Flex Disc Gang Installation
Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall onto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
IMPORTANT
1. Read all safety precautions at the front of this
section before attempting any of the following
procedures.
2. See Figure 3-9 for part names.
1. Disc gangs are partly assembled at the factory.
Some assembly is needed before installing on the
frame. A special wrench is used to tighten 1-1/2" nuts
on the disc gangs.
2. Assemble the flex mount shanks to the disc bearing
mounts using 3/4-10 x 2-1/2 hex head cap screws.
Be sure the open end of the flex shank is facing the
rear of the disc gang.
3. Insert the disc gang mounting pins into the disc gang
tubes (2 per tube). Assemble the disc gang tubes to
the flex shanks using u-bolts, mounting plates,
spacer plates, and nuts. The two shorter tubes are
for the front disc gangs. The two longer tubes are for
the rear disc gangs.

ASSEMBLY PROCEDURES
IMPORTANT
The front and rear disc gang tubes are the same
length for 4-blade disc gangs (on 2215's) and 6-blade
disc gangs (on the 2217's).
4. Set the disc gang tubes each with one right (R) and
one left (L) disc gang. Disc gangs are to be
assembled left and right as shown in Figure 3-9.
5. Find your model of the Weatherproofer in Figures
2-1 through 2-12. Study the diagram to assist you in
properly placing the disc gangs for your machine
type. Decide at this time which disc gang angle you
º
will be using (10
, 15
6. Use a hoist or forklift combination to position the disc
gangs under the front of the frame (See Figure 3-9.)
7. Carefully, lower the jackstands and release the
cylinder lockouts from the gauge wheel cylinders to
lower the machine onto the disc gangs.
8. Secure the disc gangs to the frame. Use the disc
gang pins and one each 1-1/2-12 hex nut and hex
jam nut. Set the outer pins in the proper holes to
achieve the desired disc gang angle (10
Tighten 1-1/2 nuts to 1200 ft-lbs of torque. (See
Figure 4-4 for an example of torque).
9. After disc gang installation is done, place an amber
reflective tape square on the front outer end of the
front disc gang tubes, and a red reflective tape
square on the rear outer end of the rear disc gang
tubes.
10. Insert cotter pins through the top of the disc gang
mounting pins.
11. Install scrapers per Figure 3-9 . Adjust according to
instructions in step 5 on page 4-3.
IMPORTANT
Scrapers are not used on the outside discs on front
gangs or the inside discs on rear gangs.
