CABLE-THROTTLE 1164386 - Caterpillar

Unexpected machine movement can cause injury or death.To avoid possible machine movement, move the hydraulic lockout control to the locked position and attach a Special Instruction, SEHS7332, "Do Not Operate" or similar warning tag to the hydraulic lockout control.
Improperly adjusted bucket clearance could cause galling on the contact surfaces of the bucket and stick, resulting in excessive noise and/or damaged O-ring seals.

(11) PlateThe clearance of the bucket control linkage on this machine can be adjusted by shimming. If the gap between the bucket and the stick becomes excessive, adjust bucket clearance (7) to 0.5 to 1 mm (0.02 to 0.04 inch).Two shims of different thickness are used at location (8). The thicknesses of the shims are 0.5 mm (0.02 inch) and 1.0 mm (0.04 inch).
Position the machine on a level surface and lower the bucket to the ground.
Slowly operate the swing control lever until stick boss (4) and the bucket boss (6) are in full face contact at no gap (5). This will help to determine the total clearance of the connection point of the stick and of the bucket.
Move the hydraulic lockout control to the LOCKED position. Stop the engine.
Measure bucket clearance (7), which is the existing total clearance.
Determine the number of shims that need to be removed from shims (2) by using the following calculation:Subtract 0.5 mm (0.02 inch) or 1.0 mm (0.04 inch) from bucket clearance (7).
Remove the appropriate number of shims at location (8) to meet the above thickness. Make sure that you use a minimum of three 0.5 mm (0.02 inch) shims. To remove the shims, remove bolts (9), washers (10), and plate (11).
After the correct number of shims has been removed and pin (1) is aligned with the pin hole, install plate (11), bolts (9), and washers (10). Tighten the bolts to 240 40 N m (175 30 lb ft).
After installation, make sure that bucket clearance (7) is still correct.
