Measure the entire bore of each cylinder with
cylinder bore gauge J5347 which has a dial indica-
tor calibrated in .0001 inch increments. The
standard block bore is 4.6260 inch to 4.6270
inch.

First, place the bore gauge in the master ring
gauge J8386-01 which has anI.D. of 4.6270 inch
and set the dial to zero. Next, rotate the dial
clockwise .0005 inch to give a zero dial indica-
tor setting of 4.6265 inch. Take measurements on
the cleaned-up surface only at positions A, B, C,
D, E and F in the bore on axes 45apart. Read
the measurements from the zero mark on the gauge.
The readings may be recorded on a form similar to
the on, illustrated.
