94.5mm Piston Ring Set OE 23040-4Z900 K6Z1-11-SCO OK6Z1-11-SCO Premium SR CR SR Material for JS K2700 Diesel Engine
The KIA JS K2700 94.5mm Piston Ring Set is manufactured using a premium SR (Steel) compression ring, CR (Cast Iron) scraper ring, and SR (Steel) oil control ring material combination — designated as SR CR SR — to deliver the ideal balance of high-temperature strength, scuff resistance, and long-term dimensional stability required for diesel engine operating conditions.
Produced under ISO/TS16949 quality management protocols, each ring undergoes surface treatment with anti-friction coatings, precision lapping for flatness, and light-tight inspection to verify 100% circumferential contact against the cylinder bore. The OE numbers 23040-4Z900, K6Z1-11-SCO, and OK6Z1-11-SCO are referenced for direct replacement compatibility with the JS K2700 excavator engine.
- SR CR SR Material Matrix Configuration: Top compression ring in hardened Steel (SR) for high-temperature strength, second scraper ring in wear-resistant Cast Iron (CR) for controlled oil film thickness, and 3-piece oil control ring assembly in Spring Steel (SR) for consistent oil return — a proven metallurgical combination for diesel engine durability.
- Anti-Friction Surface Coating Technology: Each compression ring face receives a molybdenum-disulfide or chromium-nitride based anti-scuff coating applied via PVD (Physical Vapor Deposition), reducing initial break-in wear by up to 40% and improving ring-to-bore conformity during the critical first 50 operating hours.
- ISO/TS16949 Certified Production Line: Manufactured in a dedicated diesel engine ring production cell with statistical process control (SPC) monitoring of ring radial wall thickness, axial width, and free gap at multiple checkpoints throughout the machining and finishing stages.
- Light-Tight Circumferential Inspection: Every ring undergoes 100% light-tight testing against a precision-ground gauge cylinder to verify complete peripheral contact, eliminating the risk of localized blow-by caused by ring ovality or uneven lapping.
