How do I install the Buckbock ignition coil and what should I expect?

Installation follows the same steps as the factory coil: disconnect the battery, remove the engine shroud, unbolt the old coil, and transfer any mounting brackets or condenser if required. A multimeter or spark tester can confirm correct operation after installation.

• Direct-fit mounting and factory-style electrical terminals for easy swap-in replacement.
• Standard installation tools: wrench set, screwdrivers, and optionally a spark tester.
• If needed, transfer the condenser or mounting plate from the old coil for proper grounding and spacing.

What parts and engine numbers should I confirm before ordering?

Always compare the part number stamped on your old coil or check your engine’s service manual. Matching the OEM references and engine model ensures you receive the correct replacement item.

• Confirm Kohler part numbers like 12-584-04-S, 12-584-01-S or similar stamped markings.
• Verify your engine model (e.g., CV11, CV15S, CH14S) and the equipment model (John Deere L110, LT155, etc.).
• Cross-reference any alternative part numbers listed in your machine’s parts diagram or sticker.
