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.

bleed adaptor on the reservoir.

transparent drain hose on the bleed valve of the
slave cylinder.

mounted in a horizontal position. If it isn’t, re-
move the slave cylinder and hold it in a horizon-
tal position to completely purge all air from the
cylinder.
5. Pressurize the reservoir, filling the system. Open
the bleed valve on the bleed tank.
NOTE: A pressure bleeder hose (J-29532) and
a bleeder adaptor (J-35798) for the fluid reser-

Tools and may be used to complete the follow-
ing procedure. To order these parts, call Kent-
