Before You Start
Parts and Tools Required
• You need a suitable tractor for positioning the planter,
and having sufficient hydraulic circuits, with adequate
capacity to operate the markers (installing markers
increases the required circuits by one).
• You need a hoist with 136 kg (300 pound) capacity.
• Have safety goggles and gloves for inspecting
hydraulic connections and handling sharp marker
discs.
• Other than the hoist, only basic hand tools are
required.
• 5 liters (1.2 gallons) of hydraulic fluid is needed to
charge the marker system.
• General purpose grease lubricant and grease gun.
• Liquid PTFE pipe sealant, if the kit includes QD
couplers. See page 20 for more information.

Compatibility
Refer to Figure 2 (consult planter Operator manual for serial
number plate location)
1. Check the model number of the planter against the
table at right to ensure you have the correct kit.
Sequence
If installing the markers as part of export pre-delivery,
perform the installation at the point called for in the
pre-delivery manual:
401-754Q YP625/925 Export Pre-Delivery Manual
Comprehension
2. Review these instructions. Make sure the installers
understand where each part or assembly is
installed, and what tools are required for the task.

Pre-Assembly Preparation
Work Location
3. Move the planter to a location with:
• access to tractor or hydraulic power;
• adequate illumination; and,
• clear surface beneath for recovery of any falling
or dropped parts - if the surface is not clear, have
a tarp or drop cloth available.
4. Raise planter. Install lift cylinder locks and/or
parking stands, as provided. Lower planter onto
locks. This minimizes planter movement during
exercising of markers on a planter with a shared lift/
marker circuit.
5. Set all hydraulic remote circuits to Float (to ensure
that pressure is relieved). Shut off tractor or
hydraulic source.
High Pressure Fluid Hazard:
Ensure lift circuit pressure is zero at step 5. Wear gloves and
safety eyewear when working on hydraulics. Some planter
configurations require disconnecting hydraulic fittings in the
lift circuit. Dangerous releases of hydraulic fluid may occur if
pressure remains in the circuit. This could lead to serious
personal injury. If hydraulic fluid penetrates the skin, seek
immediate medical attention from a physician familiar with
this type of injury.

810-197C VALVE,SEQUENCE SHOEMAKER
Examine the valve body to establish which faces are
front, rear and bottom.
The front (supply/return) face has two FORB ports
adapted to9⁄16MJIC. They are stamped “1” and “2”.
The rear (cylinder) face has four MORB ports
adapted to9⁄16MJIC. They are stamped “C1”, “C2”,
“R1” and “R2”. The “C” ports connect to cylinder rod
(retract) ends. The “R” ports connect to cylinder
base (extend) ends.
The bottom face has two3⁄8-16 threaded holes for
mounting (not shown).

Identify Mount Style
There are two styles of sequence valve mount:
• North American Models YP425/625/825 use a ground
drive mount, based on bundle:
113-841S SEQUENCE VALVE MOUNT ASSY
This style mounts to the ground drive weldment using
existing planter fasteners and the smaller 7 mm
148
holes in the side of the mount .
• Export Models YP625PD/TD and YP925 use a fan
mast mount based on bundle:
113-867S SEQUENCE VALVE MOUNT ASY FAN
This style mounts to the existing fan post using a new
U-bolt ( , not shown) through the large 11 mm
holes in the side of the mount .

9. Align the smaller 7 mm mounting holes of the
sequence valve mount with the speed sensor
mounting holes in the ground drive weldment.
Loosely secure with saved lock washers and
15
nuts .
10. Adjust the speed sensor for a 1.6 mm gap
between its top face and the toothed wheel . See

Note: Supply hoses are FJIC-to-FJIC where the markers
are on the lift circuit (North America pull-type
planters only). One FJIC end is connected into the
existing lift circuit.
In a shared 2-cylinder circuit (Model YP425
pull-type only), the marker kit includes tees, which
replace existing elbows.
In a shared 4-cylinder circuit, the marker kit
includes a cross, which replaces existing tees.
Note: Supply hoses are FJIC-to-MNPT where the
markers are on a dedicated hydraulic circuit. The
MNPT end of the hose is connected to a QD
coupler.
Note: A hose clamp and label (see step 17) are provided
in all kits. Their use on hoses shorter than 80 cm
is optional, and is not documented in this manual.
Dedicated Supply Circuit Hose
If the supply hoses rely on a shared circuit, continue at
“Two-Cylinder Shared Supply Circuit” on page 8 or
“Four-Cylinder Shared Supply Circuit” on page 9.
13. Select the two supply hoses . See the table on
page 6 for the correct part number for the planter.
Refer to Figure 7
14. Select two new:
82
811-856C CP 1/2FNPT MALE QD
and a quantity of PTFEa pipe thread sealant.
15. Apply sealant to the MNPT threads of the hose
fittings. Attach the couplers to the MNPT ends of
the supply hoses .
