YAMAKATO Ignition Coil for Kohler CV/CH Engines — 12 584 04-S Direct-Fit Kit with Gauge & Spark Plug

YAMAKATO 12 584 04-S is a direct-fit ignition coil assembly engineered to replace Kohler OEM 12 584 04-series coils for select CV, CH and CV-series engines and compatible garden tractors.

This high-voltage coil kit from YAMAKATO is built to restore consistent spark delivery on small engines that use Kohler CV and CH family magnetos. It ships with the coil, a 0.3mm feeler gauge and a replacement spark plug so you can set the air gap and test ignition quickly. The part targets specific Kohler part numbers and many common mower and tractor models from Toro, John Deere and Craftsman — but always cross-check part numbers and images before ordering.

Which engines and part numbers does this coil replace?

The YAMAKATO 12 584 04-S is manufactured to match the fit and wiring of Kohler coils identified by numbers in the 12 584 04 / 12 584 01 family. It fits selected CH and CV-series Kohler engines used on many residential and commercial mowing units.

• Replaces Kohler: 12 584 04, 12 584 04-S, 12 584 01-S and related KH prefixed numbers.
• Crosses with Stens: 055-229 and 055-465 magneto assemblies where applicable.
• Matches coils used on specific CV/CH models like CH11, CH13, CH14, CV13S, CV15S, CV460S and CV490S.

Will this coil work on my mower or tractor model?

The coil fits many models from Toro, John Deere and Craftsman but compatibility depends on the engine’s exact part number and magneto mounting. If your equipment lists any of the referenced Kohler part numbers, this YAMAKATO coil is likely suitable; if not, compare diagrams and pictures before installing.

• Toro models often covered: 72052, 72072, 72200 and similar riding mowers.
• John Deere units commonly compatible: L110, LT133, LT155, LT160, LX173 and several STX/SST series.
• Some Craftsman part numbers such as 917.273642 and 917.289031 may use the same coil design.

What’s included and how do I set it up?

The kit contains the coil assembly plus a 0.3mm feeler gauge and a replacement spark plug to help you establish the correct air gap. Installation is typical for small-engine ignition coils but requires following safe shutdown and grounding procedures; check torque specs and routing before starting the engine.

• Package: 1 x 12 584 01-S coil, 1 x 0.3mm feeler gauge, 1 x spark plug.
• Use the supplied feeler gauge to set the coil-to-flywheel air gap per engine manual.
• Verify wiring polarity and secure mount bolts; test for spark before reassembling covers.
