Nutri-Pro® Spring Plunger Update

NP40 and NP4000 Applicators

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:

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 on the lock channel, and a stroke control

valve on the cylinder, this kit is not required.

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 test-

folding 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. Move the applicator to a location with:

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.

• ﬂat, non-combustible surface free of ﬂammable

materials

• adequate illumination

• clear surface beneath for recovery of any falling or

dropped parts

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.

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.

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.

Test Installation

Test Fold

The applicator is presumed to be raised.

Refer to Figure 21

72. Swing the standard cylinder stop channels fully

open.

73. Swing each spring plunger assembly up off the

valve. Swing the channel and plunger up off the rod,

and rest it on the holder . Pin the channel handles

(not the plunger handle) in the holder.

This is the transport conﬁguration for the plunger

and cylinder stop channel.

74. Check that all hydraulic connections are made and

that connectors were torqued to speciﬁcation.

75. Hitch the applicator to a suitable tractor, including all

hydraulic connections.

76. For the fold circuit, slowly move the tractor handle to

Retract. As the wings just begin to move, set the

circuit to Neutral. Inspect for leaks

Refer to Figure 22

77. Resume circuit retraction until the wings are fully

folded. Consult the Operator manual for illustrations

of correct sequence. When the wings reach the

supports, set the circuit to Neutral. Make another

inspection for leaks.

78. Install the wing lock pins (not shown, see Operator

manual).

Move the applicator to ﬁeld conditions for the remaining

tests.

Refer to Figure 23 and Figure 24

79. Remove the wing lock pins (not shown, see

Operator manual).

80. Extend the lift-assist circuit to free the lift lock

channels.

81. At each wing, un-pin both cylinder stop channels.

82. Set the spring plunger so that the spring-loaded

bolt rests on the cylinder, inboard of the stroke

control valve.

83. Rest the standard cylinder stop channel against

the end of the cylinder.

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.

Reference Information

Connector Identiﬁcation

Refer to Figure 27 (a hypothetical ﬁtting)

Leave any protective caps in place until immediately prior

to making a connection.

Abbreviations

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 and the 37°cone 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 and elastomer O-ring .

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 and jam nut

(“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.
