7C3173 Turbocharger for Caterpillar Equipment

7C3173 is a turbocharger for Caterpillar equipment. The part is used on Caterpillar track-type tractors, autograders, wheel-type loaders, industrial engines, and pipe-layers listed below. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The supplied application data identifies the part by the Caterpillar reference number 7C-3173 and associates it with several Caterpillar machine and engine models. Fitment depends on the exact machine configuration and the part number installed on the equipment, so the reference number and model designation should be checked before installation.

Fitment

The 7C3173 turbocharger is listed for the following Caterpillar equipment and engine applications:

• Track-type tractors: Caterpillar 57H, 8, 8A, 8SU, 8U, and D8N.
• Autograders: Caterpillar 16G and 16H NA.
• Wheel-type loader: Caterpillar 980C.
• Industrial engines: Caterpillar 3406B and 3406C.
• Pipe-layer: Caterpillar 578.

For track-type tractor applications, the listed models are 57H, 8, 8A, 8SU, 8U, and D8N. The autograder applications are 16G and 16H NA. The wheel-type loader application is 980C. The industrial engine applications are 3406B and 3406C, and the pipe-layer application is 578.

The part is therefore associated with both complete Caterpillar machines and Caterpillar industrial engine applications. The equipment type is included with each application to distinguish the machine series from the engine model designations.

Cross-reference numbers

• 7C3173 — product SKU and non-hyphenated part number format.
