CRX680 679cc V-Twin Engine — 1" Shaft, 20A Electric Start
$1,592.00
This is a first-generation CRX680 bare motor with 20-amp charging system and electric start, built for a wide range of commercial equipment, displacing 679cc with a 1" crankshaft. Supplied as an engine only — no pump, frame, or plumbing — for builders replacing a worn engine or assembling a custom pressure washing rig from the ground up.
Engine choice is the foundation of any build. CRX engines deliver commercial-grade performance at a lower cost than the premium alternatives, which makes them a practical choice for builders watching margins without wanting to compromise on capability. A charging system matters if your rig runs 12V accessories — reels, pumps, hot boxes, or lighting — since it keeps batteries topped off through the workday instead of leaving you dead at the end of a shift.
Before ordering a replacement engine, confirm shaft diameter, shaft length, keyway, and mounting bolt pattern against your existing setup. Grime Task Force stocks the engines and the service parts that go with them, so a rebuild doesn't turn into a parts hunt.
