LOCK THE TORQUE DRIVE
Place 6 screws and 6 nuts M6 on the multi-purpose wrench. Position this wrench under the torque drive, using the pin, nut and washers to hold the assembly in place.
LOOSEN THE CLUTCH NUT
Loosen only about 1/4 turn of the clutch nut holding the clutch on the torque drive.
DISASSEMBLE THE TORQUE DRIVE THRUST SPRING
Place 3 screws and 3 M8 nuts on the multi-purpose wrench as shown in the picture below in order to exert a very slight pressure on the clutch. CAUTION: The clutch is already in the stop position, so the spring will not compress. Now the nut must be able to be unscrewed by hand. Then simply unscrew the nut from the axle to gradually release the spring. For reassembly, proceed in the reverse order of the steps described below. Tighten the nut to a torque of 115 Nm.
