Service bulletin SIL 785

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 has discovered that affected units may not have a PTO request wire properly connected to the transmission control module. Without this wire installed, the chassis may not produce the hydraulic pressure required for proper PTO clutch pack engagement. Altec requires the unit to be inspected for the PTO request wire no later than the next periodic maintenance interval or 90 days from the receipt of the SIL, whichever comes first. If the inspection procedure in the SIL confirms that the PTO request wire is missing, order the PTO Request Wire Kit and install the kit no later than 6 months from the receipt of this SIL.
