6.Fit the keys (8400) into the rotor shaft (0701). Be care- ful that the keys (8400) are not hitting the shaft sleeve (8350-B) during assembly.

7.Fit rear axial bearing holder (8350-D) on the rotor shaft (0701).

8.Place spring washer (8500) on the rotor shaft (0701) as indicated on the sketch and screw on locking nut (8510).

9.Place the assembly vertically on the work bench and lock the rotor by pushing a copper bar through the rotor teeth.

10.Tighten locking nut (8510) until the shaft nut makes contact with the axial face of the rear axial bearing holder (8350-D).

11.Check the axial bearing clearance using a feeler gauge (see table below).

TG MAG	Axial clearance
	[mm]
15-50	0.11 – 0.13
23-65
58-80	0.13 – 0.15
86-100
185-125	0.15 – 0.18

12.Tighten set screws (8520) to secure the locking nut (8510).

13.Mount the inner magnetic rotor (8310) on the hub of the rear axial bearing holder (8350-D). Make sure that the locking pins are falling into the holes of the inner magnetic rotor (8310).

14.Screw in cap head screws (8490) and tighten them (with Loctite 243) crosswise with the specified torque (see Chapter 3.21.3.1) to fix the inner magnetic rotor (8310) on the hub.

15.Check if the rotor shaft (0701) can be turned by hand evenly and without remarkable resistance.
