the Laycock cover is thinner than that on the Borg And Beck item). On the other hand, the length of the screw thread must not exceed 3/4" (for the Borg and Beck clutch) or 5/8" (for the Laycock clutch), otherwise the screws may bottom in the tapped hole in the flywheel, leaving the clutch cover loose.
