708-7S-00550 Hydraulic Cooling Fan Motor Assembly for Komatsu WA380 / WA430 / WA470 / WA480-6

This 708-7S-00550 fan motor is a new aftermarket hydraulic cooling fan motor assembly for Komatsu WA380-6, WA430-6, WA470-6 and WA480-6 wheel loaders. It drives the engine cooling fan through the hydraulic circuit, holding stable fan speed so the radiator keeps coolant temperature under control during loading, hauling and continuous duty cycles.

Key Features

• Direct fit replacement — mounting flange, shaft spline and port positions matched to the original 708-7S-00550 motor, so it bolts on without modification.
• Bench tested before shipment — every motor is run on the test bench and checked for output speed, torque and internal leakage.
• Precision machined rotor group — lapped mating surfaces and hardened components reduce internal wear in high-hour cooling circuits.
• Heat-resistant sealing — shaft seal and O-rings selected for continuous operation in hot engine compartments and dusty job sites.
• Export packing — each motor is foam wrapped and packed in a carton or wooden case for long-distance shipping.

Typical Symptoms of a Failed Fan Motor

• Engine coolant temperature climbing under load or in hot weather
• Fan turning slowly or not responding to temperature demand
• Whining, knocking or grinding noise from the fan drive area
• Oil leakage around the motor housing or shaft seal
• Hydraulic oil overheating and loss of fan speed control

Frequently Asked Questions

Q1: How do I confirm this fan motor fits my machine?
A: Send us your machine model, serial number and a photo of the original motor nameplate. We verify compatibility and reply within 24 hours — this avoids costly wrong orders for dealers ordering on behalf of end users.

Q2: What is the MOQ, and how is the price set?
A: Minimum order quantity is 1 unit. Price is negotiable and quoted against your order quantity, destination port and packing requirement. Please contact us with your target quantity for an exact price.

Q3: What are the warranty terms?
A: Warranty terms are negotiable and confirmed per order, based on quantity and application. We can agree on the inspection standard and claim procedure in the contract before shipment.

Q4: Can you supply HS code, invoice and packing list for customs clearance?
A: Yes. We provide commercial invoice, packing list, HS code and origin documents for every shipment, and can work with your forwarder or broker in the destination country.

Q5: Do you have CE or other test documents for European buyers?
A: We can supply material and test reports and discuss the documentation package your market requires. Please tell us the destination country at inquiry stage so the paperwork is prepared before shipping.

Q6: Is this fan motor reliable in high ambient temperature, dust and sand?
A: The motor uses hardened internals and heat-resistant seals for continuous duty. For Middle East, Africa and Southeast Asia job sites we recommend keeping hydraulic oil clean and the fan circuit filter serviced; we can advise on the correct oil grade for your climate.

Q7: How does it perform in cold climate and winter start-up?
A: For Russia, CIS and North America winter operation the motor works with the oil grade specified by the machine manufacturer. We can recommend a viscosity grade suitable for low temperature start-up to protect the motor during warm-up.

Q8: Which shipping terms and ports do you support?
A: FOB, CIF and door-to-door options are available. We ship from South China ports and can arrange air freight for urgent breakdown cases. Tell us your nearest port and we will quote the freight option that suits your volume.
