Always replace cam bearings with the ones provided in this kit or another source.
2- Installing the Cam Gear Drive
Check pinion shaft runout. Indicate end of pinion shaft at cam support plate bushing surface and rotate engine; reading must be .003” or
less total indicated reading (TIR). If reading is greater than .003” TIR the crankshaft must be repaired or replaced to correct excess runout
before installing gear drive cams. Failure to correct excess runout may lead to engine damage not covered under S&S warranty.
