Description
Overview:
The Piston Ring Set Standard for Robin/Subaru EX40 engines is a standard-size ring pack for restoring correct sealing between the piston and cylinder. Made from durable, heat-treated metal alloy with precise profiles, the set maintains compression, limits blow‐by, and controls oil on the cylinder wall. This helps engines start reliably, hold power, and run cleaner with reduced oil consumption. Supplied to match OEM reference 22B-23501-07, it is intended for routine servicing or full overhauls on EX40 units used across construction and garden machinery. A complete set for one piston, it is suitable for workshop rebuilds and on-site maintenance where dependable performance and straightforward fitting are important.
