12V Starter Motor AT318141 for Yanmar & John Deere – Service Part
AT318141 Starter Motor, 12V, 15-Tooth Spline — replacement for Yanmar 3TNV88F / 4TNV86CT and John Deere 30G–50G compact excavators. Slow cranking, intermittent solenoid engagement, or rising current draw signals approaching end of service life; evaluating the full cranking circuit at replacement avoids repeat failures and flywheel ring gear damage. Planned maintenance supply with consolidated shipping from Guangzhou warehouse, supporting fleet-level scheduling across aging Yanmar-powered units. Replacement interval guidance and cross-reference verification included with shipment for long-term lifecycle planning.
