Hella Turbocharger Actuator Worm Gear Repair Kit — Types B / C / D | Johnson 73541900
Fix Hella Turbo Actuator Failure — Replace the Worm Gear, Not the Whole Actuator.
The Hella turbocharger electronic actuator uses a worm gear to drive the wastegate rod. When the gear wears or strips, the actuator loses position control — causing boost faults, limp mode, and P0234/P0299 codes. This repair kit replaces just the worm gear — restoring full actuator function at a fraction of replacement cost.
Why Replace Just the Gear
- Targeted Fix: The worm gear is the primary wear component in Hella actuators — the motor and housing are typically fine.
- Restores Boost Control: New gear restores correct wastegate positioning and proper boost pressure.
- Major Savings: New Hella actuators cost $200–$500+. This gear costs $14.99.

Important — Identify Your Type Before Ordering: Compare your actuator's worm gear with product photos to select the correct variant (B, C, or D).
