Perkins 1106 C7.1 Diesel T417298 Piston Kit Replacement Set for Excavator Engine

This T417298 piston kit is precision-engineered for Perkins 1106 and C7.1 series diesel engines widely used in excavators and heavy-duty construction machinery. Each kit provides a complete piston replacement solution, manufactured to meet or exceed OEM specifications for dependable engine overhaul performance.

• Complete Replacement Kit: Each set includes pistons, piston rings, piston pins, and retaining clips — everything required for a thorough cylinder overhaul on Perkins 1106 and C7.1 engines.
• OEM Specification Compliance: Manufactured to precise dimensional tolerances matching original Perkins T417298 pistons, ensuring correct compression ratio, piston-to-wall clearance, and ring end gaps.
• Aluminum Alloy Construction: Lightweight yet durable aluminum alloy pistons with optimized skirt profiles reduce friction and improve thermal conductivity for consistent engine performance under load.
• Precision-Machined Ring Grooves: CNC-machined ring lands with controlled clearances ensure proper ring seating and effective combustion gas sealing throughout the service interval.
• Heavy-Duty Wrist Pins: Case-hardened steel piston pins with precision-ground surfaces provide reliable load transfer between piston and connecting rod under high cylinder pressures.

This piston kit fits Perkins 1106 and C7.1 diesel engines commonly found in CAT excavators, wheel loaders, backhoe loaders, and other heavy equipment platforms. It is suitable for both engine overhaul and cylinder repair projects.

1. Inspect cylinder bores for wear, scoring, and out-of-round condition before ordering replacement pistons
2. Measure piston-to-cylinder clearance according to engine service manual specifications
3. Check ring end gaps and adjust as needed before installation
4. Use proper piston ring compressor tool during assembly to prevent ring damage
5. Apply clean engine oil to piston skirts and rings before installation
6. Follow manufacturer torque specifications for connecting rod bolts

Each piston is individually wrapped with anti-corrosion protective paper and foam cushioning. Complete kits are packed in export-grade double-wall cartons with compartment dividers to prevent component contact and transit damage.
