9) Finally check clearance between pipes and/or
hoses, as shown above.
If clearance between cruise control pump and pow-
er steering hose is less than 10 mm (0.39 in), pro-
ceed as follows:
(1) Move clamped section (A) (refer to figure
above.) down to a point where pipe is close to
crossmember.
Pipe-to-crossmember clearance:
10 mm (0.39 in), min.
(2) Check that clearance between cruise con-
trol pump and power steering hose is at least 10
mm (0.39 in). If it is not, bend section (B) down
until a clearance of at least 10 mm (0.39 in) is
obtained.
(1) No interference is allowed
between hoses.
(3) Clearance between side frame
and hose: 15 mm (0.59 in) or
more
(4) Clearance between crossmember
and pipe: 5 — 13 mm (0.20 —
0.51 in)
(2) Clearance between blow-by hose
and pipe: 3 — 5 mm (0.12 — 0.20
in)
