Description
Overview:
This Ring Set is a genuine Kohler spare for maintaining and restoring compression in Kohler single‐cylinder petrol engines. Supplied under MPN 17 108 07-S, it is engineered for the CH440 and ECH440 families (including CH440TF). The set includes precision rings that seal the combustion chamber and control oil on the cylinder wall, helping the engine start reliably, hold power under load, and run cleaner. Manufactured from durable, heat‐resistant metal alloys, the rings are built to withstand high temperatures and continuous use in site and garden equipment. Correct ring sealing lowers oil consumption, reduces blow‐by, and supports stable idle and throttle response. Designed to Kohler specifications for these engines, it offers a dependable fit during routine maintenance or a top‐end refresh.
