WARNING
Clutch hydraulic fluid (DOT 3 brake fluid) is haz-
ardous. It may be a skin irritant and can cause
blindness if it gets in your eyes. Always wear
safety glasses when handling clutch hydraulic
fluid or bleeding hydraulic lines. If you get clutch
hydraulic fluid on your skin, wash it off as soon
as possible.
9. Check for signs of leakage at the clutch slave
cylinder.
CAUTION
Do not spill clutch hydraulic fluid (DOT 3 brake
fluid) on the cab paint. Clean it off immediately if
any is spilled. DOT 3 brake fluid can damage
paint.
9.1 If leakage is found on the slave cylinder
body, check the fittings and hose for dam-
age.
9.2 If leakage is found on the piston seals,
replace the slave cylinder and bleed the
clutch hydraulic system. For detailed in-
structions, see
Group 25 .
9.3 If the slave cylinder fittings and/or the
hose are damaged, replace them.
9.4 Check the torque on the slave cylinder
mounting capscrews. Tighten them 15
lbf·ft (20 N·m).
9.5 If any leakage of clutch hydraulic fluid is
found, check the fluid level in the reser-
voir, and add fluid if needed. For detailed
procedures, see
Group 25 .
NOTE: There are two cover plates on the coun-
tershaft, one at the front and one at the rear.
10. Check for signs of leakage at the clutch bell
housing. If leakage is found, check the radial
seal on the input shaft, the front cover plate on
the countershaft (inside the clutch bell housing),
and the rear radial seal on the crankshaft.
10.1 If the radial seal on the input shaft is
leaking, replace the radial seal. For pro-
cedures, see Section 26.02, Subject
120, of the
Acterra ® Workshop Manual.
10.2 If the cover plate on the countershaft is
leaking, replace the cover plate. Apply
liquid gasket (Loctite 518) to the new
cover plate when installing it.
10.3 If the rear radial seal on the engine
crankshaft is leaking, replace the rear ra-
dial seal. For procedures, see the engine
manufacturer’s manual.
11. Remove the chocks from the tires.
