INSTALL CAMSHAFTSFig. 25 Cylinder Head Bolt Tightening Sequence:
NOTICE: Since the thrust clearance of the camshaft is small, the camshaft must be held level while it la being in- stalled. 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 step:e should be carried out.
Install intake camshaft of RH cylinder head
Fig. 26 Seal Packing Locations:
(a) Apply MP grease to the thrust portion of the camshaft.Fig. 26.

Note:Installing the front bearing cap will determine the thrust position of the camshaft. Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
Install Brg. Caps:
(f) Install the other bearing caps in the sequence shown with the arrow mark facing rearward.
Note: Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
Bearing Cap Bolts:
(g) Apply a light coat of engine oil on the threads and under the heads (A only) of the bearing cap bolts.
note: Do not apply engine oil under the heads of the bearing cap bolts (B).
(h) Install a new seal washer to the bearing cap bolt (B). Install the eight bearing cap bolts as shown.
Note:Use bearing cap bolts 38 mm (1.50 in.) in length. The bolts are black (A) or silver (B) in color. Install the two silver bolts to the front bearing cap. Install the six black bolts to the other positions. After installing the oil feed pipe, install the two bolts to the rear bearing cap as directed in step B (I).
(i) Uniformly tighten the eight bearing cap bolts in several passes, in the sequence shown.Torque: 160 kg-cm (12 ft-lb, 16 N~m)
Install exhaust camshaft of RH cylinder head
Install Exhaust Cam Rt. Head:
(a) Set the timing mark (one pointed mark) of the camshaft drive gear at 10 degree angle by turning the intake camshaft with a wrench.
(b) Apply MP grease to the thrust portion of the exhaust camshaft.
Align Timing Marks:
(c) Align the timing marks (one pointed mark) of the camshaft drive and driven gears.
(d) Place the exhaust camshaft on the cylinder head.
(e) Check that the exhaust camshaft moves smoothly in the thrust direction.
(f) Install the rear bearing cap with the arrow mark facing rearward.
note:Installing the rear bearing cap will determine the thrust position of the camshaft. Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
(g) Install the other bearing caps in the sequence shown with the arrow mark facing rearward.
note: Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
(h) Apply a light coat of engine oil on the threads and under the heads of the bearing cap bolts.
(i) Install the oil feed pipe and ten bolts.
note: Use bearing cap bolts 38 mm (1.50 in.) and 52 mm (2.05 in.) in length. Use black colored 38 mm (1.50 in.) bolts. Install the two 52 mm (2.05 in.) bolts on the outside positions of the oil pipe. Install the eight 38 mm (1.50 in.) bolts on the other positions.
(j) Uniformly tighten the eight bearing cap bolts on the bearing caps of the exhaust camshaft in several passes, in the sequence shown. Torque: 160 kgcm (12 ft-lb, 16 N~m)
(k) Alternately tighten the two bearing cap bolts on the rear bearing cap of the intake camshaft in several passes. Torque: 160 kg-cm (12 ft-lb1 16 N.ml
(l) Bring the service bolt installed in the driven sub-gear upward by turning the camshaft with a wrench.
(m) Remove the service bolt.
Install intake camshaft of LH cylinder head
(a) Apply MP grease to the thrust portion of the camshaft.
(b) Place the intake camshaft at 60 degree angle of the timing mark (one pointed mark) on the cylinder head.
(C) Remove any old packing (FIPG) material.
(d) Apply seal packing to the bearing cap (mark l1) as shown. Seal packing: Part No.08826-00080 or equivalent
(e) Install the front bearing cap (mark "l1 up) with the arrow mark facing forward.
note:Installing the front bearing cap will determine the thrust position of the camshaft. Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
(f) Install the other bearing caps in the sequence shown with the arrow mark facing forward.
note: Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
(g) Apply a light coat of engine oil on the threads and under the heads (A only) of the bearing cap bolts.
note: Do not apply engine oil under the head8 of the bearing cap bolts (B).
(h) lnstall a new seal washer to the bearing cap and install the eight bearing cap bolts as shown.
Note:Use bearing cap bolts 38 mm (1.50 in.) in length. The bolts are black (A) or silver (B) in color. Install the two silver bolts to the front bearing cap. Install the six black bolts to the other positions. After installing the oil feed pipe, install the two bolts to the bearing cap second from the front as directed in step D (i).
(i) Uniformly tighten the eight bearing cap bolts in several passes, in the sequence shown.Torque: 160 kg-cm (12 ft-lb, 16 N~m)
Install exhaust camshaft of LH cylinder head
(a) Set the timing mark (two dot marks) of the camshaft drive gear at 15 degree angle by turning the intake camshaft with a wrench.
(b) Apply MP grease to the thrust portion of the exhaust camshaft.
(c) Align the timing marks (two dot marks) of the camshaft drive and driven gears.
(d) Place the exhaust camshaft on the cylinder head.
(e) Check that the exhaust camshaft moves smoothly in the thrust direction.
(f) Install the front bearing cap with the arrow mark facing forward.
Note:Installing the front bearing cap will determine the thrust po8ition of the camshaft. Align the arrow mark8 at the front and rear of the cylinder head with the mark on the bearing cap.
(g) Install the other bearing caps in the sequence shown with the arrow mark facing forward.
Note:Align the arrow marks at the front and rear of the cylinder head with the mark on the bearing cap.
(h) Apply a light coat of engine oil on the threads and under the heads of the bearing cap bolts.
