(6HK527-Up),
789B (7EK393-Up),
793B (1HL411-Up) Off-Highway Trucks;
994 (9YF165-Up) Wheel Loaders;
5230 (7LL38-Up) ExcavatorsA process to improve the torque value consistency on the air starting motor is implemented in the above machines powered by 3500 engines.
The following torque pattern is the correct procedure to use when tightening the air starting motor body with 5N-8427 Bolts:
* Tighten all four bolts in a crossing pattern to 68 N m (50 lb ft).* One at a time in the same crossing pattern, loosen each bolt one half turn.* Re-tighten the bolts in the crossing pattern to 74.8 .06 N m (55 1.00 lb ft).The above procedure has been implemented, effective with the above serial numbers.
