***Installation Guide – Case IH Series Hydraulic Compressor
STEP 1: RESIDUE MANAGER (RM) OR RM/COULTER COMBO INSTALLATION
Residue Manager Only: Install RM Assemblies securing with mounting hardware. Install the wheel mount assembly on the adjustment tube
th
th
so the top hole of the wheel mount aligns to the 4
or 5
hole down from the top of the adjustment tube for conventional tillage/mellow soils,
th
th
5
or 6
hole from the top for no till/minimum till conditions. Install wheels on wheel mounts using hardware from the 2966-119 bolt bag.
Install the RM wheels so that the left wheel leads, right wheel trails on the left side of planter; the right wheel leads, left wheel trails on right
side of planter.
RM/Coulter Combo: Install the RM/Coulter Combo assembly using hardware from the 2940-128 bolt bag. Mount the coulter blade on the
coulter arm hub & mount the RM wheels using the 5/8 Whiz Lock Nuts. RM wheels on combo units will install in the rear holes on both sides
on all rows. It is recommended to set the coulter blade at seed depth or above. Refer to diagram on pages 20 – 23
STEP 2: TABLET/ISOBUS IN-CAB INSTALLATION
If using a tablet, mount Tablet & 2940-111 RAM Mount in tractor cab. Position Tablet within reach during operation without compromising
safety/visibility from cab. The right rear corner post area is recommended so that the operator can see performance of residue managers
while making adjustments. In both applications, install 2940-153A harness by feeding the bare ends thru the harness access hole into the
cab. Bare ends get spliced to plug (not provided) that fits tractor's switched power source, splice red wire on 2940-153A to orange wire &
splice black wires together on each harness. Leave the 2 pin connector at the tractor hitch.
Refer to diagram on page 24
STEP 3: 2940-103A CONTROL BOX INSTALLATION
Mount control box in a safe location with mounts & hardware supplied. Mount the 2940-415 water separator/regulator assembly near control
box. Locate hydraulic compressor & drain all tank pressure. Plumbing in to the compressor can happen by A) installing a 2940-408 3/8PTC
elbow fitting in the bung on the side of tank, or B) find the 3/8 tubing that routes between the top of tank & valve manifold. Cut & install a
Tee into that airline. Measure & cut 2940-367 250psi rated airline & route from remaining port on the Tee to inlet fitting (water trap side) of
Yetter water separator/regulator assembly. Adjust regulator to only allow 100-120psi of clean, dry air beyond it. Measure & cut 2940-345
black airline from outlet fitting (regulator side) of water separator/regulator assembly to inlet fitting of control box. Route provided ¼" airline
from the elbow on the bottom of the water separator/regulator assembly to the ¼"PTC fitting on the bottom of control box. Route ¼" airline
from remaining ¼"PTC fitting on control box toward the ground, as this airline will dispense moisture. Refer to diagram on pages 25 & 32
STEP 4: CONTROL BOX HARNESS INSTALLATION)
Install 2940-166 VDM power cable with 40A breaker on tractor battery on the correct terminals, red = positive +, black = negative –. Connect
VDM power extension (2940-167 or 2940-168) & route to tractor hitch. Install the AUX PWR Harness, 2940-164A or 2940-165A. The 2 pin
connects to the 2940-153A from tractor cab, Anderson power connector connects to 8 gauge cable that routes to battery, & the black male 12
pin Deutsch connector connects to power harness connector on the side of the control box. If the 2940-103A control box is mounted at the back
of the planter, 2940-170A(10ft), 2940-171A(30ft), & 2940-430A(20ft) AUX PWR extensions will be needed. Refer to diagram on page 24
ISOBUS HARNESS (IF APPLICABLE) Install the 2940-655 harness to 2940-654 on Yetter control box. Use 2940-657 (15ft) & 2940-658
(30ft) extensions to reach where the ISOBUS is being tied in. On JD planters, use the 2940-659 to plug in at the back of planter where
terminating resister harness was located. On RCM I Ag Leader systems, plug into the ISOBUS connections near the center of the planter at
the Planter Control Module using the 2940-662 harness. On RCM II Ag Leader systems, route to tractor hitch & plug into back of tractor
using 2940-656. Refer to diagram on page 26
STEP 5: PLUMBING AIRLINES
A group of airlines that route to residue manager air bags are referred to as trunk airlines. Airline routing from RU, RD, & WT to trunk airline is
referred to as a supply airline. Start by routing trunk airlines: route black (down pressure) & blue (up pressure) airline on each wing/side of
planter. Start at end row of each wing, route airline to last row on wing & install in air bag, black airline = down pressure air bag, blue airline =
up pressure air bag. Follow airline back to end row cutting a tee in each airline at each row. When return back to end row, cut airline to length &
install into air bag. Install airline from each tee at each row & install in air bag for that row. If installing on a split row planter, keep trunk airline
on front rank residue managers on each wing plumbed separate from back rank. When plumbing in WT (wheel track) rows, use center 4 or 6
rows that plant over the tractor & planter wheel tracks. If equipping on a narrow transport planter with 4 center rows & 6 rows are desired on the
WT circuit, tie in the 1 row on each wing/side of the planter closest to the first & last center row. Install a tee in the center of each up pressure
trunk airline. Use tees to route/install blue airline from the RU port on control box to each tee in center of each up pressure trunk airline. Install a
tee into the down pressure trunk airline on the left wing & right wing. Route/install black airline from the RD port on control box to each tee in
center of left & right wing down pressure trunk airline. Install tee in center of center section down pressure trunk airline. Route/install airline from
WT port on control box to tee in the center of down pressure trunk airline on center of planter. If planter is dual rank, connect the trunk airline on
the corn rows to the trunk airline of the bean rows. Use 2940-342 ball valves between corn row trunk airlines & bean row trunk airlines to be
able to shut air supply off to bean rows when planting corn. Refer to pages 32 – 47
STEP 6: PERFORM A PRE-OPERATION TEST OF THE SYSTEM
Now that the system is installed, perform a pre-operation test. Start by folding/unfolding & lowering/raising the planter checking for slack in
airline & in harnesses at hinge points. Check all electrical connections, cables, & airline making sure nothing was damaged. Next, with the
tractor on, connect to the WiFi with your tablet or pull the Yetter screen up on the ISOBUS VT, & press the ACTIVE SYSTEM icon. The
compressor will turn on, build to 145psi (100-120psi on the cab controller) & shut off. Check the interior of the control box housing (valve,
fittings, & airline) for leaks. Apply 40psi to the RU port & watch your RMs as they should all raise to maximum up travel. Check for leaks on all
up pressure circuits & fittings. When that leak check is finished, turn RU to 0psi & turn RD & WT to 40psi. Check all down pressure airline &
fittings in these circuits for leaks & repair as needed. Refer to pages 53 – 54
