• Securely clamp brake lines with PVC coated

clamps or grommets to prevent vibrations when
the vehicle is running.

• The standard brake line clearances are shown in

the table below.

Unit: mm {in.}

• Brake lines should be laid along the inside web of

the side rail whenever possible. When they cross
over to the opposite side rail, they should be
positioned along the crossmembers.
Install the lines more than 10 mm {0.39 in.} away
from bolts and rivets.

• Make sure the brake fluid lines can be bled easily.
• Never clamp or tape electrical wires to the brake

lines, as this can cause corrosion of the line.
Maintain the clearances described in Section 7
"Clearance between chassis parts and bodies"
컄 page 119.

• The clearance between the brake lines and exhaust

system components should conform to the
specifications in Section 7 "Clearance between
chassis parts and bodies"

컄 page 119.

• Position the connection nut in a location where it

can be completely tightened without difficulty.

• Tighten the flare nuts to torque specified in

컄 page 90. Do not tighten the flare nut any further
if oil leaks. Loosen the flare nut completely, adjust
the mating surfaces, re-thread the nut and then
tighten it completely.

• Never force or tighten any part with a wrench or

other tool if problems occur while installing brake
lines. Realign the brake lines so the mating
surfaces are correctly positioned, and then tighten
the flare nut. If possible, first gently thread the nuts
by hand, and then tighten them with the
designated flare nut wrench.

• Never install brake lines near the drive shaft or

other moving parts.

• Never change the installation location of the brake

hoses.

• When replacing the brake lines, do not use the fluid

which was drained.
Drain the fluid completely and replace with new
fluid.

• Install the brake lines so that they are protected

from damages caused by flying objects thrown up
by the tires.

• When it is necessary to protect brake lines against

possible damage as described above, install a
protective panel as shown below.
(a) Fabricate a protective panel which will not be

deformed by flying objects and come in contact
with the brake lines.

(b) Position and shape the protective panel

properly (for drain holes, etc.) so water will
drain freely.

6.7 Modifications to the wheelbase

The wheelbase should not be extended or shortened
because considerations for the propeller shaft length,
balancing, position of center bearings, brake piping
and harness lengths are required.

If this is unavoidable, contact the department
responsible

컄 page 15.

6.7.1

Prohibition on modifying the propeller
shaft

a

Risk of accident

It is strictly prohibited to modify a propeller shaft by
welding or other means to change its length.

An improperly modified propeller shaft may cause
vibration during operation, which in turn may cause
cracks and fractures in the clutch housing,
separation of the propeller shaft, and other
dangerous conditions, possibly resulting in injury,
or death.

6.8 Frame modifications

• The maximum permissible axle loads must not be

exceeded, while the minimum front axle load must
be met or exceeded.

• Rear underride guard: fastened in the same way as

on a standard vehicle.

• Extend the mounting frame to the end of the frame.

6.8.1

Extension and shortening

Procedure for extending the frame’s rear
overhang

Extend the frame’s rear overhang as follows.

• Materials

Unit: mm {in}

As high tensile strength steel (540 MPa class)
hardens more easily at welds than automotive
structural steel (SAPH440), follow the instructions
below.

(a) Be sure to use a low-hydrogen type electrode.

Especially, where the weld must have the same
strength level as the base metal, use a low
hydrogen, high tensile strength type electrode.

(b) Short weld beads are more likely to crack due to

low hardening rate, so in areas requiring many
short weld beads, perform continuous welding
instead.

• Extension/shortening procedure

Follow the reinforcement method described below.

When bolts are used for fastening the
reinforcement, fasten it at two or more points to
each of the frame and extension member. Use M10
bolts (8T) and nuts (6T) and tighten them to a
torque of 60 to 80 N-m {44 to 59 ft-lbs., 6.1 to 8.2
kgf-m}.

Finish flange ends at butt welds of the side rail with
particular care using a grinder so that there is no
undercut or build-up of weld metal. Also make sure
that there is no difference in level between the side
rail and extension member. If there is a step
between them, finish the area for a smooth
surface.
