Product Features

• Structure: A precision-machined hollow cylindrical pin made from high-strength alloy steel, with a hardened and mirror-polished surface for superior wear resistance and fatigue strength.

• Performance: Transmits intense combustion forces from the piston to the connecting rod with minimal friction. Its hollow design optimizes weight without compromising structural integrity, ensuring reliable operation under high loads and temperatures.

• Design: Directly interchangeable with the original equipment pin, ensuring a precise interference fit with the piston and connecting rod small end, eliminating the need for additional adjustments.

Core Function

1. Force Transmission: Converts the linear motion of the piston into rotational motion of the crankshaft by transferring combustion pressure to the connecting rod.

2. Alignment Guidance: Maintains the piston’s correct alignment within the cylinder bore, reducing friction and wear on both the piston and cylinder wall.

3. Durability: The high-quality alloy steel construction resists fatigue and wear, extending the service life of the piston and connecting rod assembly.

Engineered to meet OEM specifications, this piston pin delivers the dimensional accuracy and surface hardness that keep your engines running reliably across thousands of operating hours.

METTLEAD Truck Parts supplies this genuine-spec Piston Pin D05-112-01 directly from our quality-controlled manufacturing base in China — giving procurement managers factory-direct pricing without compromising on the metallurgical integrity your engines demand.

Key Features and Benefits of Piston Pin D05-112-01 SHANGCHAI

Engineered for Extreme Load Conditions

The Piston Pin D05-112-01 SHANGCHAI is manufactured from case-hardened alloy steel, delivering a surface hardness of HRC 58–62 that resists wear under high-frequency oscillating loads. Its precision-ground outer diameter ensures an interference fit tolerance within ±0.005 mm, minimizing piston slap and reducing noise during combustion cycles.

• Superior Fatigue Resistance – Carburized surface treatment creates a hardened outer shell while maintaining a tough, ductile core that absorbs shock loads without cracking.
• Precision Dimensional Control – Each pin undergoes CNC grinding to achieve mirror-finish surface roughness (Ra ≤ 0.4 μm), reducing friction and extending service life.
• Optimized Weight Distribution – Hollow-bore design reduces reciprocating mass, improving engine response and fuel efficiency at high RPM ranges.
• Thermal Stability – Maintains dimensional integrity at operating temperatures exceeding 300°C, preventing seizure in the piston boss bore.
• Direct OEM Replacement – Drop-in fitment for SHANGCHAI D-series engines eliminates the need for machining or modification during installation.

Cost Advantages for Bulk Procurement

As a factory-direct supplier, METTLEAD eliminates intermediary markups. Procurement managers benefit from competitive unit pricing on bulk orders, consistent batch quality, and flexible payment terms that protect your cash flow during large fleet overhaul projects.

Frequently Asked Questions – Piston Pin D05-112-01 SHANGCHAI

What engines does the Piston Pin D05-112-01 SHANGCHAI fit?

This piston pin is designed as a direct replacement for SHANGCHAI D-series diesel engines. It matches the OEM dimensional specifications for the D05 engine platform, ensuring drop-in installation without any machining or bore modification required.

What material is the Piston Pin D05-112-01 made from?

The pin is manufactured from 20CrMnTi carburized alloy steel. This material undergoes carburizing, quenching, and tempering to achieve a hard wear-resistant surface (HRC 58–62) while retaining a tough core (HRC 30–45) that absorbs impact loads without brittle fracture.

How do I verify the correct fitment before ordering?

Cross-reference the part number D05-112-01 with your engine’s original parts catalog. If you provide your engine model number and serial number, our technical team can confirm compatibility before you place your order.

What is the expected service life of this piston pin?

Under normal operating conditions with proper lubrication and within manufacturer-recommended overhaul intervals, this piston pin typically matches OEM service life expectations. Premature wear usually indicates lubrication system issues or overheating rather than component deficiency.

Can I order this piston pin as part of a complete engine rebuild kit?

Yes. METTLEAD supplies complete SHANGCHAI engine overhaul kits including piston pins, pistons, piston rings, cylinder liners, bearings, and gasket sets. Bundling components from a single supplier ensures dimensional compatibility across all mating parts.

What quality inspections does each piston pin undergo?

Every production batch is subjected to hardness testing (Rockwell), outer diameter measurement via CMM (Coordinate Measuring Machine), circularity verification, and surface roughness profiling. We provide inspection certificates with shipment upon request.

Does surface finish quality really affect piston pin performance?

Absolutely. A mirror-ground finish (Ra ≤ 0.4 μm) reduces micro-friction between the pin and piston boss bore, lowers operating temperature at the contact interface, and promotes better oil film retention — all of which directly extend component life and reduce engine noise.
