INSPECTION AFTER INSTALLATION

Start the engine, and check for leaks of engine oil.

Stop engine and wait 10 minutes.

Check level and add engine oil as required. Refer to LU-7, "ENGINE OIL" .
Disassembly and AssemblyEBS00I4O
DISASSEMBLY
1. Remove oil pump cover.
2. Remove inner rotor and outer rotor from oil pump body.
3. Remove regulator plug, regulator spring and regulator valve.
INSPECTION AFTER DISASSEMBLY
Clearance of Oil Pump Parts

Measure radial clearance using suitable tool.

Measure side clearance using suitable tools.

Calculate the clearance between inner rotor and oil pump body
as follows.
1. Measure the outer diameter of protruded portion of inner rotor
(position 5) using suitable tool.Clearance between outer rotor and oil
pump body (position 1)
: 0.114 - 0.200 mm (0.0045 - 0.0079 in)
Tip clearance between inner rotor
and outer rotor (position 2)
: Below 0.180 mm (0.0071 in)

Side clearance between inner rotor and
oil pump body (position 3)
: 0.030 - 0.070 mm (0.0012 - 0.0028 in)

oil pump body (position 4)
: 0.030 - 0.090 mm (0.0012 - 0.0035 in)

2. Measure the inner diameter of oil pump body to brazed portion
(position 6) using suitable tool.
3. Calculate the clearance using the following formula.

(Clearance) = (Inner diameter of oil pump body) - (Outer diameter of inner rotor)
Regulator Valve Clearance
Check regulator valve to oil pump cover clearance as follows:

(Clearance) = D1 (Valve hole diameter) - D2 (Outer Diameter
of valve)
CAUTION:

Coat regulator valve with engine oil.

Check that it falls smoothly into the regulator valve hole
by its own weight.
ASSEMBLY
Installation is in the reverse order of removal.
NOTE:
Install the inner rotor and outer rotor with the punched marks on the
oil pump cover side.

Introduction of Periodic MaintenanceELS00100
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or time intervals, whichever comes first.

After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

PEDAL STROKE

When parking brake pedal is operated with the specified force, make sure the stroke is within the specified
number of notches. Check by listening and counting the ratchet clicks.
INSPECTION

Make sure the components are attached properly, checking for looseness or backlash.

Check parking brake pedal assembly for bends, damage and cracks, and replace if necessary.

Check cable for wear and damage, and replace if necessary.

Check parking brake warning lamp switch for malfunction, and replace if necessary. Refer to DI-32, "Wir-
ing Diagram — WARN —" .
ADJUSTMENT
1. Remove lower driver instrument panel. Refer to IP-13, "Instrument Lower Cover LH" .
2. Partially engage parking brake pedal to access adjusting nut.
3. Insert a deep socket wrench to rotate adjusting nut and loosen
cable sufficiently. Then, disengage the parking brake pedal.
4. Remove the wheel and tire using power tool.
5. Remove the rotor and measure inner diameter at widest point
using Tool.
6. Transfer measurement less 0.6 mm to the parking brake shoes
and adjust accordingly.
7. Using wheel nuts, secure the disc to the hub to prevent it from
tilting.
8. Rotate disc rotor to make sure there is no drag.
9. Adjust cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg,
11 0 l b ) .
b. Rotate adjusting nut with deep socket to adjust pedal stroke to
specification.
c. With parking brake pedal completely disengaged, make sure
there is no drag on the parking brake.Pedal stroke : 3 − 4 notches [under force of 196 N (20.0 kg, 44.1 lb)]

INSPECTION AFTER REMOVAL
Lining Thickness Inspection

Check thickness of lining.
Drum Inner Diameter Inspection

Check drum inner diameter.
Other Inspections

Check shoe sliding surface for excessive wear and damage.

Check anti-rattle pin for excessive wear and corrosion.

Check return spring for sagging.

Check adjuster for rough operation.

When disassembling adjuster, apply PBC (Poly Butyl Cuprysil) grease or equivalent to the adjuster
threads. Refer to MA-10, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Check either visually or with a vernier caliper to see if there is any excessive wear, cracks, or damage
inside drum.
INSTALLATION
Installation is in the reverse order of removal.

Apply brake grease to the specified points during assembly. Refer to PB-6, "COMPONENTS" .

Install adjuster so that threaded part expands when rotating it in
the direction shown by the arrow.

Shorten adjuster by rotating it in the oposite direction as shown
by the arrow.
NOTE:
After replacing brake shoes or disc rotors, or if parking brake does
not function well, perform break-in operation as follows.
1. Adjust parking brake pedal stroke. Refer to PB-3, "
ADJUST-
MENT" .
2. Perform parking brake burnishing operation by driving the vehicle forward under the following conditions:Standard thickness "A" : 5.15 ± 0.25 mm
(0.203 ± 0.010 in)
Repair limit thickness "A" : 0.5 mm (0.020 in)
