24-volt starter motor identified by Isuzu Select Parts number 1-87618381-0 and official Isuzu genuine number 8-98070321-1. The official Isuzu Select Parts list assigns this pair to the 4HK1 engine and specifies 24 V, 5.0 kW. The exact owned front view shows a 13-tooth pinion, but tooth count, mounting flange, terminal layout, engine emission tier and serial range must still be compared with the original unit.
