#### CHECKING CAMSHAFT RUN-OUT

Camshaft run-out should be checked when the camshaft has been removed from the cylinder head. An accurate dial indicator is needed for this procedure; engine specialists and most machine shops have this equipment. If you have access to a dial indicator, or can take your cam to someone who does, measure cam bearing journal run-out. The maximum (limit) run-out on the CA20E, CA18ET and KA24E camshafts is 0.02mm. The run-out limit on the Z20 and Z22 series camshafts is 0.20mm. The maximum (limit) run-out on the VG30E camshaft is 0.01mm. If the run-out exceeds the limit replace the camshaft.
