6008634410 Starter Motor Distributor Supply for Mixed Equipment Fleets

This reference can enter purchasing through a Komatsu excavator, a Cummins-powered industrial machine or a Case loader. The host machine and engine must remain on each quotation line so the shared starter group does not erase the buyer's actual demand.

PC128U1, 6B 5.9 and 521D applications do not justify a universal claim across every machine using those engines. Confirm the offset two-ear face, 10T drive and terminal bridge on the removed unit before stock is allocated.


 

6008634410 Starter Motor Dimensions for B2B Application Screening

The published combination is 24V, 4.5kW, 10T, module 3.175 and CW. Recording module 3.175 beside the ten-tooth count separates this starter from an eleven-tooth unit that may share the same voltage and similar housing length.

6008634410 Komatsu PC128U1 Cummins 6B 24V 4.5kW 10T starter dimensions

6008634410 Komatsu Cummins Starter Dimensions for Distributor Matching — compare the drawing with the removed starter before placing a volume order.

Use the drawing to check both Ø13 holes, the Ø89 locating reference, 46.5 mm drive position, 64 mm axial outline and unequal 42.5°/37.5° orientation. A front photograph should show which mounting ear sits highest.


 

6008634410 Starter Motor Cross-References for Parts Importers

6008634410/4510/4610, Cummins 38644320, Nikko 0240003060/3070/3240 and CST50625 variants form the main search set. Keep the machine model, engine plate and accepted two-ear view attached to the selected number.

A distributor can hold common physical stock while maintaining separate demand labels for Komatsu, Cummins and Case customers. This keeps forecasts intelligible and lets a branch identify which supported machine originally justified the inventory.


 

6008634410 Starter Motor Stock Planning for Service Distributors

For the first mixed-fleet order, inspect samples by application allocation rather than opening cartons at random. Compare pinion, mounting ears, lower terminal bridge and labels, then mark cartons so Komatsu, Case and engine-service quantities remain visible.

The Elecdura video introduces starter production and electrical testing. Multi-brand buyers can pair that supplier review with their own requirements for application labels, carton separation, sample inspection and delivery schedules for 6008634410.


 

6008634410 Starter Motor FAQs for Multi-Brand Equipment Distributors

How should a buyer identify a 6008634410 request?

State whether the requirement is for Komatsu PC128U1, Cummins 6B 5.9 or Case 521D, then add the engine plate, old-starter numbers and square photographs. Include 24V 4.5kW 10T module 3.175. This keeps a multi-application reference tied to the buyer's real machine from the first quotation.


 

Can Komatsu, Cummins and Case demand use one stock item?

A distributor may use one item after each supported application matches the same offset two-ear face, 46.5/64 mm outline, 10T drive and terminal bridge. Keep quantities and accepted photographs by machine family. This preserves common purchasing without implying that every 6B-powered or Komatsu machine uses the starter.


 

What separates the 10T 6008634410 from nearby starters?

The product combines ten teeth with module 3.175, 24V, 4.5kW and CW rotation. An eleven-tooth starter can share a similar housing and voltage but will not present the same gear interface. Count the teeth and compare pinion form before any substitute enters a mixed-equipment order.


 

Why are the 42.5° and 37.5° angles useful?

The unequal angles describe the orientation of the offset mounting ears and help determine which ear sits highest. Use them with both Ø13 holes, the Ø89 locating reference and a square front photograph. This avoids rotating or mirroring a visually similar face when comparing product images from different suppliers.


 

Does Cummins 38644320 prove the complete starter match?

No. Cummins 38644320 is a useful search reference, but the host machine, 10T module-3.175 drive, two-ear geometry and terminal arrangement must still agree. Place the Cummins number beside 6008634410 and the accepted application details so sourcing can widen without weakening the physical product definition. Record the selected host application on every reorder.


 

How should branches label shared 6008634410 inventory?

Mark 6008634410, 24V 4.5kW 10T, and the supported Komatsu, Cummins or Case application groups on the digital item. Keep the accepted two-ear image available at picking. Cartons can share the core product label while branch records preserve which machine programs have been physically compared. Review the application note before each interbranch transfer.


 

What should be sampled on the first mixed-fleet shipment?

Take units from cartons allocated to each application group and compare the rating label, ten-tooth pinion, mounting ears, lower terminal bridge and cable protection. Save front and side photographs by delivery lot. This gives receiving a common physical baseline before stock is split across equipment-service branches.


 

What should a multi-application quotation list separately?

List quantities for PC128U1, Cummins 6B 5.9 and Case 521D separately, together with engine or machine identifiers, complete references, photographs, destinations and delivery dates. Elecdura can then review one 6008634410 product while showing which customer programs create the volume, labels and shipping requirements. Identify neutral-label or split-shipment requirements in advance.
