7W4154 Rotor for Caterpillar

The 7W4154 rotor is a replacement component for Caterpillar engine-generator sets and is listed in the Air Starter Motors category. The part is used with Caterpillar equipment identified by the 3516, 3516B, 3516C, 3606, 3608, 3612, and SR4 model designations.

This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts). The Caterpillar reference for the component is 7W4154, which is also the SKU assigned to this product.

The available application information identifies the part for Caterpillar engines and generator sets rather than for a general machine attachment. Before installation, the equipment model and the number marked on the removed rotor should be checked against the information below.

Fitment

The rotor is listed for the following Caterpillar equipment model and series designations:

• Caterpillar 3516
• Caterpillar 3516B
• Caterpillar 3516C
• Caterpillar 3606
• Caterpillar 3608
• Caterpillar 3612
• Caterpillar SR4

The listed applications include Caterpillar engine-generator sets. The model designations 3516 and 3516B are each represented once in the fitment list, although they may appear more than once in source application records. The same applies to the 3608 designation.

Fitment should be confirmed using the complete equipment identification and the existing component number, because the supplied application data contains model designations but does not specify a serial-number range, engine arrangement number, or generator configuration.

Cross-reference numbers

• Caterpillar part number: 7W4154
• CTP product SKU: 7W4154

The available data provides the same 7W4154 number for the Caterpillar equipment reference and the CTP product identification. No additional supplier numbers or separate replacement numbers are specified.

Specifications

The dimensions are stated as length, width, and depth in the supplied product data. The available specification does not identify the rotor material, shaft or bore dimensions, thread details, installation position, rotation direction, or additional components included with the part.
