42–04 Slack Adjuster
Lubricating
IMPORTANT: Perform MOP 42-15 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.
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. 3 . 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.
Gunite automatic slack adjusters are produced with-
out 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 ap-
pears on the camshaft.
Meritor
NOTE: If equipped with an extended mainte-
nance Q Plus
™ brake system, the slack adjuster
will not have a grease fitting. These slack ad-
justers use a special NLGI Grade synthetic
polyurea grease and do not require lubrication
for 3 years or 500,000 miles (800 000 km),
whichever comes first. Extended maintenance
slack adjusters should be lubricated during
brake reline service. For service and lubrication
instructions, see
Group 42 of the Saf-T-Liner C2
School Bus Workshop Manual .
For slack adjusters with grease fittings and for oper-
ating temperatures above –40°F (–40°C), use an
NLGI Grade 1 clay-base grease or an NLGI Grade 1
and 2 lithium-base grease.
For slack adjusters with grease fittings, and for oper-
ating temperatures below –40°F (–40°C) and above
–65°F (–54°C), use a NLGI Grade 2 synthetic oil or a
clay-base grease.
Lubricate the slack adjuster at the grease fitting until
grease is forced past the pressure-relief capscrew or
past the gear splines around the inboard snap ring.
