Expert Installation & Field Note

Based on our shop experience specializing in heavy-duty drivetrains since 1985, the Caterpillar 3208 series requires precise alignment of the two locating holes to ensure internal balance is maintained. We recommend a thorough inspection of the crankshaft flange for any pitting or wear before seating the 7.12-inch bore. Ensure the 10 mounting bolts are torqued to spec in a star pattern to avoid lateral runout and ensure the 134-tooth ring gear engages the starter perfectly every time.

CRITICAL: Verify Specifications

Please confirm your engine model and original casting number match these specifications. Dimensions like the 7.12-inch bore size and the 10-hole mounting pattern are critical for proper fitment and safe vehicle operation.
