for a Haldex slack adjuster. Use standard chassis
lubricant for Haldex slack adjusters.
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 until grease appears on the camshaft,
or flows from the grease relief. See
Fig. 6 .
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 until
grease appears on the camshaft.
42–06 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform MOP 42-15 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 Business Class® M2 Workshop Manual .
For camshaft brackets with grease fittings, use an
NLGI Grade 1 or Grade 2 multipurpose chassis
grease.
