Put a mark on the tubular section of the front roller frame. This mark should correspond with the mark on the rear roller frame. Measure the distance between the two marks on the front roller frame. If the distance between the two marks is greater than 4.5 mm (0.18 inch), inspect the track roller frame guides for wear.Repeat the entire procedure for the other side of the machine.
Never build up the track roller frame guides with hard-face welding. This will cause serious wear damage to the guide slots in the front track roller frame.
