Start By:
- Release the system pressure.

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. |

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. |

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. |

- 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.

- Remove bolts (4) and retention plate (5) .
- Remove pin (6). Use a suitable lifting device to raise the head end of wheel lean cylinder (3) upward.
- Remove bolt (7) and retainer (8) .
- Remove wheel lean cylinder (3) .
Installation Procedure
- Install wheel lean cylinder (3) in the reverse order of removal.
- The gap between the rod end of wheel lean cylinder (3) and retainer (8) must be 0.76 mm (0.030 inch).
- Check the hydraulic oil level. Refer to Operation and Maintenance Manual, "Hydraulic System Oil Level - Check".

When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death. |

(A) Dimension from the face to the bearing ... 7.80 ± .50 mm (0.307 ± 0.020 inch)
(B) Dimension from the face to the bearing ... 7.40 ± 0.50 mm (0.2913 ± 0.0197 inch)
(1) Use a 46 mm socket to remove and install the bolt. Tighten the bolt to a torque of 1800 ± 200 N·m (1328 ± 148 lb ft).
(2) Lubricate sealing lips with lubricant that is being sealed.
(3) Apply Tooling (C) to the seal groove prior to assembling the wiper seal.
(4) Lubricate the threads of the head with Tooling (D). Tighten the head to a torque of 600 ± 130 N·m (440 ± 95 lb ft).
