Bedknife Replacement and Grinding

Removal

1.Remove bedbar from frame (see Bedbar Removal).

2.Remove screws from bedbar using a socket wrench and bedknife screw tool (see Special Tools). Discard screws. Remove bedknife from the bedbar (Fig. 13).

3.Use scraper to remove all rust, scale and corrosion from bedbar surface before installing bedknife.

Replacement

1.Make sure bedbar threads are clean. Use new screws. Apply clean SAE 30 oil to the screws before installing.

IMPORTANT: Do not use an impact wrench to tight- en screws into the bedbar.

2.Using a torque wrench and bedknife screw tool, tighten screws to a torque of 200 to 250 in–lb (22 to

28Nm). Use a torquing pattern working from the center toward each end of the bedknife (Fig. 14).

3.Install bedbar to frame (see Bedbar Installation).

Grinding

Since there can be variations in the mounting surface of the bedbar, a new bedknife will not be perfectly flat after it is installed. Because of this, it is necessary to backlap or grind a new bedknife after installing it to the bedbar. Follow the existing angle that was ground into the bed- knife and grind only enough to make sure the top surface is true (Fig. 15).

1.Remove bedbar from the cutting unit (see Bedbar Removal).

Note: When grinding, be careful to not overheat the bedknife. Remove small amounts of material with each pass of the grinder.
