154-64283 Grimmer OEM Drive Coupler

The 154-64283 Grimmer-Schmidt OEM Drive Coupler is a coupling for Grimmer-Schmidt portable air compressors. Grimmer-Schmidt manufactures diesel-driven portable rotary screw compressors used in construction, sandblasting, painting, and general industrial field service applications.

The drive coupler in Grimmer-Schmidt compressors connects the engine to the airend through a torsionally flexible elastomeric element. This coupling absorbs the vibration generated by the diesel engine while transmitting smooth torque to the compressor. Grimmer-Schmidt machines are known for their straightforward, serviceable designs, and coupler replacement is a standard maintenance item during the machine’s service life.

The 154-64283 is a direct factory replacement. During installation, inspect both hubs for wear, clean all shaft surfaces, and verify alignment per the compressor service manual. Confirm smooth operation and acceptable vibration levels after startup before returning the machine to service.
