Camshaft: Testing and Inspection
Inspection
NOTE: Do not rotate the camshaft during inspection.
1. Remove the rocker arm assembly, and disassemble it.
2. Put the rocker shaft holders, camshaft, and camshaft holders on the cylinder head, then tighten the bolts to the specified torque.
Specified torque:
8 mm bolts: 22 Nm (2.2 kgf-cm, 16 ft. lbs.)
6 mm bolts: 12 Nm (1.2 kgf-cm, 8.7 ft. lbs.)
6 mm bolts: (21), (22), (23)
3. Seat the camshaft by pushing it away from the camshaft pulley end of the cylinder head.
4. 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 camshaft head and recheck. If it is still beyond the service limit, replace the cylinder.
Camshaft End Play:
Standard (New): 0.05 - 0.20 mm (0.002 - 0.008 inch)
Service Limit: 0.4 mm (0.02 inch)
5. Unscrew the camshaft holder bolts two turns at a time, in a crisscross pattern. Then remove the camshaft holders from the cylinder head.
6. Lift the camshafts out of the cylinder head, wipe them clean, then inspect the lift ramps. Replace the camshaft if any lobes are pitted, scored, or
excessively worn.
7. Clean the camshaft journal surfaces in the cylinder head, then set the camshafts back in place. Place a plastigage strip across each journal.
8. Install the camshaft holders, then tighten the bolts to the specified torque as shown in step 2.
