FAQ

This kit is designed for John Deere models L110, LT160, LX266, and GT225. It is specifically engineered for engines using Kohler Command Pro series components, including CV13S, CV16S, CV490, CV491, CV492, and CV493.
This kit replaces John Deere OEM part numbers GY20661 and M145944. It also covers Kohler engine components 12 083 10-S and 12 083 16.
You should consider a tune-up if you notice a loss of engine power, rough idling, excessive black smoke from the exhaust, or if the mower struggles to start. If the air filter appears dark, clogged with debris, or the oil filter housing shows signs of leaking, these parts should be replaced immediately to prevent engine damage.
Installation is straightforward and typically takes about 30 to 45 minutes. You will need a basic socket set for the oil drain plug, an oil filter wrench to remove the old filter, a clean drain pan, and a rag to wipe up any residual oil. Ensure the engine is cool before beginning the oil change.
Replacing both filters simultaneously ensures that your engine is receiving clean, unrestricted airflow and properly filtered oil. Using old, saturated filters can lead to increased engine temperatures and premature wear on internal components, which significantly shortens the lifespan of your Kohler Command Pro engine.
Before spinning on the new oil filter, apply a light film of fresh engine oil to the rubber gasket on the top of the new filter. This ensures a proper seal and makes the filter much easier to remove during your next scheduled maintenance.
