NB: The plastic black top, which contains the electronic control unit, is not supplied with the gear box.
NB: The plastic black top, which contains the electronic control unit, is not supplied with the gear box.

To replace the gearbox, simply remove the clips and the black plastic cover, which contains the control unit. Place the control unit on to the new Melett gearbox and reattach the clips.

When you fit the electronic actuator back onto the turbo, re-test the actuator to make sure it is working correctly using an electronic actuator tester.

To further enhance the quality of a remanufactured turbo, the complete turbo should then be flowed through an ‘air flow rig’ which ensures that the minimum vane flow settings meet with the OE specification of a new unit. The actuator can then also be tested in conjunction with the min and max air flow test which provides a report to support the quality process of remanufacture.


​As a Trade Supplier you could have full access to the detailed turbo buildsheet database, turbo catalogues, calibration information and new product releases available on our website.
