and shims on inner mid section with two flat headed
screws each.
NOTE: Use shims as necessary to adjust wear pad so it is
within 0.078 in (2 mm) of the base section side
plate. Use equal number of shims on each side.
69. Position the guide block and shims as noted during
disassembly in the top inside of the base section.
Secure with the capscrews and washers. Do not tighten
bolts at this time.
NOTE: Use shims as necessary to adjust guide block so
that the guide block is within 0.118 to 0.197 in (3 to
5 mm) of the top of the inner mid section.
