Product Description
Unlike standard truck starter listings, Bosch 0001340503 is more closely linked to off-highway equipment, crawler machinery, and heavy industrial engine service demand. Buyers searching this reference are usually not looking for a broad Bosch electrical part. They are more often trying to match a 24V 8.4kW 11-tooth heavy duty starter motor used in Liebherr D9508, D9512, and related heavy equipment replacement programs. Public aftermarket references also repeatedly group it with Lester 31539N, which makes it more recognizable for professional B2B sourcing.
That difference matters. In this segment, the purchasing decision is usually driven by OE number confirmation, Lester interchange, 24V system voltage, 11-tooth pinion, clockwise rotation, and the 3-hole mounting structure rather than by broad family labels alone. Public references for this Bosch group consistently show 24V, 8.4kW, 11T, CW, and 3 mounting holes, which are exactly the fitment checkpoints importers, distributors, and repair parts wholesalers usually need before quotation.
With your supplied configuration of 24V system voltage, 8.4kW output, 11 teeth, approx. 49mm pinion OD, and 92mm engagement, this 0001340503 heavy duty starter motor is suitable for buyers supporting Liebherr crawler cranes, excavators, and mining equipment service channels. Compared with highway truck starter programs, it is better suited to customers serving equipment workshops and engine-driven machine repair where downtime cost is high and accurate starter replacement is critical.
For businesses building product lines for Liebherr starter motor wholesale, Bosch OEM replacement supply, or heavy equipment aftermarket distribution, Elecdurauto can support bulk supply, fitment review, neutral packaging, and private label cooperation based on project requirements.

Yes. 0001340503 is the strongest lead OE for this starter group because public replacement references consistently connect it to Lester 31539N and to multiple Liebherr equipment applications.
The main difference is its stronger association with heavy equipment, crawler cranes, excavators, and mining-related service demand rather than standard road-truck replacement demand. Buyers usually search this OE when they need a more reliable match for Liebherr industrial equipment maintenance.
Yes. Public aftermarket references repeatedly group 31539N with Bosch 0001340503 in the same replacement family. Final confirmation should still be based on the complete starter layout and actual equipment application.
The most important points are OE number, Lester number, 24V voltage, 11-tooth pinion, clockwise rotation, and the 3-hole mounting layout. For heavy equipment applications, correct mounting and cranking specification are often more important than appearance alone.
Typical buyers include importers, heavy equipment parts distributors, repair parts wholesalers, crawler crane workshops, engine service suppliers, and regional aftermarket buyers serving Liebherr-related replacement demand.
Yes. This product is well suited to export aftermarket demand in regions where mining equipment, crawler cranes, and engine-driven heavy machinery are active. For B2B buyers, it fits workshop supply and repeated maintenance programs better than one-piece retail demand.
Yes. Neutral packaging, custom labels, and private label packaging can be arranged according to order quantity, branding requirements, and destination market needs.
The standard MOQ is 50 pcs. For repeated supply projects, annual stocking plans, or distributor orders, production and delivery schedules can be discussed based on business needs.
Because the clearest model-level public fitment signals point to Liebherr D9508, D9512, R9150, R964C, R966, R970, R974C, R976, R980 and several Liebherr crawler cranes. For navigation and SEO, Liebherr Starter Motor is the safest and strongest primary classification.
The most useful information includes the Bosch number, Lester number, equipment model, starter photos, required quantity, and any available nameplate or dimensional data. For this starter group, references such as D9508, D9512, R9150, or LR1750 are especially helpful during confirmation.
