    1. Put the rocker shaft holders, the camshaft, the camshaft holders, and cam chain guide B on the cylinder head, then tighten the bolts, in sequence, to the specified torque.

    2. Seat the camshaft by pushing it away from the camshaft pulley end of the cylinder head.
    Specified Torque: 
    15 Nm (1.5 kgf-m, 11 lbf.ft/lbf.in) 

    3. Zero the dial indicator against the end of the camshaft, then push the camshaft back and forth, and read the end play. If the end play is beyond the service limit, replace the cylinder head and recheck. If it is still beyond the service limit, replace the camshaft.

    Camshaft End Play 
    Intake: 
    Standard (New):  0.05-0.25 mm (0.0020-0.0098 in)
    Service Limit:  0.40 mm (0.0157 in) 
    Exhaust: 
    Standard (New):  0.05-0.25 mm (0.0020-0.0098 in)
    Service Limit:  0.40 mm (0.0157 in)

    4. Loosen the camshaft holder bolts two turns at a time, in a crisscross pattern. Then remove the camshaft holders from the cylinder head.

    5. Lift the camshafts out of the cylinder head, and wipe them clean, then inspect the lift ramps. Replace the camshaft if any lobes are pitted, scored, or excessively worn.

    6. Clean the camshaft journal surfaces in the cylinder head, then set the camshafts back in place. Place a plastigage strip across each journal.

    7. Install the camshaft holders, then tighten the bolts to the specified torque as shown in step 1.

    8. Remove the camshaft holders. Measure the widest portion of plastigage on each journal:

    • If the camshaft-to-holder clearance is within the service limits, go to step 10.
    • If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has been replaced, replace the cylinder head.
    • If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has not been replaced, go to step 9.
    Camshaft-to-Holder Oil Clearance 
    Standard (New): 
    No. 1 Journal:  0.030-0.069 mm (0.00118-0.00272 in)
    No. 2, No. 3, No. 4, No. 5, and No. 6 Journals:  0.060-0.099 mm (0.00236-0.00390 in)
    Service Limit:  0.150 mm (0.00591 in)

    		 9. Check the total runout with the camshaft supported on V-blocks:
    • If the total runout of the camshaft is within the standard, replace the cylinder head.
    • If the total runout is beyond the standard, replace the camshaft and recheck the camshaft-to-holder oil clearance. If the oil clearance is still beyond the standard, replace the cylinder head.
    Camshaft Total Runout 
    Standard (New):  0.03 mm (0.0012 in) max.

    		 10. Measure cam lobe height.

    Cam Lobe Height Standard (New): 
    PRI: Primary MID: Mid SEC: Secondary
    C/C: Cam Chain  
      INTAKE EXHAUST
    PRI 35.555 mm (1.39980 in) 35.095 mm (1.38169 in)
    MID 35.874 mm (1.41236 in)
    SEC 35.555 mm (1.39980 in)
  6. All Removed Parts - Install
