FIGURES 2-1 THROUGH 2-5 FOR SHANK
SPACING.
3-4.2 Always install the center shank first.
Install it at the center of the frame assembly
on the correct mounting tube. All other
shanks are evenly spaced relative to the
center shank, using 24" or 30" spacing (not
both). Install the outermost shanks last.
3-4.3 Assemble the spring clamp weldment to
the frame bars using the clamp u-bolts, dou-
bler clamp, and 7/8-9 hex lock nuts, as fol-
lows:
a. Install the spring clamp weldment and the
u-bolts.
b. Tighten the u-bolt until the front of the u-
bolts are tight against the frame.
3-4.4 Install spikes on shanks using a 3/8 x 2
spring slot pin. If installing wearguards, seat
spike on shank. Then install wearguard into
slot and clamp in place with wearguard
clamp without unseating spike.
CAUTION
IMPROPERLY SEATED SPIKES MAY
SHEAR OFF ROLL PIN, CAUSING
LOSS OF SPIKE AND WEARSHIN.
3-4.5 Attach the shanks to the spring clamp
weldment with 7/8-9 x 8-1/2 hex head cap
screw, bushing, hollow bolt, 1-1/2 -12 hex
nut, 1-1/2 -12 jam nut, and 7/8-9 hex lock
nut. Tighten the nut on the cap screw to 200
ft.-lbs. Grease hollow bolt.

wear guard stop bracket to shanks using
3/4-10 x 4 hex head cap screws and hex
lock nuts (leave bolts loose until springs
have been installed). The bottom edge of
wear guard stop bracket should be just
above the wearguard clamp.
IMPORTANT
PLATE WITH TAPPED HOLE FOR SPRING
PIVOT BOLT SHOULD BE ON LEFT SIDE OF
SHANK. (IF REVERSED, SHANK WILL BE AT
IMPROPER ANGLE!)
