Continue with the assembly of the freewheel pulley 72Z. Slip two thrust washers
10x16x0.2
(B-P02)
onto the intermediate shaft first. Before sliding on the freewheel pul-
ley lightly lubricate the intermediate shaft. Secure the freewheel pulley with a circlip
(B-G07)
on the intermediate shaft. If both the tail pulley 48Z and the intermediate shaft
pulley 24Z are correctly assembled (no gap), you will find a minimum axial backlash
which is necessary for the smooth run of the freewheel. You need to expand the cir-
clip with special circlip pliers and then place it in the groove provided. You must not
expand the circlip too strongly since its secure fit will then no longer be guaranteed.
We proceed to the assembly of the dome bearing plate and the dome brace. In order
to avoid any twisting when assembling the chassis later on, temporarily screw the
dome brace without adding Loctite to the middle bearing plate and the dome bearing
plate. Use 4 cylinder head bolts hex M3 x 8
(B-S36)
.
The assembly of the gearing unit is completed.
