Tractor PTO Installation
1. Secure the PTO coupling to the pump shaft by sliding the cou-
pling as far forward as possible without touching the bearing
shield and tightening the set screws down on the key of the
pump shaft. Slide coupling onto PTO shaft and secure by
pulling collar back on PTO quick coupler, sliding onto PTO
shaft and locking into place.
2. Check pump rotation. An arrow on the pump indicates proper
rotation direction.
3. To keep the pump from rotating with the shaft, set a torque arm
and short length of chain. Bolt one end of the chain to the
torque arm and secure the other to a stationary part of the trac-
tor. Be sure the chain is at a point directly above or below the
torque arm. Fastening torque chain to a point forward or back-
ward from pump center will create a bending force on pump.
Do not fasten pump rigidly to the tractor.
4. With the pump in position, connect the suction hose to the "IN"
port and the discharge hose to the "OUT" port. Make sure the
suction hose connection is tight. A loose connection will permit
air to be sucked in and the pump will not prime itself. Use at
least a 3/4" diameter hose on the suction line.
5. Use a large suction strainer with a 40 mesh minimum screen.
Either a Delavan #1700-2 suction strainer or a Delavan
#39908-2 Y type line strainer is recommended.
Engine Installation
The pump base can be mounted on a frame and aligned for either
direct-drive or belt and pulley drive. When mounting for direct-
drive, be sure pump and engine shafts are in alignment. A flex-
ible drive coupling will compensate for fractional misalignment.
When mounting for pulley drive, be sure the engine and pump
shafts are parallel. Align pulleys and keep them as close to the
shaft bearings as possible. For gasoline engine requirements,
follow engine manufacturer's recommendation.
Operation
1. With a clear suction line and open discharge line, the pump
should displace liquid within 15 seconds. A squirt of oil in the
suction side of the pump before starting will accelerate priming
action.
2. Never run the pump dry. Excessive heat will damage rollers
and seals.
3. Do not pump abrasive white wash, paints or other abrasive liq-
uids.
4. Do not use rusty supply barrels or sandy water.
5. Do not close the discharge line of the pump while it is running
unless a means of bypassing the liquid has been installed. A
simple relief or bypass valve can be easily installed in the dis-
charge side. A Delavan #37562 or #13895 pressure relief
valve is recommended.
Maintenance
1. Your Delavan pump is equipped with permanently lubricated
ball bearings. They do not require further lubrication.
2. Do not inject oil or grease into the two weep holes on the
underside of the bearing housings. These holes are to reveal
seal leakage and to prevent the solution from forcing its way
into the bearings. The holes must be kept clean.
3. AFTER SPRAYING — Thoroughly flush the pump with clear
water or use a solution of approximately one cup of ammonia
in 10 gallons of water. This will dissolve most residue remain-
ing in the pump. Squirt a light oil in the pump and rotate to
cover the inner surfaces with a protective film.
4. STORAGE. If the pump is to be out of service for several days
or stored, flush pump with clear water or use a solution of one
cup of ammonia in 10 gallons of water. Then pump a 50 per-
cent permanent antifreeze solution through the pump. Plug ports.
Caution: Do not use gasoline, kerosene, or fuel oil.
Pump Disassembly
Note: The numbers in parentheses used in the following
text are reference numbers that are found in the
exploded views.
1. With a screwdriver, remove snap ring (1). Lift out nameplate (2).
2. With a 9/16-inch wrench unscrew capscrews (3).
3. With cover plate down, cradle pump on "IN" and "OUT" ports
on fixture under an arbor press (Fig. 4). A cradle can be con-
structed of 2" x 4" lumber. Press the shaft and rotor assembly
(6) down through the pump body, bearing the seal. The shaft
and rotor assembly will remain in the end plate.
4. Lift off seal ring (4). Slide out rollers (5).
5. Check body for wear. File off any burrs that appear on rotor.
6. Make sure rollers (5) move freely in rotor slots. Replace rollers if
out-of-round, swollen or badly worn.
7. If further disassembly is required:
a. Press out shaft and rotor assembly (6) from end plate (7)
with an arbor press while supporting the end plate on a
cradle. Remove snap ring (1).
b. To remove bearing, use a small piece of brass rod and gen-
tly tap with hammer on the inner edges of the bearing. Drive
the seal out with a screwdriver and hammer. Discard seal.

4
Assembly
1. A repair kit including 4, 5, 6, 7 or 8 rollers, 2 seals, and a
seal ring is available (see parts list).
2. Position a new seal in seal housing with folded edge down.
Press seal down on outer edge until it "bottoms."
3. Position bearing (8) in bearing housing and press downward
until it "bottoms." Apply pressure to outer bearing race.
4. File off any burrs on the rotor faces and roller slots that may
have been caused by disassembly and handling.
5. Apply a light oil to shaft, end plate surface, and inside pump
body.
6. Press shaft and rotor into body, by easing the rotor shaft
through the seal; then press shaft with an arbor press while sup-
porting body bearing inner race.
7. Insert rollers (5), one in each slot.
8. Place seal ring (4) in groove.
9. Position end plate (7) for pressing down on pump body (10),
easing the shaft carefully through the seal. Carefully line up
matching holes of pump body and end plate.
10. Press pump together in an arbor press (Fig. 4), making sure the
pressing force is applied to the inner race of the ball bearing.
A sleeve with at least a 1 inch bore (that does not exceed 2
inches outside diameter) should be used.
11. Secure end plate with four capscrews (3).
12. After tightening capscrews, turn the shaft to make sure rotor is
not binding in pump. (It may be necessary to hold shaft in vise
when rotating body to check for binding.)
13. Tap shaft with a brass hammer. If this fails to center rotor, tap
the other end of the shaft lightly. The rotor should turn freely.

**Collar Coupler reduces possible vibration by clamping a full 360 degrees on the pump shaft & PTO. This better centers the pump shaft to the trac-
tor PTO, giving less chance of uneven wear. Both ends of the Coupler must be wrench-tightened onto the PTO & Pump shafts before operation.
NOTE: Do not force Coupler too far onto the PTO. After Coupler is in position, 1/4” - 3/8” of PTO should be visible.
***Do not use series 46814 Couplers for 5-Roller or Turbo 90 Pumps.

Important:
Whether you are returning your pump for warranty or for repair,
you must do the following:
1. Flush chemical residue from the pump (best done in the field).
2. Tag pump with type of chemicals having been sprayed.
3. Include complete description of operation problem, such as
how pump was used, symptoms of malfunction, etc.
Since pumps can contain residues of toxic chemicals these steps are
necessary to protect all the people who handle return shipments,
and to help pinpoint the reason for the breakdown.
