The 2658546425 Atlas Copco OEM Drive Coupler Element is a coupling element for Atlas Copco portable compressor and drilling platforms. This is the replaceable elastomeric element of a Reich Arcusaflex ACH-series coupling – the flexible component that provides torsional damping between the engine and driven equipment.
The ACH-series Arcusaflex coupling is a larger-format coupling used in Atlas Copco’s heavier portable compressors and drilling support equipment where torque demands exceed the capacity of the smaller ACT-series. Replacing just the element rather than the complete coupling is standard practice when the metal hubs remain in good condition.
During element replacement, inspect both hubs for scoring, corrosion, or bearing surface damage. Clean all mating surfaces before installing the new element. Reassemble per the coupling manufacturer’s instructions and verify alignment before startup.
