Installation is rated at approximately 7 hours by a professional technician. Because the transmission and transfer case must be completely removed, a commercial vehicle lift and transmission jack are required. — • Estimated Install Time: Approximately 7 hours of shop labor. • Required Equipment: Heavy-duty transmission jack capable of supporting the large-case Aisin AS69RC (dry weight exceeds 350 lbs), vehicle lift or tall jack stands, Cummins barring tool, and calibrated foot-pound torque wrenches. • Prerequisites: Removal of the front and rear driveshafts, transfer case (on 4x4 models), crossmember, starter motor, cooler lines, torque converter bolts, and the bellhousing-to-engine bolts. • Bolt Replacement: Inspect factory flexplate-to-crankshaft bolts for stretch or wear, and always torque all crankshaft and torque converter fasteners in a multi-stage star pattern to factory Ram/Cummins OEM torque specifications. • Clean Mounting Surface: Ensure the 6.7L Cummins crankshaft mounting flange is thoroughly cleaned of rust, debris, and old threadlocker prior to setting the flexplate in place.
