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.
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, PERJ1017, "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.
Hydraulic oil pressure can remain in the hydraulic system on this
machine after the engine and pump have been stopped. Serious injury
can result if this pressure is not released before any service is done on
the hydraulic systems. In order to prevent possible injury, release the
hydraulic system pressure before working on any fitting, hose, or
hydraulic component.
Lower all attachments to the ground before service is started. If the
hydraulic system must be serviced, tested, or adjusted with the
attachment in the raised position, the attachments and lift cylinders
must be supported properly.
Always move the machine to a location away from the travel of other
machines. Be sure that other personnel are not near the machine when
the engine is running and tests or adjustments are being made.
1. Release the system pressure. Refer to Operation and Maintenance Manual, "System Pressure -
Release".

2. Install Tooling (A) onto the hydraulic tank. Attach an air supply hose onto Tooling (A). Apply
138 kPa (20 psi). This procedure will pull a vacuum on the hydraulic system.

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.
1. Use Tooling (H) (not shown) and a suitable press in order to install bearing (9) in cap assembly
(4). Use Tooling (H) (not shown) in order to install seal (8) in cap assembly (4).

Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the
engine 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, and
the 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 cool
enough to touch with your bare hand.
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.
