(2) Set the camshaft bearing cap with the camshaft bearing to the
cylinder head and tighten them with the specified torque.
(3) Use the cylinder gauge to measure the inner diameter of the cam-
shaft bearing.
(4) Calculate the difference between the camshaft journal outer diam-
eter and the camshaft bearing inner diameter. If the value
exceeds the standard value, replace the camshaft or camshaft
bearing.
3. INSPECTING THE CAMSHAFT RUNOUT
(1) Place the journals at the both ends of the camshaft on the V-
block.
(2) Place the dial gauge on the journals of the camshaft to measure
the runout of the camshaft. If the value exceeds the permissible
limit, replace the camshaft.
4. INSPECTING THE CAMSHAFT END PLAY
(1) Use the dial gauge to measure end play of the camshaft.

5. INSPECTING FOR BACKLASH BETWEEN THE CAMSHAFT
DRIVE GEAR AND CAM IDLE GEAR
(1) Use the dial gauge to measure the backlash between the cam-
shaft drive gear and cam idle gear.

CAM IDLE GEAR, OVERHAUL, INSPECTING THE COMPO-
NENTS (Page 10-73)
6. INSPECTING CAMSHAFT DRIVE GEAR MOUNTING BOLT
(1) Use the vernier calipers to measure an under head length of a
camshaft drive gear mounting bolt. If a measurement reading
exceeds the permissible limit, replace the bolt.
