Servicing the Bedknife/Bedbar Assembly
NOTE: The bedbar on each 335-D cutting unit has a
precision ground mounting surface to provide an excel-
lent fit with a bedknife. Backlapping of replacement
bedknives is often sufficient to achieve an excellent
cutting edge with minimum material removed.
Bedknife/Bedbar Removal:
1. Remove the shoulder bolts,bushings and spacers
f
rom each end of the unit and remove the bedbar/bed-
knife assembly (Fig. 16).
2. Remove the mounting screws for the bedknife and
sep
arate the bedknife from the bar (Fig. 17). Discard the
screws.
Assembly:
1. Thoroughly clean the bedknife mounting face on the
be
dbar of all rust and scale. Remove any material on
the mounting face of the bedbar that will affect a good
match-up with the bedknife.
2. Before installation, apply a coating of “Never Seez”,
or
any material that will ease future disassembly of the
bedknife mounting screws, to the threads before instal-
lation.
3. Use a torque wrench and special bedknife screw tool
to c
omplete tightening of the screws (Fig. 18). Tighten
the screws to a torque of 250 in.-lb (28 Kgm) beginning
with the center screw and tightening alternate screws
toward each end to insure the bedknife will be flat
against the bedbar.
4. Install the bedbar/bedknife assembly to the cutting
un
it.
