Fan Hydraulic Pump
Excavator Fan Pump
If your Komatsu D275A-5 is overheating on site, the fan hydraulic pump is one of the first parts to check. This small but critical pump drives the cooling fan, pulling air through the radiator to keep engine temperatures steady. When it fails, the machine quickly hits high heat limits, forcing you to shut down mid-job.
We carry the 708-1T-00420 708-1T-00421 pump for these Komatsu models. It's built to match the original specs exactly - same mounting pattern, same pressure rating, same flow. That means it lines up without modification, and works just like the factory part once installed.


We have the excavator fan pump for volvo EC950, komatsu D155AX-6, WA380-5M, D65EX-17, WA430, WA470-6, caterpillar 330C, 320C, 330D, 336D, 826H, Hyundai R385-9, R485, Doosan DX520, DL507, DX500, DX380
We keep this pump in our warehouse along with other common replacement parts. It's packed in a sturdy box sized to fit its 300 × 300 × 400 mm, 26 kg dimensions, so it arrives ready to install.
We've been working with these pumps long enough to know which ones fail most often and which ones are worth keeping in stock. If you have the part number or machine model, we can help you confirm the right fan hydraulic pump for your equipment.
