(f) Visually inspect the seating pattern in the push rod socket for excessive wear.
(15) Remove the bushing in the cam follower if the inside diameter of the bushing is more than 0.752
inch (19.10 mm).
(a) Use the lever bushing block and mandrel to remove the bushing.
(b) Use compressed air to clean the oil passage.
(c) Use the bushing block and mandrel to install a new bushing in the lever. Make sure the oil
hole in the bushing is aligned with the oil hole in the lever.
(d) Cut a chamfer on each end of the bushing. Use a drill press at a slow speed and a chamfer
tool that cuts a 60 degree angle chamfer.
(e) Put soap into the oil hole in the bushing. This will prevent metal particles from entering the
oil hole.
(f) Cut the bore in the bushing to measure 0.7501 to 0.7511 inch (19.053 to 19.078 mm).
(g) Use the plug gauge to check the bore.
(h) Use compressed air to remove the soap from the oil holes. Wash the lever in cleaning
solvent and dry with compressed air.
(i) If the socket insert in the lever was removed, use a press to install the new insert. Make sure
the insert is installed tightly.
CAUTION
If a new cam follower insert is installed in the lever, a
new push rod must also be used.
