The axial clearance between the nuts and the upper
end
piece
of the
spring
must
he
within 0.2 and 0.5 mm
.
M<1ke

R.EPAIR.ING THE FR.ONT FOR.K COMPONENT
PAR.TS
Clearances
and interferences
for the
mating
members
are given
in Table II.
The maximum permissible
va
lu
es of wear
and
clearances
in
the
basic mating members
are
presented in Table
12.
The front fork has to be repaired in
case
any faults
are
detected
rendering impossible the further usage of the fork,
a
nd
also
in
the
case of a total disassembly or reconditioning of the
entir
e
motor-
cyc
le.
Inspect
a
ll
the
component
parts and mating
su
rfac
es
.
Check the
following:
front fender and
casings
for the absence of cracks
a
nd
mechani-
cal damage; eliminate the detected
fault
s and,
if necessary, paint the
repaired surfaces;
traverse
and bridge for the absence of cracks,
breaks
or
bending
(replace the
defective
parts);
fork
leg
bushings
for
the absence of cracks,
chipped
