Komatsu 198-54-58111 Cushion Mount
Komatsu 198-54-58111 Cushion Mount is a rubber-metal mounting component suitable for compatible Komatsu heavy equipment. The same reference is also commonly searched in compact form as Komatsu 1985458111 Cushion Mount. It is designed to help isolate vibration, absorb repeated impact, and maintain a stable connection between mounted structures during demanding operation.
Komatsu identifies reference 198-54-58111 as a Mount within the Cab/Guard group. Parts documentation for the D475A-3 also lists the same reference as a cushion within the floor mounting assembly. This type of application requires controlled vibration isolation and stable structural support during continuous machine operation.
BCE Parts lists reference 198-54-58111 for D355C-3, D375A, D375A-5D, and D475A-3 machines. Because machine configurations can vary according to model and serial range, the reference on the removed component and the relevant machine information should always be checked before ordering.
During operation, cushion mounts may be exposed to continuous vibration, shock loads, dust, moisture, and repeated compression. Over time, rubber fatigue, cracking, deformation, or separation around the metal sections can reduce vibration isolation and allow excessive movement between connected structures.
Regular inspection of the mounting surfaces, rubber body, fasteners, and surrounding components can help identify wear before it affects machine stability. A worn mount should be replaced when excessive movement, visible cracking, deformation, or deterioration is detected.
The 1985458111 Cushion Mount should be installed using the correct mounting hardware and on clean, undamaged contact surfaces. BCE Parts supplies this product as an aftermarket replacement suitable for compatible Komatsu equipment.
