Bell Helicopter 212 Offset Drive Assembly – Overhauled & Serviceable | P/N 212-040-208-003

Bell Helicopter Drive Assembly. Support the performance and reliability of your rotorcraft drivetrain with this

Bell Helicopter 212 Offset Drive Assembly, part number 212-040-208-003. This unit has been professionally overhauled,

remains in excellent serviceable condition, and has been properly preserved following removal. It represents a strong

maintenance solution for operators and overhaul facilities supporting the Bell 212 fleet.

The offset drive assembly is a vital mechanical component within the helicopter’s power transmission architecture. It helps

redirect rotational energy through the drivetrain, ensuring proper alignment and efficient torque transfer between connected drive elements.

Because this assembly operates under constant load and vibration, maintaining it in overhauled, serviceable condition

is essential for sustained system reliability and smooth operation.
