7M7186 Engine Bearing for Caterpillar Equipment

7M7186 is an engine bearing used in Caterpillar equipment, including the D320A industrial engine and machines equipped with this engine. The part is a connecting rod bearing for the D320A engine application. This is a new aftermarket spare part manufactured by CTP (Costex Tractor Parts).

The bearing is identified by part number 7M7186 and is listed for Caterpillar machines in several equipment categories, including track-type tractors, autograders, wheel bulldozers, pipe layers, and track loaders. Fitment depends on the machine model, engine configuration, and the bearing specification required for the particular engine assembly.

Fitment

• Caterpillar D4D track-type tractor
• Caterpillar 12E autograder
• Caterpillar 824 wheel bulldozer
• Caterpillar D320A industrial engine
• Caterpillar 561B pipe layer
• Caterpillar 955H track loader
• Caterpillar 955K track loader
• Caterpillar 977A track loader
• Caterpillar 977H track loader
• Caterpillar 977K track loader

The listed applications identify the equipment model or engine family for which 7M7186 is catalogued. The D320A engine application is specifically associated with the connecting rod bearing use. On machines such as the Caterpillar 955H, the part is used in the engine connecting rod bearing arrangement when the installed engine and bearing specification correspond to the required part number.

Before installation, the bearing number and engine configuration should be checked against the identification information for the machine. The model designation alone may not determine the required bearing size or complete engine bearing set. This description does not specify an undersize or oversize version because no such dimension or classification is provided in the available product data.

Specifications

7M7186 is described as an individual engine bearing rather than a complete engine bearing set. The available information does not state whether the package contains a pair, a complete set for one engine, or additional installation components. Bearing quantity, shell position, journal size, clearance, thickness, and dimensional tolerances are not specified.

For correct application, compare the number marked on the removed bearing or the engine parts documentation with 7M7186. The Caterpillar model, engine model, and the required connecting rod bearing specification should be checked together before the part is installed.
