The inspection procedure for this oil jet is the same 
as for the conventional oil jet.

CRANKSHAFT OIL CLEARANCE (PLASTIGAGE 
METHOD)
The crankshaft oil clearance can be measured easily 
by using a plastigage, as follows.

AK404148AB

Plastigage

1. Remove oil and grease and any other foreign 

matters from crankshaft journal and bearing inner 
surface.

2. Install the crankshaft.
3. Cut the plastigage to the same length as the width 

of bearing and place it on journal in parallel with 
its axis.

4. Gently place the crankshaft bearing cap over it 

and tighten the bolts to the specified torque.

5. Remove the bolts and gently remove the 

crankshaft bearing cap.

AK404149

6. Measure the width of the smashed plastigage at 

its widest section by using a scale printed on the 
plastigage bag.

Standard value: 0.02 

− 0.03 mm

Limit: 0.1 mm

CYLINDER BLOCK

AK404145

1. Using a straightedge and thickness gauge, check 

the block top surface for warpage. Make sure that 
the surface is free from gasket chips and other 
objects.

Standard value: 0.05 mm
Limit: 0.1 mm

2. If the distortion is excessive, replace the cylinder 

block.

AK404146

3. Check cylinder walls for scratches and size. If 

defects are evident, replace the cylinder block.

4. Using cylinder gauge, measure the cylinder bore, 

and cylindricity. If worn badly, replace the cylinder 
block. Measurement points are shown in 
illustration.

Standard value:

Cylinder I.D. 91.10 

− 91.13 mm

Cylindricity 0.02 mm

The lubrication method is a fully force-fed, full-flow fil-
tration type. Water-cooled oil cooler built into the oil 
filter bracket have been adopted.

ENGINE OILS

HEALTH WARNING
Prolonged and repeated contact with mineral oil will 
result in the removal of natural fats from the skin, 
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful con-
taminants which may cause skin cancer. Adequate 
means of skin protection and washing facilities must 
be provided.

RECOMMENDED PRECAUTIONS
The most effective precaution is to adapt working 
practices which prevent, as far as practicable, the 
risk of skin contact with mineral oils, for example by 
using enclosed systems for handling used engine oil 
and by degreasing components, where practicable, 
before handling them. Other precautions:

• Avoid prolonged and repeated contact with oils, 

particularly used engine oils.

• Wear protective clothing, including impervious 

gloves where practicable.

• Avoid contaminating clothes, particularly under-

pants, with oil.

• Do not put oily rags in pockets, the use of overalls 

without pockets will avoid this.

• Do not wear heavily soiled clothing and oil-

impregnated foot-wear. Overalls must be cleaned 
regularly and kept separate from personal cloth-
ing.

• Where there is a risk of eye contact, eye protec-

tion should be worn, for example, chemical gog-
gles or face shields; in addition an eye wash 
facility should be provided.

• Obtain first aid treatment immediately for open 

cuts and wounds.

• Wash regularly with soap and water to ensure all 

oil is removed, especially before meals (skin 
cleansers and nail brushes will help). After clean-
ing, the application of preparations containing 
lanolin to replace the natural skin oils is advised.

• Do not use petrol, kerosine, diesel fuel, gas oil, 

thinners or solvents for cleaning skin.

• Use barrier creams, applying them before each 

work period, to help the removal of oil from the 
skin after work.

• If skin disorders develop, obtain medical advice 

without delay.
