Illustration 1 g00641023Note: Do not use additional hydraulic force in order to make contact with the bucket stops. Take all measurements at the time of initial contact in order to prevent twisting.
Tilt back the bucket against upper rack stop (1). Check for uneven contact between the tilt linkage and the boom.
Tilt back the bucket completely. Check for uneven contact between the bucket and lower rack stops (2). Note: Cracking can occur on the boom or on the bucket if dump stop (3) on the bottom of the boom does not fully contact the dump stop on the bottom of the bucket. Use the following steps to identify this problem.
Clean dump stop (3) and the dump stop on the bucket.
Apply a light coat of grease to the dump stop (3). The grease will help to determine the amount of contact that is being made when the dump stop (3) contacts the dump stop on the bucket.
Tilt the bucket so that dump stop (3) and the dump stop on the bucket contact each other. Partially tilt back the bucket in order to inspect the alignment.
Inspect the dump stops and determine the amount of contact. If even contact is being made across the dump stops, no further action is required. Reference: If uneven contact exists, refer to Special Instruction, REHS0250, "Boom Repair and Bucket Stop Alignment" for instructions about repairing the bucket stops.
