CAMSHAFT
12. Loosen the camshaft bracket bolts in the order as shown, and
remove the camshaft brackets and camshafts.
NOTE:
Remove No.1 camshaft bracket by slightly tapping it with a rub-
ber mallet.
13. Remove the valve lifters. NOTE:
Check mounting positions, and set them aside in the order removed.
INSPECTION AFTER REMOVAL
Oil Filter
• Check that there is no foreign material on the oil filter (1) and check for clogging.
• Check the oil filter for damage.
• If there is damage, replace the oil filter.
Camshaft Runout
1. Put the camshaft on a V-block supporting the No.2 and No.5 journals.
CAUTION:
Do not support the No. 1 journal (on the side of the cam-
shaft sprocket) because it has different diameter from the
other four locations.
2. Set the dial gauge (A) vertically on the No.3 journal.
3. Turn camshaft in one direction by hand, and measure the cam- shaft runout on the dial gauge total indicator reading.
Camshaft Cam Height
1. Measure the camshaft cam height using suitable tool (A).
2. If wear is beyond the limit, replace the camshaft.

• Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu- larly.
• First aid treatment should be obtained immediately for open cuts and wounds.
• Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
• Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara- tions containing lanolin replace the natural skin oils which have been removed.
• Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
• If skin disorders develop, obtain medical advice without delay.
• Where practical, degrease components prior to handling.
• Where there is a risk of eye contact, eye protecti on should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.
ENVIRONMENTAL PROTECTION PRECAUTIONS
Dispose of used oil and used oil filters through authorized waste disposal contractors to licensed waste dis-
posal sites, or to the waste oil reclamation trade. If in doubt, contact the local authority for advice on disposal
facilities.
It is illegal to pour used oil on to the ground, down sewers or drains, or into water sources.
The regulations concerning po llution vary between regions.
Air ConditioningINFOID:0000000009463002
Use an approved refrigerant recovery unit any time t he air conditioning system must be discharged. Refer to
HA-21, "Description"
