Product Features

• Structure: Cast from high-strength, wear-resistant ductile iron, with precision-machined sealing surfaces and bolt holes for a secure fit. It features integrated mounting points for alignment with the oil pump housing.

• Performance: Resists high oil pressures and temperatures up to 150°C, maintaining a leak-free seal even under heavy engine loads. The ductile iron construction ensures durability and resistance to deformation.

• Design: Factory-calibrated to match the original pump’s internal tolerances, ensuring perfect alignment of the pump gears and optimal oil flow.

Core Function

• Seals the oil pump’s internal components, maintaining pressure and preventing oil leaks from the pump housing.

• Provides structural support for the pump’s internal gears, ensuring precise alignment and efficient oil pumping.

• Protects the pump’s internal components from contamination, extending the service life of the oil pump.A

Oil Pump Cover 200V05103-5036 for SINOTRUK MC Engine — Factory Direct Supply

When your SINOTRUK MC-series engine demands precise oil pressure regulation and leak-free sealing, the Oil Pump Cover 200V05103-5036 delivers exactly that. Engineered to OEM dimensional tolerances, this cover safeguards the oil pump assembly against pressure loss, contamination ingress, and premature wear — keeping your fleet on the road and your maintenance costs under control.

METTLEAD Truck Parts supplies this genuine-equivalent oil pump cover directly from our quality-controlled production line in China, offering procurement managers the shortest lead times, competitive factory pricing, and the technical confidence that comes from a specialist in Chinese heavy-duty truck components.

Key Functions and Buyer Benefits

Precision Sealing Performance

The 200V05103-5036 oil pump cover is machined to tight flatness tolerances (≤0.05 mm), ensuring a uniform gasket contact surface that prevents oil seepage even under sustained operating pressures of up to 0.6 MPa. This translates directly into reduced unscheduled downtime and lower fluid top-up costs across your fleet.

High-Grade Material Durability

Cast from aluminum alloy with T6 heat treatment, this cover resists thermal cycling fatigue and corrosion from acidic oil degradation byproducts. Field data from comparable OEM components indicates a service life exceeding 300,000 km under standard operating conditions.

Drop-In OEM Compatibility

Bolt pattern, port geometry, and locating dowel positions replicate the original SINOTRUK specification. No adapter plates, no re-drilling — your technicians install it in the same time window as the factory part, minimizing vehicle-off-road hours.

Cost Efficiency Without Compromise

By sourcing directly from METTLEAD’s production facility, you eliminate multi-tier distributor markups. Bulk procurement programs offer additional volume-tiered pricing, helping you protect margins on fleet maintenance contracts.

Technical Specifications

Application Scenarios

Fleet Maintenance Programs

Transport companies operating SINOTRUK SITRAK C7H and HOWO T7H tractor units equipped with MC11/MC13 engines rely on the 200V05103-5036 oil pump cover during scheduled 100,000 km engine service intervals. Replacing the cover proactively during oil pump inspections prevents micro-crack propagation that could lead to catastrophic oil pressure loss on long-haul routes.

Engine Overhaul Workshops

Authorized and independent repair facilities performing complete MC-engine rebuilds specify this cover to restore factory sealing integrity. Its precise dimensional match ensures the rebuilt oil pump assembly meets OEM pressure-flow curves without shimming or sealant compensation.

Export Distributors Serving Africa, Southeast Asia, and CIS Markets

Distributors stocking SINOTRUK wear parts for high-growth markets benefit from METTLEAD’s white-label packaging option, allowing them to build their own brand equity while offering a factory-quality component at a competitive landed cost.

OEM/ODM Capability

• White-Label Packaging: Your brand name, logo, and part numbering system printed on boxes and labels — ready for your distribution channel.
• Custom Packaging: Tailored carton dimensions, anti-corrosion VCI wrapping, and multilingual instruction inserts to meet destination-market regulations.
• Strict Quality Control: Each oil pump cover undergoes CMM dimensional inspection, surface roughness verification (Ra ≤ 1.6 μm), and pressure-decay leak testing before dispatch.
• Sample Approval Process: Pre-production samples shipped within 5 days for your engineering team’s validation before bulk commitment.
• Factory Visits Welcome: METTLEAD invites procurement teams to inspect production lines, QC labs, and warehousing facilities on-site in China.

Frequently Asked Questions

Is the Oil Pump Cover 200V05103-5036 identical in dimensions to the original SINOTRUK part?

Yes. The cover is reverse-engineered and validated against OEM blueprints. Bolt hole spacing, dowel pin positions, and gasket groove depth match the factory specification within ±0.02 mm, ensuring a direct bolt-on fit with no modifications required.

What engine models does this oil pump cover fit?

The 200V05103-5036 oil pump cover is designed for SINOTRUK MC11 and MC13 engines — the MAN-technology powertrains found in SITRAK C7H, HOWO T7H, and HOWO A7 heavy-duty trucks.

How does the aluminum alloy construction compare to cast iron alternatives?

Aluminum alloy offers a 40–50% weight reduction versus cast iron while providing superior thermal conductivity, which helps dissipate localized heat around the oil pump. The T6 temper delivers tensile strength above 290 MPa — more than adequate for the mechanical loads this cover experiences in service.

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

Absolutely. METTLEAD supports flexible MOQs specifically so procurement managers can validate fit, finish, and performance in the field before scaling up orders. Trial quantities typically ship within 3–7 working days from confirmed payment.

What quality inspections does each oil pump cover undergo?

Every unit passes through a three-stage QC gate: raw casting X-ray porosity check, CNC-machined dimension verification on a coordinate measuring machine, and a final visual and surface roughness inspection. Batch-level pressure-decay testing confirms sealing integrity before packaging.

Does prolonged storage affect the oil pump cover’s sealing surface?

Each cover ships with a protective anti-corrosion oil film and VCI (Volatile Corrosion Inhibitor) wrapping. Stored in a dry, indoor environment, the sealing surface maintains its specified flatness and finish for 24+ months without degradation.
