Sending a clear image of your existing pump or engine data plate eliminates guesswork and prevents a second round of downtime.
I have handled too many urgent requests where a buyer in a remote mining region reported a machine down and provided only the engine family — D722 or WG972 — assuming that was enough to ship the correct unit. Kubota engine families span dozens of build variants, and the oil pump interface can differ between production runs. One misidentified pump means the machine sits dead for another week while the return and replacement cycle plays out. When the nameplate is painted over or corroded, a clear photograph of the old pump body, mounting face, and port positions lets our technical team cross-verify against known variant builds before anything leaves the warehouse.

This Oil Pump 16851-35012 replacement sits in our fast-moving stock category because lubrication failures do not wait for planned maintenance windows. Guangzhou warehouse inventory is monitored daily, and when you need one unit for a machine that is already on the bench, there is no minimum order threshold to clear. You order one, it ships as one. The entire confirmation flow — stock check, fitment verification, freight quote with estimated arrival — runs within a single exchange so the part is moving before the end of your working day.
Arrival time depends on the shipping method selected at quote stage, not on warehouse processing delays. Express air dispatch from Guangzhou reaches most international hubs within a defined window, and the tracking reference is shared the moment the courier collects the parcel. For a contractor with an excavator down on a jobsite or a repair shop working against a customer deadline, knowing the realistic arrival window before committing to the order changes the repair plan from uncertain to scheduled. We quote the freight options and their delivery estimates alongside the part confirmation so there are no surprises after payment.

The pump must maintain adequate oil volume across the full RPM range of engines like the D722 and D902, which operate under varying thermal loads depending on application. In excavator installations, sustained high-RPM digging cycles generate more heat in the lubrication circuit than intermittent tractor use, so the pump's internal clearances must stay within tolerance to avoid pressure bleed-off when the oil thins at operating temperature. The cross-reference numbers listed above — such as 15841-35010 and 16851-35014 — reflect superseded and alternate production versions that share the same mounting pattern and drive interface. Confirming which version your engine carries prevents receiving a pump that physically bolts on but delivers incorrect volume at the galleries.
Ordering an oil pump based on engine family alone and finding it does not match upon arrival means the machine stays down through an entire return-and-reship cycle. In a mining or construction context, that extended downtime compounds into lost production shifts, idle operator costs, and schedule pressure on dependent tasks. Even when the pump physically mounts but the internal rotor profile or drive tang width differs from the original, the result is low pressure that damages bearings before the fault is diagnosed. Verification before dispatch — using a photo, the old part number, or the machine serial — removes this entire failure chain.

Stock depth on this oil pump means your urgent order does not sit in a production queue. Our Guangzhou warehouse holds fast-failure lubrication components ready for immediate picking, so the dispatch timeline depends on courier schedules, not manufacturing lead times. Part identification works from whichever reference you have available — a readable part number, a machine model, a photograph of the old unit, or a shot of the engine data plate — and our team cross-checks against superseded numbers like 16851-35010 and 15841-35010 before confirming. Single-piece orders ship without MOQ friction, and the same three-month warranty covers every unit whether you order one or fifty. Technical confirmation on variant fitment is part of the pre-dispatch process, not an afterthought.
Send us the part number from your old pump, a clear photograph of the unit or engine nameplate, or the machine model and serial number. We will confirm whether this Oil Pump 16851-35012 replacement matches your specific engine build, quote the freight options with estimated arrival times, and have the parcel ready for same-day dispatch from our Guangzhou warehouse once you approve.
Q: Is this oil pump currently in stock and when can it ship? A: This Oil Pump 16851-35012 replacement is stocked in our Guangzhou warehouse for fast dispatch. Once you confirm the fitment details and approve the freight quote, the parcel is handed to the courier the same day or the next business day. We provide the tracking reference immediately upon collection so you can monitor transit progress to your location.
Q: Can I order just one unit or is there a minimum quantity? A: There is no minimum order quantity on this part. A single oil pump ships on its own, which matters when a machine is already down and you need one replacement to close the job. You do not have to bundle other items or wait to accumulate a larger order before the warehouse releases your unit for dispatch.
Q: My nameplate is worn off — can I send a photo to confirm the part number? A: Yes. A clear photograph of the old pump body, the mounting face, and any visible casting marks allows our technical team to identify the correct variant. We cross-reference against superseded numbers and known engine build configurations to verify fitment before anything ships, reducing the risk of receiving a mismatched unit.
Q: How long will delivery take to my location? A: Transit time depends on your destination and the freight method chosen. We quote express air, standard air, and sea options with estimated arrival windows at the quote stage, so you know the realistic timeline before committing. Express air from Guangzhou reaches most international hubs within a short defined window for urgent jobsite needs.
Q: What happens if the part I receive does not fit my machine? A: If the part does not match the confirmed fitment specification we agreed upon before dispatch, our warranty process covers the resolution. This is why we verify using your machine serial, photo, or old part number before shipping — it prevents mismatch situations from arising in the first place and keeps your repair on schedule.
