PROBLEM

An incorrect torque value could potentially have been applied to the 0L-1328 Bolt, that mounts the torque converter yoke, on certain 789D, 793D, and 793F Large Off-Highway Trucks. If this bolt has not been tightened to the correct tightening specification, there is the potential for catastrophic failure of the bolted joint during unit operation, which may cause significant collateral damage to the surrounding area.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 23% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.


ACTION REQUIRED

The assembly torque for the 0L-1328 Bolt is 430 +/- 50 N.m (317 +/- 37 lb ft). Set a torque wrench to 380 +/- 10 N.m (280 +/- 7 lb ft) and check the bolted joint. If the bolt fails static torque inspection, replace the bolt. If the machine is still new (not released to customer and in operation), a failed bolt does not require replacement, the existing bolt will need to be tightened to the proper assembly torque. Refer to Image 1. If, because of local tooling design or work practices, the yoke bolts have to be removed to perform the inspection, then replace those (4) bolts and claim the extra labor according to the Service Claim Allowance.
