ASSEMBLY (Refer to Figure 21 & 22)
IMPORTANT: Tighten all hardware to the torque
requirements specified in the torque chart.
1. Use hoist to raise the backhoe mainframe so that
the boom pivot pin is approximately 16” off the
ground.
2. Back tractor close to the backhoe. Connect tractor
lower link arms to lower link mounts at position “C”,
Figure 22, using two L-pins (214), two cotter pins (211),
and two wire form cotter pins (212) as shown in Figure 21.
NOTE: If tractor has a category II hitch, install two bush-
ings (215) in lower link arms as shoen in Figure 21.
3. Attach upper braces (221), Figure 21 to backhoe with
3/4 x 7-1/2” bolt (205), lockwasher (209), flat washers
(210) and nut (207). Do not tighten hardware at this time.
4. Install bushing (213) or bushing (216) in the hole of the
upper bar (220) that most closely matches the diameter
of the tractor upper link pin, as shown in Figure 21. No
bushing is necessary for Category II tractors.
WARNING
TO PREVENT BODILY INJURY, DO NOT
OPERATE BACKHOE UNLESS LOWER
LINK WELDMENTS (217,218) ARE PROPER-
LY INSTEALLED AND ADJUSTED. FAILURE
TO DO SO MAY RESULT IN BACKHOE
BEING THRUST UPWARD, CRUSHING
OPERATOR AGAINST CAB OR ROPS.
5. Secure upper bar (220) between upper braces
(221) using 3/4 x 5” bolts (203), flat washers (210),
and nuts (207). Use hoist to raise or lower backhoe
slightly until a hole in the upperr bar aligns with a
hole in the upper braces. See Figure 21.
6. Attach RH lower link weldment (217) and LH
lower link weldment (218) to backhoe mainframe
using 3/4 x 2-1/2” bolt (202), flat washer (210), and
nut (207). See Figure 21.
7. Align RH and LH link weldment (217, 218) with a
hole in the upper bar/brace assembly, as close to
the tractor as possible. Use 3/4 x 6-1/2” bolt (204),
flat washer (210), and nut (207). See Figure 21. You
may need to return to Step 6 and readjust upward or
downward the bolt connection.
8. Remove backhoe from the tractor.
9. Install connector plate (219) to RH and LH lower
link weldments (217, 218) using 5/8 x 2” bolt (200),
lockwasher (208), and nut (206). See Figure 21.
10. Tighten all hardware at this time. Check your
installation very carefully to be sure all members are
correctly installed and securely fastened.
10A. If using optional PTO Pump and Reservoir Kit
proceed to that section prior to remounting the back-
hoe onto the tractor.
11. Connect hoses from the backhoe control valve
to the tractor hydraulic system as described in
“Hydraulic Hook-Up” section, pages 25-27, prior to
remounting the backhoe onto the tractor.
