315*130*100 Lower Oil Pan Assembly | Construction Machinery & Heavy Truck Diesel

High-quality lower oil pan assembly for heavy-duty construction machinery and truck diesel engines. OEM standard engine bottom protection & oil storage replacement parts, factory direct wholesale, flexible MOQ, fast lead time, ISO & CE certified for global aftermarket repair.

The lower oil pan assembly is a core bottom structural component of diesel engines, widely installed on construction machinery and heavy-duty truck engines. It serves two critical functions: storing engine lubricating oil and protecting internal engine bottom parts from external impact, dust and sediment invasion. This oil pan assembly adopts high-strength stamped steel or cast iron material, processed through integral forming, precision edge trimming and sealing surface finishing. It features strong impact resistance, anti-deformation performance and excellent oil sealing ability. Under harsh working environments of construction sites and long-term heavy-load operation, it effectively prevents oil leakage, bottom shell damage and engine oil contamination. Manufactured strictly in accordance with OEM dimensional and technical standards, the lower oil pan assembly achieves 100% installation interchangeability, acting as a perfect direct replacement for old or damaged original parts in engine overhaul and daily maintenance.

Each lower oil pan assembly is cleaned, polished and treated with anti-rust oil before packaging. Independent shockproof foam and thick inner cartons are used to prevent extrusion, deformation, scratch and oxidation during long-distance sea and air transportation. Outer layers adopt thickened drop-proof export cartons. Pallet packaging is available for bulk orders. Standard neutral export packaging is provided, and custom branded logo packaging is supported for large-scale wholesale orders.

We support flexible order quantities to meet diverse customer procurement needs. 1–3 pieces sample trial orders are acceptable for quality inspection and equipment compatibility verification. The standard wholesale MOQ is 30 pieces. Mixed container loading with other engine parts and construction machinery spare parts is allowed to reduce comprehensive procurement and logistics costs.

In-stock lower oil pan assemblies can be shipped within 3–7 working days after deposit confirmation. Bulk mass-production orders take 15–25 working days according to actual order quantity. Priority rush delivery is available for urgent project orders upon advance negotiation.

All lower oil pan assemblies pass strict factory tests including dimensional inspection, flatness detection, sealing test and surface quality inspection. Our factory holds ISO9001 quality management system certification and CE certification. All products comply with international mechanical industry standards and support smooth cross-border customs clearance for global clients.
