Application and OE Cross-Reference Review for S2057

Yanmar engine references include 3T95-L, 4T95-L, 6T95-L and related 3T/4T/6T configurations; confirm engine model and rating before order. Application data narrows the search; the complete OE number and physical starter remain the final fitment controls.

Before-Order Matching Checks for S2057

For Yanmar engine and agricultural-equipment replacement programs, confirm the old-unit label, machine or vehicle record, electrical rating, drive end, mounting face and terminals before releasing a purchase order. Keep any rating conflict or suffix difference visible in the approval file instead of hiding it in a generic product description.

Yanmar engine and agricultural-equipment replacement programs Receiving and Cost Control

Unit price is only one part of landed cost. A mixed rating, wrong pinion or unverified application can create returns, emergency freight and workshop downtime. Approve one traceable sample, record the critical identifiers and inspect incoming lots against the same baseline. Diagnose battery, cable, ground and ring-gear issues before condemning a replacement starter.

S2057 Starter Motor FAQ

Which numbers identify the S2057 starter family?

The main aftermarket reference is S2057, with 115981, S13-68, 123500-77010, 124610-77010, 124610-77019 and 20500514 appearing in public cross-reference pages. Use the exact number printed on the removed starter as the control reference. A shared family number does not remove the need to check voltage, power rating, flange, mounting holes and terminal orientation.

Which Yanmar engines are commonly listed for S2057 or 115981?

Public fitment data connects this family with Yanmar 3T95-L, 4T95-L and 6T95-L engines, with other catalogues showing closely related Yanmar industrial or marine configurations. The engine code should be confirmed because a similar-looking starter can use another rating or mounting arrangement. Ask for the engine model plate and the old starter label before approving distributor stock.

Why does the power rating need special confirmation on this item?

The supplier catalog records 12V and 3.0kW, while several independent 115981 or S2057 product pages describe 2.5kW. That is a meaningful difference for purchasing and fitment. Do not silently merge these ratings. Compare the physical sample, old-unit marking, no-load test requirement and buyer application, then lock the confirmed rating into the purchase order and receiving checklist.

What physical checks are important for the 11-tooth version?

Confirm the 11-tooth clockwise pinion, 105mm flange reference, three-hole mounting pattern and the pinion rest position reported by the approved cross-reference. Compare the locating face, bolt-hole spacing and rear connections with the removed unit. If the mounting face or terminal clocking differs, stop the approval even if S2057 and 115981 both appear on the label.

How can an agricultural distributor reduce returns?

Keep one approved sample with photographs of the drive end, flange, terminals and nameplate. Match every incoming carton and unit marking to that sample, then sample-check voltage, tooth count, rotation, mounting geometry and the confirmed power rating. Record discrepancies by lot before products are mixed into stock. This is especially important when 2.5kW and 3.0kW listings coexist under related references.

Can a 12V starter from another Yanmar model be used?

Only after the complete electrical and mechanical match is documented. Yanmar engines can use several Hitachi-style starters with similar tooth counts but different power, flange, pinion projection or terminal arrangements. Compare engine code, OE group, old-unit dimensions, rotation, wiring and ring-gear engagement. Treat a nearby model as a candidate for engineering review, not as an automatic substitute.

What should be diagnosed before replacing an S2057 starter?

Check battery state of charge, voltage during cranking, cable and ground voltage drop, the control circuit and ring gear condition. A weak battery or corroded ground can make a good starter appear defective. Record the test results and the old-unit label before authorizing a replacement. This protects the distributor from avoidable returns and gives the supplier a clear warranty record.

What should be included in a quote request?

Provide S2057 or the complete OE reference, Yanmar engine model, old-unit power marking, quantity and destination. Include clear label, drive-end, mounting-face and terminal photographs, plus any requirement for neutral packaging, private label, sample approval or receiving tests. The rating discrepancy should be resolved before price confirmation so the quotation describes one defined starter configuration rather than an ambiguous cross-reference family.
