Checking Drive Belts
1. Inspect for cracks, fraying, wear or oil. If necessary, replace
with a new one.
2. Inspect drive belt deflections by pushing midway between
pulleys.
Adjust if belt deflections exceed the limit.

Changing Oil Filter
1. Remove oil filter with a suitable tool.
WARNING:
Be careful not to burn yourself, as the engine and the engine
oil are hot.
2. Before installing a new oil filter, clean the oil filter mounting
surface on cylinder block, and coat the rubber seal of oil fil-
ter with a little engine oil.
3. Screw in the oil filter until a slight resistance is felt, then
tighten additionally more than 2/3 turn.
4. Add engine oil.
Refer to ``Changing Engine Oil'', MA-19.
Checking and Changing Spark Plugs
1. Disconnect ignition wires from spark plugs at boot.
Do not pull on the wire.
2. Remove spark plugs with spark plug wrench.
3. Clean plugs in sand blast cleaner.
4. Check insulator for cracks or chips, gasket for damage or
deterioration and electrode for wear and burning. If they are
excessively worn away, replace with new spark plugs.

Checking Manifold Tightening Torque
Checking should be performed while engine is cold
[approximately 20ÉC (68ÉF)].
Manifold bolts and nuts:
Intake
: 13 - 19 N´m (1.3 - 1.9 kg-m,9-14ft-lb)
Exhaust
: 25 - 29 N´m (2.5 - 3.0 kg-m, 18 - 22 ft-lb)
Exhaust tube nuts:
: 41.2 - 48.0 N´m (4.2 - 4.9 kg-m, 30 - 35 ft-lb)
Adjusting Intake and Exhaust Valve
Clearance
Adjustment should be made while engine is warm but not
running.
1. Set No. 1 cylinder in top dead center on its compression
stroke, and adjust valve clearance
V1,V2,V3andV6.
2. Set No. 4 cylinder at top dead center on its compression
stroke, and adjust valve clearance
V4,V5,V7andV8.
Valve clearance:
Intake
V1,V3,V5andV7
0.30 - 0.40 mm (0.012 - 0.016 in)
Exhaust
V2,V4,V6andV8

Adjusting screw lock nuts:
: 15 - 20 N´m (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
lTighten lock nuts, by fixing the adjusting screws using a
minus driver.
Checking Drive Belt
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check drive belt deflection by pushing on the belt midway
between pulleys.
Adjust if belt deflections exceed the limit.

3. Check spray pattern by pumping tester handle one full stroke
per second.
a. If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates
from main spray (pattern B).
4. If initial injection pressure or injection nozzle is not normal,
adjust or clean injection nozzle.
5. Test again. If it is not corrected, replace nozzle.
Refer to EC section for injection pressure adjustment, clean-
ing and replacement.
6. Install all injection nozzles with Tool and securely connect
fuel spill tube and delivery tubes.
7. Bleed air from fuel system and check for fuel leakage with
engine running.
Injection nozzle to cylinder head:
:54-64Nzm (5.5 - 6.5 kg-m, 40 - 47 ft-lb)
Spill tube nut:
:29-39Nzm (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
Injection tube:
:20-25Nzm (2.0 - 2.5 kg-m, 14 - 18 ft-lb)
Checking Idle Speed
Preparation
1. Make sure that injection timing is correct.
2. Make sure that injection nozzles are in good condition.
3. Make sure that the following parts are in good condition.
lAir cleaner clogging
lGlow system
lEngine oil and coolant levels
lValve clearance
lAir intake system (Oil filler cap, oil level gauge, etc.)
4. Set shift lever in ``Neutral'' position. Engage parking brake
and lock both front and rear wheels with wheel chocks.
5. Turn off air conditioner, lights and accessories.
6. Make sure that idle control knob is fully released and idle
adjusting screw contacts accelerator control lever.
