PRODUCT DESCRIPTION

Stamped Steel Construction & Precision Sealing Design

This oil sump OE MC300-1009040 is manufactured to exact Yuchai engine specifications, using heavy-gauge stamped steel that provides excellent structural strength and impact resistance. The product features precision-machined sealing flanges that ensure a tight, leak-proof fit with the engine block, eliminating oil leaks and contamination. Its optimized internal design includes baffles to prevent oil starvation under heavy acceleration and cornering, while the integrated drain plug allows for easy oil changes. The 1:1 original dimensional design ensures seamless installation without modification, delivering reliable, long-lasting oil storage performance.

Oil Leaks & Engine Component Damage

Truck operators often face critical issues with substandard oil pans, including thin steel construction prone to impact damage; poor sealing flanges causing persistent oil leaks; and improper baffling leading to oil starvation under load. A faulty oil sump compromises engine lubrication, leads to oil contamination and can result in catastrophic engine failure. By choosing the genuine OE MC300-1009040 oil sump, users can instantly resolve these problems, ensuring consistent oil supply and protecting critical engine components.

OEM Quality & Rigorous Durability Testing

As a key engine protection component, this oil sump complies with Yuchai and Dongfeng’s strict quality standards and has passed comprehensive third-party tests for impact resistance, corrosion performance and sealing integrity. Test data shows the sump maintains structural integrity under heavy impact, resists corrosion from road salt and oil exposure, and meets all applicable engine performance specifications. Each unit undergoes 100% dimensional inspection and leak testing before leaving the factory, guaranteeing complete consistency with original factory parts in performance, durability and fit. Backed by official Yuchai traceability codes, this product ensures 100% authenticity and reliable operation.
