Nutri-Pro® Spring Plunger Update
NP40 and NP4000 Applicators
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!
General Information
These instructions explain how to update the fold locks
on 2-point (semi-mounted) 5-section Nutri-Pro®
applicators. The kit reduces machine damage risk by
adding a hydraulic limiter for the inner fold cylinders, and
by providing lock channel capture during transport.
One kit updates one applicator.

These instructions apply to an installation of:

Kit Description
NP4000 UPDATE KIT. SPRG PLG
Refer to Figure 1
This kit is not required for pull-type applicators, or any
applicators manufactured in 2012 or later. If the
applicator in question already has the spring plunger
assembly 1 on the lock channel, and a stroke control
valve on the cylinder, this kit is not required.
Figure 1
Spring Plunger Components
Some applicators, which do require the spring plunger
update, may not require all of the parts in this kit.

Pre-Assembly Preparation
Tools Required
• suitable tractor for raising and unfolding and testfolding applicator
• clean buckets for draining hydraulic fluid
• light/white tape and marker for identifying hoses
• basic hand tools
• (most cases) wire or rod welder, tarps and fire
extinguisher; two or more 7 inch (18 cm) clamps
• (most cases) portable cut-off saw or torch (and fire
extinguisher), grinder and sanding equipment
• (most cases) Great Plains 821-001C spray paint, or
green exterior enamel close to Pantone 356C,
DuPont 262 or PPG 43817
Work Location
1.
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use
paper or cardboard, NOT BODY PARTS, to check for leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. Escaping fluid under pressure
can have sufficient pressure to penetrate the skin causing
serious injury. If an accident occurs, seek immediate medical
assistance from a physician familiar with this type of injury.
Only trained personnel should work on system hydraulics
Anhydrous Models - Suffocation, Blinding, Burning,
Freezing, Disabling and Disfigurement Hazards:
Do not perform maintenance with anhydrous ammonia in the
system. Fully discharge the system of NH3 liquid and vapor
before working on the implement.
Move the applicator to a location with:
• flat, non-combustible surface free of flammable
materials
• adequate illumination
• clear surface beneath for recovery of any falling or
dropped parts
Crushing Hazard:
When disconnecting hoses at cylinders, do not disturb
restrictor orifice plates. These plates reduce wing falling rate
in the event of catastrophic hydraulic failure. Omitting a plate
could result in serious injury or death beneath a falling wing.
Prepare Applicator
2.
If the applicator is an anhydrous model, perform a
system discharge before commencing work. This is
particularly important if the update is done indoors.
Fire Hazard:
This update may require welding and/or cutting thick metal.
Sparks are likely. Perform the work clear of flammable
materials. Wear suitable protective equipment. Allow hot parts
to cool before continuing work.
Crushing and Sharp Object Hazards:
Be careful working near row units. Knives and discs may be
sharp.
Equipment Damage Risk:
Disconnect harnesses and ground frame before welding.
Connected harnesses or ungrounded frame during welding
can result in permanent damage to electronic components.

against
84. Extend the fold circuit to unfold the wings.
The channel and spring plunger fall into place,
causing the inner wing unfold to stop just above
wings-level, followed by outer wing unfold.
85. Set the fold circuit to Neutral. Inspect the inner wing
elevation, and the engagement of the spring-loaded
bolt with the stroke control valve actuator.
If the inner wings stopped at or below wings-level,
raise the wings slightly and make adjustments to the
spring plunger assembly.
Note: The spring plunger is used only for initial unfold
from transport configuration. It is disengaged for
field operations. See the updated Operator
manual for details of field operations.

Refer to Figure 27 (a hypothetical fitting)
Leave any protective caps in place until immediately prior
to making a connection.

NPT - National Pipe Thread
Note tapered threads, no cone/flare, and no O-ring.
Apply liquid pipe sealant for hydraulic applications
(do not use tape sealant, which can foul filters).
JIC - Joint Industry Conference (SAE J514)
Note straight threads 4 and the 37° cone 5 on
“M” fittings (or 37° flare on “F” fittings). Use no
sealants (tape or liquid) on JIC fittings.

Over-Torque Leak Risk:
JIC (Joint Industry Conference 37° Flare) fittings do not
require high torque. Excess torque causes leaks. JIC
fittings do not require sealant.
ORB - O-ring Boss (SAE J514)
Note straight threads 5 and elastomer O-ring 7 .
Prior to installation, to prevent abrasion during
tightening, lubricate O-ring with clean hydraulic fluid.
Use no sealants (tape or liquid) on JIC fittings.
ORB fittings that need orientation, such as the ell
depicted, also have a washer 8 and jam nut 9
(“adjustable thread port stud”). Back jam nut away
from washer. Thread fitting into receptacle until
O-ring contacts seat. Unscrew fitting to desired
orientation. Tighten jam nut to torque specification.

High Pressure Fluid and Equipment Damage Hazards:
Bleed only at JIC and NPT fittings.
Never try to bleed a QD (Quick Disconnect) fitting.
Avoid bleeding at ORB fittings. The O-ring is likely to be torn
if any pressure remains in the circuit.
