Tire Pressure Control systems have either 1, 2 or 3 valve bodies depend-
ing upon the application. The following pages are the rebuild procedures for a single valve
body. Repeat the process for each valve body if required. When working with more than one
valve body ensure all cable harness’s and air lines are returned to the original position when
reassembling the valve bodies. NOTE - One VALVE PACK MAINTENANCE KIT is required
for each valve in the TIREBOSS
TM
system.
Note.. On three zone systems only, the two front
bolts and lock nuts supporting the Valve Control Module
Bracket will have to be removed in order to tilt bracket to
allow room for valve assembly removal.
