What Arrives Before the Machine Can Move Again

The pump is in stock, but the delivery timeline depends on how quickly we confirm the right variant for your exact engine build.

When a Kubota D722 or D902 overheats on a jobsite during peak mowing season, the crew is already losing money by the hour. The problem is rarely sourcing the part itself — it is confirming whether the worn nameplate still shows the correct number, or whether the machine serial falls within a range that uses this specific pump housing. [NEED_CITE: equipment identification challenges when nameplates are damaged or illegible in field conditions]

I have watched a repair stall for days because a blurry phone photo made it impossible to distinguish between two visually similar pump variants. That is why every inquiry here starts with rapid identification: send the part number, the machine model, or a clear photograph of the old unit, and the compatibility check comes back within hours, not days.

Fast Identification When the Nameplate Is Gone

Finding the right Water Pump 1E051-73036 in stock fast shipping replacement starts with confirming what is actually on the machine. Many BX1880 tractors and RTV-X900 utility vehicles have been in service long enough that paint, rust, or debris obscure the original identification plate. Our Guangzhou warehouse team handles these situations daily — a photograph of the old pump, the engine block casting number, or even the machine serial plate is usually enough to lock in the correct unit.

Stock Depth and Single-Piece Orders

This water pump is stocked as individual units because emergency field repairs rarely need more than one at a time. The one-piece minimum order quantity exists precisely for the landscaper whose ZD1021 mower went down Tuesday morning and cannot wait for a batch order. Whether you are a repair shop pulling a single unit for a customer machine or a fleet supervisor grabbing a spare for the shelf, the dispatch process is identical: confirm fitment, pack, and hand to the courier.

How Delivery Timelines Actually Break Down

Once fitment is confirmed, the clock starts on physical logistics. Express courier services such as DHL or FedEx typically move a package from Guangzhou to most international destinations within a defined window, while air freight suits heavier consolidated shipments. [NEED_CITE: international express courier transit time variables for automotive parts shipments] The quote you receive upfront includes the estimated arrival window — not a vague promise, but a date range based on current carrier schedules. Packaging is designed for courier handling: sealed box with anti-rust coating and protective foam, so the pump arrives in the same condition it left the shelf.

Reading the Specifications That Matter in the Field

The double-lip NBR bearing seals rated to 110°C are the component most directly tied to pump lifespan. Coolant in a small diesel engine can approach these temperatures under sustained heavy load, and single-lip seals tend to harden and leak well before that threshold. The MLS gasket with nitrile rubber coating provides a reliable block-to-pump seal without requiring sealant application during installation — a detail that matters when a mechanic is working in a dusty field environment rather than a clean bench. The ±0.05 mm housing machining tolerance ensures the impeller clearance stays within design limits, which directly affects coolant flow rate at idle where overheating problems usually surface first.

The Cost of Ordering the Wrong Pump in a Hurry

Rushing an order without confirming fitment is the most common reason a machine stays down longer than necessary. A pump that physically bolts on but has the wrong port orientation or impeller diameter will either leak immediately or fail to circulate enough coolant — and the failure may not show up until the engine is back under load. [NEED_CITE: consequences of incorrect coolant pump fitment on small diesel engine overheating] That second round of teardown, return shipping, and re-ordering turns a same-week repair into a multi-week ordeal, which is exactly what the identification process here is designed to prevent.

Why Source This Pump Through This Channel

The Guangzhou warehouse holds stock of common Kubota cooling system SKUs specifically because these engines fail in the field without warning. Part identification works from a part number, a machine model, a photograph, or a nameplate image — whichever is available on the shop floor. Cross-reference verification covers the superseded number 16871-73430 (reference only) to catch machines that were built with the earlier part number. The six-month warranty covers manufacturing defects with replacement on photographic evidence, so there is no need to ship a defective unit back before receiving support. Technical confirmation of engine variant compatibility is available before the order is placed, not after the part arrives and does not fit.

Documentation & Verification

• Commercial invoice listing part number 1E051-73036 and engine compatibility
• Cross-reference sheet noting 16871-73430 as interchange reference only
• Dimensional inspection record covering housing tolerance and port alignment
• Six-month warranty terms with photo-evidence replacement process
• Packing photographs showing anti-rust coating and foam protection before crate closure
• HS code and customs documentation support for international clearance

Stock, Shipping & Arrival

• Current shelf stock confirmed at quote stage with dispatch window

Send What You Have and We Will Confirm the Rest

Provide the part number if it is legible, the machine model and serial if the nameplate is intact, or a clear photograph of the old pump and the engine data plate if neither option works. The compatibility confirmation comes back quickly so the order decision can be made the same day.

Frequently Asked Questions

Q: Is water pump 1E051-73036 currently in stock and when can it ship? A: Yes, this pump is stocked in our Guangzhou warehouse. Once fitment is confirmed — typically within hours of receiving your machine model or photograph — the unit is packed and handed to the carrier. Exact dispatch timing is quoted at the inquiry stage based on current stock position and your time zone.

Q: Can I order just one piece for an emergency repair? A: The minimum order is one piece, with no batch requirement. This is designed for field breakdowns where a single Kubota D722 or D902 engine needs immediate attention. The pricing and shipping process for a single unit is the same as for larger quantities.

Q: My nameplate is worn or painted over — how do I confirm fitment? A: Send a photograph of the old pump, the engine block casting, or any readable identification marking. Our technical team cross-checks against machine serial ranges and known variant differences to confirm whether this pump matches your specific engine build before you commit to the order.

Q: How fast can express courier deliver this pump internationally? A: Transit time depends on destination and current carrier schedules. DHL and FedEx typically deliver within a defined window from Guangzhou to most international addresses. The estimated arrival range is provided at the quote stage so you can plan the repair schedule around the delivery date.

Q: What happens if the pump arrives and does not fit my machine? A: Contact us immediately with photographs showing the fitment issue. If the incompatibility resulted from our identification error, a replacement is dispatched with expedited shipping. The six-month warranty covers manufacturing defects separately from fitment confirmation.
