Clean, Inspect, and Replace-Transmission, Transfer Case, and Axle Breathers

IMPORTANT: DO NOT spray steam, water or cleaning solution directly at breathers. Spray could be forced into housings.

NOTE: Breathers should be checked daily in adverse working conditions. The amount of dust and dirt encountered will determine the frequency of breather cleaning.

The cab must be tilted to access the transmission breather cap and front axle breather.

1. Clean dirt, dust, and debris from each breather (1-5) and from surrounding areas.

IMPORTANT: DO NOT crush or damage breathers during removal. Foreign matter may enter housings.

2. Inspect each breather for clogging, damage, and proper installation. If necessary, remove clogged breather(s) from machine and clean with water. Dry thoroughly before reinstalling. Replace any breather that appears damaged or cannot be unclogged. Tighten to specification.
