WARNING
•
Before performing any work on the spring brake system, chock the wheels front and rear to prevent
semitrailer movement. Failure to follow this warning may result in injury or death to personnel.
•
All brake chambers must be caged before working on the brake system to prevent serious injury to
personnel and damage to equipment.
•
The axle must be firmly supported to prevent shifting of the semitrailer. Shifting may cause serious
injury to personnel and damage to equipment.
•
Clean and check all S-camshaft brake components for wear and damage. Replace worn or damaged
parts. At Triennial Service replace all O-rings, bushings, retainers, snap rings, lockwashers, and
brackets on each axle end. Failure to comply could cause injury to personnel and damage to
equipment.
NOTE
•
There are four brake S-camshafts (two left and two right) and they are removed and installed the
same way. Right and left does not mean left and/or right side. Left or right S-camshaft is specific to
S-camshaft rotation in operation (see WP 0107). This procedure covers one brake S-camshaft.
•
S-camshafts and related parts are to be lubricated in accordance with WP 0067.
