9N2837 Valve Insert for Caterpillar Equipment

9N2837 is a valve insert used in Caterpillar equipment, including construction machines, engines, compactors, loaders, skidders, tractors, and marine engine applications. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The part is listed for the Caterpillar equipment and engine applications shown below. The fitment information includes complete machine designations where provided, as well as engine series used in generator, industrial, marine, and truck applications.

Fitment

• Caterpillar Cold Planer: PR-1000
• Caterpillar Excavator: 215, 225
• Caterpillar Gen Set Engine: 3208
• Caterpillar Industrial Engine: 3204, 3208
• Caterpillar Marine Engine: model designation not specified in the available data
• Caterpillar Pneumatic Compactor: PS-500
• Caterpillar Track Loader: 931B, 943, 953
• Caterpillar Track Skidder: D4HTSK II
• Caterpillar Truck Engine: 3208
• Caterpillar Wheel Loader: 926
• Caterpillar Wheel Tractor: 613B, 613C

For machine identification, the listed applications are grouped by Caterpillar equipment type. The PR-1000 application corresponds to a cold planer; models 215 and 225 correspond to excavators; PS-500 corresponds to a pneumatic compactor; and models 931B, 943, 953, and 926 correspond to track or wheel loaders as indicated above.

The engine applications are listed separately because the same 9N2837 valve insert is specified for Caterpillar 3208 engines in generator-set and truck-engine use, as well as for Caterpillar industrial engines. The available fitment data also identifies the Caterpillar 3204 industrial engine and a marine engine application without a specific marine model number.

Specifications

The available product data does not specify a separate cross-reference number, material grade, thread specification, installation position, or additional components supplied with the valve insert.
