Tags: choose used excavator used excavator for sale used excavator Cat2013-10-07

In order to maintain the used excavator, you need to maintain the it properly and you need to parepare suitable tools.

Locate the track tension device and access plate on your excavator. Each excavator has a chassis system located in a different place based on its type and model.

Raise the excavator from the ground at least 6 inches using hydraulic jacks. Place the crane and bucket against the ground to keep the machine steady as you slide blocks underneath. Ensure the entire excavator is stable on the blocks and jacks before making repairs.

Remove the tension cover plate from the track frame if your excavator has one. Place the socket wrench against the grease jerk and slowly remove. Insert the Allen wrench into the hole and push on the check ball inside. Press a foot against the rubber track to loosen the tension and retract the tension/idler wheel.

Pull off the rubber track. Place the new track over the drive wheel sprocket with the metal links fitting into the sprocket teeth. Slide the rubber track over the tension/idler wheel with the use of the pry bar. Push the bottom of the track with your foot until the metal links straddle the wheel.

Reinsert the grease irk into the track tension frame. Pump grease into irk with a grease gun. Stop applying grease when the track frame sags 3 inches.

Start the excavator and place the engine on idle. Rotate the track in both directions for several turns with the control lever for the rubber track. Turn off the engine and check the sag. Continue to rotate the track if the sag is more than 3 inches.

Secure the tension cover plate when the track sag remains at 3 inches. Take out the blocks and lower the hydraulic jacks until the used excavator is on the ground.
