Sterling D48160s manual Loosen the Mounting Screws, Remove the BED Knives

SETTINGS AND ADJUSTMENTS

SECTION 4-4

Adjusting or Replacing Bed Knives

LOOSEN THE MOUNTING SCREWS

Select either the upstroke knife or the down-stroke knife for first removal.

Loosen the bed knife screws with a 30 mm socket mounted on a breaker bar. These screws are tightened to a torque of 472 ft Ibs (640 Nm) so make sure you have the proper breaker bar (a four foot long (1.2 m) bar with a 3/4 inch (19 mm) drive is suggested). Make sure you have solid footing while you apply the breaking force.

REMOVE THE FIRST KNIFE CLAMP OR SHIELD

Remove the screws on one half of the selected bed knife using a 30 mm socket or equivalent wrench.

NOTE: When removing the knife clamp on the upstroke knife (the similar piece on the down-stroke knife is called knife shield), hold the clamp while removing the last screw to keep it from slipping off its inclined mounting surface. The knives will not slip off because they are, secured by the captive adjusting screws.

Keep the screws for reinstallation or use new factory- sup- plied screws of the same specification for replacement.

Repeat the removal procedure for the remaining knife clamps and shields.

REMOVE THE BED KNIVES

Remove the bed knives by lifting each half until the captive screws are clear of their slots.

Remove the second bed knife using the same procedure.
