Fig. 4, Camshaft Bracket Lubrication
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
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 for
Haldex slack adjusters. Dana Spicer Low Lube slack
adjusters should be lubricated with SHC 460 syn-
thetic 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.

1. Grease Fitting
Fig. 5, Dana Spicer Automatic Slack Adjuster
Lubricate a Gunite automatic slack adjuster at the
grease fitting until grease appears on the camshaft,
or flows from the grease relief. See
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
42–07 Meritor Camshaft
Bracket Lubrication
IMPORTANT: Perform
cating the camshaft bracket.
NOTE: If equipped with an extended-
maintenance Q Plus ™
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
