There are some 492-8877 Shipping Skids that were not adequately welded between the engine mount and the engine stand base for Reman engines built between 01 March 2016and 05 April 2016.Table 1 contains the affected engine serial number ranges for this problem.

Inspect the engine shipping stands for the engine serial numbers listed in Table 1.Note: Each engine stand in the suspected range has a stand serial number. Engine stands without a serial number or not listed in Table 2 are acceptable for use.

If the engine stand serial number is found in Table 2, inspect the 4 weld locations shown in Illustration 3. Inspect the welds where engine clamp (3) meets engine stand base (4).
If there is a 25.4 mm (1 in) block as a spacer welded between the engine stand base and the engine clamps, the engine stand is unacceptable.
The engine stand should be removed from use due to inadequate weld penetration.
Use the procedure that follows for any engine stand that has to be removed from service for inadequate weld penetration.
Remove the engine from the suspect engine stand.
Remove the paint and prepare weldment around the joint between the engine clamp to engine stand base.
Fully weld the engine clamp to engine stand base around all four sides.
If a 6.35 mm (0.25 in) plate is present between the engine stand base and 1 in block, fully weld the plate on both sides.

Example of a fully welded engine clamp on 4 sides
Reinstall the engine onto the stand and torque the engine stand clamps to 105 20 N m (77 15 lb ft).
