during the brake reline service interval. For ser-
vice and lubrication instructions, see
Group 42
of the Columbia® Workshop Manual .
For camshaft brackets with grease fittings, use an
NLGI Grade 1 or Grade 2 multipurpose chassis
grease.
Lubricate the camshaft bushings through the grease
fitting on the camshaft bracket or the spider until new
grease flows from the inboard seal. See
Fig. 6 .
WARNING
If grease leaks out under the camhead, the cam-
shaft bracket grease seal is worn or damaged. See
Group 42 in the
Columbia® Workshop Manual for
grease seal replacement instructions. If this seal
is not replaced, the brake linings could become
contaminated with grease. The stopping distance
of the vehicle will be increased, which could result
in personal injury or property damage.
42–08 Meritor Slack Adjuster
Lubrication
IMPORTANT: Perform MOP 42–10 before lubri-
cating the slack adjusters.
NOTE: If equipped with an extended-
maintenance Q Plus
™
brake system, the slack
adjuster will not have a grease fitting. These
slack adjusters use a special NLGI grade syn-
thetic polyurea grease and do not require lubri-
cation for 3 years or 500,000 miles (804 500
km), whichever comes first. The extended-
maintenance slack adjusters are lubricated dur-
ing the brake reline service interval. For service
and lubrication instructions, see
Group 42 of
the Columbia® Workshop Manual .
For slack adjusters with grease fittings and for oper-
ating temperatures above –40°F (–40°C), use a
NLGI Grade 1 clay-base grease, or a NLGI Grade 1
or 2 lithium-base grease.
For slack adjusters with grease fittings and for oper-
ating temperatures below –40°F (–40°C) and above
–65°F (–54°C), use a NLGI Grade 2 synthetic oil,
clay-base grease.
Lubricate the slack adjuster at the grease fitting until
grease is forced past the pressure-relief capscrew or
past the gear splines around the inboard snap ring.
