Product Introduction

• Structure: A one-piece, centrifugally cast iron liner with a hardened, wear-resistant inner surface. It features a precision-machined top flange for sealing against the cylinder head, and a bottom locating ring for secure installation in the cylinder block.

• Performance: The high-density cast iron and hardened surface provide exceptional resistance to wear, scuffing, and thermal fatigue, ensuring consistent piston clearance and long service life under extreme combustion pressures.

• Design: A dry-type liner designed for press-fit installation, directly interchangeable with original equipment parts to maintain engine performance and reliability.

Core Function

1. Piston Guidance & Sealing: Provides a smooth, precision-machined surface for piston movement, ensuring optimal combustion chamber sealing and compression pressure.

2. Wear Protection: The hardened inner surface absorbs the friction of piston rings, protecting the cylinder block from direct wear and reducing maintenance costs.

3. Heat Dissipation: Transfers heat from the combustion chamber to the cylinder block’s coolant jackets, helping to regulate engine temperature.

Cylinder Liner 612700010010 for WEICHAI Engines – OEM-Grade Precision, Factory-Direct Pricing

When your fleet depends on WEICHAI-powered trucks running at peak efficiency, every component inside the combustion chamber matters. The Cylinder Liner 612700010010 is engineered to deliver exact OEM fitment, superior heat dissipation, and extended service life — keeping your engines on the road longer and your maintenance costs lower. Sourced directly from METTLEAD Truck Parts, this cylinder liner meets the rigorous standards your procurement team demands: verified quality, competitive pricing, and reliable global delivery.

Why This Cylinder Liner Outperforms Aftermarket Alternatives

Precision-Engineered for WEICHAI WP12/WP13 Platforms

This liner doesn’t just fit — it integrates. Manufactured to OEM dimensional tolerances (±0.01 mm bore accuracy), it ensures optimal piston-to-liner clearance from the first cold start. The result is reduced blow-by, stable oil consumption, and consistent compression across all cylinders.

Advanced Metallurgy for Harsh Operating Conditions

Cast from high-strength centrifugal grey iron with a carefully controlled microstructure, this liner resists thermal fatigue, cavitation erosion, and abrasive wear. The plateau-honed inner surface retains a uniform oil film, reducing friction coefficients and extending overhaul intervals by up to 30% compared to generic replacements.

Direct Cost Savings for Your Procurement Budget

• Factory-direct pricing — eliminates distributor markups by 15–25%
• Batch order flexibility — MOQ as low as 10 pieces for trial orders
• Reduced warranty claims — strict quality control means fewer field failures
• Custom packaging available — white-label options for resellers and workshops

• SHACMAN X3000 / F3000 — mining and construction haulage
• FOTON Auman GTL — express cargo and cold-chain transport
• FAW J6P — heavy-load trunk line operations

Whether your fleet operates across African highway corridors, Southeast Asian plantation roads, or Middle Eastern desert environments, this cylinder liner handles thermal shock, dust intrusion, and sustained high-RPM operation without compromising seal integrity.

OEM/ODM Capability — Tailored to Your Market

White-Label and Custom Packaging

METTLEAD supports distributors and resellers who need branded packaging. We print your logo, part numbers, and barcodes directly on individual boxes and outer cartons — helping you build brand equity in your local market without investing in manufacturing infrastructure.

Strict Quality Control Process

1. Raw material inspection — metallographic analysis and hardness testing on every batch
2. Dimensional verification — CMM (Coordinate Measuring Machine) checks on bore, OD, length, and roundness
3. Surface finish audit — profilometer readings to confirm honing parameters
4. Pressure testing — leak-down tests on O-ring seal grooves
5. Final visual inspection — zero tolerance for casting defects, cracks, or burrs

Every Cylinder Liner 612700010010 that leaves our facility has passed a 5-stage QC gate. We welcome factory visits — come inspect the line yourself.

Frequently Asked Questions — Cylinder Liner 612700010010

Is this cylinder liner an exact match for OEM part number 612700010010?

Yes. This liner is manufactured to the same dimensional and material specifications as the original WEICHAI factory part. It drops directly into WP12/WP13 engine blocks without any machining or modification required.

What is the expected service life of this cylinder liner?

Under normal operating conditions — proper coolant maintenance, clean air filtration, and correct oil viscosity — this liner delivers a reliable service life of 500,000 km or more before requiring inspection or replacement.

How does the plateau honing benefit engine performance?

Plateau honing creates a controlled surface texture with flat peaks and fine valleys. The peaks support the piston rings with minimal friction, while the valleys retain lubricating oil. This reduces wear during cold starts and stabilizes oil consumption across the entire service interval.

Can I order a small trial quantity before committing to bulk?

Absolutely. We offer trial orders starting from 10 pieces so you can verify fitment, finish quality, and customer feedback before scaling up. Lead time for trial orders is typically 3–5 working days from stock.

Does cavitation erosion affect this liner, and how is it prevented?

Cavitation pitting is a known risk in wet-type cylinder liners. This part features an optimized wall thickness and controlled outer-surface roughness that reduces bubble formation in the coolant jacket. Combined with proper SCA (Supplemental Coolant Additive) use, cavitation damage is minimized throughout the liner’s operational life.

What sealing rings are compatible with the lower O-ring grooves?

The three lower seal grooves accept standard WEICHAI-spec nitrile rubber (NBR) O-rings. We recommend replacing all O-rings during liner installation to ensure a leak-free coolant seal. Compatible O-ring kits are available from our WEICHAI Engine Parts catalog.
