anzaniSome engines have no provision for a crankshaft damper on the front, so the next best place is on the rear as part of the flywheel.  

This Anzani engine has an enclosed timing cover on the front which is an integral engine mounting, so we machined a flywheel adaptor and mounted it there instead.  We can supply the damper alone, or design and supply the necessary adaptors as well if required. There are often water pump and dynamo pulleys to incorporate, or in this case a propshaft bearing for a standard Frazer Nash clutch. The damper is a silicone viscous design, which is the fit and forget type.
