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)
