Engine Oil and Filter Change
WARNING:
New and used engine oil can be hazardous.
Be sure to read ªWARNINGº in General Precaution in Sec-
tion 0A and observe what in written there.
Before draining engine oil, check engine for oil leakage. If any evi-
dence of leakage is found, make sure to correct defective part be-
fore proceeding to the following work.
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall drain plug, and
tighten it securely as specified below.

NOTE:
Before fitting new oil filter, be sure to oil its O-ring. Use engine
oil for this purpose.
4) Screw new filter on oil filter stand by hand until the filter O-ring
contacts the mounting surface.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position at which at filter O-ring first contacts
the mounting surface.
5) Tighten the filter 3 / 4 turn from the point of contact with the
mounting surface using an oil filter wrench.

6) Replenish oil until oil level is brought to FULL level mark on dip-
stick. (oil pan and oil filter capacity). The filler inlet is at the top
of the cylinder head cover.
It is recommended to use engine oil of SG, SH or SJ grade.
NOTE:
For temperature between ±20C (±4F) and 30C (86F), it
is highly recommended to use SAE 10W ± 30 oil.

CLEARANCE BETWEEN BOOSTER PISTON ROD AND
MASTER CYLINDER PISTON ADJUSTMENT
The length of booster piston rod is adjusted to provide specified
clearance ªaº between piston rod end and master cylinder piston.
Before measuring clearance, push piston rod several times so as
to make sure reaction disc is in place.
Keep inside of booster at atmospheric pressure for measure-
ment.
1) Set special tool (A) on master cylinder and push pin until con-
tacts piston.
Special Tool
(A): 09950-96010
2) Turn special tool upside down and place it on booster. Adjust
booster piston rod length until rod end contacts pin head.
Special Tool
(A): 09950-96010
Clearance ªbº: 0 mm (0 in.)
NOTE:
Take measurement with booster set vertically and rod at the
center.
3) Adjust clearance by turning adjusting screw of piston rod.
Special Tool
(F): 09952-16010
Reference
When adjusted as above, its negative pressure is applied to boost-
er with engine at idle, piston to piston rod clearance ªaº should be-
come below.
