25–02 Eaton Fuller Clutch
Release Cross-Shaft
Lubrication
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.

lubricate with multipurpose chassis grease.
25–03 Fluid Level Check,
Hydraulic Clutch Control
WARNING
Use only approved fluid (DOT 4 brake fluid) in the
hydraulic clutch control system. Do not mix differ-
ent types of brake fluid. The wrong fluid will dam-
age the rubber parts of the system, causing loss
of clutch function and the risk of serious personal
injury.
NOTICE
Do not allow the fluid level in the reservoir to go
below the MIN line. If air enters the system, the
hydraulic 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 new DOT 4 brake fluid from a tightly sealed
container until the level reaches the MAX line. See
Fig. 4.
25–04 Fluid Change, Hydraulic
Clutch Control
Replace the hydraulic clutch control fluid to ensure
clutch function is reliable and correct. It can be
changed by pressure bleeding or manual bleeding.
Pressure bleeding can be done by one person and
manual bleeding requires two.
