Product Description
Unlike broader heavy equipment starter listings, this product page is built around 600-813-3632 demand from buyers who are trying to match a specific Komatsu S6D125 starting configuration used in PC300 and PC400 equipment channels. In most cases, distributors and importers searching this reference are not looking for a generic construction starter. They are working from an OE number, a Nikko cross reference, or an engine-based replacement requirement tied to fleet maintenance and equipment downtime recovery.
That distinction matters in B2B purchasing. For this type of heavy duty starter motor, buyers usually confirm the order by OE number, application, and core installation data rather than by starter family name alone. Public cross-reference listings consistently connect 600-813-3632 with 0-23000-8300, and aftermarket references also associate this unit family with Lester 18107, making part-number accuracy essential for quotation and stock planning.
Based on your supplied product sheet, this version is configured with 24V system voltage, 8.5kW output, 12 teeth, 46 mm pinion OD, and 92 mm engagement. Public application listings place this reference in Komatsu-related equipment channels including PC300, PC400, PC400-3, PC650, PC1600, GD605A, GD623A, and HD205-3 type applications, which makes it relevant for buyers supporting excavator, grader, and track loader aftermarket demand.
For companies building a replacement line for Komatsu construction equipment, Elecdurauto can support MOQ 20 pcs, OE-grade aftermarket supply, neutral packaging, and private label cooperation for importers, distributors, and regional wholesalers.

Yes. 600-813-3632 is the main Komatsu OE reference used as the lead identifier for this product. In public aftermarket cross-reference sources, it is frequently linked with Nikko 0-23000-8300, and Lester 18107 also appears in related catalog paths. For B2B quotation, keeping the main OE number at the front is the best way to improve search accuracy and purchasing efficiency.
This page is built around a specific S6D125 replacement requirement, not a broad or generic Komatsu starter category. It is structured for buyers who search by 600-813-3632, 0-23000-8300, Komatsu PC300 starter motor, or Komatsu PC400 starter motor, and need core data aligned with bulk purchasing and aftermarket stock planning.
Public cross-reference listings repeatedly associate this unit with 0-23000-8300, and aftermarket sources also show Lester 18107 in the same reference path. For importers and distributors, that makes these numbers useful search terms during sourcing and catalog matching. Final order approval should still be based on OE number, engine model, and original-unit comparison when needed.
That happens because public aftermarket data for the 600-813-3632 family is not always normalized across sellers and catalogs. Some listings describe the family as 7.5kW, while other indexed product data matches your provided spec of 24V 8.5kW 12T. For this reason, this page follows your supplied product sheet for the main selling specification and uses public sources only for cross-reference and application expansion.
Buyers should confirm 600-813-3632 / 0-23000-8300, Komatsu S6D125 application, 24V system voltage, 12-tooth pinion, 46 mm pinion OD, and 92 mm engagement. If your market requires stricter replacement control, it is also practical to confirm mounting shape, solenoid position, and original unit photos before mass purchase.
This model is typically relevant to aftermarket importers, construction equipment parts distributors, regional wholesalers, and buyers supporting Komatsu excavator and grader repair channels. It is especially suitable for companies maintaining repeat stock for PC300, PC400, GD605A, and other S6D125-related service demand.
Yes, it can be suitable for those regions when buyers source by OE number and established Komatsu application. Because public listings connect this reference to multiple Komatsu excavator, grader, and track loader models, it is relevant for regional replacement programs where S6D125 equipment remains active in the field. Fitment approval should still be tied to the exact reference and original configuration.
Yes. Elecdurauto can support neutral packaging, brand packaging, and project-based private label cooperation for qualified B2B buyers. This is suitable for importers, distributors, and customers building their own aftermarket starter motor line.
The standard MOQ is 20 pcs. This is suitable for buyers who are testing a market, building regional stock, or preparing trial volume for long-term wholesale cooperation.
For faster quotation approval, buyers should send the OE number 600-813-3632, any cross reference such as 0-23000-8300, the engine model S6D125, target application such as PC300 / PC400, and any available photos of the original starter. That helps reduce interchange risk and improves bulk-order accuracy.
