The product identification is based on the Caterpillar equipment part number 8Y4139. The available product data does not specify individual Caterpillar machine models or series, so model-level fitment is not listed. Compatibility should be checked by matching the part number and the dimensions with the component installed on the machine.

Cross-reference numbers

The numbers 8Y4139, 3B0641, and 5H6030 are listed for identification and interchange reference. The applicable number depends on the Caterpillar equipment configuration and the bearing assembly in which the lining is installed. The cross-reference information does not define a machine model by itself.

The listed dimensions are length 14 cm, width 1.8 cm, and depth 14 cm. The stated weight is 0.2 lb. No material specification, thread data, mounting position, or kit contents are provided for this part. The item is described as a single lining rather than a kit.

Before installation, compare the removed part with the listed dimensions and verify the reference number marked in the equipment parts documentation. The available information confirms compatibility with Caterpillar equipment by part-number reference, but does not identify a specific machine model, component location, or equipment series.
