diagnostic procedures of this manual.

HT4B/4C/80 turbochargers weigh up to 60 kg (132 lb) and turbine housing weight is greater than

20 kg (45 lb).

Caution

This turbocharger has been manufactured using piece part and rotor balance processes and MUST be check

balanced on rebuild.

If you intend to overhaul/repair a rotor balanced turbocharger, ensure that all the rotor parts have co-relation

marks prior to disassembly so that they can be reassembled in the same relative positions.

Balance limits for turbocharger rebuild are shown on Holset’s Service Data Sheet. with the exception of HX83

which requires a unique balancing process available through an approved Holset agent.

It is important to note that operating a turbocharger with a rotor or core balance level greater than the

published limits could cause turbocharger or engine failure. If you are in any doubt regarding the balancing

process, please contact an approved Holset agent for assistance.

Warning

Some parts are manufactured in fluoroelastomers (e.g. Viton) or similar that requires special treatment in the

case of repair and service after fire.
