PLATE 1968294 - 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.
Impoperly adjusted work tool clearance could cause galling on the contact surfaces of the work tool and stick, resulting in excessive noise and/or damaged O-ring seals.

If the gap between the work tool and the stick becomes excessive, adjust work tool clearance (3) to 0.5 to 1 mm (.02 to .04 inch).Two shims of different thickness are used at location (9). The thicknesses of the shims are 0.5 mm (0.02 inch ) and 1.0 mm (0.04 inch).

Area for linkage adjustment
Position the machine on a level surface and lower the work tool to the ground.
Slowly operate the swing control lever until stick boss (2) and the work tool boss (11) are in full face contact at no gap (1). This will help to determine the total clearance of the connection point of the stick and of the work tool.
Place the hydraulic lockout control in the LOCKED position and stop the engine.
Measure work tool clearance (3), which is the existing total clearance.
Determine the number of shims that need to be removed from shims (4) by using the following calculation:Subtract 0.5 mm (0.02 inch ) or 1.0 mm (0.04 inch) from work tool clearance (3) .
Remove the appropriate number of shims at location (9) in order 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 (7), washers (8), and plate (6) .
After the correct number of shims has been removed and pin (5) is aligned with the pin hole, install plate (6), washers (8), and bolts (7). Tighten bolts (7) to a torque of 240 40 N m (175 30 lb ft).
After installation, make sure that work tool clearance (3) is still correct.
