Installation Instructions 1
Grease Bank Kit
7- and 10-Foot EWNT Drills
Used with:
• 705 (all models)
• 1005 (all models)
General Information
These instructions explain how to install a Grease Bank
Kit. These kits greatly improve the ease of lubricating
coulter pivots by adding one or two bulkheads, with zerks
and tubing to new grease adaptors at the coulters.
These instructions apply to an installation of either:
Kit Kit Description
151-126A 7’ GREASE BANK KIT
151-127A 10’ GREASE BANK KIT
Each kit upgrades an entire drill. There will be a few parts
left over if your drill has less than the maximum possible
number of coulters.
Due to shipping regulations, the kit does not include any
touch-up paint to restore the welded areas. Your Great
Plains dealer can provide it as Great Plains part:
821-001C PAINT GP GREEN SPRAY CAN
The grease bank does not serve the coulter disk bearing
zerks (if present), as they rotate and cannot accept a fixed
lubrication tube.
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, with the following objectives at
each step:
• Safety: welding is required and represents a
potential fire and personal injury hazard - plan the
location and the work to minimize risks.
• Inventory: examine any called-for items and make
sure all parts are present.
• Comprehension: make sure you understand
where each part or assembly is installed, and
what tools are required for the task.
Pre-Assembly Preparation
Work Location
1. Move the drill to a location with:
• a non-flammable surface beneath,
• adequate illumination,
• protection from weather (for painting), and;
• access to power for any power tools.
Great Plains Mfg., Inc.
!
CAUTION
There will be sparks from welding. Dry grass, wood floors, or
areas with spills of flammable fluids are not suitable locations
for the work.
Prepare Drill
2. Raise the drill and install transport locks. The work
may be performed with the drill lowered, but access
to the coulter zerks is easier when raised.
3. Block the tires and install the parking jack.
4. Disconnect all hydraulic and electrical connections at
the hitch. Secure hoses and cables to prevent
ground contact.
5. Unhitch the tractor and move it away from any potential contact with the drill frame (to prevent possible
system damage if electric welding is used).

7. Loosely assemble two mount plates inside the
ends of the mount , with the weld ears facing
away from the mount.
8. Position the assembly anywhere along the top from
edge of the drill’s mainframe tool bar. Make sure the
lower rear edge ( , the weld region) is in continuous
contact with the tool bar, and tighten the nuts to
about half of final torque (the bulkhead is disassembled and re-assembled in later steps).

Determine Mounting Location
The ideal location for the bulkhead(s) depends on drill
configuration, particularly frame-mounted coulters.
Choose locations that provide full access to the zerk
openings for maintenance, and ample clearance both
mount brackets for welding.
Refer to Figure 3
The suggested location for the single 705, and right 1005
bulkhead is toward the right end of the tool bar, near or in
front of the right arm pivot plate .
On the 1005, the second bulkhead is located at the left
end of the tool bar, near or in front of the left arm pivot

9. Using a bulkhead assembly as a guide, mark the
outline of each plate at the weld location.

Install Zerks on Bulkhead
Refer to Figure 6
Note: The fitting connector has three parts:
1
the NPT and compression body,
2
an internal ferrule, and;
3
a cap (or jam nut).
When assembling to the zerk , tighten only the
NPT body. Do not tighten the cap until tube insertion in a later step. If you remove the cap, be sure
to capture and save the ferrule.
22. Starting at the inside end of the bottom row of holes,
insert the 1/8MNPT threaded end of a zerk
through the front of the bulkhead, and secure with
the 1/8FNPT body of a fitting connector .
Torque to 1-2 turns past finger tight.
23. If the ferrule and cap were left on the connector,
make sure the cap is finger tight to prevent loss.

The tubing from the grease bank to the coulters is supplied as a single coil, and must be cut-to-length for each
bulkhead-to-adaptor run. Expect some amount of tubing
to be left over, even with a maximum number of coulters.
Pre-Position Ties
29. Starting about 5in (13cm) from the right end of the
tool bar, lay a cable tie at regular intervals along the
top of the tool bar.
For the model 705, this is about every
1

around the bar, and insert the tip into the clasp a
short distance (do not tighten the ties at this time).

Route, Cut and Terminate Tubing
For the model 1005, start with the center coulter (odd row
count) or the coulter just right of center (even row count).
For each coulter:
31. Route an end of the uncut tubing from the bulkhead to the coulter.
If there is an unoccupied hole in the mount, routing the tubing through it may be helpful.
Route into the nearest tie loop in the direction of the
coulter, then along the tool bar through ties up to the
coulter mount, and then down to the coulter.
32. Leave enough slack in the tubing for later tightening
of the ties, and avoiding sharp bends (which may
kink). Avoid excess slack and sags.
33. Cut the tubing at the bulkhead and remove it from
22
any hole used for routing.
34. Remove cap and ferrule from the adaptor .
2 3 4
35. Slide the non-threaded end of the cap and then
the large end of the ferrule onto the tubing .
36. Press the tubing end fully into the adaptor body .
37. Secure the tubing with the cap .
38. At the coulter end, press the tubing end fully into the
grease adaptor.

Secure Tubing
39. When all the coulters have had tubing routed and
attached, begin drawing up the cable ties in stages.
Leave slack for gentle bends at the back of each
grease bank.
Make sure tubing is flat against the tool bar.
Leave slack for gentle bends down to coulters, and
slack for possible future coulter height adjustments.
Closeout
40. At each bank zerk, pump until only grease (and no
air) emerges at the coulter pivot.
There should be minimal resistance until grease
reaches the coulter, and then only modest resistance.
Installation Instructions 7
If there is strong resistance, check for defective zerk,
fitting blockage, tubing blockage and grease pump
malfunction.
If resistance suddenly drops, check for tubing leaks
or disconnections.
Maintenance
