Reliable Engine Connection Components for Industrial Machinery Maintenance
Ensure your heavy equipment operates with minimal vibration and maximum efficiency. The 315-46T (also searched as 31546T) engine coupling is a critical component for Caterpillar machine models, designed to absorb shock and maintain precise alignment between the engine and driven components.
Whether you are performing an engine overhaul or routine maintenance, selecting an OEM-standard replacement part is vital for equipment longevity. Our 315-46T parts are built to withstand high torque and extreme temperature fluctuations common in construction environments.

Common symptoms of a failing 315-46T coupling include excessive engine vibration, unusual noise during startup, and visible cracks in the mounting rubber. If you detect these signs, immediate replacement is necessary to protect your crankshaft and transmission.
A: This is often caused by the degradation of the 315-46T engine coupling rubber. When the internal elastomer loses its elasticity or cracks, it no longer absorbs engine torque pulses. We recommend a full inspection of the 31546T mounting area.
A: While the 315-46T is common in specific C-series engines, always verify your engine serial number. Using the wrong coupling can lead to shaft misalignment.
