Product Number: 18473N
The WAI 18473N is a brand-new 12V 1.1kW starter motor. It is built to Bosch PMGR design, replacing original-equipment numbers across Bosch, Delco Remy, Iskra / Letrika, Mahle, and Magneti Marelli references — 38 cross-references in total. It is designed for agricultural and horticultural machinery across five makes, covering Ruggerini (19 applications), Ferrari (16), BCS (11), Goldoni (11), and Bertolini (9).
The PMGR (Permanent Magnet Gear Reduction) design delivers reliable cold-start cranking from compact dimensions, making it well suited to the single-cylinder diesel and petrol engines common in Italian walk-behind tractors and compact machinery. Counter-clockwise rotation and a 9-tooth pinion ensure correct engagement with the ring gear on supported applications.
Supplied brand new — not exchange, not remanufactured — the 18473N arrives ready to fit without the core return or waiting period associated with rebuilt units.
