4 CYLINDER REPLACEMENT
If repair or replacement of a boom lift or outrigger hydraulic cylinder or its component parts becomes necessary, observe the following procedures in accordance with the safety precautions established in Section 1 of this manual.
Removing the hydraulic cylinder from the boom lift may require the use of specialized tools and lifting equipment. NEVER attempt to operate overhead hoists or cranes or related equipment without proper training, authorization and supervision. Perform all maintenance procedures only in an area that is well-lit and well-ventilated. Bil-Jax, Inc. is not responsible for personal injury or property damage resulting from the improper use of equipment or failure to follow all procedures and related safety precautions.
Direct all questions regarding cylinder removal and replacement to your regional Bil-Jax representative or to the Bil-Jax Service Department at 800-537-0540.

BIL-JAX 36XT
LIFT CYLINDER REPLACEMENT
Use the following procedure to remove and replace faulty or damaged hydraulic cylinders on the boom lift:
WARNING
Repair and removal of the hydraulic cylinders requires the use of lifting straps and an overhead crane or lifting gear to support the boom lift and hydraulic cylinders. Personnel should be thoroughly trained in the operation of these devices before attempting installation or removal. Hydraulic cylinders are heavy and may have hydraulic oil on their surface. Failure to use proper equipment or to securely support boom and boom cylinders can result in damage to lift components, serious injury or death.
Lower the boom until it is resting in a stowed position. When removing the slave cylinder, extend the articulating boom section until all pivot pins are exposed (approximately two feet).
Press and hold the emergency lowering valve on the back of the jib boom section to relieve all hydraulic pressure to the cylinder. Repeat this process for the upper and lower boom sections. Refer to the 4527A Operator’s Manual for emergency lowering valve locations and operating procedures.
Turn key switch to the OFF position and remove the key.
Locate the piston rod end of the cylinder to be removed (Figure 4-1). Unbolt and remove the retainer plate from each side of the pivot pin.
Verify that the cylinder is supported by lifting straps and an overhead hoist.
Remove the pivot pin using a hammer and a brass or hardwood drift.
Use an overhead crane or lifting gear to raise the boom section. Adequate clearance is necessary to reach the cylinder valve block and hydraulic hose ports.
Unplug the appropriate emergency lowering valve solenoid.
Tag and number all hydraulic hoses that attach to the cylinder valve block. Use a marker to label the valve block ports with the appropriate hose numbers.
Place absorbent cloths below the cylinder ports and detach hydraulic hoses from the cylinder. Elevate
hoses to prevent leakage. Plug or cap exposed hose fittings and cylinder ports.
At the base of the cylinder, unbolt and remove retainer plate from each side of the pivot pin.
Remove the pivot pin using a hammer and a brass or hardwood drift.
Lift and remove the cylinder using an overhead hoist and lifting straps.
Replace or reinstall the cylinder by following the above instructions in the reverse order of removal.
Actuate the hydraulic system and check for leakage. Tighten hydraulic fittings as needed.
Bleed trapped air from the hydraulic system by raising and lowering the boom with the reservoir fill port cap on but not tightened. Allow several minutes for trapped air to escape. Repeat as needed.

OUTRIGGER CYLINDER REPLACEMENT
Use the following procedure to remove and replace faulty or damaged hydraulic cylinders on the outriggers:
Lower the outrigger until the footpad is touching the ground. Do not transfer the weight of the boom lift onto the outrigger. Leave the weight of the boom on the trailer wheels.
Remove the bolts securing the outrigger cylinder rod guard (Figure 4-2). Remove the guard.
At the piston rod end of the cylinder, unbolt and remove the retainer plate from each side of the pivot pin.
Place a block of wood shoring between the outrigger beam and cylinder.
Remove the pivot pin using a hammer and a brass or hardwood drift.
Fully retract the cylinder.
Turn key to the off position and remove the key.
Tag and number all hydraulic hoses that attach to the cylinder valve block. Use a marker to label the valve block ports with the appropriate hose numbers.
Unplug the cylinder valve solenoid.
Place absorbent cloths below the cylinder ports and detach hydraulic hoses from the cylinder. Elevate hoses to prevent leakage. Plug or cap exposed hose fittings and cylinder ports.
At the base of the cylinder, unbolt and remove retainer plate from each side of the pivot pin.
Remove the pivot pin using a hammer and a brass or hardwood drift.
Lift and remove the cylinder using an overhead hoist and lifting straps.
