Removing and stripping the epicyclic hub assem-
bly
Undo the three bolts (Silver 100.6 machines) securing the planet
carrier housing B (fig 10) to the halfshaft (on all other Silver
models, the spacer has just one bolt at centre).
Screw puller p/n 5.9030.618.4/10 (fig 11) to the locking spacer A,
interposing a reducer if necessary.
Remove the spacer and the flange, and recover the shims behind.
Remove the epicyclic unit and separate into component parts,
proceeding as follows:
1 - Using a hammer and punch, drive out the pin by which each
shaft A is retained in the relative planet wheel B (fig 12).
2 - Remove the shaft and separate the planet wheel together with
the needle bearing and the two thrust washers.
3 - Remove the bearing A from the flange of the epicyclic unit B,
using a suitable puller (fig 13).
