Product Number: 3905N
The WAI 3905N is a brand-new 12-volt starter motor. It is built to the Delco 50MT DD design, cross-referenced against Ford original-equipment numbers including E4HZ-11002-A and E4HZ-11002-B, as well as Caterpillar 1209100 and a wide range of Remy references. It is an OE-grade replacement for heavy plant and industrial applications where a dependable Delco-pattern motor is specified.
Manufactured to the 50MT direct-drive (DD) configuration, the 3905N runs at 12 volts with clockwise rotation and carries an 11-tooth pinion — the key dimensional and electrical characteristics buyers need to match when sourcing a replacement. Supplied brand new, it meets the original specification without requiring a core return or exchange premium.
With 30 verified OE cross-references covering Ford Engineering, Remy, AC Delco, CAT and Caterpillar part numbers, this motor is catalogue-checked across multiple supply chains, making it straightforward to confirm equivalence against an existing part number or workshop parts list.
