8972251991 Isuzu 4BG1 Excavator Starter Motor Distributor

8972251991 is a 24V 4.5kW 11T CW starter motor for Isuzu 4BG1 engines in John Deere and Hitachi equipment. Its long housing is the key distinction for distributors separating related 4BG1 products.

8972251991 Long-Housing Starter Supply for Equipment Distributors

Equipment-parts buyers can search the 8972251980/1991/2001 group, but this item must remain a long-housing 8972251991 stock line. That physical distinction helps quotations, warehouse picking and remote-service orders refer to the same product.

Shared 4BG1 references and mounting dimensions do not prove that housing length or rear clearance will match. Compare the complete 1991 suffix, long body, solenoid position, cable path and old-unit side view before assigning this starter to a machine.


 

8972251991 4.5kW Ratings and 4BG1 Mounting Dimensions

This version combines 24V, 4.5kW, 11T, module 3 and clockwise rotation. Keep the output rating and long-housing description together so the product is not collapsed into a lower-output or compact version from the same OE group.

8972251991 Isuzu 4BG1 Long-Housing Dimensions for Equipment Buyers — compare the drawing with the removed starter before placing a volume order.

The two Ø13 holes, Ø120 circle, 95 mm engagement and 20 mm drive position define the front interface. A full side profile is equally important for checking body length, solenoid clearance and cable access inside the equipment compartment.


 

8972251991 Housing Verification for John Deere Hitachi Buyers

8972251991 shares S25-176, S25-177B, 114378 and New Holland references with related units. The lead suffix and accepted long-housing photographs should stay on every quote, carton and receiving report.

Construction-equipment dealers can allocate this item only to verified machines, while compact or 3.5kW versions remain separate. This protects urgent jobsite shipments from a warehouse substitution based on the shared reference list.


 

8972251991 Project Spare Support and Manufacturing Video

Packing should support the longer body and protect the nose, pinion and terminals from impact. Receiving staff can compare overall length, mounting face, 11T drive and cable side with the accepted 8972251991 sample before project allocation.

The video below introduces Elecdura starter assembly and electrical testing for export orders. It gives project buyers a view of production capability while their long-housing inspection, packing, labeling and site-delivery requirements remain product-specific.


 

8972251991 Long-Housing Starter FAQs for Equipment Buyers

Why is the long housing central to an 8972251991 enquiry?

The long housing affects machine-compartment clearance and is the clearest separator from the compact 4BG1 starter. Show the full side profile in the enquiry, not only the front face. Keep 8972251991, 24V 4.5kW, 11T and the machine identity together so purchasing receives the intended long-body configuration.


 

Which machine-compartment clearances should be photographed?

Photograph the space behind the mounting face, nearby frame or engine components, cable route and solenoid clearance. Use a ruler where overall length is tight, and include the removed starter in a matching side view. These images help confirm that the 8972251991 long housing can be installed without contact or cable strain.


 

Can the shared 4BG1 OE group prove housing interchangeability?

No. The shared 4BG1 OE group supports discovery, but it cannot prove that compact, long-housing and differently rated starters interchange. Verify the complete 8972251991 marking, 4.5kW rating, 11T drive, front dimensions and machine clearance. A separate product identity is necessary when the housing envelope changes.


 

How should overall length be checked alongside the front dimensions?

Measure overall body length from a consistent mounting reference and compare it with a full side photograph. Then verify the front hole pattern, locating diameter, pinion position and terminal orientation. For 8972251991, the front dimensions may resemble another 4BG1 starter even though the longer body changes installation clearance.


 

What packing support is appropriate for the longer starter body?

Use fitted supports that carry the longer body without loading the solenoid, terminals, mounting ears or pinion. Prevent movement inside the carton and add moisture protection for long export routes. The outer label should identify 8972251991 as the long-housing version so handlers and receiving staff do not confuse it with compact stock.


 

How should project buyers allocate commissioning and emergency spares?

Set commissioning spares from the number of machines starting service, then place emergency units where travel time or downtime risk is highest. Keep 8972251991 separate from compact 4BG1 stock at every location. Review actual project consumption before replenishing, rather than applying one spare ratio to all jobsites.


 

Which first-lot checks protect remote jobsite deliveries?

Sample first-lot units for the 4.5kW label, 11T pinion, front dimensions, long housing, terminals and packaging condition. Compare the full side profile with accepted images before dispatch to remote sites. This prevents a compact or damaged unit from reaching a machine where replacement time and transport are costly.


 

What information supports distributor terms for 8972251991?

Provide the John Deere or Hitachi machine models, 4BG1 engine details, complete 8972251991 marking, long-housing photographs, quantity by project, packing request, destination and delivery schedule. State whether staged shipments are needed. Elecdura can then quote distributor terms for the exact long-body version and project timing.


 

Request 8972251991 Isuzu 4BG1 Starter Motor Distributor Terms
