139-8736-139-8737 1 Set Mounting Rubber — Cat

This set of mounting rubbers is designed to isolate engine vibrations and absorb shock, protecting the engine and chassis from excessive stress. Manufactured to meet stringent OEM standards, these components offer superior durability and resilience compared to worn or degraded mounts. Operators may notice increased engine noise, excessive vibration transmitted to the cabin, or visible cracking and deformation of the rubber when these mounts begin to fail.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first sign of failing mounting rubbers is often increased engine vibration felt throughout the machine. If ignored, this can lead to accelerated wear on adjacent components and potential fatigue cracks in the chassis. Continued operation with severely degraded mounts risks excessive stress on the engine and drivetrain, potentially causing misalignment or structural damage.

Installation Tip

Ensure the engine and mounting surfaces are thoroughly cleaned of all debris and old rubber residue before installation. Avoid overtightening the mounting bolts, as this can crush the rubber and compromise its vibration-dampening capabilities.

Service Note

Inspect the engine's exhaust system and transmission mounts for signs of stress or damage when replacing engine mounting rubbers.
