22. REMOVE NO.3 CAMSHAFT SUB-ASSY
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be held level while it is being removed. If the camshaft is not kept level, the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps should be carried out.
a. Align the timing marks (2 dot marks) of the camshaft drive and driven gears by turning the camshaft with a wrench.
b. Secure the exhaust camshaft sub-gear to the main gear with a service bolt.
Torque: 5.4 Nm (55 kgf-cm, 48 inch lbs.)
Recommended service bolt
HINT: When removing the camshaft, make certain that the torsional spring force of the sub-gear has been eliminated by the operation.
c. Uniformly loosen and remove the 10 bearing cap bolts, in several passes, in the sequence shown, and remove the 5 bearing caps and No. 3 camshaft.
NOTICE:
- Do not pry out the camshaft.
- Be careful not to damage the portion of the cylinder head receiving the shaft thrust.
23. REMOVE NO.4 CAMSHAFT SUB-ASSY
a. Uniformly loosen and remove the 10 bearing cap bolts, in several passes, in the sequence shown, and remove the 5 bearing caps and No. 4 camshaft.
NOTICE:
- Do not pry out the camshaft.
- Be careful not to damage the portion of the cylinder head receiving the shaft thrust.
b. Remove the oil seal from the No. 4 camshaft.

HINT: Attach the pins on the gears to the gear spring ends.
c. Install the wave washer.
d. Using snap ring pliers, install the snap ring.
e. Using SST, align the holes of the camshaft main gear and sub-gear by turning camshaft sub-gear counterclockwise, and temporarily install a service bolt.
SST 09960-10010 (09962-01000, 09963-00500)
f. Align the gear teeth of the main gear and sub-gear, and tighten the service bolt.
Torque: 5.4 Nm (55 kgf-cm, 48 inch lbs.)
NOTICE: Be careful not to damage the camshaft journals.
HINT: When installing the camshaft make certain that the torsional spring force of the sub-gear has been eliminated by the operation.
30. INSTALL NO.4 CAMSHAFT SUB-ASSY
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be held level while it is being installed. If the camshaft is not level the portion of the cylinder head receiving the shaft thrust may crack or be damaged, causing the camshaft to seize or break. To avoid this, the following steps should be carried out.
a. Apply new engine oil to the thrust portion and journal of the camshaft
b. Place the No. 4 camshaft at a 90° angle of timing mark (2 dot marks) on the cylinder head.
c. Apply MP grease to a new oil seal lip.
d. Install the oil seal to the camshaft.
NOTICE: Do not turn over the oil seal lip. Insert the oil seal until it stops. Remove any old packing material from the contact surface.
f. Apply seal packing to the No. 1 bearing cap as shown
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:
- Install the No. 1 bearing cap within 5 minutes after applying seal packing.
- Do not put into engine oil within 2 hours after installing.
g. Install the 5 bearing caps in their proper locations.
h. Apply a light coat of engine oil on the threads and under the heads of the bearing cap bolts.
i. Install and uniformly tighten the 10 bearing cap bolts, in several passes, in the sequence shown.
Torque: 16 Nm (163 kgf-cm, 12 ft. lbs.)
31. INSTALL NO.3 CAMSHAFT SUB-ASSY
