Description of Change: The location of tilt back and dump stops on both the work tool and lift arm are provided here. This document describes the procedure for adjusting the stops on the dealer or the customer installed buckets. Machines with buckets that have been installed at the factory do not need to make this adjustment in order to prevent structural damage. Reworking the bucket stops for the tilt back function can minimize bucket movement and material spillage that may occur during travel with a loaded bucket.
Adaptable To: This rework procedure is adaptable to the machines that are listed above.

Rework Procedure for the Bucket Stops
 |
Personal injury can result from flame cutting or welding on painted areas. The effect of gasses from burned paint is a hazard to the person doing the cutting or welding. Do not flame cut or weld on painted areas. |
 |
|
Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc. Welding can cause fumes, burn skin and produce ultraviolet rays. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working. Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death. Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts. See "American National Standard Z49.1, Safety in Welding and Cutting" published by the American Welding Society.

Note: Read all instructions and understand all instructions before you begin the rework procedure.
Tilt Stops
- Fully load the bucket with the densest material that is available on-site.
- Place the bucket linkage in the travel position with the bucket in the tilt back position to the limit of the cylinder.
- Measure the gap between side plate (2) of the lift arm assembly and bucket stop (1) at each end of the stop. Refer to Illustration 4. Repeat this measurement for both bucket stops.

- Use the dimensions that were obtained in Step 3 to create two shims for both bucket stops from plate steel. Ensure that the width of the shim (3) is equal to the width of side plate (2). This will reduce the chance of permanent deformation to the lift arm assembly upon impact of the bucket stops.

- Chamfer both edges of the shim (3). Use a 8 mm (0.32 inch) bevel weld to attach the shim to the bucket stops. Refer to Illustration 6.
Note: Welding the shim to the side plates of the lift arm assembly will cause the side plates to crack. Weld the shim to the existing bucket stops only.

(4) Bucket stop (2) Side plate | |
Note: Dump Stops will not be applicable on the 980H machines.
The bucket dump stop (4) should contact the side plate (2) of the lift arm assembly only when the milled surfaces at the tilt lever (6) and crossmember (7) make contact.
- Raise the lift arm assembly to the maximum height position.
- Slowly place the bucket in the dump position. Stop when the tilt lever (6) makes contact with the lift arm crossmember (7).
If contact is made between the bucket dump stops (4) and the left and the right side plates (2) of the lift arm assembly, then no adjustment is needed. If there is a gap a shim should be added to the bucket so the stops contact the side plates. If the machined surfaces of the tilt lever (6) and the crossmember (7) are unable to touch, remove material from the bucket stops until the machined surfaces are able to touch.
