Tired of Overheating Engines and Unexpected Downtime? Get the Right Kubota Water Pump 1E051-73036 for Your D722 and D902 Engines

Construction and agricultural equipment operators know: a failed water pump stops everything. One hour of downtime on a Kubota RTV-X900 or D722-powered tractor can cost hundreds in lost labor and missed deadlines. Counterfeit or low-grade replacements fail within weeks — often causing coolant leaks, bearing damage, or complete engine overheating. OEM parts take 3+ weeks to arrive and cost up to 45% more.

OEM-Equivalent Quality, Ready to Ship from Guangzhou Warehouse

This Kubota water pump 1E051-73036 is engineered to match original specifications — manufactured in ISO 9001-certified facilities, tested for flow rate, pressure stability, and seal integrity before shipment. With 10 years of global export experience and 10,000+ SKUs in stock, XUNPO delivers verified replacement parts for Kubota D722 and D902 engines used in utility vehicles, zero-turn mowers, and compact tractors — no waiting, no guesswork.

Where This Part Works

The Kubota D722 and D902 engines power machines operating in demanding environments: municipal grounds maintenance, vineyard terracing, port-side material handling, and small-scale demolition support. Under continuous load, these engines rely on consistent coolant circulation. A weak impeller or compromised gasket leads directly to thermal stress, cylinder head warping, and premature failure — especially in high-ambient-temperature regions like Southeast Asia or the Middle East.

Engineering Details That Matter

The pump housing is precision-cast aluminum alloy with T6 heat treatment for dimensional stability under thermal cycling. The impeller is balanced to ISO 1940 G6.3 standards to prevent vibration-induced bearing wear. Shaft seals use dual-lip NBR rubber rated for continuous operation at 120°C and compatibility with Kubota KUBOTA ULTRA COOLANT. The gasket (16871-73430) is multi-layer steel (MLS) with elastomeric coating — ensuring leak-free sealing across expansion differentials between cast iron block and aluminum housing. All critical dimensions are held to ±0.05 mm to guarantee drop-in fit without machining or shimming.

The Real Cost of Wrong Parts

A $25 counterfeit water pump may save upfront, but its soft aluminum housing deforms after 200 hours, causing misalignment and rapid bearing failure. Repairing that damage costs 5× more than the original part — plus 1–2 days of machine idleness. Industry data shows non-OEM-equivalent pumps reduce service life by 60% and increase coolant-related failures by 2.3×. Choosing this Kubota water pump 1E051-73036 means adherence to ISO 8502 surface cleanliness standards, OEM-specified torque values, and validated thermal expansion coefficients — delivering true total cost of ownership (TCO) control.
