Design & Engineering Features
Material & Construction
- High?Strength Cast Aluminum Alloy: Premium alloy with advanced thermal?resistant crown treatment to withstand peak combustion temperatures up to 180 bar.
- Low?Friction Skirt Coating: Graphite/molybdenum composite coating minimizes scuffing and wear, reducing friction losses and extending service life.
- Precision?Machined Combustion Bowl: Optimized geometry (55.21 mm diameter, 22 mm depth) promotes superior air?fuel mixing, reduces emissions, and controls combustion noise.
- Floating Piston Pin: 38.10 mm (1.500 in) diameter pin with spiral lock/snap?ring retention for minimal friction and secure connection to the connecting rod.
- No Standard Cooling Gallery: Base design (225?5437) balances weight, cost, and performance for mid?range power applications.
Ring Pack Configuration (3?Ring System)
- Top Compression Ring: Taper?faced, molybdenum?coated (T 3.5 Mo P) – primary cylinder pressure sealing, wear?resistant.
- Second Compression Ring: Scraper design (M 2.5 IFU P) – secondary sealing and enhanced oil control.
- Oil Control Ring: Segmented with expander spring (DSF 3.5 Cr P) – efficient oil return to crankcase, preventing oil consumption.

Installation & Service Guidelines
Pre?Installation Preparation
- Inspect cylinder liners for scoring, wear, or cracks; replace if out of tolerance.
- Clean all components thoroughly to remove debris and contaminants.
- Heat piston to 60–80°C for easy floating pin installation (avoid overheating to prevent material damage).
Installation Requirements
- Verify ring end gaps and ensure correct orientation (top ring marked “TOP” must face upward).
- Follow Caterpillar torque specifications for connecting rod bolts and cylinder head fasteners to prevent misalignment and premature wear.
- Use only genuine Cat or approved lubricants during assembly.
Maintenance Recommendations
- Use Cat DEO CJ?4 or equivalent high?quality engine oil.
- Perform regular oil and air filter changes to prevent abrasive wear.
- Monitor engine blow?by, oil consumption, and compression; replace piston rings during in?frame overhaul if issues are detected.
