Two-Outlet Hydraulic Kit
2- and 3-Section Drills
Used with drill models:
• 2S-2600/F/HD/HDF
• 3S-3000/F/HD/HDF
• 3S-4000/F/HD/HDF
• 3S-5000/F/HD/HDF
General Information
These instructions explain how to install the Two-Outlet
Hydraulic Kit. This combines the drill’s two Lift circuits
(Opener and Transport) into a single circuit at the hitch.
With this kit, a tractor having only two remotes can
operate a drill which would otherwise require three
circuits.
These instructions apply to:
Kit Kit Description
194-122A 3S TWO OUTLET TRACTOR HYD. KIT
This kit relies on some existing drill components.
This kit includes some parts not required, depending on
drill vintage, and drill options already present or also
being installed at this time.
If Markers are also to be installed, install the Two-Outlet
Hydraulic Kit first.
When you see this symbol, the subsequent instructions and
warnings are serious - follow without exception. Your life
and the lives of others depend on it!

Before You Start
Review these instructions, and make sure you
understand which existing system components are reused, and where they are located. The new components,
and the existing components to be re-used or discarded,
are located on the tongue of the drill, near the hitch.
Inventory the contents per “New Parts: Kit 194-122A”
on page 9.
Tools Required
• basic hand tools
• a tractor with two hydraulic circuits and suitable hitch
• liquid thread sealant
(for NPT fittings only - do not use PTFE tape)
• buckets for recovery of hydraulic oil from open hoses
These instructions presume a drill that has seen some
use, and may have pressure in the hydraulic system. The
installation may be done with the drill folded or unfolded.
Negative Tongue Weight Hazard:
If unfolded, the drill must be hitched to a tractor during
Opener Lift, to avoid negative tongue weight. Hitch loads can
range between +4000 pounds (folded) and -1000 pounds
(unfolded), depending on drill model and configuration.
Pre-Assembly Preparation
Inspect the Mounting Site
Refer to Figure 2
1. Examine the mounting site on the tongue. See if a
valve is already on the valve mount , and if any
hoses are under the clamps just aft of the mount.
2. Make sure the clamp hardware ( or ) is present.
It may be one of two different styles, depending on
the drill vintage. If there are no hoses under the
clamp, remove and save any: bolts, lock washers,
flat washers, clamp hold-downs, clamps and hose
guards.
If the drill does not have markers installed, a valve
mount welded on the tongue is available. The TwoOutlet selector valve mounts there, and includes a
bracket to provide a second mount point for another
valve.
If the drill already has markers installed, the valve mount
welded on the tongue already will already have a valve
mounted on it. You can mount the Two-Outlet selector
valve above it, or exchange their positions, using the
bracket in this kit.

Hydraulic Pressure Relief
High Pressure Fluid Hazard:
Only trained personnel should work on system hydraulics!
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin, causing serious injury. Avoid the hazard by
relieving pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. If an accident occurs,
see a doctor immediately. Any fluid injected into the skin must
be surgically removed within a few hours or gangrene will
result.
Installation of this kit may require, at a later step, breaking
sealed hydraulic connections at quick-disconnect
couplers. It is crucial to safety that these lines be
depressurized.
3. If the available tractor has hydraulic circuits with
“float” capability, connect the Transport and Opener
Lift circuits, and relieve any residual system pressure
by floating the circuits.
If no suitable tractor is available, “crack” (carefully
loosen) the connections for both Lift circuits the at
the bleeding points specified in the drill Operator
manual. Leave them cracked for later bleeding.
Bleed only at:
JIC (Joint Industry Conference, 37° flare) or
NPT (National Pipe Thread, tapered) fittings.
Never bleed at:
ORB (O-Ring Boss) or
QD (Quick Disconnect) fittings.

Note: Although this sequence leaves the marker/fold
selector valve on the bottom, you may prefer to
have it on top (a more intuitive location, as the
markers are above the lift cylinders). The existing
valve may be moved, or you can change the hose
connections later (the valves are identical parts).

Prepare New Hitch Hoses
Two circuits (Transport Lift and Opener Lift), which were
intended for direct connection to tractor remote ports, are
reconnected to the new selector valve starting at step 19.
Any Quick Disconnects (QDs) or hose handles on those
hoses are transferred or replaced.
The kit includes two new hitch hoses to the tractor. For
newer drills (with hose handles), continue at “2012+
Remove/Transfer Hose Handles”. For older drills
(without hose handles), continue at “2011- Remove/Add
Quick Disconnects” on page 6.

Refer to Figure 9 (depicting 2012+ hoses - 2011- hoses are
MNPT-terminated without adaptors)
Note: Do not use thread sealant on JIC or ORB
connections.
Note: It may be necessary to loosen the FNPTS-MORB
adaptors on the valve in order to tighten hose
NPT connections without twisting the hoses.
Alternatively, hoses can be disconnected at
cylinder-end JIC connections.
19. Connect the Transport Lift hoses to the forward
valve ports (stamped “1B” and “2B”).
Connect the rod (retract) hose to the upper port

Existing Parts Affected
The following existing parts may be involved in the kit
installation. Which clamp bracket and fasteners are
present depends on drill vintage.The Disposition column
indicates whether parts are left in place, moved or not reused.
The part call-out numbers in the list match all Figures in
the installation instructions. Descriptions match those in
your drill Parts manual.
On an existing drill that has seen some use, and on
which markers have never been installed, the clamp may
be missing.
Part numbers are provided for ordering replacements.
The current bracket set is at left above, based on clamp
