The BJ-1310-3 Ingersoll Rand OEM Drive Coupler is a Lord BJ-series coupling for Ingersoll Rand portable air compressor platforms. The BJ-1310 is a larger Lord coupling than the BJ-1333 series, serving IR’s mid-range to large portable compressors where higher torque capacity is required.
IR portable compressors in the 300+ CFM class generate substantial torque from their diesel engines, and the BJ-1310 coupling is sized to handle that load while providing effective torsional damping. These machines serve heavy construction, pipeline, and industrial applications where sustained air output is critical for productivity.
The BJ-1310-3 is a direct OEM replacement. Install per IR’s service procedure with proper alignment verification. At this coupling size, alignment precision matters for achieving full service life.
