NoRMAl DISKING
1. Place bracket (72980B) under plate on the
outside bearing standard and secure with
1/2-13 x 1 1/2 capscrews (9390-101) and
locknuts (9800).
2. Remove the locknut (9802) from the 3/4-10
x 4 1/2 capscrew (9390-154) on the inner
bearing standard. Mount scraper bar (72981B)
to the inner bearing standard and secure with
the previously removed 3/4-10 locknut (9802)
and 1/2-13 x 1 1/2 capscrew (9390-101),
flat washer (9405-088), and locknut (9800).
If blade cover kits are installed, replace
capscrew 3/4-10 x 4 1/2 (9390-154) with
capscrew 3/4-10 x 5 1/2 (9390-156) located
in the scraper kit.
3. Mount the angle (72977B or 72978B) with
the solid leg pointing downward for the
underside of the scraper bars (72981B &
72980B). Secure with 1/2-13 x 1 1/2 cap-
screws (9390-101), flat washers (9405-088),
and locknuts (9800).
4. Mount scrapers (806140B) to the angle
(72977B or 72978B). Secure with 1/2-13UNC
x 1 3/4 carriage bolts (9388-105), flat wash
-
ers (9405-088), lock washer (9404-025) and
hex nut (9394-010).
5. For the rear gangs, remove the locknut
(9802) from the 3/4-10 x 4 1/2 capscrew
(9390-154) on the inner bearing standard.
Mount scraper bar (72979B) to the inner
bearing standard and secure with the pre-
viously removed 3/4-10 locknut (9802) and
1/2-13 x 1 1/2 capscrew (9390-101), flat
washer (9405-088), and locknut (9800).
6. Place bracket (72980B) under plate on
inside bearing standard and secure with
1/2-13 x 1 1/2 capscrews (9390-101) and
locknuts (9800).
7. Mount angle (72977B or 72978B) with the
solid leg pointing downward of the underside
of the scraper bars (72980B and 72979B).
Secure with 1/2-13 x 1 1/2 capscrews
(9390-101), flat washers (9405-088) and
locknuts (9800).
8. Mount scrapers (806140B) to the angle
(72977B or 72978B). Secure with 1/2-
13UNC x 1 3/4 carriage bolts (9388-105),
flat washers (9405-088), lock washer (9404-
025) and hex nut (9394-010).
9. Tighten all hardware. In most cases, the
scraper should NOT directly contact the
disk blade. Adjust the scraper to allow
1/16 to 1/8" clearance to the blade. Rotate
the gang to verify clearance all the way
around. As the scraper wears, it will be
necessary re-adjust. In extremely wet or
sticky soils, it may be necessary to have
the scraper contact the blade. Adjust the
scraper to maintain a light pressure on the
blade. DO NOT permit the scraper to cut
a groove in the blade or get caught in the
notches of the blade. Be sure the scraper
does not interfere with the normal rotation
of the blade. DO NOT adjust scraper to
contact blade unless absoletely necessary
as it will result in shorter scraper life.
