LEVER 3020056 - Caterpillar

Installation Procedure
Perform this procedure as the procedure is described in the following steps:Ensure that the quick coupler is compatible with the host machine. For more information, consult your Caterpillar dealer.
In order to properly install the hydraulically actuated Pin Grabber Coupler, the host machine must be equipped with the appropriate recommended Caterpillar hydraulic control kit or an equivalent kit. Regardless of the source, any non-Caterpillar hydraulic control kit must provide the same system functions as the recommended Caterpillar hydraulic control kit in order to ensure safe operation of the coupler.
In order to provide a stable operating condition, the host machine must be on flat, level ground. The host machine must be blocked in order to prevent inadvertent movement.The quick coupler must be supported in order to prevent inadvertent movement. Position the quick coupler in order to prevent unnecessary climbing and unnecessary bending.Optimum alignment of the bores will prevent the use of unnecessary force when you install the pins. Never check the alignment of the bores with your fingers. Use the proper tools in order to check the alignment of the bores.A retaining pin can fly out when the retaining pin is struck with force. The area must be clear of people when you drive retaining pins.When you strike objects, chips and other debris can fly. Before striking any object, make sure that no one can be injured by the flying debris. Always wear safety glasses.
Before you install the coupler on the host machine with a D linkage, you must measure the diameter of the pins that are on the work tool. If the pins are not the same size, you must use sleeves on the smaller pin. In order for the coupler to work properly, the pins must be the same size. Refer to Table 2 for the linkages, the part number of the sleeve, and the quantity of sleeves that are required for the installation.

Position the quick coupler on the ground in front of the host machine. Make sure that the hook is oriented away from the machine. Align the quick coupler with the end of the stick.

Place the O-Ring Seals (1) just over the edge of the main frame of the coupler.
Illustration 3 g00604930
Slowly lower the stick into the main frame of the coupler. This will slowly pull the O-Ring Seals (2) into the proper position.
Continue to lower the stick into the main frame of the coupler. Check that the O-Ring Seals do not enter the pin bore in the main frame of the coupler.
Illustration 4 g00604931
Lower the stick completely until the pin bores on the main frame of the coupler and the pin bores on the stick align.Note: Repeat the same procedure for the power link.
Install the mounting pins. Refer to the Operation and
