Stick Cylinder - Remove and Install

SMCS - 5458-010

Removal Procedure

Cylinders equipped with lock valves can remain pressurized for verylong periods of time, even with the hoses removed.

Failure to relieve pressure before removing a lock valve ordisassembling a cylinder can result in personal injury or death.

Ensure all pressure is relieved before removing a lock valve ordisassembling a cylinder.

Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of thecomponent should be thoroughly cleaned. This will help to prevent dirt from entering the internalmechanism.

NOTICE

Care must be taken to ensure that fluids are contained duringperformance of inspection, maintenance, testing, adjusting and repairof the product. Be prepared to collect the fluid with suitable containers

before opening any compartment or disassembling any componentcontaining fluids.

Dispose of all fluids according to local regulations and mandates.

Personal injury can result from hydraulic oil pressure and hot oil.

Hydraulic oil pressure can remain in the hydraulic system after theengine has been stopped. Serious injury can be caused if this pressure is

not released before any service is done on the hydraulic system.

Make sure all of the work tools have been lowered to the ground, andthe oil is cool before removing any components or lines. Remove the oil

filler cap only when the engine is stopped, and the filler cap is coolenough to touch with your bare hand.

Start the engine and fully retract the bucket cylinder and the stick cylinder. Lower the boomuntil the bucket is lowered onto the ground. Shut off the engine.
