This is the E-Z Bore exclusive PTO degree wheel hub and mounting hardware. We also sell the degree wheel hub assemblies, which include a pre-mounted hub.

Small engine degree wheel hub fits Comp Cams and Mr. Gasket degree wheels with a 1" center bore. The E-Z Bore degree wheel hub provides accurate mounting of most automotive degree wheels with large center bores. You can easily convert your automotive degree wheel to accurately and quickly mount to any 3/4" diameter performance small engine crankshaft. NOTE: Degree wheel will need to be drilled to mount onto hub.

Most sanctioning bodies for 4-cycle karting require stock camshaft profile checks as post-race technical inspections. These hubs provide an accurate way for machine shops, professional and ameteur engine builders to setup a degree wheel to accurately check camshafts, as well as ignition timing.

NOTE: Sales price is for one hub only. Photograph to left shows machining detail of front and back sides of hub.
