A4T66686 34368-01100 24V 50A Alternator for CAT 320 / 320B / 320C

OEM / referenceA4T66686
Specification24V 50A Two-Groove Alternator
Catalog ID53572577

Mitsubishi alternator number A4T66686 cross-references to 34368-01100 for selected CAT 320-series excavator applications. An independent alternator catalog specifies 24V, 50A and a two-groove pulley, while specialist equipment records list CAT 320, 320B and 320C applications. Separate engine-family records associate A4T66686 with Mitsubishi 6D22 equipment. Five EexcavaStart-owned photos show the same two-groove alternator configuration. Earlier 55A and 60A duplicate pages are consolidated because those ratings are not supported by the reviewed exact configuration. Confirm A4T66686 / 34368-01100, 24V 50A, pulley, mounting and machine serial range before ordering.
