Expert Installation & Field Note

Drawing from our shop experience specializing in heavy-duty drivetrains since 1985, the N14 and NT855 platforms require strict attention to the 2 locating holes to ensure the crankshaft balance is maintained across the 6-bolt flange. Before seating the 10.12-inch bore, ensure the crankshaft surface is completely free of debris or scoring. We recommend a cross-pattern torque sequence to prevent lateral runout, ensuring the 103-tooth ring gear engages the starter perfectly for reliable ignition cycles in high-demand environments.

CRITICAL: Verify Specifications

Please confirm your original casting number and engine series match these specifications. The 10.12-inch bore size and 103-tooth ring gear are essential for proper fitment and safe vehicle operation.
