• Place the motor onto the gearbox and guide the wires through the holes into the gearbox.
• Make sure that the motor’s shaft fits correctly into the splines of the coupling.
!
Do NOT tighten the assembling bolts of the motor before the motor fits correctly and
straight in the flange of the gearbox. There is a risk to damage or misplace the inner circlips
of the coupling when using force.
• Rotate the motor shaft by hand. Make sure the shaft rotates freely and that the drive pinion of the
gearbox rotates simultaneously.
• Tighten the motor fixing bolts to the correct torque.
• Assemble the friction plate (6). Text "REIBSEITE" must be against the friction disc (4) (if applicable).
• Assemble the brake disk and the brake. Do not tighten the brake fixing bolts yet, the shaft should be
able to rotate freely.
• Insert the motor-gearbox subassembly into the drum
