3900644 Komatsu S6D102 Starter Motor Wholesale 24V 10T

3900644 Starter Motor Wholesale for Komatsu S6D102 Service

Komatsu dealer branches and earthmoving fleets can source 3900644 for defined S6D102 installations. Because many repairs occur far from the central warehouse, the 10T pinion and 49 mm drive-end reference should be confirmed before a starter leaves for the jobsite.

Send the machine model and serial, S6D102 engine details, all readable starter numbers, front and terminal photographs, urgent quantity and destination. Elecdura can quote stock or production supply with packing suited to branch transfer or direct site delivery.

3900644 Starter Motor Dimensions for S6D102 Jobsite Fitment

3900644 Komatsu S6D102 24V 4.5kW 10T starter mounting dimensions.

The drawing shows two Ø11 holes on an offset face, with 30° and 62° angle references, an Ø89 locating diameter and an Ø127 mounting circle. Compare the 49 mm and 19 mm axial positions before accepting another S6D102 candidate.

Count the 10T module-3.175 pinion and confirm CW rotation, then inspect the solenoid and cable side. A dimensional check before dispatch is less costly than returning a starter from a remote excavator or dozer service location.

1. Search references: 3900644, 3970101, 228000-0630, 228000-1750, 228000-6640, 228000-6670, 428000-1830, 18402 and 19514 may lead to this S6D102 supply family.

2. Dispatch rule: Keep the S6D102 machine identity beside 24V, 4.5kW, 10T CW, the 49 mm drive position, two-hole offset face and terminal side. Do not dispatch on a reference-only match.

3900644 Starter Motor Branch Replenishment and Jobsite Delivery

Elecdura supports B2B orders from 20 pieces, normally 7–15 days after order confirmation, with an 18-month warranty under agreed sales terms. The delivery plan can distinguish central stock, branch replenishment and an urgent jobsite allocation.

For remote service, protect the pinion and terminals, identify the machine or branch on the carton and retain the inspected product photographs. This gives receiving teams a practical comparison even when the removed starter remains at another location.

The production video introduces Elecdura assembly and electrical testing. It helps buyers review supply capability, while final 3900644 selection remains based on the S6D102 installation, 10T drive, measured face and cable connections.

3900644 Starter Motor Questions for Komatsu Service Distributors

What should a remote-site 3900644 request include before dispatch?

Send the Komatsu machine model and serial, S6D102 engine details, every readable old-unit number and clear drive-end, side and terminal photographs. Add the jobsite, required arrival date and whether a core unit is available for comparison. These details reduce the risk of sending another 10T starter with a different face.

How does the 49 mm dimension help identify 3900644?

The 49 mm axial reference shows the drive-end position relative to the mounting face. Compare it together with the 19 mm reference, Ø89 location and Ø127 circle. Matching only the two mounting ears can miss a depth difference that affects pinion engagement even when the overall housing looks similar.

Can a Denso reference replace the Komatsu number in the purchase order?

A complete Denso number can help locate the relevant family, but keep 3900644 and the S6D102 machine details on the order. Confirm 24V, 4.5kW, 10T, CW rotation, mounting angles and terminals. The cross-reference starts the comparison; the physical unit and application finish it safely.

How should dealers plan stock for 3900644 S6D102 applications?

Review withdrawals by machine family and service branch, then separate routine replacement from downtime-critical reserve stock. Include transfer time to remote sites and the number of supported S6D102 machines. This produces a more useful replenishment quantity than combining all Komatsu starters into one annual forecast.

Which 3900644 checks belong on a receiving inspection sheet?

Record the label, 10T pinion, two Ø11 holes, 30° and 62° face, Ø89 location and terminal side. Check packaging around the pinion and cable studs. Representative arrival photographs provide a reference for branch transfers and help isolate physical differences before the starter reaches a machine.

What electrical data helps a workshop confirm starter failure?

Ask for loaded battery voltage, positive and ground voltage-drop readings and start-signal voltage during cranking. Inspect cables, grounds and ring-gear condition after removal. These checks prevent a weak battery or high-resistance connection from being misreported as a defective 3900644 starter motor during field diagnosis and parts review.

Can Elecdura support an urgent quantity and a later stock order together?

Yes. State the immediate jobsite quantity, the later branch or warehouse quantity, both required dates and the destination for each shipment. Elecdura can then quote available or production units, packing and freight separately while keeping the same verified 3900644 specification and inspection reference for dispatch.

What is needed if a 3900644 unit is reviewed after installation?

Provide the shipment lot, machine serial, installation date, operating hours, complaint and electrical test results. Add photographs of the label, pinion, mounting face and terminals from the removed and returned units. This helps separate product condition from application, installation, machine electrical or transport issues during review.
