(A) Adjusting shims
(B) Dimension between the height of the front idler tread and the height of the roller tread The following check is for undercarriage systems that have the conventional idler.The height of the front idler tread should always be higher than the height of the roller tread. The dimension (B) is set approximately to 9.0 mm (.35 inch) at the factory. Dimension (B) decreases as the undercarriage wears. If a rebuilt idler or a new idler is installed with track rollers that are worn, dimension (B) decreases.Adjustment of the front idler to the correct height can improve the ride of the tractor and the performance of the dozer. Use the following procedures to determine the best operating position.If the machine is operated on FIRM UNDERFOOT conditions and excess vibration occurs, shims can be removed in order to raise the front idler.If the machine is operated on SOFT UNDERFOOT conditions and dozing performance is poor, shims can be installed in order to lower the front idler. Lowering the front idler can improve dozing performance. If ground rippling by the dozer or excess vibration occur in soft material, shims can be removed in order to raise the front idler.Consult your Cat dealer for detailed information about checking the idler and about adjustments to the idler.
