Unlike some earlier models, this unit has 0 locating holes; therefore, centering the flywheel on the crankshaft flange is critical during the initial bolt-up. Always verify that your starter drive is compatible with the 138-tooth ring gear to ensure reliable ignition cycles. CRITICAL: Verify Specifications Please confirm your original casting number and engine series match these specifications. The 12-hole mounting configuration and 7.25-inch bore size are essential for proper fitment and safe operation.
