a) remove blade shift bar
NOTE: Before disassembly check the clearance between
the snap ring on bushing and the shims. On the earlier
models the maximum clearance will be approximately
.014 in. (.356 mm). On the later models the maximum
clearance will be .350 in. (8.89 mm) between the snap
ring and shims.
1. Remove snap ring (2) and shims (3) from
2. Remove the bushings from lockplate (4)
toward the front of the machine with tooling (A).
3. Lower the temperature of the new bushings for
the earlier models to -70 to -900F (-57 to -
680C) on the later models lower the
temperature to -6 to -260F (-21 to -320C).
Install the bushing in the lockplate with tooling
(B). Install the bushing so it makes contact with
the shoulder in the lockplate.
4. Install the shims and the snap ring on the
bushing. The shims are used to get a .014 in.

NOTE: Some lockplate bushings can have replacements
made with the blade lift bar in position on the machine. It
will be necessary to put the blade lift bar and centershift
