IMPORTANT: This maintenance operation per-
tains only to vehicles equipped with mechanical
(not hydraulic) linkages.
The clutch release cross-shaft is equipped with two
grease fittings in the transmission clutch housing.

25–03 Clutch Hydraulic Fluid
Level Checking
WARNING
2015 Freightliner M2 For Sale
Use only approved clutch hydraulic fluid (DOT 4
brake fluid) in the clutch hydraulic system. Do not
mix different types of brake fluid. The wrong fluid
will damage the rubber parts of the system, caus-
ing loss of clutch function and the risk of serious
personal injury.
CAUTION
Do not allow the fluid level in the reservoir to go
below the MIN line. If too much air enters, the hy-
draulic system will not operate correctly, and the
clutch could be damaged.
If the fluid level is below the MIN line, fill the reser-
voir with DOT 4 brake fluid until the level reaches the
MAX line. See
25–04 Clutch Hydraulic Fluid
Changing
Replace the clutch hydraulic fluid every two years to
ensure clutch function is reliable and correct. Use the
