42–06 Dana Spicer, Haldex,
and Gunite Slack
Adjuster Lubrication
IMPORTANT: Perform MOP 42–10 before lubri-
cating the slack adjusters.
Automatic slack adjusters that have a grease fitting,
must be lubricated periodically to ensure proper
brake operation.
WARNING
Failure to lubricate slack adjusters could lead to
dragging brakes or a brake failure, resulting in
property damage, personal injury, or death.
Dana Spicer and Haldex
NOTICE
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. 7 . 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 until grease appears on the camshaft,
or flows from the grease-relief. See
Fig. 8 .
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. See
Fig. 8 .
42–07 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform MOP 42–10 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.
