The 185DR Schmidt OEM Drive Coupler is an OEM coupling for diesel-driven portable air compressor platforms. This coupling provides the flexible engine-to-airend connection in compact portable compressors used across construction and general industrial field service.
Compact portable compressors in the 185 CFM class are the most widely deployed towable units in the rental and contractor market. The drive coupler absorbs constant torsional load from the diesel engine while compensating for minor shaft misalignment. A worn coupler shows up as increased frame vibration and unstable air delivery.
The 185DR is a direct replacement for equipment originally fitted with this coupling. Install per the compressor service manual with proper alignment verification.
Available from Stark Industrial Products with same-day shipping on in-stock parts.
