Group 4 – Inspection and Adjustment Square Sensors Service Instruction: Hook-Lift L and LA | 13298 Edition 5 | 2019-10-20... - Page 20 Group 4 – Inspection and Adjustment Operate the hook-lift and fully lower it in fast mode (regenerative function). Verify that the fast lower function slows down to normal speed when lowering the hook. Hook- lifts equipped with this option have a sensor that causes the hook-lift to slow down before the intermediate-section reaches the sensors for stop of shunting.
- Page 21 Group 4 – Inspection and Adjustment Inspect the hook-lift's main valve block as shown and described below. Both the air controlled and electrically controlled versions are shown. 1. Turn the vehicle OFF. 2. Move the actuator for each section of the valve block. Verify that they move eas- ily, without any restriction, and that there is no evidence of malfunction in the movement of them.
- Page 22 Group 4 – Inspection and Adjustment 1. Operate the hook-lift and engage the hook with a lifting-bracket on a body. Then operate the safety-hook. Verify that it functions correctly and fastens the hook onto the lifting-bracket. Check that the safety hook moves freely and smoothly, and that it does not leak air.
- Page 23 Group 4 – Inspection and Adjustment 4:12 Check the free play in the hook-post, as shown below. The play must be less than 10 mm when moved from side-to-side, as shown below. 4:13 Raise the auxiliary-arms and inspect them as follows: 1.
- Page 24 Group 4 – Inspection and Adjustment 4:14 Inspect the shunting axle components, as follows: 1. Inspect the housings for the shunting-axle, on the sub frame. Check for damage or wear. 2. Inspect the locking-arms for the shunting-axle, as shown above. Check for dam- age and wear.
- Page 25 Group 4 – Inspection and Adjustment 1. Position the hook-post so that it is in the shunting position with the extending- section extended a bit. 2. Leave the hook-post in position and observe it. Observe to see whether or not the extending-section or the hook-post moves.
- Page 26 Group 4 – Inspection and Adjustment NOTE: This is optional equipment. It is not standard. 1. Operate the spreader flap and verify that it functions correctly. Make sure it moves freely and without any resistance. 2. Release the spreader flap and verify that it returns to its parked position - fully. Measure and make sure that it sits within the tolerances shown below.
- Page 27 Group 4 – Inspection and Adjustment 4:20 Inspect the tip axle's bearings, as follows: 1. Check the bearings for ware and excessive free-play. 2. Make sure that the grease points for the bearings are free from damage. 3. Inspect the tip axle for material damage. 4:21 Verify that the rollers on the back of the hook-lift move freely and that the bearings do not have play in them.
- Page 28 Group 4 – Inspection and Adjustment 4:23 Verify that the hydraulic pump functions correctly, as follows: 1. Operate the hydraulic pump under load and listen for any unusual noises that would indicate that there is a problem with it. 2. Inspect the hydraulic pump's supply and return hoses for damage. 3.
- Page 29 Group 4 – Inspection and Adjustment 2. Make sure that the high-pressure-filter's body is clean, then remove the internal filter and replace it with a new one. 4:27 Check all valves for the hook-lift and make sure that they function correctly and that they do not leak.
- Page 30 Group 4 – Inspection and Adjustment 4:29 Open and inspect the two solenoid boxes for the hook-lift. Inspect the: cables, relays, valves, and fasteners for damage or evidence of corrosion. The big solenoid box is located either to the side of the hook-post or to the side of the sub-frame, as shown below.
