1280005730 Construction Equipment Starter Motor for CAT 311 / 43116

For importers building a new starter range, this construction equipment starter motor serves CAT 311 / 43116 replacement demand under reference 1280005730. Its 24V system, 5.5kW rating and 10T drive help importers and distributors identify the required version before discussing volume supply.

For inventory buyers setting packaging requirements, the product is positioned for professional aftermarket supply, with product identification, fitment boundaries, inspection options and commercial terms visible before the buyer requests pricing.

1280005730 Starter Motor Specifications and Technical Drawing

For engine-parts specialists comparing the flange and terminals, the key version difference is the mounting and housing clocking. Compare 90° and 3×Ø12.5 with the old starter so the pinion alignment and cable access remain correct.

For fleet-parts buyers reviewing a replacement proposal, the source-faithful technical drawing records the available mounting information for 1280005730, including 3×Ø12.5, Ø127, 47±1 mm, 90°; use the printed values together with the product views because the drawing supports comparison and should not be scaled from the screen.

1280005730 Aftermarket Replacement and Application

For maintenance suppliers matching the unit taken from service, 1280005730, 1280005731 forms the usable OE and cross-reference group for this product, while CAT 311 / 43116 is the stated application. Cross-reference numbers help buyers find the product, but a direct replacement should still agree on voltage, output, pinion and the visible mounting configuration.

For equipment-parts dealers reviewing drive-end geometry, A direct replacement decision should combine the OE group with physical comparison. Check the mounting face, 10T drive and cable-stud direction, and ask for a separate review when one of those features differs.

1280005730 Wholesale Supply for Distributors and Importers

For purchasing teams opening a first commercial order, Elecdura supplies 1280005730 for wholesale and distributor orders with a standard MOQ of 20 pcs, an indicative 7–15 day lead time after order confirmation and an 18-month warranty under agreed terms. Neutral packaging and private-label review are available for qualified programs.

For distributors confirming an incoming batch, the order specification may include armature, solenoid, no-load or load testing together with label and packaging requirements. This gives receiving teams practical points for sampling a batch without treating appearance alone as proof of fitment.

1280005730 Starter Motor Buyer FAQ

Which specification deserves priority for 1280005730 order testing for a first bulk order?

For sales teams preparing distributor pricing, Elecdura can discuss armature, solenoid, no-load and load testing for 1280005730. State the required report format, sampling expectation and acceptance points in the RFQ. Testing should use the stated 24V and 5.5kW configuration, while identity and mounting checks remain separate because electrical results do not prove physical interchangeability.

What evidence best identifies CAT 311 / 43116 during fitment review?

For service-parts networks comparing nearby starter versions, CAT 311 / 43116 identifies the intended construction machine family, but it should not be used by itself. Pair the application with 1280005730, the 24V electrical system and the 10-tooth drive. That combination lets purchasing exclude nearby versions used on another engine build, chassis revision or equipment configuration prior to fixing the quote and shipment date.

What should purchasing verify first for 1280005730 label and suffix when confirming the commercial line?

For importers preparing a technical RFQ, photograph the complete old-unit label for 1280005730, including every prefix, suffix and separator. Shortened numbers can group starters that differ in voltage, output, drive or housing. Pair the label with a front and rear view, then retain the full marking in the RFQ and purchase order so later receiving checks use the same identity.

Which detail separates 1280005730 three-view gallery before stock is assigned?

For product managers evaluating a direct replacement, use the drive-end view to compare the pinion and flange, the side profile to judge housing length and solenoid position, and the rear view to check terminals. All three images belong to 1280005730; they should be reviewed together with the 10T drive and CAT 311 / 43116 application. Request an additional close-up when the customer's unit hides a deciding feature.

Which specification deserves priority for 1280005730 ring-gear engagement when confirming the quoted item?

For maintenance suppliers comparing the flange and terminals, review the 10T pinion, module 3.175, rest position and available axial dimensions as one engagement set. Inspect the ring gear for wear before fitting. A correct bolt pattern cannot protect the gear if pitch or projection differs, so drive geometry should be resolved before the starter is energized.

Which specification deserves priority for CAT 311 / 43116 cranking condition for a first stocking order?

For equipment-parts dealers reviewing a replacement proposal, before replacing the starter on CAT 311 / 43116, test battery state, voltage drop across positive and ground paths, the start signal and ring-gear condition. Note cranking voltage and any abnormal noise. Those observations help distinguish a supply-circuit or engine-load problem from a fault in the 24V, 5.5kW starter and make a fitment request easier to resolve.

How can an importer validate module 3.175 when checking a replacement proposal?

For purchasing teams confirming the stated application, module 3.175 is part of the gear geometry for 1280005730. Confirm it together with the 10-tooth count and pinion diameter; another module changes tooth pitch even when the number of teeth is unchanged. The old starter or ring-gear specification should therefore support the module match before a substitute is accepted.

How can an importer validate 10-tooth pinion identification before a purchase order is released?

For distributors checking application evidence, count all 10 teeth on the 1280005730 pinion and compare the gear diameter with the removed starter. Tooth count is a fast screening point, but engagement depth, pitch and rest position still need agreement. If the old unit carries another count, treat it as a different drive version and review the ring gear before fitting.
