Fitment & Compatibility

 Applicable Engine Models: Weichai Power WP12 series heavy-duty diesel engines (double-check your engine serial number first to avoid fit issues)

 Compatible Vehicle Models: Fits trucks, buses, construction machinery with WP12 engines (SHACMAN, SINOTRUK and other heavy-duty brands included)

 OE/OEM Reference Number: 612600150367 (direct swap for Weichai's original part-zero mods needed)

 Interchangeability: Swaps straight in for your WP12's stock pan. Won't fit WP10/WP13 or non-Weichai engines unless you rebuild the whole engine

 Engine Serial Number Matching Service: Send us your engine serial number, confirm fitment in minutes

Technical Specifications

  Material: Thickened cold-rolled steel (impact-resistant) + reinforced aluminum alloy brackets (rust-proof)

  Dimensions: Custom-made for WP12 engine blocks (ask for size drawings if you need to verify)

  Weight: 15.2 kg

  Oil Capacity: Built for WP12's full 28L oil load (keeps lubrication steady under max stress)

  Working Temperature Range: -40°C to 200°C (handles Siberian winters and desert summers easily)

  Sealing Pressure Resistance: Holds 0.8 MPa oil pressure without a single drop of leakage

  Key Tolerance: Mounting hole position ±0.03 mm (guarantees a tight, leak-free fit every time)

Material Grade & Source: Premium 1.5mm thick cold-rolled steel from trusted mills; aluminum alloy brackets for corrosion resistance. Material certificates available on request

Key Processes & Production Capacity (Combined):

Precision stamping: High-pressure machines shape steel into pan form-uniform thickness, no weak spots

Reinforced bracket welding: Robots weld aluminum brackets to high-stress areas (stops deformation from engine vibration)

Sealing groove machining: Cuts precision grooves for OEM gaskets (no leaks at the engine joint)

Anti-corrosion coating: Electrostatic spray on inner/outer surfaces (fights rust, oil sludge, chemical damage)

Leak pressure testing: 100% of units tested at 0.8 MPa air pressure (catches micro-leaks before factory shipping)Our factory runs automated stamping lines, welding robots, coating workshops. We handle 1,000+ unit bulk orders monthly, tweak designs for custom jobs-just tell us what you need

Quality Grade: OEM quality (matches every Weichai original part standard-no shortcuts)

Inspection Items:

Dimensional check: Verifies mounting holes and pan shape fit WP12 specs

Leak test: 0.8 MPa air pressure to spot the tiniest leaks

Coating adhesion test: Ensures anti-corrosion layer stays put when hot

Vibration test: Simulates 10,000 hours of engine shake (checks for weld failure or deformation)

Load-bearing test: Supports 5x its weight without bending (resists road debris impacts)

Certification & Traceability (Combined): IATF16949 and ISO9001 certified-strict quality control at every step. Every batch has a unique serial number, traceable to steel source, production date, inspection records. Total transparency, no hidden details

Average Service Life: Over 600,000 km or 8 years with normal use-twice as long as thin aftermarket pans that fail at 300,000 km

Performance Advantages: 50% more impact-resistant than standard steel; thickened design stops deformation; high-temp coating fights sludge; precision sealing eliminates leaks

Heavy-Duty Performance: Thrives in tough conditions-off-road construction, mining haul roads, long-haul highway runs. No leaks, no rust, no bending-even with constant vibration and heavy loads

Common Issues with Cheap Oil Pans: Thin steel bends from road debris (leaks everywhere);

                                    poor sealing causes oil loss and engine overheating; low-quality coatings rust fast (clogs oil filters with sludge)

Our Improvements: Thickened steel + reinforced brackets resist damage; precision grooves + OEM gaskets stop leaks;

                                   high-temp coating prevents rust and sludge buildup

Cost Savings for You: No more frequent pan replacements-this one lasts twice as long.

                                   Skip costly engine repairs from leaks or sludge, keep your fleet rolling instead of sitting idle

Packaging Options: Standard neutral cartons (small samples); custom branded boxes (bulk wholesale);

heavy-duty wooden crates (sea shipping-shockproof, moisture-proof, pans arrive perfect)

Anti-Rust & Shock Treatment: Every pan gets plastic film wrap + EPE foam padding; inner surfaces sprayed with rust inhibitor for long-term storage.

Labeling: Stamped with part number, batch number, production date, weight; barcode included for easy inventory tracking .

Stock Status: Top seller for WP12 engines-5,000+ units in stock year-round (order today, ship tomorrow)

Replenishment Cycle: 7–10 days for bulk orders if stock runs low (our lines ramp up fast to meet demand)

Minimum Order Quantity (MOQ): 1 piece for samples; wholesale MOQ negotiable (better prices for 100+ unit orders)

Technical Matching Support: Send us your engine serial number or vehicle model-confirm fitment in minutes (no guesswork, no wrong orders)

Installation Guidance: Free OEM drawings + video tutorials; our tech team answers gasket and torque spec questions for free

Warranty Policy: 12-month warranty. If the pan leaks or deforms due to manufacturing defects , we send a free replacement-no hassle, no fine print

Custom Processing: We build oil pans from your drawings or samples-tweak steel thickness, add drain holes, install heat insulation, change coating colors 

Small Batch Prototyping & Customizable Items (Combined): Prototype orders (min. 10 pieces) available for new engine models or specialized uses (marine, generator sets). Customize steel thickness, bracket design, coating type, drain plug position, oil capacity-just share your specs

Domestic Heavy-Duty Fleet Market: Supplied to SHACMAN long-haul fleets-our pans run 800,000+ km on WP12 engines with zero leaks or failures

Southeast Asian Construction Market: Used on WP12-powered excavators in Indonesia-thickened design resists rock impacts (local crews swear by them)

Typical Use Scenarios: Long-haul trucks, construction excavators/loaders, mining dump trucks, generator sets-any equipment with a Weichai WP12 engine

1.Can you confirm fitment with my engine's serial number?

   You bet. Send us your Weichai WP12 serial number, verify within 24 hours.

2.What's different between your pan and cheap aftermarket ones?

   Ours uses thickened steel, reinforced brackets, precision sealing-lasts twice as long. Cheap pans bend and leak, costing you engine repairs.

3.Does this pan come with a gasket? 

   Yes. Every pan includes an OEM-grade rubber gasket for a leak-free seal.

4.What payment methods do you accept?

   T/T, L/C, Western Union, VTB.
