ASSEMBLY
(Refer to Figures 14 & 15)
IMPORTANT: Tighten all hardware to the torque
requirements specified in the torque chart.
To prevent bodily injury, do not operate backhoe
unless Link Weldments (Figure 15 - Items 1 & 2)
are properly installed and adjusted. Failure to do
so may result in backhoe being thrust upward,
crushing operator against cab or ROPS.
1. Use hoist to raise the backhoe mainframe so that
the boom pivot pin is aproximately 13” off the
ground.
2. Back tractor close to the backhoe. Connect tractor
lower link arms to lower link mounts at position “C”,
Figure 14, using two L-pins (3), two cotter pins (4), and
two wire form cotter pins (5) as shown in Figure 15.
NOTE: If tractor has a Category II hitch, install two
bushings (6) in lower link arms as shown in Figure 15.
3. Attach upper braces (7), Figure 15, to backhoe with
3/4 x 7-1/2 bolt (8), flat washers (9), lockwasher (10)
and nut (11). Do not tighten hardware at this time.
4. Install bushing (12) or bushing (13) that most close-
ly matches the diameter of the tractor upper link pin in
the hole of the upper bar (14), as shown in Figure 15.
No bushing is necessary for Category II tractors.
5. Secure upper bar (14) between upper braces (7)
using 3/4 x 4-1/2 bolt (15), flat washers (9), lock-
washer (10) and nut (11). Use hoist to raise or lower
backhoe slightly until a hole in the upper bar aligns
with a hole in the upper braces. See Figure 14.
6. Attach RH lower link weldment (1) and LH lower
link weldment (2) to backhoe mainframe using 7/8 x
2-1/2 bolt (16), flat washers (17), lockwasher (18),
and nut (19). See Figure 15.
7. Align RH and LH link weldment (1, 2) with a hole in
the upper bar/brace assembly, as close to the tractor
as possible. Use 3/4 x 6 bolt (20), flat washers (9),
lockwasher (10), and nut (11). See Figure 15. You may
need to return to Step 6 and reajust the bolt connection
upward or downward .
8. Remove backhoe from the tractor.
9. Install connector bar (21) to RH and LH lower link
weldments (1, 2) using 1/2 x 1-1/2 bolt (22), lockwash-
er (23), and nut (24). See Figure 15.
10. Tighten all hardware at this time. Check your instal-
lation very carefully to be sure all members are correct-
ly installed and securely fastened.
11. If using optional PTO Pump Kit, proceed to that
section prior to mounting the backhoe onto the tractor.
12. Connect hoses from the backhoe control valve to
the tractor hydraulic system as described in Hydraulic
Hook-Up section, prior to mounting the backhoe onto
the tractor.
