Why the Same Part Number Ships in Multiple Variants Across D902 Generations

The number on your old starter may cross-reference to several builds, but only one variant fits your engine serial range.

A 12V Starter Motor for Kubota D902 Engine cross reference fitment inquiry arrives almost every week where the buyer holds a part number that technically matches multiple production runs. The D902 family has been in service across construction, agricultural and generator applications for many years, and Kubota revised the starter mounting geometry and terminal layout across those generations. A part number like 16824-63010 was superseded by 16824-63011, then 16824-63012, and eventually 16824-63013 — each carrying subtle differences in flange thickness, bolt hole spacing, or solenoid terminal orientation [NEED_CITE: Kubota D902 starter motor supersession history across engine serial ranges]. I once had a customer in Southeast Asia order based on a cross-reference table he found online. The number matched, but his D902-E2B build required a different mounting hole offset. The unit sat in his workshop for weeks while we sent a corrected replacement. That is why we now verify every 12V Starter Motor for Kubota D902 Engine cross reference fitment request against the actual engine serial, not just the base model designation.

Mapping Superseded Numbers to Your Specific D902 Build

The cross-reference chain from 16824-63010 through 16824-63014, along with alternate references like LRS04119 and the M000T8808x Mitsubishi series, can create confusion when sourcing a 12V Starter Motor for Kubota D902 Engine cross reference fitment replacement. Each superseded number was tied to a production period and specific engine serial range. Our technical team maps these numbers against your engine plate or serial stamp to determine which variant actually fits. When a buyer sends us only the old starter label and the label is faded or painted over, we cross-check the physical characteristics — flange profile, solenoid clocking position, terminal post layout — to narrow down the correct build.

Mounting Flange, Gear Mesh and Connector Verification

Before any unit leaves our Guangzhou facility, we check the dimensional details that determine whether this starter physically fits your engine block. The 8-tooth drive gear must engage the flywheel ring gear at the correct depth and backlash. The mounting flange bolt pattern is measured against the D902 variant specification — some builds use a two-bolt pattern with a specific angular offset that differs from the three-bolt arrangement on earlier runs [NEED_CITE: starter motor mounting flange standards for small diesel engines]. The 12V electrical connector type is verified against the harness plug on your machine. We have seen cases where the electrical terminals were rotated to a different clock position between superseded variants, making the wiring harness reach impossible without modification.

Electrical Ratings and Drive Gear Specification Breakdown

The 1.2KW output at 12V positions this starter for the cranking torque requirements of the D902 three-cylinder diesel. This power rating delivers sufficient cranking speed for cold starts in temperate climates while keeping current draw within the capacity of standard machine wiring harnesses and battery configurations. The 8-tooth drive gear is cut to mesh with the Kubota D902 flywheel ring gear tooth profile — a mismatch in tooth count or module would result in partial engagement, accelerated gear wear, or failure to crank [NEED_CITE: starter drive gear tooth module matching for diesel engine applications]. The 12V system voltage is standard across most D902 installations in excavators, compact loaders, and generator sets.

What Happens When the Wrong Variant Gets Installed

Shipping back a starter motor that does not fit costs far more than the freight charge. The machine sits idle while the return is processed and the correct unit is identified and dispatched. In worse scenarios, a variant that almost fits — where the bolt holes align but the drive gear sits at the wrong engagement depth — may crank the engine initially but cause ring gear damage over repeated starts [NEED_CITE: starter motor gear engagement depth and flywheel ring gear wear correlation]. We have received return requests where the buyer forced installation despite noticing the solenoid terminal was on the wrong side, leading to harness strain and eventual connector failure within days of use.

Why Buyers Source This Starter Through Our Desk

We produce selected part lines in our own facility and source the remainder from qualified ISO 9001-certified manufacturing partners, so every 16824-63013 unit carries the same warranty terms regardless of production origin. Our Guangzhou warehouse stocks common D902 starter variants for fast dispatch. We accept orders from a single piece — no minimum quantity blocks an emergency replacement. Our technical team confirms fitment from a part number, machine model, engine serial, or a photograph of the old unit and nameplate. Cross-reference verification covers the full supersession chain including discontinued numbers. We offer sample units so you can physically verify fitment before committing to a bulk order.

Documentation & Verification

• Commercial invoice and packing list with 16824-63013 and D902 variant details noted
• Part compatibility and cross-reference sheet mapping superseded numbers to your engine serial (reference only)
• Dimensional inspection record covering flange bolt pattern and 8-tooth gear profile before dispatch
• Warranty terms document specifying coverage period against manufacturing defects
• Packing photographs showing the unit secured and protected for transit
• HS code and customs classification support for international shipment clearance

Fitment Check Before Installation

• Compare the 8-tooth drive gear tooth profile against your old unit before mounting
• Verify the mounting flange bolt hole spacing matches the D902 block pattern
• Check solenoid terminal orientation aligns with your existing wiring harness reach
• Confirm the connector type matches the machine-side plug before final tightening
• Bench-test the starter with a 12V source to verify engagement before engine installation
• If any dimension differs from your old unit, contact us with photographs before proceeding

Send Us Your Engine Details for a Confirmed Fitment Match

To verify whether 16824-63013 is the correct starter for your machine, send us the Kubota engine model, serial number from the engine nameplate, or a clear photograph of your existing starter showing the mounting flange and label. If the nameplate is worn or painted over, a photo of the engine block casting number and the old starter's physical features is enough for our team to cross-reference the correct variant. We will respond with a confirmed fitment match or advise if a different build in the supersession chain applies to your serial range.

Frequently Asked Questions

Q: How do I confirm this starter fits my specific Kubota D902 variant? A: Send us your engine serial number from the nameplate or a photograph of the existing starter showing the mounting flange and solenoid position. We cross-check these details against our fitment database to confirm whether 16824-63013 matches your specific D902, D902E, or D902-E2B build, including bolt pattern and terminal orientation.

Q: My old starter has a different number — can I still use 16824-63013? A: The D902 starter line has multiple superseded numbers including 16824-63010 through 16824-63014 and several aftermarket cross-references. A different number on your old unit may still correspond to the same physical build. Send us the number and we will verify the cross-reference chain against your engine serial range.

Q: Why are there multiple part numbers for the same engine family? A: Kubota revised the starter mounting geometry, solenoid configuration, and terminal layout across different D902 production periods. Each part number in the supersession chain corresponds to a specific engine serial range and build variant. We map these differences to ensure you receive the variant that physically fits your engine.

Q: I only have the machine model, no readable part number — can you identify the right starter? A: Yes. Provide the machine model and, if possible, a photograph of the engine nameplate or the old starter from multiple angles. Our team uses the machine model and visual details like flange shape, bolt count, and connector type to narrow down the correct 12V starter variant for your application.

Q: Can I get a sample to test fitment before ordering in quantity? A: We supply single sample units specifically for physical fitment verification. Mount the sample on your D902 engine, confirm the bolt pattern, drive gear engagement, and terminal orientation match, then proceed with your bulk order once fitment is confirmed on site.
