4. Label or otherwise mark the hydraulic hoses in

relation to the slave cylinder being removed.

Disconnect and cap the hydraulic hoses and slave

cylinder fittings.

5. Securely support the slave cylinder. Remove the

nuts, hex-head capscrews and cylinder pins

securing the slave cylinder to the vehicle frame and

outer boom.

6. With the help of at least one assistant, remove the

slave cylinder from the vehicle. Wipe up any

hydraulic fluid spillage in, on, near and around the

vehicle.

b. Slave Cylinder Disassembly

Note: An additional o-ring may be included at the base

of the cylinder rod. This additional o-ring may be discarded,

as it served only in a temporarily protective role.

1. Clean the slave cylinder (Fig. 8-69, 1) with a suitable

cleaner before inspection. Remove all dirt, debris

and grease from the cylinder.

IMPORTANT: Avoid using excess force when clamping

the cylinder in a vise. Apply only enough force to hold the

cylinder securely. Excessive force can damage the cylinder

tube (Fig. 8-69, 2).

2. Place the slave cylinder in a soft-jawed vise or other

acceptable holding equipment if possible.

3. Extend the rod (Fig. 8-69, 3) to allow access to the

base of the cylinder.

IMPORTANT: Protect the finish on the rod at all times.

Damage to the surface of the rod can cause seal failure.

4. Using a pin spanner wrench, unscrew the head

gland (Fig. 8-69, 4) from the tube (2). The head

gland was originally torqued at 250-300 lb-ft

(339-407 Nm), so a considerable amount of force is

required to remove it. Carefully slide the head gland

down along the rod toward the eyelet end, away from

the cylinder tube (2).

IMPORTANT: When sliding the rod and piston assembly

into the tube, prevent the threaded end of the tube from

damaging the piston (Fig. 8-69, 5). Keep the rod centered

within the tube to help prevent binding.

5. Carefully pull the rod (Fig. 8-69, 3) with all

attachments straight out of the tube (2).

MA7080

Torque to 250-300 lb-ft

(339-407 Nm)

Apply Loctite #271 to

threads and torque to

675-750 lb-ft

(915-1.017 Nm)

WARNING: Escaping hydraulic fluid

under pressure can penetrate the skin, causing

death or serious injury. Relieve hydraulic pressure

before servicing any hydraulic component.
