1987 SUZUKI GRAND VITARA seats

O-2. STANDARD SHOP PRACTICES
1. Protect painted surfaces of the body, and
avoid staining or tearing seats. When working
on fenders and seats, be sure to cover them
up with sheets.
2. Disconnect negative terminal connection of
the battery when working on any electrical
part or component. This is necessary for
avoiding electrical shocks and short-circuit-
ing, and is very simple to accomplish: merely
loosen wing nut on negative terminal and
separate cable from terminal post.
3. In raising front or rear car end off the floor
by jacking, be sure to put the jack against
differential portion of axle housing.
NOTE:
Don’t get on the car, get under it or service it in
this state.
Fig. O-3 Front Side
4. To perform service with either front or rear
car end jacked up, be sure to place safety
stands under chassis frame so that body is
securely supported. Refer to below figures
for where to place safety stands. And then
check to ensure that chassis frame does not
slide on safety stands and the car is held
stable for safety’s sake.
WARNING:
Place chocks against both right and left
wheels on the ground from both front and
rear.

3-5. INSPECTION OF ENGINE
COMPONENTS
NOTE:
During and immediately after disassembly,
inspect cylinder block and head for evidence
of water leakage or damage and, after washing
them clean, inspect more closely.
Wash all disassembled parts clean, removing
grease,slime, carbon and scales, before
inspecting them to determine whether repair
is necessary or not. Be sure to de-scale water
jackets.
Use compressed air to clear internal oil holes
and passages.
Do not disturb set combinations of valves,
bearings and bearing caps, etc. Have the
sets segregated and identified.
Cylinder Head
l Remove all carbon from combustion cham-
bers.
NOTE:
Do not use any sharp-edged tool to scrape off
the carbon. Be careful not to scuff or nick
metal surfaces when decarboning. This applies
to valves and valve seats, too.
Fig. 3-5 1
l Check cylinder head for cracks in intake and
exhaust ports, combustion chambers, and
head surface.

l Check end face of each valve stem for wear.
This face meets rocker arm intermittently
‘in operation, and might become concaved or
otherwise irregular. As necessary, smoothen
the end face with an oil stone and, if this
grinding removes the end stock by as much as
0.5 mm (0.0196 in.) (as measured from the
original face), replace the valve.
Limit on stock allowance0.5 mm
of valve stem end face(0.0196 in.)
l Check each valve for radial runout with a
dial gauge and “V” block. To check runout,
rotate valve slowly. If runout exceeds limit,
replace valve.

Valve Seats
CAUTION :
Valves to be checked and serviced for seat-
ing width and contact pattern must be those
found satisfactory in regard to stem clearan-
ce in the guide and also requirements stated
on preceding page under valves.
l Seating contact width:
Produce contact pattern on each valve in the
usual manner, namely, by giving uniform coat
of marking compound to valve seat and by
rotatingly tapping seat with valve head.
Valve lapper (tool used in valve lapping)
must be used.
The pattern produced on seating face of valve
must be a continuous ring without any break,
and width 6@ of pattern must be within
stated range as follows.

l Valve seat repair:
Valve seat not producing uniform contact
with its valve or showing width @ of seating
contact that is off the specified range must be
repaired by regrinding or by cutting and
regrinding and finished by lapping.
1) EXHAUST VALVE SEAT: Use a valve seat
cutter to make three cuts as illustrated in Fig.
3-5-16. Three cutters must be used: the first
for making 15” angle, the second for making
75” angle and the last for making 45” Seat
angle. The third cut must be made to produce
desired seat width @I!).

3) VALVE LAPPING. Lap valve on seat in two
steps, first with coarse-size lapping com-
pound applied to its face and the second with
a fine-size compound, each time using a valve
lapper according to usual lapping method.
Fig. 3-5- 18 Applying lapping compound to

NOTE:
l After lapping, wipe compound off valve face
and seat, and produce contact pattern with
marking compound. Check to be sure that
contact is centered widthwise on valve seat
and that there is no break in contact pattern
ring.
a Be sure to check and, as necessary, adjust
valve clearance after reinstalling cylinder
head and valve mechanism.

17-2. REAR SUSPENSION
GENERAL DESCRIPTION
The rear suspension consists of leaf springs, axle housing, axle shafts and shock absorbers as shown below.
The leaf springs are attached to the chassis frame through rubber bushes located at their both ends as
shown. The axle housing is installed on the right and left leaf springs by means of spring seats and U bolts.
The two shock absorbers (right & left) are installed with their lower ends attached to the spring seats
and the upper ends to the chassis frame, all through rubber bushes.

Wheel repairs that use welding, heating, or peen-
ing are not approved. All damaged wheels should
be replaced.
[Tire demounting and mounting]
Use a ‘tire changing machine to mount or de-
mount tires. Follow the equipment manufac-
ture’s instructions. Do not use hand tools or tire
irons alone to change tires as they may damage
the tire beads or wheel rim.
Rim bead seats should be cleaned with a wire
brush or coarse steel wool to remove lubricants,
old rubber and light rust. Before mounting or
demounting a tire, the bead area should be
well lubricated with an approved tire lubricant.
After mounting, inflate to 220kPa (32 psi) so
that beads are completely seated.
WARNING:
Do not stand over tire when inflating. Bead
may break when bead snaps over rim’s
safety hump and cause serious personal
injury.
Do not exceed 240kPa (35 psi) pressure
when inflating. If 220kPa (32 psi) pressure
will not seat beads, deflate, re-lubricate and
reinflate. Over inflation may cause the bead
to break and cause serious personal injury.1
Inflate to specified pressure.
[Tire repair]
There are many different materials and techni-
ques on the market to repair tires. As not all of
these work on all types of tires, tire manufactu-
rers have published detailed instructions on how
and when to repair tires. These instructions can
be obtained from the tire manufacturer.
