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).

under pressure can penetrate the skin, causing
death or serious injury. Relieve hydraulic pressure
before servicing any hydraulic component.
