96700-38 Flywheel End Play Gauge

This flywheel end play gauge from V-Twin is a precision instrument used during bottom-end engine assembly to verify critical tolerances. It screws directly onto the flywheel sprocket shaft, providing a stable platform for a dial indicator to measure lateral movement. While primarily used for Big Twin engine builds, it is also suitable for checking main shaft end play on 45CI models. Equivalent to OEM 96700-38, this tool is vital for ensuring the crankshaft is correctly shimmed within the crankcases, preventing excessive friction or mechanical interference. It is a necessary addition to the toolbox of any mechanic rebuilding vintage or modern Harley-Davidson powerplants to factory standards.
