Measuring Gear Lash (0-53)
Position an indicator on a tooth of the camshaft gear.
NOTE: The cylinder block position shown in the illustration
is for clarity. The cylinder block must be positioned with the
crankshaft on top to keep the tappets in the bores.
Note the camshaft gear backlash. Mark the camshaft
gear and crankshaft gear for further analysis if backlash
exceeds limits.

NOTE: Prevent movement of adjoining gear when checking
backlash or the reading will be the total of both gears.
Rotate the crankshaft to approximately the TDC position
for number one cylinder. Failure to do so will result in the
camshaft catching on the connecting rods during cam-
shaft removal.
NOTE: The cylinder block is shown in an upright position in
the illustration for clarity.
