Riding Mower & Zero-Turn Repower Applications
The FR730V-AS40 is offered for riding mower and zero-turn applications using the specified vertical crankshaft. Repower compatibility depends on the complete installation, including the engine mounting pattern, shaft geometry, pulley or PTO clutch position, electrical connections, controls and exhaust clearance.
Use the full engine specification code when comparing replacements. FR730V identifies the engine family; the AS40 specification identifies the configuration offered here. Engines sharing the FR730V name or horsepower rating can have different installation requirements.
Before Ordering
- Record your mower’s complete model and serial numbers and photograph the original engine identification label.
- Confirm the 1-inch crankshaft diameter, 3-5/32-inch shaft length, keyway and retaining-bolt requirements.
- Compare the mounting pattern, PTO clutch or pulley position and belt alignment.
- Check the wiring connections, charging requirements, throttle and choke controls.
- Confirm the muffler arrangement, exhaust clearance and which accessories are included or must be transferred.
- For a different original engine specification, confirm the repower application with the seller or an authorized Kawasaki Engines dealer.
