UD16994S Denso Starter Motor 12V 1.2kW 9T

UD16994S Denso Starter Motor B2B Supply for Aftermarket Buyers

UD16994S gives aftermarket buyers a defined 12V, 1.2kW, 9-tooth clockwise configuration for Denso vehicles and equipment cross-referenced to UD16994S. Link the complete reference group to the buyer's machine or engine record, then approve the mounting geometry, pinion position and terminal layout before releasing distributor stock.

The distributor record for UD16994S should connect the reference group UD16994S / 91-29-5410 / 128000-8450 / 31391-91A / 256083 / 0280007300 / 18477N、17632R with Denso vehicles and equipment cross-referenced to UD16994S. Add the old-unit label, mounting-face image, terminal view and receiving result to that record. Reuse it for repeat quotations, but create a new revision whenever the supplier changes the suffix, housing, pinion or electrical rating. A disciplined record reduces avoidable substitutions during urgent replenishment.

UD16994S Starter Motor OE Cross-Reference Review for Bulk Procurement

Use UD16994S as the primary purchasing reference and cross-check 91-29-5410, 128000-8450, 31391-91A, 256083, 0280007300, 18477N、17632R. These numbers identify the candidate starter family, but approval still requires the exact suffix, electrical rating, drive end, mounting geometry, pinion and terminal layout to match the removed unit or signed sample.

UD16994S Starter Motor Bulk Fitment Approval for B2B Supply

Confirm the complete UD16994S / 91-29-5410 / 128000-8450 / 31391-91A / 256083 / 0280007300 / 18477N、17632R group together with the 12V, 1.2kW, 9-tooth clockwise configuration. Similar appearance or a shared partial number is not enough; compare equipment and engine record, complete OE, mounting face, pinion position and terminal arrangement against the removed unit or approved sample and keep the signed sample with the purchase record.

UD16994S Starter Motor Wholesale Receiving Inspection for Aftermarket Buyers

For a wholesale shipment, sample units across the UD16994S lot rather than inspecting only the top carton. Compare reference label, electrical rating, drive end, mounting geometry, terminals, packing and lot traceability with the approval record and document pass, fail and hold quantities. Do not mix a disputed suffix or drive-end version with cleared stock, even when the outer housing looks alike.

UD16994S Starter Motor Distributor FAQ for Wholesale Supply

Where is UD16994S commonly used, and what still needs confirmation?

Confirm the complete UD16994S / 91-29-5410 / 128000-8450 / 31391-91A / 256083 / 0280007300 / 18477N、17632R group together with the 12V, 1.2kW, 9-tooth clockwise configuration. Similar appearance or a shared partial number is not enough; compare equipment and engine record, complete OE, mounting face, pinion position and terminal arrangement against the removed unit or approved sample and keep the signed sample with the purchase record.

What specification mismatch creates the greatest risk on UD16994S?

Confirm the complete UD16994S / 91-29-5410 / 128000-8450 / 31391-91A / 256083 / 0280007300 / 18477N、17632R group together with the 12V, 1.2kW, 9-tooth clockwise configuration. Similar appearance or a shared partial number is not enough; compare equipment and engine record, complete OE, mounting face, pinion position and terminal arrangement against the removed unit or approved sample and keep the signed sample with the purchase record.

Which configuration checks prevent a mismatched UD16994S order?

Confirm the complete UD16994S / 91-29-5410 / 128000-8450 / 31391-91A / 256083 / 0280007300 / 18477N、17632R group together with the 12V, 1.2kW, 9-tooth clockwise configuration. Similar appearance or a shared partial number is not enough; compare equipment and engine record, complete OE, mounting face, pinion position and terminal arrangement against the removed unit or approved sample and keep the signed sample with the purchase record.

Which mounting details should be compared before ordering UD16994S?

Measure and compare the equipment and engine record, complete OE, mounting face, pinion position and terminal arrangement with the removed starter. Check bolt-hole spacing, locating diameter, starter clocking, pinion rest position and rear-terminal clearance instead of judging from the outer housing alone. Never pull a misaligned unit into place with mounting bolts. A measured or photographed fitment record is especially valuable when nearby references share the same voltage and tooth count but use another drive-end or solenoid orientation.

Which incoming-inspection points matter for UD16994S?

Tie every carton and sampled unit to UD16994S, the approved cross-reference set and the supplier lot. Inspect reference label, electrical rating, drive end, mounting geometry, terminals, packing and lot traceability, then compare the sampled unit with the signed photos or dimensional document. Record pass and fail quantities before the stock is mixed. Quarantine any different rating, pinion, mounting face or terminal layout, because an unverified substitute can stop equipment, generate a claim and turn a low unit price into a costly order. This receiving discipline is cheaper than sorting returns after distribution.

Can a similar 12V starter replace UD16994S?

A substitute is acceptable only when its complete OE relationship, 12V system, 1.2kW rating, 9T, rotation and mounting geometry agree with the approved unit. Similar appearance or a shared partial number is not enough. Ask for application and old-unit evidence, then test or approve a sample before changing the order line. Keep materially different versions separate in inventory so warehouse staff cannot fulfil one inquiry with the wrong variant.

How can buyers separate a UD16994S fault from an equipment fault?

Check battery capacity, voltage drop, start signal, grounds, ring gear and mechanical engine load before condemning the starter. Record battery voltage at rest and during the start command, then measure voltage drop under load; a weak supply or poor ground can imitate starter failure. Inspect the mounting surface and gear engagement as well. Attach these results, the old-unit label and failure symptoms to the claim so the supplier can distinguish a product defect from an upstream electrical or mechanical problem.

What makes a UD16994S RFQ technically complete?

Send UD16994S and all visible OE numbers, the full application or engine record, required quantity, destination and target delivery date. Add clear photos of the label, drive end, mounting face and terminals, plus any dimensional drawing available. State packaging, private-label, sample and inspection requirements at the start. A technically complete RFQ lets the supplier quote one verified configuration and reduces clarification delays after price approval.

How are MOQ, samples and repeat orders managed for UD16994S?

The standard MOQ is 20 pieces, subject to final order confirmation, and a sample or pre-production approval should precede volume release when fitment information is incomplete. Mark the approved sample with UD16994S, buyer application and revision date. Repeat orders should reference that same approval plus any packaging specification. If the supplier, suffix or physical design changes, treat it as a new approval rather than assuming the previous decision still applies.
