Product Features

• Structure: A complete, matched service kit that includes a precision-honed, chrome-plated cylinder liner, a high-strength aluminum alloy piston, a set of three piston rings (compression + oil control), and a hardened alloy steel piston pin with retaining circlips.

• Performance: All components are factory-matched for precise dimensional compatibility, ensuring optimal cylinder compression, minimal oil consumption, and reduced wear. The chrome-plated liner resists corrosion and scuffing, while the piston rings provide reliable sealing even under high loads.

• Design: Directly interchangeable with original equipment components, ensuring a perfect fit and restoring engine performance to factory specifications.

Core Function

1. Combustion Chamber Sealing: The piston and rings create a tight seal within the cylinder liner to maintain compression pressure and prevent gas leakage during combustion.

2. Wear Resistance: The chrome-plated liner and hardened piston pin provide exceptional durability, extending service life in the harsh operating conditions of construction machinery.

3. Restoration of Performance: This kit is designed to rebuild the cylinder-piston assembly, restoring engine power, reducing oil consumption, and improving fuel efficiency.

Features and Benefits

Precision-Engineered Four-Piece Assembly

This component group includes four critical engine parts — piston, piston ring set, piston pin, and cylinder liner — factory-matched as a coordinated unit. Each piece is manufactured to work in harmony, eliminating the guesswork and tolerance stacking that comes with sourcing individual components from multiple suppliers.

• OEM-Grade Dimensional Accuracy: Tolerances held within ±0.01mm ensure perfect cylinder fit and optimal compression sealing from the first start.
• High-Strength Aluminum Alloy Piston: Resists thermal fatigue and mechanical stress under heavy-duty diesel combustion pressures exceeding 150 bar.
• Chrome-Plated Piston Rings: The top compression ring features hard chrome plating for superior wear resistance, reducing oil consumption and maintaining cylinder pressure over 300,000+ km.
• Hardened Piston Pin: Case-hardened and precision-ground to distribute connecting rod forces evenly, preventing premature bushing wear.
• Centrifugally Cast Cylinder Liner: Dense grain structure resists cavitation erosion and provides a stable bore surface throughout the engine’s service life.

Why Procurement Managers Choose This Kit

• Reduced Downtime: Pre-matched components mean faster installation — your technicians spend less time measuring and more time rebuilding.
• Inventory Simplification: One part number replaces four separate SKUs, streamlining your warehouse management.
• Consistent Quality Across Cylinders: Ordering in matched sets ensures uniform performance across all cylinders, preventing imbalanced combustion loads.
• Cost Efficiency: Factory-direct pricing from METTLEAD eliminates middleman markups, saving 15–30% compared to regional distributors.

Frequently Asked Questions

What exactly is included in the Four-Piece Set Component Group C05AL-05AL502+A?

This set includes one piston, one complete piston ring set (three rings), one piston pin with retaining clips, and one cylinder liner. All four components are manufactured and matched as a single unit to ensure proper fit and optimal combustion chamber geometry.

Is this Four-Piece Set Component Group compatible with all SHANGCHAI engine models?

The C05AL-05AL502+A is specifically designed for SHANGCHAI C-series engines with a 126mm bore diameter. If you are unsure whether your engine variant is compatible, provide your engine nameplate data and we will confirm fitment before you order.

How does the matched set differ from purchasing components individually?

Individually sourced components may come from different production batches, leading to slight dimensional variations that accumulate. A matched set guarantees that piston-to-liner clearance, ring end gap, and pin fit are all within the tightest acceptable tolerances — reducing break-in time and extending overhaul intervals.

What is the expected service life of this piston kit?

Under normal heavy-duty operating conditions with proper maintenance (clean air filtration, appropriate oil change intervals, and correct coolant management), this component group typically delivers 250,000–350,000 km before the next overhaul is required.

Can I order this Four-Piece Set Component Group C05AL-05AL502+A in bulk quantities?

Absolutely. METTLEAD supports bulk procurement with tiered pricing. Whether you need 10 sets for a single fleet overhaul or 500+ sets for regional distribution, we scale production to meet your delivery timeline.

How should the cylinder liner be installed to avoid damage?

The liner should be pressed in using a hydraulic liner installer — never hammered. Ensure the engine block bore is clean and free of corrosion. Apply a thin film of clean engine oil to the liner O-ring sealing area before installation to prevent seal nicking.
