Original buyer tool
Water pump interface comparison
JIA CHENG prepared the comparison table as a blank RFQ tool for recording housing, drive, coolant-port and impeller evidence.
This is an original JIA CHENG procurement worksheet supplied as a blank decision aid. It does not represent a customer case, test report or completed inspection record.
Key takeaways
- Engine model and serial provide the primary application path for an engine water pump.
- Housing, ports, hub, pulley and impeller details distinguish closely related pump variants.
- Quotation scope should list gaskets, seals, pulley, hub and housing separately.
- Cooling-system diagnosis should address leaks, drive condition, coolant flow and overheating evidence.
Establish truck and engine application
Engine cooling parts need both truck and engine identification because a forklift family can use different engine or cooling configurations. Record the truck model and serial, engine model and serial, fuel type and installed water-pump reference before dismantling. [1] [2]
- Photograph the truck plate, engine plate and water pump in its installed position.
- Copy casting, stamped and labelled references with their exact locations.
- Record fan, belt, pulley and hose arrangement around the pump.
Compare housing, drive and coolant interfaces
JIA CHENG procurement practice: Use the removed part and current service information to compare the complete pump. Photograph the gasket face, impeller, ports, hub or pulley and mounting holes. Include measurements with units and identify whether the fan or pulley transfers from the old assembly.
| Interface | Evidence | Quotation question |
|---|---|---|
| Housing | Bolt pattern and gasket outline | Complete housing or pump insert? |
| Drive | Pulley grooves, hub diameter and offset | Pulley or hub included? |
| Coolant ports | Count, diameter and direction | Hose layout matches? |
| Impeller | Diameter, depth and blade form | Engine application confirmed? |
Record diagnosis and installation scope
OSHA maintenance requirements place industrial-truck repair with authorized personnel. A water-pump request should record the confirmed leak, bearing, drive or circulation finding and any overheating event. Installation should follow the approved coolant, belt, torque, bleeding and functional-check procedure. [3]
- Check adjacent belt, fan, radiator, hoses, thermostat and drive components through qualified diagnosis.
- Ask the supplier to list every included gasket, seal, hub and fastener.
- Retain post-repair temperature and leak-check results with the maintenance record.
Frequently asked questions
Can an engine model confirm a forklift water pump?
The engine model narrows the catalogue. Engine serial, truck serial range, housing, pulley, ports, impeller and installed reference complete the verification.
Does a forklift water pump include the gasket and pulley?
Supply scope differs by reference. Require the quote to state whether the gasket, seal, hub, pulley, housing and installation hardware are included.
What failure evidence should be sent with a water pump RFQ?
Send the qualified diagnosis, leak location, shaft or bearing finding, drive condition and any overheating history, plus clear component and plate photographs.
