Valve Stem-to-Guide Clearance Inspection

Installation

1. Valve Seal

1. Install the new valve seals (A) using the 5.5 mm side of the stem seal driver (B).

NOTE: The exhaust valve seal (C) has a black spring (D), and the intake valve seal (E) has a white spring (F), they are not interchangeable.

2. Install the valve spring compressor attachment and the valve spring compressor.

3. Compress the spring and install the valve cotters.

4. Remove the valve spring compressor and the valve spring compressor attachment.

5. Lightly tap the end of each valve stem two or three times with a plastic mallet (A) to ensure proper seating of the valve and the valve cotters. Tap the valve stem only along its axis so you do not bend the stem.

NOTE: Be sure to raise the head off the work bench so the valve is not possibly damaged.

3. Camshaft

1. Install the camshaft (A).

2. Install the camshaft thrust cover (B) with a new O-ring (C).

4. Camshaft Sprocket

1. Install the camshaft sprocket.

2. Apply new engine oil to the threads of the camshaft sprocket mounting bolt.

3. Install the camshaft sprocket mounting bolt.

4. Hold the camshaft with a 27 mm open-end wrench.

5. Tighten the camshaft sprocket mounting bolt.

5. Rocker Arm Assembly

1. If the rocker arm assembly is disassembled, reassemble the rocker arm assembly.

2. Install the oil control orifice (A) with a new O-ring (B).

5. Tighten each bolts two turns at a time in sequence.

6. Cylinder Head Assembly

1. Clean the cylinder head and the engine block surface.

2. Install a new coolant separator (A) in the engine block whenever the engine block is replaced.

3. Install the new cylinder head gasket (B) and the dowel pins (C) on the engine block. Always use a new cylinder head gasket.

4. Install the cylinder head on the engine block.

5. Measure the diameter of each cylinder head bolt at point A and point B.

6. If either diameter is less than 10.6 mm (0.417 in), replace the cylinder head bolt.

7. Apply new engine oil to the threads and under the bolt heads of all cylinder head bolts.

8. Torque the cylinder head bolts in sequence to 40 Nm (4.1 kgfm, 30 lbfft). Use a beam-type torque wrench. When using a preset click-type torque wrench, be sure to tighten slowly and do not overtighten. If a bolt makes any noise while you are torquing it, loosen the bolt and retighten it from the first step.

9. After torquing, tighten all cylinder head bolts in two steps (90 ° per step using the sequence shown in step 8). If you are using a new cylinder head bolt, tighten the bolt an extra 60 °.

NOTE: Remove the cylinder head bolt if you tightened it beyond the specified angle, and go back to step 5 of the procedure. Do not loosen it back to the specified angle.

7. Cam Chain

1. Install the cam chain on the crankshaft sprocket with the colored piece (A) aligned with the mark (B) on the crankshaft sprocket.

2. Install the cam chain on the camshaft sprocket with the colored link plate (A) aligned with the mark (B) on the camshaft sprocket.

3. Install the cam chain guide (A) and the cam chain tensioner arm (B).

8. Cam Chain Auto-Tensioner

1. Compress the cam chain auto-tensioner when replacing the cam chain. Remove the pin (A) from the auto-tensioner that was installed during removal. Turn the plate (B) counterclockwise, to release the lock, then press the rod (C), and set the first cam (D) to the first edge of the rack (E). Insert the 1.0 mm (1/32 in) diameter pin back into the holes (F).

NOTE: If the chain tensioner is not set up as described, the tensioner will be damaged.

2. Install the cam chain auto-tensioner.

3. Remove the pin from the cam chain auto-tensioner.

9. Engine Oil Pump Assembly

1. Check the oil pump oil seal for damage. If the oil seal is damaged, replace the oil seal.

2. Remove all of the old liquid gasket from the oil pump mating surfaces, the bolts, and the bolt holes.

3. Clean and dry the oil pump mating surfaces.

4. Apply liquid gasket (P/N 08718-0004 or 08718-0009) to the engine block mating surface of the oil pump, and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.

NOTE:
* Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A), (B), and (C).
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.

5. Apply liquid gasket (P/N 08718-0004 or 08718-0009) to the oil pan mating surface of the oil pump, and to the inside edge of the threaded bolt holes. Install the component within 5 minutes of applying the liquid gasket.

* Apply a 2.5 mm (0.098 in) diameter bead of liquid gasket along the broken line (A).
* If too much time has passed after applying the liquid gasket, remove the old liquid gasket and residue, then reapply new liquid gasket.

6. Set the edge of the oil pump (A) on the edge of the oil pan (B) with new O-rings (C).

7. Install the oil pump on the engine block (D).

8. Loosely install the dowel bolts (E), then tighten the 8mmbolts (F), the 6 mm bolts (G) and the dowel bolts.

9. Wipe off the excess liquid gasket on the oil pan and oil pump mating surface.

NOTE:
* When installing the oil pump, do not slide the bottom surface onto the oil pan mounting surface.
* Wait at least 30 minutes before filling the engine with oil.
