Application and Buying Notes

Before ordering, confirm the part number 1986S10041 against the starter already fitted to the machine. The key matching points here are 12V supply, 11TH clockwise rotation, and 2 mounting bores, because a starter can look similar externally and still be incorrect for the application.

The fitment information supplied is linked to John Deere Series 6, Series 6010, Series 6020 and Series 6030 applications. If your machine is in one of those groups, compare the existing starter, mounting layout and rotation carefully rather than relying on the brand name alone.

The listed features indicate this is a heavy commercial starter motor intended for harsh environments and OE-style fit and performance.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.
