Service bulletin TSB 436

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

Newmar Corp. has decided some 2016 motorhomes equipped with a HWH Hydraulic Full Wall Slideout may have been shipped with low fluid level in HWH hydraulic system. This TSB only applies to units with a hydraulic Slideout system built prior to 9/14/2015. If there is not enough fluid in the reservoir tank; the HWH slide system (when activated) will draw in air with the fluid and cause uneven pressure on the HWH chain/bracket while opening and closing the slide. This could cause the chain/bracket to loosen over time.
