⚠️ CRITICAL FITMENT NOTE: These piston rings are designed for 69.85mm (2.750") STANDARD BORE cylinders only. DO NOT USE with oversized cylinders (.010", .020", .030", .040", .060") unless ordering the matching oversize variant part numbers listed above. Always verify cylinder bore measurement with precision micrometer before installation. Improper ring-to-bore matching can cause catastrophic engine failure, loss of compression, or excessive oil consumption.

📦 WHAT'S INCLUDED

1x Piston Ring Set for ONE CYLINDER (2 Compression Rings + 2 Oil Rings) [[3]][[23]]
Protective anti-corrosion packaging for safe global shipping
Installation guidance: Ring gap orientation, torque specs reference (digital)
Note: Order quantity = number of cylinders in your engine (e.g., 4-cylinder engine = order 4 sets)

🔧 PROFESSIONAL INSTALLATION TIPS

Always measure cylinder bore with precision micrometer; confirm 69.85mm ± tolerance before installing STD rings
Stagger ring end gaps per Caterpillar service manual specifications (typically 120° apart for 4-ring sets)
Use proper ring compressor tool; never force rings into cylinder bore
FERROX coating aids break-in – follow recommended break-in procedure: varied RPM, avoid sustained high load for first 50 hours
Replace all rings in an engine simultaneously for balanced compression and longevity
Pair with new piston pins, bearings, and gaskets for complete overhaul reliability

Pro Mechanic Tip: Vintage Caterpillar engines like the D2/D4/D315 benefit from thorough cleaning of ring grooves before installing new rings. Use a ring groove cleaning tool to remove carbon deposits – this ensures proper ring seating and optimal compression restoration. Always torque cylinder head bolts to spec in the correct sequence for even sealing.
