Product Overhaul

Turbocharger overhaul takes place in the Napier factory where we remanufacture complete turbochargers or cartridges to OEM standards.

Napier currently offer factory overhaul for the following frame sizes – NA295, NA355, NA297, NA307, NA357, NA397, NA457, NA298, NA358, NT Series

During the overhaul, the units are stripped down and analysed to assess where parts may need to be repaired or replaced to achieve ‘as new’ operating efficiencies.

Overhauling products in this way helps to reduce your costs and maintain the highest levels of performance. Napier overhaul department use factory approved salvage techniques as cost effective alternatives to replacing some components that can wear.
