Key Features

• Precision Thermal Tolerances: Pistons and compression rings are precision-machined to prevent blow-by and minimize liner scuffing under high thermal loads.
• High-Pressure Fuel Integrity: Fuel injection pumps and injector assemblies are calibrated for precise atomization and optimal combustion efficiency.
• Advanced Sealing Suite: Comprehensive O-ring and gasket assortments utilize high-temperature elastomer compounds resistant to synthetic lube oils and HFO contaminants.
• Valvetrain Longevity: Rotocaps and valve springs ensure uniform heat dissipation and eliminate localized seat wear on exhaust and inlet valves.
• Corrosion Resistance: Bellows and pipe unions feature marine-grade alloy construction resistant to exhaust gas corrosion and vibration fatigue.

Applications

• Main marine propulsion engines for container vessels, bulk carriers, and tankers.
• Auxiliary generator sets (gensets) on offshore drilling rigs and floating production storage and offloading (FPSO) units.
• Heavy-fuel stationary power plants operating on continuous baseload duty cycles.

Marine Engineer Expert’s Guide

• Lube Oil Priming & Pre-lubrication: Prior to cranking the engine after replacing connecting rod bearings (9-2601-003) or pistons (9-2670-1), ensure the auxiliary lube oil pump runs for a minimum of 15 minutes to establish a full oil film across all journal surfaces.
• Torque Sequence Compliance: When mounting cylinder head studs and fuel injection pump housings, adhere strictly to cross-pattern hydraulic tensioning pressures specified in the MaK M32 maintenance manual to prevent crankcase distortion.
• Anti-Polishing Ring Inspection: Ensure the anti-polishing ring (9-1110-108) is correctly seated during liner installation to prevent bore carbon buildup and subsequent piston ring sticking during HFO combustion cycles.

Frequently Asked Questions

Are these spare parts genuine OEM or aftermarket replacements?

Our inventory includes factory-new OEM and certified high-grade replacement spares manufactured strictly to original Caterpillar MaK technical drawings and metallurgical specifications.

Do the spare parts come with classification society certificates?

Yes, material test certificates (MTC 3.1) are available, and third-party inspection by major classification societies (DNV, ABS, LR) can be arranged upon order confirmation.

Can these parts be used in heavy fuel oil (HFO) operating conditions?

All components, including fuel injection assemblies, piston rings, and elastomer seals, are fully rated for continuous operation on HFO up to 700 cStr and modern low-sulfur marine fuels.

What is included in the gasket and O-ring sets?

The package includes all essential Viton and NBR O-rings, copper gaskets, and sealing rings required during a standard cylinder head or top-overhaul maintenance interval.
