Alternator identified by Isuzu reference 181200-6402 and Mitsubishi reference A9TU5482. Exact-number manufacturer records specify 24V, 90A, a three-groove 82 mm pulley and Isuzu 6WG1 application. Independent equipment listings also place this number family on selected Sany SY485, SY550 and SY750 machines, but those machine leads remain subject to serial verification. Four matched product views show one consistent alternator, pulley, rear connector and mounting arrangement. Confirm 181200-6402 or A9TU5482, 24V, 90A, pulley, connector, mounting and engine serial before ordering.
