CAUTION
Do not use moly-disulfide-loaded grease or oil.
Both the life and reliability of the slack adjuster
will be reduced if this type of grease is used.
Lubricate the automatic slack adjuster at the grease
fitting (see Fig. 5). Use standard chassis lubricant.
Gunite
For operating temperatures of –20°F (–29°C) and
higher, use Texaco Multifak EP-2 or Mobil Grease
No. 77.
For operating temperatures between –20°F (–29°C)
and –40°F (–40°C), use Lubriplate Aero grease.
Lubricate a Gunite automatic slack adjuster at the
grease fitting (see Fig. 6) until grease appears on
the camshaft, or flows from the grease-relief.
The newest Gunite automatic slack adjusters are
produced without a grease-relief. During lubrication
with a grease gun, lubricant is forced through the
drilled worm wheel onto the camshaft. Lubricate the
automatic slack adjuster at the grease fitting (see
Fig. 6) until grease appears on the camshaft.
42–07 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform MOP 42–11 before lubri-
cating the camshaft bracket.
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. The extended-
maintenance camshaft bushings are lubricated
during the brake reline service interval. For ser-
vice and lubrication instructions, see Group 42
of the
Century Class Trucks Workshop Manual
.
For camshaft brackets with grease fittings, use an
NLGI Grade 1 or Grade 2 multipurpose chassis
grease.
