PLATE AS 3598656 - Caterpillar

Release all the pressure in the hydraulic system prior to disconnecting any hydraulic lines or removing any loader linkage pins. If the hydraulic oil pressure is not released completely, oil can spray out of the oil lines under very high pressure. Also, there will be binding of the pins in their bores. After removal of any of the pins the loader linkage can separate suddenly. Failure to release system pressure completely can cause personal injury.
2. Lower the lift arms to the ground and be sure all hydraulic pressure is released. 3. Fasten a nylon strap and a hoist to the tilt cylinder, or put wood blocks between the tilt cylinders and the lift arms to prevent movement of the tilt cylinders during the removal of the linkage plates. 4. Put wood blocks between the coupler assembly and the lift arms to prevent the coupler from moving after the linkage plates are removed.5. Remove bolts, nuts and washers (1), and remove plates (3) from the machine.6. Note the position of washers (4) and (2) so they can be reinstalled to their original position.7. If necessary, remove the washers and the pins from the lever assembly and the lift arms. The following steps are for the installation of the linkage plates.8. Be sure all pins slide freely in their bores before assembly. Lubricate all pins, pin bores and seals with 5P0960 Multipurpose Grease before assembly.9. Install the tilt linkage plates in the reverse order for removal.10. Install pins (2) with the grease hole pointed toward the rear of the vehicle. Be sure washers (4) are installed in their original position.11. If any loader linkage parts were replaced with new ones, see Implement Control Group in Specifications for the correct amount of washers (4) to use in order to keep the lift arms centered in the coupler assembly.12. Be sure pins (2) protrude evenly from each plate and then tighten nuts (1) to a torque of 300 30 N m (220 22 lb ft).
