Product Number: 19805N
The WAI 19805N is a brand-new 24V starter motor. It is built to DENSO specification, designed to replace the original DENSO unit (428000-1120) on a wide range of Caterpillar and Barber Greene plant machinery. With 121 Caterpillar and 8 Barber Greene applications covered, it is a direct-fit replacement for operators keeping heavy construction and paving equipment in service.
Supplied in brand-new condition, the WAI 19805N is manufactured to DENSO engineering standards and carries a Lester reference of 19805, making cross-referencing against workshop data straightforward. The 24V rating suits the electrical systems common to larger plant machinery, where reliable cranking performance under demanding conditions is essential.
Fitment spans a broad range of models, including the Barber Greene BG225C, BG230D, BG500E and BG555E, and Caterpillar machines such as the 312D 2, 312D GC, 313D 2 LGP and 313D 2 — covering production years from 1998 through to 2024. Always verify your exact model, engine variant and year against the application list before ordering.
