Installation

5.3 Installing the Backhoe

Place the backhoe in a flat, level area clear of other machines
and equipment. Leave the backhoe on the shipping skid.
1. Make sure there is enough room and clearance to reverse
the tractor up to the backhoe.
2. Stop close enough to the backhoe so the hydraulic lines
can reach the couplers on the tractor.
3. Attach the hydraulic hoses. Use a clean rag or paper towel
to clean any dirt from around the coupler on the hose end
and on the tractor. Connect the pressure line to a circuit that
has a detent (or on/off) control to allow for steady oil flow.
Make sure the couplers are securely seated.
IMPORTANT! Return line has a black nipple cover. Pressure
line has a red nipple cover.
NOTE: The backhoe is equipped with a directional control
valve that does not allow reverse flow if lines are
connected incorrectly.
4. Attach the backhoe mount assembly to the backhoe main
base bracket. Use the 5/8" NC bolts and nuts provided — 4
for each left- and right-hand side.
5. Use the dipper arm / stabilizer legs to tilt the bracket /
backhoe on an angle, so that the bottom attach points line
up with the hooks on the bottom of the sub-frame on the
tractor.
6. Use the backhoe hydraulics to raise the bracket assembly
into the bottom of the hooks for positive attachment.
7. Use the backhoe hydraulics to rotate the bracket assembly
into the top attach points on the sub-frame. Rotate the
bracket until it reaches the stop. The pin holes will then be
aligned.
8. Insert the two welded universal pins into the pin holes and
secure with lynch pins.
9. Install the toplink. Check that all moving parts have
clearance and do not interfere with the sub-frame.
Hydraulic oil under pressure can penetrate the
skin or eyes causing serious injury.
• Tighten all connections before applying
pressure.
• Search for leaks with a piece of cardboard
or wood, not your hand. Take care to protect
hands and body from high-pressure fl uids.
Wear a face shield or goggles for eye
protection.
• If an accident occurs, see a doctor familiar
with this type of injury immediately.

IMPORTANT! Wallenstein backhoes have been designed
to rigidly attach to the tractor or skid steer. Operating
the tractor 3-point hitch or the skid steer bucket / loader
controls should be avoided. Doing so can damage the
subframe or skid steer tieback mount.
Risk of crushing injury! Do not operate the
backhoe without toplink installed.
