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:
The tightening torque must be applied by two people. One person tightens socket
u
screw (25013), while the second person holds the compressor wheel (25000).
Apply tightening torque constantly, avoid jerky movements. Observe tightening torque.
u
Do not repeat the tightening of socket screw (25013).
