A: REMOVAL
1) Drain brake fluid from reservoir of master cylinder.
2) Remove adjusting nut and cable clamp, and disconnect
PHV cable from cable bracket on engine.
3) Detach PHV cable from clips.
4) Remove cable clamp, and disconnect PHV cable from
PHV stay.
CAUTION:
Carefully protect boots and inner cable from damage
when disconnecting PHV cable.

CAUTION:

Pay attention not to drop brake fluid onto body
painting since it may dissolve paint.

Pay attention not to damage hexagonal head of flare
nut by using pipe wrench without fail.
6) Detach PHV along with support from side frame.
CAUTION:
Exercise utmost care to prevent foreign matter from
entering into PHV when removing it.
B: INSPECTION
Check up removed parts as follows, and replace defective
ones.
1) Check if boots of PHV cable are damaged or degraded,
and if inner cable is damaged or corroded.
2) Check if return spring is worn out, damaged or cor-
roded.
3) Confirm that rolling sound of ball is heard with PHV
inclined and lever rotates smoothly.
CAUTION:
Never disassemble PHV. Replace entire PHV assembly
if necessary.
