121254-77010 Yanmar Starter Motor Supply for Agricultural Distributors

Demand for this starter can arrive through an engine dealer, a compact-equipment branch or a John Deere parts counter. Stating the engine family and host machine beside 121254-77010 lets sales quote one physical unit while preserving quantities by customer channel and operating season.

The fifteen-tooth drive is a strong identifier, but it should be checked with 2.5kW output, module 2.54, both Ø13 holes, the Ø120 circle, 95 mm engagement and 19 mm drive position. Similar Yanmar housings may use another pinion or power level.


 

121254-77010 12V 2.5kW 15T Starter Ratings and Drive-End Data

The selected product combines 12V, 2.5kW, 15T, module 2.54 and clockwise rotation. Putting the tooth count and module beside the electrical rating on purchase orders helps receiving staff distinguish it from eleven-tooth Yanmar starters used in nearby engine families.

121254-77010 Yanmar 4T95 Starter Dimensions for Engine Distributors — compare the drawing with the removed starter before placing a volume order.

Compare both Ø13 mounting holes and the Ø120 circle from a centered front view. The side photograph should show the 95 mm engagement and 19 mm distance to the drive gear, while a terminal view confirms cable reach for the supported engine installation.


 

121254-77010 Cross-Reference Planning for Mixed Engine Orders

Use 121254-77010 as the main purchasing number. The 121254-77011, -77012 and -77019 versions, S13-41 family, 19839N and 116112 support searching; the engine and complete 15T configuration should remain attached to every quotation line.

An importer may consolidate Yanmar, Komatsu and John Deere demand only after the removed starters share the same rating, drive and two-hole face. Maintaining quantities by engine family still improves seasonal forecasting, customer service and the accuracy of replenishment decisions.


 

121254-77010 Starter Stock Support for Seasonal Equipment Demand

Agricultural distributors can plan an initial sample before the high-demand season and then place larger orders after receiving checks. Mark cartons with 121254-77010, 12V 2.5kW and 15T so branches can sort the product without opening every package.

Elecdura’s video introduces starter production and electrical testing for international supply. Buyers can review manufacturing capability while agreeing on first-lot inspection, label wording, private-label packaging and staged deliveries for mixed Yanmar and equipment-dealer demand.


 

121254-77010 Starter Motor FAQs for Agricultural and Engine Buyers

How can a buyer define 121254-77010 across Yanmar, Komatsu and John Deere demand?

Lead with the engine or machine being serviced, then add 121254-77010 and any readable suffix. Keep the selected 12V 2.5kW 15T configuration, two-hole face and terminal views in the same enquiry. This prevents a broad multi-brand reference list from replacing the physical details that an agricultural or compact-equipment buyer actually needs.


 

Which suffixes should remain visible when ordering 121254-77010?

Do not shorten 121254-77011, 121254-77012 or 121254-77019 to the base number when they appear on the old unit. Photograph every label and include any S13-41 or S13-78 marking. Complete suffixes help the supplier search the correct family, while the 15T pinion, module 2.54 and mounting dimensions confirm the selected product.


 

Why is the 15T pinion important for a 121254-77010 enquiry?

This starter is defined with fifteen teeth and module 2.54. Buyers should photograph the pinion square to the camera and count the teeth before committing a stocking order. An eleven-tooth or different-module drive may belong to another Yanmar family even when the motor body and two-hole flange appear close in a quick warehouse comparison.


 

What equipment information helps confirm a 121254-77010 starter?

Provide the Yanmar 4T95 or 4TN98 engine designation, Komatsu 3D84 details, or John Deere 3TNA82 or 4TNA82 information as applicable. Add the machine model, serial range and old-starter photographs. This gives the sales team an application path plus a physical comparison, which is more useful than sending only a mixed list of engine brands.


 

How should seasonal equipment distributors stock 121254-77010?

Review installed-machine count, pre-season service activity, previous 15T starter consumption and the time needed to replenish rural branches. Hold emergency units where downtime affects planting, harvest or rental commitments. Keep 121254-77010 stock labeled separately by the 2.5kW 15T definition so branch transfers do not mix it with other Yanmar starter families.


 

What receiving checks suit a first shipment of 121254-77010 starters?

Sample the rating labels, count fifteen pinion teeth, inspect the two Ø13 holes and compare the 95 mm engagement and 19 mm drive position with the accepted sample. Check terminal protection and carton identification as well. Recording these points gives purchasing a repeatable receiving reference before the units are distributed among engine and equipment branches.


 

What electrical checks can prevent an unnecessary 121254-77010 replacement?

Measure battery voltage under load, positive and ground-side voltage drop, solenoid signal and cable condition. Inspect the ring gear if engagement noise is reported. Include the readings with engine and starter details. A slow-crank complaint can come from resistance or battery condition, so diagnosis should accompany the request for a new 2.5kW unit.


 

What should be included in a 121254-77010 distributor RFQ?

Send the complete OE and S13 markings, engine or machine identity, 12V 2.5kW 15T label, mounting-face and terminal photographs, target quantity, annual demand, destination and required date. State whether the order serves Yanmar, Komatsu or John Deere channels. Elecdura can then discuss the defined product, volume tiers, lead time and packing requirements.
