3176B (3NL) Industrial, 3176C (2AW) Industrial, 3196 (1DW) Industrial, 3176B (9WK) Marine, 3176C (6BW) Marine, 3196 (2XR) Marine Engines

Reference: Specifications, 3176B (3NL) Industrial Engines, SENR6462, "Crankshaft". Specifications, 3176B (9WK) Marine Engines, SENR6507, "Crankshaft". Specifications, 3176C And 3196 (1DW1-Up, 2AW1-Up) Industrial Engines, SENR1172, "Crankshaft". Specifications, 3176C And 3196 (2XR1-Up, 6BW1-Up) Marine Engines, RENR1231, "Crankshaft".

The References INCORRECTLY indicate the crankshaft gear should be heated to a maximum temperature of 316°C (601°F) for installation onto the crankshaft. The CORRECT procedure is to heat the crankshaft gear to no more than 210°C (410°F) for no more than 1 hour prior to installation on the crankshaft. Be sure to make note of this information in referenced Specifications modules.
