Bucket Cylinder - Remove and Install
SMCS - 5457-010
Removal Procedure
Cylinders equipped with lock valves can remain pressurized for very
long periods of time, even with the hoses removed.
Failure to relieve pressure before removing a lock valve or
disassembling a cylinder can result in personal injury or death.
Ensure all pressure is relieved before removing a lock valve or
disassembling a cylinder.
Note: Cleanliness is an important factor. Before the disassembly procedure, the exterior of the component
should be thoroughly cleaned. This will help to prevent dirt from entering the internal mechanism.
NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Caterpillar Dealer Service
Tool Catalog" for tools and supplies suitable to collect and contain
fluids on Caterpillar products.
Dispose of all fluids according to local regulations and mandates.

3. At operating temperature, the hydraulic oil is hot and under pressure.
Hot oils can cause burns.
To prevent possible personal injury, release the pressure in the work
tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits,
and the hydraulic oil tank at the filler cap before any hydraulic lines or
components are disconnected or removed.
Remove the filler cap only when the engine is stopped and the filler cap
is cool enough to touch.
Note: Put identification marks on all lines, on all hoses, on all wires, and on all tubes for installation
purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep
contaminants from entering the system.
1. Release the hydraulic system pressure. Refer to Disassembly and Assembly, "System Pressure -
Release".

of bucket cylinder (4) into the brackets on top of the stick. Make sure that the pin bores in the stick
are in alignment with the pin bores in the bucket cylinder. Make sure that the grease fittings in the
head end and in the rod end of bucket cylinder (4) are facing away from the stick.
2. Install the shims on both sides of the bucket cylinder at the bore for pin assembly (7) .
3. Install pin assembly (7) .
4. Install retaining bolt (6) . Tighten retaining bolt (6) to a torque of 460 ± 60 N·m (340 ± 44 lb ft).

Start By:
a. Release the hydraulic system pressure. Refer to Disassembly and Assembly, "Hydraulic
System Pressure - Release" .
NOTICE
Keep all parts clean from contaminants.
Contamination of the hydraulic system with foreign material will
reduce the service life of the hydraulic system components.
To prevent contaminants from entering the hydraulic system, always
plug or cap the lines, fittings, or hoses as they are disconnected. Cover
any disassembled components and clean them properly before
assembly.
Clean the hydraulic system properly after any major component
exchange or especially after a component failure, to remove any
contamination.

10. NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.
Refer to Special Publication, NENG2500, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on
Cat®
products.
Dispose of all fluids according to local regulations and mandates.
Note: A hydraulic oil sample should be obtained before any maintenance is performed in order to
establish the system contaminant level. Refer to Fluid Analysis Laboratory Guide, SEBF3116,
"Obtaining an Oil Sample for S·O·S Analysis". Refer to Operation and Maintenance Manual,
"Sampling Interval and Location of Sampling Valve" for the correct location.

Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly cleaned
in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts.
Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are
worn or damaged, use new parts for replacement. All disassembly and all assembly procedures
must be performed on a clean work surface and in a clean hydraulic area. Keep cleaned parts
covered and protected at all times.
Note: O-rings, gaskets, and seals should always be replaced. A used O-ring seal may not have the
same sealing properties as a new O-ring seal. Use Tooling (A) during the assembly procedure.
Note: Apply a light film of hydraulic oil to all components before assembly.
