23mm Wrist Pin - 82.51mm Bore Size. Includes Wrist Pin, Lock Rings, Piston Rings. 

Kolbenschmidt OE pistons are manufactured to achieve maximum strength combined with low weight, providing reduced emissions, low noise and more efficient fuel and oil consumption.

Kolbenschmidt is an OE supplier and supplies parts to all well-known engine manufacturers - all over the world. For every engine type the most suitable alloy is selected from the KS alloy range, and the most effective piston design is employed. Motor Service always supplies pistons complete with piston rings, piston pins and the associated piston pin circlips.

All original KS pistons are supplied ready for assembly with the corresponding piston rings, piston pin and retainers already fitted, and are carefully packed as complete sets with the exception of the heavier pistons. 

Features and Benefits:

• Cast-in ring carriers of cast iron increase the durability of the first ring groove of diesel pistons many times over. Kolbenschmidt is a leader in the development of Alfin ring-carrier bonding.
• Hard-anodized ring grooves prevent wear and micro welding in pistons for petrol engines.
• Laser-hardened grooves ensure optimum wear resistance and maximum durability for steel pistons.
• KS pistons feature special LofriKS, NanofriKS or graphite coatings on the piston skirt. These reduce friction inside the engine and ensure good emergency running properties. LofriKS coatings are also employed for acoustic reasons. Their use minimizes piston slap noises. NanofriKS is a further development of the tried and tested LofriKS coating, and additionally contains nanoparticles of titanium oxide, to increase the coating’s wear resistance and durability.
• Iron-coated piston skirts (Ferrocoat) guarantee reliable operation when used in aluminium silicon cylinder surfaces (Alusil).
• Specially shaped piston pin bores (Hi-SpeKS) raise the dynamic load capacity of the piston pin bed, thereby increasing the piston’s durability.
