The supplied application data identifies this part by the Caterpillar equipment brand and lists the compatible motor grader models below. Model designations are retained as provided for equipment identification and parts-matching purposes.

Fitment

• Caterpillar 140 motor grader
• Caterpillar 140B motor grader
• Caterpillar 14E motor grader

The listed fitment covers the Caterpillar motor grader models associated with SKU 4D2159 in the available product data. The information identifies the machine series and model designations, but does not specify a particular production year, serial-number range, engine arrangement, transmission configuration, or installation position. These details are therefore not added to the application list.

Before installation, the part number and the dimensions should be compared with the removed gear and the parts documentation for the specific machine. The model designation alone may not identify every machine configuration, so the equipment serial number and the existing part marking can be used for final application verification.

Specifications

The recorded dimensions are length 25.4 cm, width 23.8 cm, and depth 7 cm. The available data does not state the gear material, tooth count, pitch, bore diameter, keyway dimensions, mounting method, rotational direction, or the components supplied with the part. These parameters are not specified here.

No equipment-manufacturer or supplier cross-reference numbers other than SKU 4D2159 are provided in the available product information. Accordingly, no additional cross-reference numbers are listed.
