1001420 HOSE KIT
General Description
These set-up instructions are for operating the
1020/1027 loader using a single-lever control
mounted on the right loader upright as shown Figure
13. To use this hydraulic connection, hose kit
1001420 must be connected between loader control
valve and tractor hydraulics.
Install control valve before proceeding.
NOTICE
■ If hydraulic lines are not connected as shown
in this manual, the control valve may be damaged.
A blocked outlet (RETURN) or improper hose con-
nection will cause pressurized oil to enter the
return circuit and damage the valve.

NOTICE
■ Removal of the accessory plate or remote
valves with a load being held on the 3-point hitch
will result in escape of high pressure oil and sud-
den, uncontrolled drop of 3-point hitch arms.
Before attempting to install this kit, the following must
be observed:
● Shut off engine, place transmission in neutral,
and apply parking brake.
● Fully lower any equipment supported by the trac-
tor remote hydraulic valves, if so equipped. Acti-
vate any remote valves to relieve all hydraulic
pressure in the remote circuits.
● Fully lower the 3-point hitch.
1. Thoroughly clean the top front of the hydraulic
accessory plate.
2. Install elbows (1) and (2) to adapter plate (3).
3. Remove accessory plate cover (A). Be careful not
to disturb the O-rings that need to stay with the
cover plate when it is removed.
4. Install O-rings to bottom of adapter plate (3). Use
petroleum jelly to keep the O-rings in the
counterbores.
5. Place the adapter plate over hydraulic opening.
6. Place the accessory plate cover onto the adapter
plate. Make sure O-rings stay in the
counterbores.
7. Secure with hex head cap screws and flat washer
as shown in Figure 14.
