740.50-1307010 water pump for truck(Насос водяной КАМАЗ ЕВРО-2): Working Requirements and Integration Fit

Why the Right Part Number Is the Starting Point for KAMAZ Euro-2 Cooling System Procurement

Engine cooling is a non-negotiable system on heavy commercial trucks. A mismatched water pump — even one that physically fits — can deliver incorrect flow characteristics and cause premature engine wear or overheating. For KAMAZ Euro-2 engines, the 740.50-1307010 water pump for truck(Насос водяной КАМАЗ ЕВРО-2) is the OEM-designated replacement identified by part number 740.50-1307010. Verifying this number against the vehicle's existing pump or official service manual is the single most reliable first step before sourcing.

HEBEI LONGSHENGTENGYU PUMP INDUSTRY CO., LTD manufactures and supplies this pump alongside a broader range of engine cooling water pumps, gear pumps, hydraulic valves, and related driveline components.

Key Selection Criteria

1. OEM Part Number Verification

The pump is catalogued under OEM number 740.50-1307010 and is designated specifically for the KAMAZ Euro-2 (ЕВРО-2) engine family. This number must match the part number on the outgoing pump or the vehicle's spare parts catalogue. Cross-referencing with the engine serial number and model code is recommended before purchase.

For reference, the Euro-3 variant carries OEM No. 740.63-1307010 and a marginally different weight (5.78 kg vs. 5.72 kg for the Euro-2 unit). These two pumps are not interchangeable. Buyers maintaining Euro-3 platforms such as the KAMAZ-5460, -6520, -65201, -65225, -6560, -6460, -5297, -53605, -65111, -65115, -65116, and -6540 must specify OEM No. 740.63-1307010 instead.

2. Material and Physical Specification

The 740.50-1307010 unit is constructed from cast iron and has a confirmed weight of 5.72 kg. Cast-iron construction provides durability under the thermal cycling and vibration loads typical of heavy truck engines. Buyers should confirm that the replacement weight and mounting dimensions align with the existing installation before ordering.

3. Application Scope and Platform Fit

This pump is specified for the KAMAZ Euro-2 engine platform and is also listed for BELARUS application types, indicating relevance across former Soviet-market commercial vehicle platforms that share compatible engine families. Buyers operating mixed fleets should verify each truck's emission standard generation (Euro-2 vs. Euro-3) before specifying a pump variant.

For fleets running ZIL or BELARUS trucks that require a pulley-equipped pump with a different geometry, a separate unit — the 130-1307010 water pump (with pulley), OEM No. 130-1307009-B3, weight 17.2 kg — is available and serves that platform. This is a distinct, heavier assembly and is not a substitute for the 740.50-1307010.

4. Minimum Order Quantity and Packaging

The published MOQ for the 740.50-1307010 is 100 PCS under standard terms, though the supplier also accepts small orders from as few as 2 pieces. Packaging options include neutral packaging and customized packaging to meet export, resale, or OEM labelling requirements.

5. Quality Assurance and Warranty Coverage

HEBEI LONGSHENGTENGYU PUMP INDUSTRY CO., LTD applies a 100% factory test before shipment, with additional high-frequency sampling by quality inspectors in line with international standards. A 1-year warranty is offered on the water pump; documented quality problems within the warranty period are resolved at no charge, with ongoing technical support provided across the production life of the unit. Third-party inspection is accepted.

6. Payment and Delivery Terms

Accepted payment methods include T/T (30% deposit, 70% balance before shipment) and Western Union. Available delivery terms are FOB, EXW, CFR, CIF, FCA, and DAP. Indicative lead times are 3–4 days for in-stock items and 20–40 days for non-stock production runs. Buyers should confirm current availability directly with the supplier before relying on these figures for project scheduling. Sample orders are available for evaluation and testing prior to bulk purchase.

Euro-2 vs. Euro-3 KAMAZ Water Pumps: Side-by-Side Comparison

The Euro-3 variant is 0.06 kg heavier and carries a lower published standard MOQ of 50 PCS. Both share cast-iron construction, flexible packaging options, the same quality assurance process, and equal warranty coverage. Neither unit should be substituted for the other; correct selection depends solely on the engine generation of the truck being serviced.

When the 740.50-1307010 Water Pump for Truck Does Not Apply

• KAMAZ Euro-3 trucks: Specify OEM No. 740.63-1307010.
• ZIL or BELARUS trucks needing a pulley-equipped pump: Specify OEM No. 130-1307009-B3 (130-1307010 assembly, 17.2 kg).
• Applications where the OEM number cannot be confirmed: Do not select by weight or visual appearance alone. Confirm the part number against the vehicle's official spare parts manual before ordering.
