Which Kohler engines will this stator and regulator rectifier fit?

The zozoye 237878-S kit is made to fit many Kohler single- and twin-cylinder engines across K, CH and CV model lines. Check your engine model and service manual to confirm compatibility before ordering.

• Compatible with K482, K532, K582, K161, K181, K241
• Also fits K301–K341 series and CH11–CH15, CH18–CH25 ranges
• Works with CV11–CV15, CV18–CV22 and CH25S models
• Matches OEM reference 237878-S for direct replacement

How does this kit improve charging and electrical performance?

The matched stator and regulator rectifier ensure the alternator produces the correct AC output and that the rectifier converts and regulates it into stable DC for the battery and accessories. Replacing worn components removes voltage inconsistencies that cause dim lights, weak starts, or blown fuses.

• Stator generates consistent alternator output at rated 15/20 amps
• Regulator rectifier converts AC to smoothed DC and limits voltage spikes
• Reduces battery drain and electrical noise that affect accessories
• OEM-equivalent design for straightforward installation and alignment

What’s included and what should I expect during installation?

The kit ships complete with one stator and one regulator rectifier so you have both parts needed to restore the charging system. Installation typically requires basic hand tools and mechanical experience; follow Kohler service instructions for rotor removal, stator seating, wiring connections and torque specs.

• Included: 1x 15/20 amp stator and 1x regulator rectifier
• Tools: socket set, screwdrivers, flywheel puller (if required)
• Wiring: match connector colors and secure grounds per manual
• Tip: inspect flywheel key and rotor for wear while servicing

What materials and quality features does the zozoye unit offer?

Designed as an OEM-quality replacement, this kit uses durable insulation, corrosion-resistant terminals, and robust magnet wire to withstand vibration and heat from prolonged engine use. It’s intended for long service life with routine maintenance.

• High-grade copper windings and protective varnish on the stator
• Heat-tolerant regulator components and sealed connections
• Corrosion-resistant mounting and terminal hardware
• Backed by zozoye after-sales support for part fit and function

Who is this for This zozoye 237878-S kit is for technicians, fleet managers and home mechanics who need a dependable electrical replacement for Kohler K-, CH- and CV-series engines. It suits anyone rebuilding engines, repairing charging problems, or upgrading worn alternator components to OEM-equivalent quality for lawn, garden, utility and light commercial equipment.
