ASSEMBLY INSTRUCTIONS
3-5
Parabolic Shank Assembly
1. The spring clamp weldments are already located on
the frame at the proper spacing.
2. Attach shank assembly to lower hole of spring clamp
using 7/8-9 x 8-1/2 hex head cap screw and hex lock
nut. Tighten the nut on the hex head cap screw to
200 ft.-lbs. Grease hollow bolt
(See Figure 3-2.)
3. Assemble spring anchor plates to shank assembly
using 5/8-11 x 4 hex head cap screws and hex lock
nuts. The bottom edge of stop bracket should be just
above the wear guard clamp. Leave screws loose
until springs have been installed.
IMPORTANT
Plate with tapped hole for spring pivot bolt should be
on left side of shank. If reversed, shank will be at
improper angle!
IMPORTANT
1-8 x 8-1/2 hex head cap screw located in spring
anchor plates should be installed in opposite
direction to 1-8 x 8-1/2 hex head cap screw in spring
clamp weldment.
Install coil spring assembly between the spring clamp
weldment and the rear spring anchor plates. Secure with
1-8 x 8-1/2 hex head cap screw
and hex lock nuts.
IMPORTANT
Do not overtighten bolts as the springs must be free
to pivot.
4. Tighten 5/8-11 x 4 hex head cap screws in spring
anchor plates to correct torque.
5. Adjustment holes are provided at the top of the
spring clamp weldment to compensate for varying
ground conditions.
