Note 1: Ring spring 7 inevitably loses its elasticity when removed from Spindle. This will also happen to new one when
it is assembled to Spindle. Therefore, reuse removed Ring spring 7 if it is not damaged.
Do not forget to fasten Ring spring 7 securely to Spindle using pliers whether it is removed one or new one.
Note 2: Do as described in Fig. 17 when assembling Lock spring 16 and Lock sleeve to Large spiral bevel gear.
Do the reverse of the disassembling steps.

then tap the top of the spring with plastic hammer
while gradually moving the impact point counterclockwise
until the spring does not move any further.
Put Lock sleeve over Lock spring 16, then tap the top
of the sleeve with plastic hammer as illustrated below
