The part is used on selected Caterpillar excavators, pipelayers, track-type tractors, wheel dozers and wheel loaders with 3304 or 3306 engines. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The listed model applications cover several Caterpillar machine categories. The excavator applications are 235, 330 L and 330B. The pipelayer application is 572G. The track-type tractor applications are D6H, D7G and D7H. The wheel dozer application is 814B, and the wheel loader application is 966F.

Fitment should be checked against the machine model and engine configuration before installation, because the supplied data identifies the equipment applications by model and does not provide a complete machine serial-number range.

Specifications

The available product data does not specify the damper dimensions, mounting arrangement, material, thread parameters, weight or included installation components. These parameters are therefore not listed as part of this description.
