Kohler CH730-3206 23.5HP 747cc V-Twin Engine – 1-1/8in Shaft, Electric Start

Description

The Kohler CH730-3206 horizontal shaft engine solves multi-gun pressure washer repower challenges through high-output V-twin power and an oversized 1-1/8-inch drive shaft. Commercial pressure washing skids operating dual wands at 4000 PSI suffer power loss when fitted with smaller displacement engines. This 747cc 23.5HP Command PRO engine incorporates an oversized 1-1/8-inch horizontal shaft, full-pressure lubrication, and an advanced overhead valve cylinder layout that keeps head temperatures stable under heavy continuous pumping.

An oversized cast-iron cylinder sleeve protects internal tolerances against bore wear, keeping oil consumption low across hundreds of washing hours. The 1-1/8-inch horizontal shaft handles direct ceramic pump couplings and heavy multi-groove belt pulleys without crankshaft deflection. The commercial-grade carburetor meters fuel with precision across varying load demands, preventing engine hesitation when spray guns cycle between open spray and high-pressure bypass.

Engine Architecture of Kohler CH730-3206

• 747cc 23.5HP Commercial OHV V-Twin: Generates 23.5 horsepower to drive multi-gun industrial pressure washing trailers.
• 1-1/8-Inch Keyed Horizontal PTO Shaft: Oversized commercial diameter matches heavy ceramic plunger pumps and drive couplings.
• Full-Pressure Oil Lube with Spin-On Filter: Pumps filtered oil continuously to crankshaft journal inserts and rod bearings.
• 12V Electric Key Starting Motor: Spins the flywheel ring gear with key activation to eliminate manual starting effort.
• Durable Cast-Iron Cylinder Sleeves: Resists bore wear from abrasive dirt, extending engine life in severe commercial service.
• Heavy-Duty Commercial Canister Air Cleaner: Traps fine dust particles across two media layers to preserve cylinder wall compression.

Commercial Utility Stamina & Lifespan

Engineered for continuous commercial operation where equipment failure halts company revenue, this platform delivers reliable mechanical output.

• A rigid aluminum crankcase casting and cast-iron cylinder liners maintain shaft alignment under severe belt drive tension.
• High combustion efficiency lowers fuel burn per jobsite shift, cutting daily operating expenses across commercial fleets.
• Pressure washing contractors and industrial cleaning outfits gain dependable power for high-hour processing machinery.

Chassis Integration & Industrial Fitment

Weighing 94 pounds dry with an industry-standard horizontal base pattern and 1-1/8-inch shaft, this unit drops directly onto multi-gun pressure wash skids, industrial dewatering rigs, and heavy hydraulic power units without deck drilling.

Commercial Warranty & Field Maintenance

• Kohler backs this Command PRO engine with 3-Year commercial warranty coverage on all core components.

Change oil after the initial 20 operating hours, then maintain 100-hour service intervals using 10W-30 oil and a new filter. Tap clean the air filter element weekly on dusty jobsites, and check the spark plug gap at 0.030 inches.
