Usage:

OFF-HIGHWAY TRUCKS793C (4GZ1-Up) OFF-HIGHWAY TRUCKS

Problem:

Some 793C Off-Highway Trucks may have been shipped with 106-3722 Suspension Cylinder Groups (1) that have 1D-4588 Bolts (2) that are not fully tightened. If the 1D-4588 Bolts (2) are not fully tightened, the cylinder will leak and it will not maintain a pre-charge pressure.

Solution:

Inspect the 106-3722 Suspension Cylinder Groups (1) to ensure that all nineteen EXPOSED 1D-4588 Bolts (2) are tightened to a torque of 215 ± 40 N·m (160 ±30 lb ft).

------ WARNING! ------

Do not remove the four 1A-5405 Bolts (3) and the four 5P-8247 Washers (4) that secure the two 4T-4769 Covers (5). Oil may be forced out due to the nitrogen pressure of the cylinder.
