Bearing Housing

Check oil and coolant feed and drain ports for loose fasteners, adapters or damage to flanges, housing faces or threads which may cause fluid leakage.

Check for loose or broken turbine and compressor housing fasteners. If mounting flanges are damaged replace (or rebuild) turbocharger. Torque tighten fasteners to values specified in Holset Service Data Sheet.

CAUTION
Removal of compressor or turbine housings for inspection purposes may invalidate warranty.
