Engine #6 - Compensating Sprocket
Life's a bitch... Thank God there's Harleys...
On this page you will find some pictures that T made during installation of the compensating sprocket in our 1973 Harley Sportster Ironhead engine. The Harley compensating sprocket is attached to the flywheel sprocket shaft and acts like a shock absorber between the engine and the transmission. It is installed after the primary chain has been installed.
Compensating Sprocket Preparations
We first cleaned all individual parts of the compensation sprocket assembly in our parts washer. Not only to degrease the parts, but to make sure that the parts did not carry any tiny metal particles that could cause havoc later on.
