HDI’s Adjustable Cam Gears

Check out these trick new adjustable straight-tooth cam gear sets, available thanks to Steve Wilkerson of HDI Products. The black oxide, 28-32 RcC-hardened, 5120 steel gears offer four precision bolt patterns to give 0, 2, 3, 4, or 6° advanced or retard options. Patterns are stamped A, B, C, and D; slot in cam gear points to letter of given degree options marked on the teeth (Diagram shows 2° advanced). Precision 14mm hex-head Grade 8 cam bolts have a shoulder to drive the gear, eliminating driving gears with threads. Also, the crank gear has a built-in spacer, and these gear sets are available in stock and .100-drop cam sizes, plus shipping.
For more information about this precision adjustable setup, contact Steve Wilkerson at HDI, PO Box 1671, Gresham, OR 97030, or purchase them direct from Steve’s website,
