Part# 07-00771
MFR Model# BC433-H


BC433-H 30 Amp Gear-Drive Alternator for the Continental Engines (C-75 through O-300).

After many customer requests for a gear-drive alternator for Continental engines with higher output, B&C Specialty Products is pleased to present the BC433-H. Weighing only 4.4 lbs., and measuring 4 in diameter and 3.7 in installed length, the BC433-H alternator features a billet aluminum mounting flange, built-in cooling fins, and an innovative three-phase design that creates 30 amps at cruise RPM. Ships with a matching 14v three-phase regulator and 505-1 PM/OV Kit.

The BC433-H is sold less the Continental drive gear assembly (which is usually customer supplied), and requires the latest revision of the Hub (P/N 07-01327) and Retainer (P/N 07-01328).

Hello! Can you confirm the Alternator is delivered with Mounting direct to Contenantal so the only thing we need to do is to transfer the Geardrive from old Generator? Regards Kenth
