About Hubei Huacumda Machinery Co., Ltd. - Engine Spare Parts Supplier in China

China‑based Hubei Huacumda Machinery Co., Ltd. lists 26 active products across several mechanical categories. The catalogue includes engine components such as crankshaft (HS 8483.40, forged steel/carbon steel alloy) and camshaft, automotive alternators identified under HS 8511.50 with copper windings and steel housings, as well as turbochargers like the Holset model classified under HS 8414.80. Additional items cover fuel and water pumps, cylinder liners, piston rings, and various fuel injectors for brands such as Cummins, Volvo and Caterpillar. Each entry specifies material composition where provided, reflecting typical alloy or cast‑iron constructions used in heavy‑duty equipment.

The product set spans engine spare parts, electric alternators, diesel generator accessories, industrial pumps and related components. Materials range from forged steel alloys for rotating shafts to cast‑iron housings for turbochargers and polymer‑based brush assemblies in alternators. HS code families referenced include 8483 (machine parts), 8511 (electric generators, alternators) and 8414 (air or gas compressors, turbochargers). The supplier’s listed items are primarily aftermarket replacements for construction, mining and agricultural machinery.

Product Range and Specialties of Hubei Huacumda Machinery Co., Ltd.

The catalogue features crankshafts, camshafts, oil pressure sensors, Volvo and other brand alternators, fuel and lube pumps, cylinder liners, piston rings and a variety of fuel injectors. In the automotive aftermarket, crankshafts are typically supplied in forged steel grades such as 42CrMo or 35CrMo, meeting hardness values of 45‑55 HRC. Alternators for heavy trucks usually conform to IEC 60034‑1 standards, with copper windings of class 5 and aluminum or steel housings designed for 400‑600 V DC output. Turbochargers like the Holset model are cast from high‑temperature alloy iron and often meet ISO 9001 quality management requirements for dimensional tolerance (±0.05 mm on rotor clearance). Pumps for diesel engines are commonly machined from cast iron or bronze and tested for flow rates between 30‑120 L/min at 150 psi. Piston rings are supplied in carbon‑steel or cast‑iron grades with tensile strength above 800 MPa, and injectors are calibrated to deliver fuel within ±2 % of the nominal flow rate at pressures up to 2500 bar.

Trade and Export Information - Hubei Huacumda Machinery Co., Ltd.

China is a global exporter of engine aftermarket parts, alternators and turbochargers, supplying markets in Southeast Asia, the Middle East, Africa and Europe. HS 8483.40 items such as crankshafts are typically shipped in 20‑ft or 40‑ft containers with wooden crates, while HS 8511.50 alternators are packed in moisture‑proof cartons and may be subject to CE marking or IEC certification for electrical safety. Turbochargers under HS 8414.80 often require compliance with ISO 9001 and may be inspected under the Chinese export inspection system (CIQ) before release. Common Incoterms for Chinese machinery exporters are FOB Shanghai or Ningbo and CIF to destination ports, with freight rates calculated per container load. Buyers frequently request test reports covering material composition, hardness, dimensional tolerance and electrical performance for alternators, as these documents are standard for automotive OEM and aftermarket sourcing.

Sourcing from Hubei Huacumda Machinery Co., Ltd. - Buyer Guidance

When sourcing from Hubei Huacumda, buyers should request material test certificates that confirm steel grade, carbon content and hardness for crankshafts and camshafts. For alternators, ask for IEC 60034 compliance reports, winding resistance measurements and insulation resistance values. Turbochargers and pumps should be accompanied by flow‑rate test data and pressure‑surge test results. Verify that the supplier can provide ISO 9001 or automotive‑specific ISO/TS 16949 quality certificates, or obtain third‑party inspection reports before confirming an order. Typical minimum order quantities for forged components range from 100 to 500 units, with lead times of 30‑45 days after receipt of a confirmed purchase order. Packaging is usually in wooden crates with internal bracing; confirm crate dimensions to ensure container fit.

What product categories does Hubei Huacumda list in its catalogue?

The supplier lists engine spare parts (crankshaft, camshaft, piston rings), electric alternators, diesel generator components, industrial pumps, cylinder liners, turbochargers and fuel injectors.

Which HS codes are associated with the listed products?

Crankshaft uses HS 8483.40, the alternators are under HS 8511.50, and the Holset turbocharger falls under HS 8414.80. Other items share the same HS families based on their function.

What material specifications should a buyer verify for the crankshaft?

Buyers should verify that the crankshaft is forged steel or carbon‑steel alloy, typically grade 42CrMo or equivalent, with a hardness of 45‑55 HRC and compliance with ISO 9001 dimensional tolerances.

How are the alternators typically constructed and tested?

Alternators are built with copper windings, steel or aluminum housings and polymer brushes. They are tested for voltage output (400‑600 V DC), winding resistance, insulation resistance and IEC 60034‑1 compliance.

What certifications are commonly required for these automotive components?

Buyers usually request ISO 9001 quality management certification, ISO/TS 16949 for automotive parts, and CE or IEC safety approvals for electrical products such as alternators.

What are typical packaging and shipping methods for these items?

Heavy components like crankshafts and turbochargers are packed in wooden crates with internal bracing, while alternators are placed in moisture‑proof cartons. Shipments are normally sent in 20‑ft or 40‑ft containers under FOB Shanghai or CIF to the destination port.

What documentation should a buyer ask for before placing an order?

Request material test reports, hardness certificates, dimensional inspection reports, electrical performance test sheets for alternators and flow‑rate test data for pumps. Also ask for any available quality system certificates.

What are typical lead times and minimum order quantities for these products?

Lead times are generally 30‑45 days after order confirmation. Minimum order quantities range from 100 units for smaller parts like piston rings to 500 units for larger forged components such as crankshafts.
