8.4 Axial clearance

WARNING

Physical hazards due to sharp edges on compressor wheel

The compressor wheel has sharp edges which can result in injury.

Wear safety gloves.

Wear safety gloves to protect against mechanical hazards.

Screw on at least four nuts (74027) together with washers (74018),
equally spaced around the circumference, and tighten them to secure
the partition wall axially.

Measure and note the axial clearance (A).

CAUTION

Clearances out of tolerance

Clearances out of tolerance and excessively worn components can be
the cause of serious damage to machinery and property.

Have components assessed and, if necessary, replaced by an ABB
Turbocharging Service Station.
