Do Not Over Tighten Nuts!
Replacing Worn or Damaged Discs
These instructions are for replacing worn or
damaged discs of the drum section.
Preparations:
1. Remove drum section from frame.
2. Determine the shortest point to
worn/damaged disc.
3. Remove pillow block bearings from the
axle on the end you are working with by
loosening the set screw.
NOTE: It might be difficult to remove the
bearings because of the beveled edge created
by the set screws.
Removing discs:
1. Remove nylon lock nuts and washers from
tie rods.
NOTE: WITTEK uses nylon lock nuts on all nuts
and bolts combinations. It is recommended
that when replacing the lock nut, a new nylon
lock nut is used. Nylon lock nuts can be
purchased at any hardware store (standard size
of 3/8” is used).
Reassembling discs:
1. Replace disc(s) that were removed.
2. Replace the spacer, wheel only, tire and
wheel only.
NOTE: Before replacing the end plate and
pillow block bearings, lightly sand the shaft to
smooth out beveled edges or other nicks
created by the set screw (this will make it
easier to replace the end plate and pillow
block bearings).
3. Replace end plate.
4. Replace washers and nuts on tie rods.
5. Finger tighten all nuts evenly.
6. Place drum section on a flat surface
(i.e. worktable).
7. Using a golf ball as a guide tool, insert the
golf ball in the space between each disc to
determine that the golf ball fits “snugly”
and that the golf ball does not slide down.
If sliding occurs, retighten the nuts on the
tie rods until you have reached the
desired snugness in each disc section.
8. Replace nut and bolt on end plate.
9. Replace pillow block bearings.
DO NOT TIGHTEN SET SCREW on the pillow
block bearing.
10. Loosen the set screw on the
pillow block bearing on the other end of
drum section.
11. Replace drum onto frame of picker.
12. Align the drum section by centering the
fingers on the frame in each disc section.
13. TIGHTEN set screws on the pillow block
bearings on both ends of drum section.
