Description
Overview:
This is a genuine Kohler breather reed (OEM 12 402 02-S) for regulating crankcase pressure on small petrol engines. The thin, spring-steel reed sits in the breather assembly to create the correct vacuum, helping control oil mist, reduce leaks, and maintain smooth running. Built from durable, corrosion‐resistant metal, it is designed for long service life under engine heat and vibration. It is an exact-fit replacement for a wide range of Kohler engines used in garden and construction machinery, including CV14 and CV15. Suitable for ride‐on mowers, zero‐turns, compact equipment, generators, pumps and more, it helps restore reliable ventilation when the original reed is worn, fatigued or bent.
Key Features:
- Genuine Kohler part for assured fit and function (OEM 12 402 02-S)
- Spring‐steel construction for durability and consistent reed action
- Maintains correct crankcase vacuum to reduce oil carry‐over and leaks
- Supports smooth idle, stable performance and emissions control
- Direct replacement part with OEM geometry for proper seating and sealing
- Compatible with many Kohler horizontal and vertical shaft engines (see list)
- Quick, straightforward install with standard hand tools
- Ideal preventive maintenance item to restore breather performance
- Resistant to heat, oil and vibration for long service intervals
- Helps extend engine life by preventing pressure build‐up
Typical Applications:
Used on Kohler‐powered ride‐on mowers, garden tractors, zero‐turns, compact construction equipment, generators, pumps, pressure washers and similar machinery. Replace when experiencing excessive crankcase vapour, oil residue in the airbox, rough idle or after breather service to maintain consistent engine ventilation.
