Product Features

• Structure: A complete set including two compression rings (top ring: chrome-plated for wear resistance; second ring: taper-faced for improved oil control) and one three-piece oil control ring (expander spring + two scraper rails).

• Performance: The top ring seals combustion pressure, the second ring enhances sealing and scrapes excess oil, and the oil control ring regulates oil film thickness on the cylinder wall to minimize oil consumption. The chrome plating and spring design ensure long-term reliability under high temperatures and pressures.

• Design: Directly interchangeable with original equipment ring sets, ensuring precise fit with the piston groove and cylinder liner for optimal sealing performance.

Core Function

1. Combustion Sealing: Maintains cylinder compression pressure by preventing gas leakage between the piston and cylinder liner during combustion.

2. Oil Control: Scrapes excess oil from the cylinder wall to reduce oil consumption and prevent oil from entering the combustion chamber.

3. Heat Transfer: Transfers heat from the piston to the cylinder liner, helping to keep piston temperatures within the optimal range.

Piston Ring D05-002.107.108 SHANGCHAI – Premium Engine Piston Ring for Heavy-Duty Performance

When your SHANGCHAI engine demands precision sealing and long-lasting durability, the Piston Ring D05-002.107.108 SHANGCHAI delivers exactly that. Engineered to meet OEM specifications, this piston ring set maintains optimal compression, controls oil consumption, and transfers heat efficiently from the piston to the cylinder wall. METTLEAD Truck Parts supplies this critical engine component at factory-direct pricing with strict quality control — so your fleet stays on the road and your maintenance costs stay down.

Key Features and Benefits of Piston Ring D05-002.107.108

Precision-Engineered Sealing Performance

The Piston Ring D05-002.107.108 SHANGCHAI is manufactured with tight dimensional tolerances to ensure a gas-tight seal between the piston and cylinder bore. This precision engineering minimizes blow-by gases, preserves combustion pressure, and maximizes power output across the engine’s operating range.

Superior Material Composition

Constructed from high-grade alloy cast iron with a chrome-plated compression ring and nitrided oil ring, this piston ring set resists wear, corrosion, and thermal fatigue. The advanced surface treatment reduces friction coefficients and extends service intervals significantly compared to standard aftermarket alternatives.

Optimized Oil Control

The oil ring component of this set features a precisely engineered spring-loaded design that scrapes excess lubricant from the cylinder wall while maintaining a thin, uniform oil film. This balance prevents excessive oil consumption without starving the cylinder of necessary lubrication.

Thermal Management

Acting as a thermal bridge, the D05-002.107.108 piston ring transfers approximately 30% of combustion heat from the piston crown to the cooled cylinder wall. This heat dissipation protects the piston from thermal overload and prevents ring sticking or scuffing under heavy loads.

Direct Cost Savings

• Factory-direct pricing eliminates middleman markups
• Extended service life reduces replacement frequency
• Lower oil consumption cuts lubricant costs over time
• Maintained compression efficiency preserves fuel economy

Frequently Asked Questions – Piston Ring D05-002.107.108 SHANGCHAI

What symptoms indicate that the D05-002.107.108 piston ring needs replacement?

Common signs include increased oil consumption, blue or gray exhaust smoke under load, reduced compression pressure readings across cylinders, and noticeable power loss. If a compression test reveals more than 15% variation between cylinders or readings below the SHANGCHAI service manual threshold, the piston rings likely require replacement.

Is this piston ring set compatible with oversized pistons?

The D05-002.107.108 is manufactured to standard bore dimensions. If your engine has been rebored to an oversize specification, please provide the exact bore diameter when requesting a quote so we can confirm compatibility or source the correct oversize ring set for your application.

How does the chrome-plated top ring improve durability compared to uncoated alternatives?

The chrome plating on the top compression ring provides a surface hardness of HV 800–1000, which resists abrasive wear from combustion particles and maintains the ring face profile over extended service intervals. Chrome-plated rings typically last 2–3 times longer than uncoated cast iron rings in high-load diesel applications.

What is the recommended break-in procedure for new piston rings?

After installation, operate the engine at varied loads (50–75% capacity) for the first 50 operating hours. Avoid sustained full-load operation during this period. Change the engine oil and filter at the end of the break-in period to remove metallic particles generated during ring seating. This procedure ensures proper ring-to-bore conformity and optimal sealing.

Can I order a single-cylinder ring set or must I purchase a full engine set?

We supply the Piston Ring D05-002.107.108 both as individual cylinder sets and as complete engine sets. However, for optimal engine balance and performance, we recommend replacing all cylinder ring sets simultaneously during a major overhaul.

How should I store piston rings before installation?

Store the rings in their original packaging in a dry, temperature-stable environment. Avoid stacking heavy items on top of ring boxes, as deformation can alter the ring’s free gap and elasticity. Apply a light coat of clean engine oil before installation to prevent initial dry-start scuffing.
