Description
Cab Air Suspension and Latching System
Three-point suspension means that the cab is attached at two
points in front by a pivot on each rail and latches to an air sus-
pension system on one rail at a rear corner. The system con-
sists of a latching catch bracket, two shock absorbers, an air
cushion and an adjustable height control valve. Air is supplied
via the vehicle air system. Correctly adjusted, the system con-
trols the ride height and relieves stress on the cab pivots.
A cab leveling valve works automatically when a load is applied
(e.g., when someone steps into the cab or pulls down strongly
on a cab entry handle). The flow of system air for adjustment is
audible. The sound can be used to determine the serviceability
of the valve. Adjustment should be complete in two to 10
seconds.
