HOW TO ADJUST
Track tension is controlled by a track adjuster. Tension adjustments are made by pumping or draining grease through the track adjuster valve.
Jason Goodson, Regional Service Manager for Hyundai Construction Equipment Americas shares some easy steps for achieving proper track tension for your crawler excavator. He writes that you should first turn the upper part of the excavator, pointing the boom perpendicular to the travel direction and the arm perpendicular to the ground. Keep the bucket at ground level. Elevate the track on one side above the ground. Then, on the lifted side, run the travel, allowing the track to revolve several times. This helps to knock away debris and loosen the binding links. Stop the tracks and turn on the safety. While remaining in the cab, have someone measure the track at its lowest point, from the bottom of the frame to the upper face of the track shoe. See if it matches the recommendations in your manual.
He goes on to say that the grease inside the adjuster cylinder helps to maintain tension. Using a grease gun, insert more grease to tighten the track . Release grease with a wrench to loosen it. Be sure to use proper safety equipment, as grease is under extreme pressure and could cause injury.
