Table 41: 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). 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).
