42–07 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform MOP 42-05 before lubri-
cating the camshaft brackets.
NOTE: If equipped with an extended-
maintenance Q Plus
™
brake system, the cam-
shaft bracket will not have a grease fitting.
These camshafts use a special NLGI grade syn-
thetic polyurea grease, and do not require lubri-
cation for 3 years or 500,000 miles (800 000
km), whichever comes first. Extended-
maintenance camshaft bushings are lubricated
during the brake reline service interval. For ser-
vice and lubrication instructions, see
Group 42
of the 108SD and 114SD 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. 13 .
WARNING
If grease leaks out under the camhead, the cam-
shaft bracket grease seal is worn or damaged. See
Group 42 of the
108SD and 114SD 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 dam-
age.
