Outrigger Cylinder Installation
1. Lubricate the outrigger cylinder pins with multi-
purpose lithium-based grease.
2. Use a sling and hoist or other suitable lifting device
to help install the cylinder. Orient the cylinder with
the cylinder eyelet on top and the rod eyelet on the
bottom.
3. Install the upper cylinder pin. Drive the lubricated
cylinder pin through the outrigger frame mount and
the cylinder eyelet, aligning the mount pin bolt holes
with the outrigger cylinder mount holes. Secure the
outrigger cylinder with the capscrews and nuts.
Torque the capscrews and nuts to specification.
Refer to the fastener torque chart in Section 2.3,
“Torques.” Repeat with the lower cylinder pin.
4. Use new flat-faced oiled o-rings when installing the
upper and lower hydraulic hoses. Install and tighten
the hoses onto the appropriate fittings.
On Model 10054, connect the pressure switches.
5. Start and run the engine at approximately one-third to
one-half throttle for about one minute without moving
the vehicle or operating any hydraulic functions.
6. Inspect for leaks and check the level of the hydraulic
fluid in the reservoir. Shut the engine OFF. Add
hydraulic fluid if required.
7. Conduct an outrigger cylinder hydraulic circuit test
following the procedure that follows.
8. Wipe up any hydraulic fluid spillage in, on, near and
around the vehicle, work area and tools.
g. Outrigger Cylinder Circuit Test
1. Lower the outrigger cylinder to the ground.
2. Apply full down pressure until the front wheels lift off
the ground.
3. Watch for any drifting.
4. If drifting occurs, raise and lower the outriggers
several times and repeat Steps 1 and 4 until no
drifting occurs.
WARNING:
Avoid prolonged engine
operation in closed areas with inadequate
ventilation. Failure to properly ventilate exhaust
fumes can result in death or serious injury.
WARNING:
Escaping hydraulic fluid
under pressure can penetrate the skin, causing
death or serious injury.
