Expert Installation & Field Note
Drawing from our shop experience specializing in heavy-duty drivetrains since 1985, the Cummins NT855 platform requires precise alignment of the two locating holes to ensure the crankshaft balance is maintained. We recommend a thorough inspection of the crankshaft flange for any runout before seating the 8.37-inch bore. Verify that your 103-tooth ring gear matches your current starter drive to prevent premature engagement wear and ensure reliable ignition cycles.
Please confirm your original casting number and engine model match these specifications. The 8.37-inch bore size and 103-tooth ring gear are essential for proper fitment and safe vehicle operation.
