Table43: Tightening torque (25013)
Always use a new socket screw (25013) and washer (25014) from the customer spare part set
(97070).
5. Fit the spinner nose cone and secure with washer (25014) and socket screw(25013). Ob-
serve tightening torque. The following must be taken into account:
u The tightening torque must be applied by two people. One person tightens socket
screw(25013), while the second person holds the compressor wheel (25000).
u Apply tightening torque constantly, avoid jerky movements. Observe tightening torque.
u Do not repeat the tightening of socket screw(25013).
6. Measure and note down distance Z between spinner nose cone and compressor wheel at
no less than three points around the circumference.
Permissible distance Z: 0.1 – 0.7 mm
Permissible difference of the measurements: ± 0.1 mm
