432-1691 Caterpillar 312E Starter Motor for Excavator Parts Dealers

An excavator breakdown request needs more than a shared C4.4 number. Stating 312E, the machine serial, C4.4 engine details and 432-1691 gives the supplier a focused quotation route and helps the dealer address delivery urgency, branch location and required packing in the same discussion.

The number family overlaps an engine-led C4.4 product, so confirm the machine identity and physical starter together. The specified product uses 24V 4.8kW, a 10T module-3.175 pinion, three Ø11 holes, Ø127 face, Ø89 locating reference and 28.5 mm drive position.


 

432-1691 24V 4.8kW Starter Drawing for C4.4 Applications

This 312E starter is defined by 24V, 4.8kW, 10T, module 3.175 and clockwise rotation. Keeping the full set beside the machine serial helps purchasing distinguish the excavator requirement from another starter that shares part of the cross-reference family.

432-1691 Caterpillar 312E C4.4 24V 4.8kW starter dimensions

432-1691 Caterpillar 312E Starter Motor Dimensions for Fleet Supply — compare the drawing with the removed starter before placing a volume order.

Compare three Ø11 holes on the Ø127 face, the Ø89 locating diameter and the 28.5 mm and 18 mm side positions. Take the removed starter's front photograph before it leaves the jobsite, with the flange square and the pinion clearly visible for dealer review.


 

432-1691 and 438000-2850 Matching for 312E Buyers

Use 432-1691 as the lead Cat identity, supported by 428000-2851, 438000-2850, S6448S and UD19273S. Keep 312E and C4.4 on the same enquiry line because the machine-led description is what separates this product from a broader engine-stock request.

Excavator dealers can plan emergency reserve by active 312E population, branch distance and previous starter consumption. A confirmed product may be shared across branches, but each transfer should retain the machine need, delivery date and full 432-1691 identity to protect jobsite picking accuracy.


 

432-1691 Starter Supply Planning for Excavator Uptime

For a jobsite-bound first order, inspect the pinion, three ears, locating face and terminal studs, then secure the heavy body against carton movement. Clear outer marks and branch allocation reduce handling delays when units move from the import warehouse directly to field-service teams.

The Elecdura production video shows starter assembly and electrical testing for export supply. Caterpillar 312E dealers can review capability while specifying first-lot tests, rugged packing, branch labels and delivery schedules for urgent and planned excavator stock.


 

432-1691 Starter Motor FAQs for B2B Buyers

Why is Caterpillar 312E the key anchor for 432-1691?

The 312E identity turns an overlapping C4.4 reference into a machine-specific buying request. State the excavator model and serial together with 432-1691, engine details and old-starter views. This lets sales address the correct 4.8kW product and the jobsite delivery requirement instead of treating every C4.4 enquiry as the same stock line.


 

How do 428000-2851 and 438000-2850 support 432-1691?

Use the complete Denso-style markings as supporting search references and keep 432-1691 as the leading Cat number. Add 312E and C4.4 to the same request. The reference group helps locate supply, while the 10T module-3.175 pinion, compact three-ear face and terminals determine the product for this excavator.


 

What does the 312E serial add to a starter quotation?

A machine serial helps define the exact host equipment, service location and parts history. It should accompany the C4.4 engine plate, 432-1691 marking and straight starter photographs. This information improves matching and gives the distributor a traceable record for urgent dispatch, branch transfer and later repeat orders for the same excavator.


 

How should a dealer plan 432-1691 stock for excavator downtime?

Review active 312E population, past starter use, branch distance, field-service response time and supplier lead time. Confirm the 4.8kW compact three-ear product before setting reserve quantities. Separating emergency units from normal replenishment shows where stock protects uptime and prevents a general C4.4 forecast from hiding jobsite urgency.


 

Which drive-end dimensions should be checked on 432-1691?

Compare three Ø11 holes on the Ø127 face, the Ø89 locating reference and 28.5 mm and 18 mm side positions. Take the photograph parallel to the flange and include the ten-tooth pinion. These measurements help a dealer judge the compact 312E product before sending units to a jobsite with limited return options.


 

What should stay with a 432-1691 branch transfer?

Carry the 312E model and serial, 432-1691 identity, 24V 4.8kW 10T rating and representative mounting and terminal images on the transfer record. Include the destination and required date. These details help the receiving branch confirm the correct excavator starter instead of accepting a shared C4.4 number without context.


 

How should a 432-1691 starter be packed for field delivery?

Support the motor body and drive housing so the starter cannot shift, protect the pinion and terminal studs, and keep the mounting face away from carton edges. Show 432-1691 and 312E outside. A strong, clearly identified carton reduces handling damage and sorting delay between the importer, regional warehouse and excavator jobsite.


 

What should a 312E dealer include in an urgent 432-1691 RFQ?

Email the 312E model and serial, C4.4 engine plate, complete 432-1691 or Denso marking, straight flange, pinion and terminal photographs, quantity, jobsite or branch destination and required delivery date. Elecdura can compare the 4.8kW configuration and return wholesale price, available production timing, packing and shipment choices.
