- From the position where the front camshafts have now been installed, rotate the generator rotor approx. 2/3 turn (234°) and align the "R I T" line А on the crankshaft with the index marks В of the upper crankcase hole.
Caution:
- Pull the cam chain upward, or the chain will be caught between crankcase and cam drive sprocket.
- To adjust the camshaft timing correctly, be sure to align "R I T" line А with the index mark В and hold this position when installing the camshafts.
- The camshafts are identified by the embossed letters.
- Before replacing the camshafts on cylinder head, apply MOLYBDENUM OIL SOLUTION to their journals and cam faces.
- Apply a MOLYBDENUM OIL SOLUTION to the camshaft journal holders.
Molybdenum oil solution
Note: Before installing the camshaft, check that the tappets are installed correctly.
- Pull the cam chain lightly.
- The intake camshaft sprocket has an arrow marked "1" С. Turn the intake camshaft so that the arrow is aligned with the gasket surface of the cylinder head.
- Engage the cam chain with the intake camshaft sprocket.
- The other arrow marked "2" D should now be pointing straight up. Starting from the roller pin that is directly above the arrow marked "2" D, count out 18 roller pins (from the intake camshaft side going towards the exhaust camshaft side).
- Engage the 18th roller pin E on the cam chain with the arrow marked "3" on the exhaust sprocket.
Note: The cam chain should now be on all three sprockets. Be careful not to move the crankshaft until the camshaft journal holders and cam chain tension adjuster are secured.
Rear cam chain tension adjuster
- The cam chain tension adjuster are identified by the embossed letters (R-UP).
- Retract the push rod by pushing the stopper 1.
- Install a new gasket 2.
Caution: Use a new gasket to prevent oil leakage.
- Install the cam chain tension adjuster 3 and tighten its mounting bolts.
Cam chain tension adjuster mounting bolt:
- 10 Nm (1.0 kgf·m, 7.0 lb·ft)
- Install the spring 4.
- Install the gasket 5 and cam chain tension adjuster cap bolt 6.
Note: Click sound is heard when the cam chain tension adjuster cap bolt is installed.
- Tighten the cam chain tension adjuster cap bolt to the specified torque.
Cam chain tension adjuster cap bolt:
- 23 Nm (2.3 kgf·m, 16.5 lb·ft)
Caution: After installing the cam chain tension adjuster, check to be sure that the adjuster works properly by checking the slack of cam chain.
