(g) Install the seal washer and screw plug.
Torque: 15 N´m (150 kgf´cm, 11 ft´lbf)
8. INSTALL CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being installed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Set the crankshaft pulley position.
Turn the pulley clockwise or counterclockwise, and align
the timing mark of the crankshaft pulley with the centers
of the crankshaft pulley bolt and idler pulley bolt.
NOTICE:
Having the crankshaft pulley at the wrong angle can cause
the piston head and valve head to come into contact with
each other when you install the camshaft, causing dam-
age. So always set the crankshaft pulley at the correct
angle.
(b) Install the LH camshafts.
(1) Apply MP grease to the thrust portion of the intake
and exhaust camshafts.
(2) Align the timing marks (2±dot mark) of the camshaft
drive and driven main gears, and place the intake
and exhaust camshafts.
(3) Apply seal packing to the camshaft housing plug.

Remove the old packing material (FIPG).

Apply seal packing to the housing plug.
Seal packing: Part No. 08826±00080 or equivalent

18. REMOVE REAR OIL SEAL RETAINER
(a) Remove the 7 bolts.
(b) Using a screwdriver, remove the oil seal retainer by prying
the portion between the oil seal retainer and main bearing
cap.
(c) Remove the O±ring.
19. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while mov-
ing the connecting rod back an forth.
Standard thrust clearance:
0.160 to 0.290 mm (0.0063 to 0.0114 in.)
Maximum thrust clearance: 0.35 mm (0.0138 in.)
If the thrust clearance is greater than maximum, replace the
connecting rod assembly(s). If necessary, replace the crank-
shaft.
Connecting rod thickness:
22.880 to 22.920 mm (0.9008 to 0.9024 in.)
20. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Check the matchmarks on the connecting rod and see it
cap to ensure correct reassembly.
(b) Remove the 2 connecting rod cap bolts.
(c) Using the 2 removed connecting rod cap bolts, remove
the connecting rod cap and lower bearing by wiggling the
connecting rod cap right and left.
HINT:
Keep the lower bearing inserted with the connecting rod cap.
(d) Clean the crank pin and bearing.
(e) Check the crank pin and bearing for peeling and
scratches.
If the crank pin or bearing is damaged, replace the bearings. If
necessary, replace the crankshaft.

(f) Lay a strip of Plastigage across the crank pin.
(g) Install the connecting rod cap with the 2 bolts.
(see page EM±119)
NOTICE:
Do not turn the crankshaft.
(h) Remove the 2 bolts, connecting rod cap and lower bear-
ing. (See procedure (b) and (c) above)
(i) Measure the Plastigage at its widest point.
Standard oil clearance:
0.021 to 0.047 mm (0.0008 to 0.0019 in.)
Maximum oil clearance: 0.059 mm (0.0023 in.)
If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, replace the crankshaft.
HINT:
If using a standard bearing, replace it with one having the same
number. If the number of the bearing cannot be determined, se-
lect the correct bearing by adding together the numbers im-
printed on the connecting rod cap and crankshaft, then select-
ing the bearing with the same number as the total. There are 6
sizes of standard bearings, marked º2º, º3º, º4º, º5º, º6º and º7º.
