Product Features

• Structure: A precision-machined, forged steel camshaft with hardened cam lobes and journals. The lobes are engineered with a specific profile to optimize valve timing and lift for efficient combustion.

• Performance: Ensures precise valve timing and lift to maximize engine power, fuel efficiency, and emissions performance. The hardened cam lobes and journals resist wear and fatigue, maintaining accuracy over long service life.

• Design: Directly interchangeable with original equipment camshafts, ensuring a perfect fit with the cylinder head and valve lifters for reliable operation.

Core Function

1. Valve Timing Control: Rotates in sync with the crankshaft to open and close the intake and exhaust valves at precise intervals, ensuring optimal air-fuel mixture intake and exhaust gas expulsion.

2. Lift Profile Management: The cam lobe profile determines how far and how fast each valve opens, optimizing airflow for maximum power and efficiency across the engine’s RPM range.

3. Durability & Precision: The high-strength steel construction and hardened surfaces withstand the repeated impact loads of the valve train, maintaining precise timing and preventing premature wear.

Camshaft 1004878645 WEICHAI – Precision-Engineered OEM Replacement for Peak Engine Performance

When your fleet depends on uninterrupted power delivery, the camshaft sitting at the heart of your WEICHAI engine cannot afford to be anything less than perfect. The Camshaft 1004878645 WEICHAI from METTLEAD Truck Parts delivers factory-grade precision, exceptional wear resistance, and validated timing accuracy — ensuring every valve opens and closes exactly when it should, mile after mile. Sourced directly from our quality-controlled supply chain in China, this camshaft meets the rigorous dimensional and metallurgical standards your WEICHAI engine demands.

Why This WEICHAI Camshaft 1004878645 Outperforms Aftermarket Alternatives

A camshaft does more than spin — it orchestrates the entire combustion cycle. Any deviation in lobe profile, surface hardness, or journal tolerance translates directly into lost power, increased fuel consumption, and premature component failure. Here is what the Camshaft 1004878645 delivers:

• OEM-Matched Lobe Geometry — Cam profiles are ground to WEICHAI’s original specifications, maintaining precise valve lift and duration for optimal air-fuel mixing and combustion efficiency.
• High-Grade Alloy Steel Construction — Forged from chilled cast iron / alloy steel with induction-hardened lobes, achieving surface hardness of HRC 50–60 for extended service life under heavy thermal and mechanical loads.
• Micro-Finished Journal Surfaces — Journal diameters are polished to Ra ≤ 0.4 μm surface roughness, reducing friction and protecting bearings from premature wear.
• Strict Dimensional Tolerancing — Every camshaft undergoes CMM (Coordinate Measuring Machine) inspection to maintain tolerances within ±0.01 mm on critical dimensions.
• Validated Timing Accuracy — Keyway and gear mounting positions are precision-machined to guarantee correct valve timing alignment upon installation.
• Corrosion-Resistant Finish — Anti-rust treatment protects the camshaft during shipping and storage, ensuring it arrives installation-ready.

Application Scenarios – Where This Camshaft Works Hardest

The Camshaft 1004878645 WEICHAI is designed to serve the demanding environments where WEICHAI-powered trucks and machinery operate daily:

• Long-Haul Freight Transport — SINOTRUK HOWO A7 and T7H tractor units equipped with WEICHAI WP12/WP13 engines covering 200,000+ km annually rely on camshaft durability to maintain consistent power output across extended service intervals.
• Construction & Mining Operations — SHACMAN X3000 and SINOTRUK SITRAK dump trucks operating in high-load, stop-start conditions where thermal cycling stresses every engine component to its limit.
• Municipal & Logistics Fleets — FOTON AUMAN and DONGFENG KL series vehicles fitted with WEICHAI WP10 engines performing urban delivery routes that demand reliable cold-start performance and responsive throttle behavior.
• Heavy-Duty Mixer & Special Vehicles — Concrete mixers and crane trucks running WEICHAI engines at sustained high RPM benefit from the hardened lobe surfaces that resist accelerated cam wear.

Whether your fleet runs intercity highways in Africa, construction sites in Southeast Asia, or logistics corridors in the Middle East, this camshaft is built to survive the conditions your trucks face every day.

Frequently Asked Questions – Camshaft 1004878645 WEICHAI

What engines does the Camshaft 1004878645 fit?

This camshaft is designed for WEICHAI WP-series diesel engines (WP10, WP12, WP13) commonly installed in SINOTRUK HOWO, SITRAK, SHACMAN, and FOTON heavy-duty trucks. Always confirm cross-reference compatibility with our technical team before ordering for a specific engine serial number.

How do I verify that this camshaft matches my original OEM part?

The part number 1004878645 is stamped or etched on the original WEICHAI camshaft. We recommend verifying against the OEM number on your existing camshaft or engine parts manual. Our team can also confirm fitment via your engine nameplate data.

What is the expected service life of this camshaft?

Under normal operating conditions with proper lubrication and valve clearance maintenance, this camshaft is engineered to deliver 300,000–500,000 km of service — matching OEM replacement intervals. Actual life depends on oil quality, maintenance schedule, and operating load.

Can lobe wear be detected before failure?

Yes. Early signs of camshaft wear include rough idle, reduced engine power, increased valve train noise, and inconsistent exhaust gas readings. Inspecting lobe surfaces for pitting, scoring, or measurable profile loss during scheduled valve adjustments helps catch wear before catastrophic failure.

Do I need to replace cam bearings and lifters at the same time?

Best practice says yes. Installing a new camshaft against worn bearings or lifters accelerates lobe wear and negates the investment in a new shaft. We supply matching cam bearings, tappets, and timing gear components — ask our sales team for a bundled quotation.

How is the camshaft packaged for international shipping?

Each camshaft is coated with anti-rust preservative, wrapped in VCI (Vapor Corrosion Inhibitor) film, and placed in a foam-cushioned carton or wooden crate based on order size. This packaging protocol prevents surface damage and corrosion during ocean or air freight.
