40-165 Buffer Rubber

Caterpillar 373-4315 Buffer Rubber

The Caterpillar 469-2341 Rubber Buffer is an aftermarket replacement component used at the dump body contact points of articulated trucks. Supplied by BCE Parts under code 40-165, it is also listed under the Caterpillar 373-4315 Rubber Buffer reference. It cushions contact between the body and its supporting surfaces, helping absorb impact and reduce associated vibration and noise.

Also listed under the Caterpillar Rubber Buffer reference, this component features a raised rubber cushioning section and a mounting plate with four fixing holes. The rubber section forms the contact surface, while the plate provides the attachment points needed to secure the buffer in position.

During loading and dumping operations, body contact points are exposed to repeated movement and impact. The buffer helps soften contact when the body meets its supporting surfaces. Maintaining the condition of the rubber section helps preserve this cushioning function and limit the effects of repeated contact on the body support surfaces.

Compatible models include Caterpillar 725, 725C, 725C2, 730, 730C, 730C2, 735, 735C, 745 and 745C articulated trucks. Application depends on the machine configuration and the specified part reference.

BCE Parts supplies this Caterpillar 373-4315 Rubber Buffer replacement for maintenance of the dump body support arrangement. Replacing a worn or damaged buffer helps restore cushioning at the designated contact points. This makes the condition of the buffer an important consideration during routine inspection of the body support components.
