![]() ![]() Keep in mind that the rubber track may need further adjustment after a few hours of operation, as it will become looser. Switch on the machine and engage the forward gear to check the tension. The centre of the track should have about two to three centimetres clearance from the undercarriage. Then pump grease inside using the grease gun in order to adjust the tension of the rubber track. Use paper towels to clean the inside of the access hole and the grease valve before reinstalling it. One operator will have to activate the forward gear at very low speed, while a second operator will have to push the track over the idler wheel. Next, move the track so that it fits over the front idler wheel. You can now lift the track over the rear sprocket and idler wheel. If the track is mounted incorrectly it will instead push the mud under the machine. Lift an excavator bucket safety pin with a key or a screwdriver. The bucket is a large scoop on the end of the boom. The boom is the long arm that extends from the excavator. The track must be mounted in the correct way because if the excavator is working on very soft materials, this will push the mud towards the outside of the excavator, thus gaining more traction. Remove safety pins from the excavator boom and bucket. You must ensure that the tracks are mounted with the 'V' pointing towards the front idler. changing bushings & pins on Bobcat 331 mini excavator full video with all details, a condensed version for more experienced mechanics coming up next. Rubber tracks on excavators are often directional, as they have a V-shape on the pattern. We do not recommend using an iron pole in order to preserve the good condition of the track and undercarriage! Step 4: Position the tracks correctly Leverage between the track and the front undercarriage until it moves and then move it away from the rear toothed wheel. The operator should start the machine and place a tension bar (possibly wooden) along the idler wheel first and the sprocket later. You can accelerate the retraction process by pushing on the centre of the track with one foot. By loosening the valve, the grease will begin to escape as the tension along the crawler track begins to decrease. On the side of the undercarriage there is an access hole. This is to prevent the lever from being accidentally bumped, which could cause the machine to fall and injure the person changing the crawler track. Make sure that the operator lifts the safety lever. With the arm and bucket pushing down, the mini-excavator will lift up, allowing you to work on its undercarriage. Then push the arm and bucket down into the ground at the front end. Push the blade into the ground at the rear side. Customers today often purchase more than one attachment to increase the machine’s utilization. Now let's look at the steps for track replacement.

The bucket pin will slip down into its correct position and now you can crowl the bucket out to line up the bucket pin holes ready for the pin to go through. Continue to to crowel the bucket all the way in and lift up the bucket. Now crowel the bucket closed to allow the bucket pin to slot into the excavator hitch. Step 5: Pick up the Bucket and Replace Safety Pin With the mini excavator hitch crowled open, bring it around the back of the bucket and in between the bucket ears. This will help the boom to have smaller movements and be much smoother. Once done, reduce the throttle speed to its slowest position. In preparation to pick up the bucket, make sure that it’s in the right position with the hitch on the far side and squared up to the mini excavator so that you can easily pick it up.
