Service bulletin SIL 753

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec discovered that the torque requirement for the inner race rotation bearing bolts for the LS60 was incorrect on one of the pages in the Maintenance Manual. The correct torque requirement is 300 foot-pounds (407 N.m). In the two manuals included with the affected units, the torque requirement is incorrectly stated at 365 foot-pounds (496 N.m) on page 24. Two replacement pages stating the correct torque value are included with this SIL. Altec requires that the original page 24 be removed from each of the two maintenance manuals in the three ring binders and the replacement page be inserted in its place. This replacement should be completed no later than 30 days from receipt of this SIL. If additional maintenance manuals are required for multiple units, two-sided copies can be made and used for replacement.
