What Arrives Before the Machine Can Move Again

The Water Pump 1E051-73036 in stock fast shipping from our Guangzhou warehouse reaches most Asia-Pacific buyers within days, not weeks.

When a Kubota D722 or D902 engine is already sitting hot on a bench, every hour spent confirming part numbers is an hour the machine stays down. I have watched a Kubota D722 sit idle in a vineyard for days because a supplier sent a pump without the mating gasket, forcing a second order cycle.

That delay is what this stocking approach eliminates.

Dispatch Windows That Match Your Repair Timeline

The Water Pump 1E051-73036 in stock fast shipping is confirmed before you commit to payment. Guangzhou warehouse inventory on this pump and its companion gasket 16871-73430 (cross-reference only) moves same-day when the order lands before the courier cutoff. Express carriers cover regional destinations within a typical window, and we quote arrival timing at the point of inquiry rather than leaving it to guesswork after checkout.

How the Right Pump Gets Identified from a Faded Nameplate

Field conditions rarely give you a clean part number. Paint overspray, corrosion, and years of heat cycling turn a legible plate into a smudge. Send a photograph of the nameplate or simply the machine model — BX1880, RTV-X900G, ZD1021 — and the correct pump variant is confirmed within hours. [NEED_CITE: equipment identification challenges in aftermarket parts distribution] This pump fits Kubota D722 and D902 engine families across multiple machine platforms, so model-level verification is often enough when the stamped number is unreadable.

Inside the Flow Path and Mounting Interface

This aftermarket water pump circulates coolant through the D722 and D902 block at rates matched to the factory thermostat and radiator capacity. The impeller geometry and volute casting are dimensioned for the original belt-drive speed, maintaining correct flow without cavitation at operating RPM. The included gasket 16871-73430 (cross-reference only) seals the pump-to-block mating surface, eliminating the separate sourcing step that commonly delays field repairs. Mounting bolt pattern and pulley alignment match the OEM reference 1E051-73036 (for identification purposes) envelope so the existing belt and bracket transfer directly.

The Real Cost of Getting the Wrong Pump Shipped

A pump that physically bolts on but has the wrong impeller diameter or port orientation creates a subtler problem than one that simply does not fit. Coolant flow falls short under sustained load, the thermostat cycles wide open, and the operator assumes a deeper engine fault. By the time the misdiagnosis is caught, the head gasket has absorbed thermal stress it was not designed for. [NEED_CITE: thermal cycling damage to cylinder head gaskets in compact diesel engines] One wrong shipment means a second round of downtime, a second freight charge, and a repair window that stretches into the next workweek.

Why This Pump Ships from Here

Guangzhou warehouse stock on this water pump and gasket set means emergency orders do not wait for production runs. One-piece minimum order keeps a single repair moving without forcing bulk purchases on a contractor who needs one pump today. Part identification from a photograph or machine model cuts the back-and-forth that delays urgent orders. Express, air, and sea freight options are quoted with arrival timing upfront so the buyer knows when the machine runs again. Technical verification on engine serial variants and superseded numbers happens before dispatch, not after the box arrives on site.

Confirming the Fit Before You Install

When this pump arrives, place the included gasket against the block mating surface to verify port alignment before applying sealant. Check that the pulley bore and keyway match the removed pump. Spin the impeller by hand to confirm free rotation with no bearing roughness. If any dimension does not match, stop installation and send a photograph for immediate resolution.

Getting the Right Part Identified Fast

Provide the machine model stamped on your Kubota frame plate, or send a clear photograph of the existing pump and nameplate. Include any visible casting numbers on the old pump body. With that information, stock status and arrival timing for the Water Pump 1E051-73036 in stock fast shipping are confirmed the same day.

Frequently Asked Questions

Q: Is this water pump currently in stock and how fast can it ship? A: Yes, this pump with the companion gasket is held in Guangzhou warehouse inventory. Orders placed before the daily courier cutoff dispatch the same business day. Express delivery timing to your specific region is quoted at the point of inquiry so you know the arrival date before committing.

Q: Can I order just one piece for an emergency repair? A: Absolutely. The minimum order is one pump with one gasket. There is no bulk threshold to clear before an emergency single-piece order ships. This keeps small contractors and independent workshops from waiting on minimums when a machine is already down.

Q: My nameplate is faded — can you identify the right pump from a photo? A: Yes. Send a photograph of whatever remains readable on the nameplate, or simply the machine model such as RTV-X900G or ZD1021. The correct pump variant for Kubota D722 and D902 engines is typically confirmed within hours, even when stamped numbers are partially illegible.

Q: What happens if the pump arrives and does not fit? A: Notify us immediately with a photograph of the mating surface and bolt pattern. A replacement or correct variant is arranged under the six-month warranty. Pre-shipment verification from machine model or serial number is designed to prevent this, but resolution is fast if a mismatch occurs.

Q: What are the express delivery timeframes to my region? A: Express carrier transit windows depend on destination and are quoted individually at inquiry. The Water Pump 1E051-73036 in stock fast shipping departs Guangzhou within one business day, and the quoted arrival estimate accounts for customs clearance variables where applicable.
