3. Install the depth stop lower bumpers (1)
through the slot in the bottom of the torque
tube depth stop weldment (2). Orientate the
lower bumpers (1) so the taper is f acing towards the front of the implement. Allow the
lower bumpers (1) to slide to the front of the
channels in the torque tube depth stop weldment (2).
4. Slide the depth stop lower bumpers (1) up and
down in their slots to check for binding. If binding occurs it will be necessary to remove the
bumper and sand or file to remove an y paint
or burrs which may limit travel in the slot.

5. Place the flat filler bars (1) on the mounting
plates for the torque tube depth stop weldment (2). Orientate the bars (1) with the holes
towards the top of the implement.
6. Place the torque tube depth stop weldment
(2) on the mounting plates trapping the flat
bars (1) in the slots where the lower bumps
were installed in step 3 above.
7. Fasten the torque tube depth stop weldment

10. Tap the bumper (1) forw ard or bac kward until
the front surface of the base plate measures
32 1/2" from the inside surface of the forw ard
cross tube of the implement frame.
11. Recheck the placement of the bumper (1)
with the weld gage (2) making sure the
bumper is straight. Make sure the clamp is
tight and then recheck measurements again.
12. Tack weld the bumper (1) to the implement
frame in sever al places . Place the w elding
ground as close to the welding area as possible, prefer ably on the bumper (1) itself. This
will assure that no arcing will take place
through any bearings or pivot points.
13. Remove the transport locks and lower the unit
down to check for clear ance and function.
NOTE: It ma y be necessary to adjust the hydraulic
stop paddle to a deep setting to allow implement
enough travel to chec k for clearance.
14. Raise implement and reinstall the transport
cylinder locks.
15. Finish welding the bumpers to the frame.
Weld along each side and across the front
and back of each bumper.
16. After the weld has cooled, repaint the surface
with the spray paint provided with the kit.

Escaping fluid under pressur e can have sufficient pr essure to penetrate the skin. Check all hydraulic lines
and fittings before applying pressure. Fluid escaping
from a very small hole can be almost in visible. Use paper or cardboard, not body parts, and wear heavy
gloves to check for suspected leaks. If injured, seek
medical assistance from a doctor that is familiar with
this type of injury. Foreign fluids in the tissue must be
surgically removed within a few hours or gangrene
will result.
