Perform the following to remove and replace a Hale ESP for repair. Referenced bench procedures
are located at the end of this quick repair guide.
The following safety information (cautions and notices) apply throughout this entire procedure. Read
and understand all safety aspects before performing any maintenance activity. Notice: ONLY trained
personnel may perform the maintenance provided in this guide.
DISCONNECT THE BATTERY (OR TURN OFF THE MASTER BATTERY
SWITCH) PRIOR TO SERVICING THE HALE ESP. BATTERY CURRENT MAY CAUSE ARC-
ING, TEMPERATURES ABLE TO MELT METAL, ELECTRICAL BURNS, AND/OR ARC-
FLASH HAZARDS.
DO NOT LUBRICATE VANES OR VANE SLOTS. USING LUBRICANT ON
THE VANES OR VANE SLOTS DURING DISASSEMBLY, CLEANING, OR ASSEMBLY
EVENTUALLY CAUSES A GUMMY RESIDUE TO DEVELOP, RENDERING THE SYSTEM
INOPERATIVE.
IF IN 30 SECONDS (FOR A PUMP RATED AT 1250 GPM OR LESS) TO
45 SECONDS (FOR A PUMP RATED AT 1500 GPM OR MORE) ONE OF THE FOLLOW-
ING DOES NOT OCCUR STOP PRIMING THE PUMP AND CHECK FOR AIR LEAKS OR A
POSSIBLE ESP TROUBLE.
• THE DISCHARGE GAUGE READING INCREASES
• THE INTAKE GAUGE READING FALLS BELOW ZERO
• THE PRIMING PUMP DISCHARGES WATER TO THE GROUND
IF A PUMP IS OPERATED WITHOUT WATER FOR EXTENDED PERIODS,
OR WITHOUT DISCHARGING WATER, IT MAY OVERHEAT. FAILURE TO FLOW WATER
MAY DAMAGE THE MECHANICAL SEAL/PACKING OR THE DRIVE MECHANISM.
ALWAYS REPOSITION THE MOTOR COVER IF THE MOTOR VENT OPEN-
ING IS NOT ORIENTATED DOWNWARD (SEE FIGURE 3). FAILURE TO POSITION THE
VENT CORRECTLY MAY ALLOW WATER TO ENTER AND DAMAGE THE MOTOR.

Connect electrical connectors per tag(s).c.
Connect plumbing per tag(s).d.
5. Test ESP.
If required for test, connect vacuum gauge. (Most apparatuses already have a gauge. Ifa.
bench testing, add adapter and gauge directly to priming port.)
Exercise ESP to verify repair.b.
1) Prepare/configure apparatus (or ESP on bench) for a vacuum test.
2) Activate ESP. (If applicable, via SPV or PVG.)
NOTES: If vacuum gauge does NOT begin indicating a vacuum, stop test and check for leaks.
Typically, full vacuum is reached in <20 seconds (bench) or within 20 to 30 seconds
(apparatus).
Vacuum attained is permitted to be less than 22 in HG by 1 in HG for each 1000 ft
(305 m) of altitude above 2000 ft (610 m).
3) Run ESP until ESP pulls a vacuum (approximately 22 in HG or –0.75 bar).
Remove vacuum gauge if added to pump or ESP for testing.c.
6. Place apparatus in service in accordance with departmental procedures.

SB–156 5 Revision A
Determine Required Repair Kit
Table 1 lists two repair kits, however, only one kit will be required to restore the failed ESP to full
functionality. Use this procedure to determine which kit is required to return the ESP functionality.
1. Disassemble ESP as follows.
Note/match mark motor to pump head.a.
NOTE Record if the discharge port, ESP mount-
ing tabs, or suction port aligns with the
solenoid so the new pump head is orien-
tated correctly, when the ESP is installed
in the apparatus.
Separate pump from motor as follows.b.
See Figure 4.
1) Using 9/16-inch wrench, remove one [1]
3/8-in –16 X 2-1/2 in long screw.
Figure 4.
2) Using 9/16-inch wrench, remove nut from stud. (Typically, the stud will remove with the
nut. Otherwise, use jam nut method and remove stud.)
NOTES Do NOT allow the pump body to separate from the pump
head during removal.
Use of a non marring hammer may be required to sepa-
rate the pump head from the motor.
3) Remove assembled pump head/body from motor.
2. Inspect motor drive tang for damage/wear. See Figure 5.
NOTE If the drive tang in the motor is unserviceable, discard the
entire ESP and replace it with a new ESP. The drive tang
is unserviceable if one side of the tang is missing, or if
the shaft is cracked or split at the base of the groove, this
allows the tang to widen. Burring may be repairable.
Figure 5.
3. Separate pump head from pump body as follows. See Figure 2.
Place pump on work surface with pump body downward. See Figure 6.a.
NOTE Do NOT allow the vanes to fall out of the rotor during pump head removal.
IF SHAFT (TAB) HAS BEEN BURRED BY THE MO-
TOR (DRIVE TANG), REMOVE THE BURRING BEFORE REMOV-
ING THE ROTOR/SHAFT FROM THE PUMP HEAD. DO NOT
FORCE THE SHAFT THRU THE PUMP HEAD. FORCING THE
SHAFT THRU THE HUMP HEAD MAY DAMAGE THE DU BEAR-
ING IN THE PUMP HEAD.

Hold rotor shaft in place and lift pump head off pump bodyb.
and rotor shaft. See Figure 7.
Hold vanes in place in rotor slots and lift rotor (with vanesc.
in place) out of pump body.
4. Inspect end of pump body (around bearing) and pump head
(also around bearing) for scarring/scoring from rotor or vane
contact.
Figure 7.
NOTE: See Figure 8 for a sample of the typical acceptable ESP wear pattern.
Figure 8.
If the pump body or pump head exhibit scarring/scoring (caused by rotor or vane contact) the pump
is unserviceable, discard the entire pump head assembly and perform Replace Pump Head Assem-
bly (ESP Bench Procedure) using the 502–0061–50–0 repair kit (Table 1).
If the pump body and pump head is serviceable, discard the vanes and shaft seal and perform Re-
place Vanes And Shaft Seal (ESP Bench Procedure) using the 546-1410-03-0 repair kit (Table 1).

Replace Pump Head Assembly (ESP Bench Procedure)
This bench procedure is NOT intended to be performed as a stand along procedure. If the ESP re-
quires removal from the apparatus, begin with Step 1. of the main procedure (see Page 3 and per-
form the main and bench procedure(s) in the order instructed. If the ESP is already removed from the
apparatus (or is being repaired in place), begin with Determine Required Repair Kit (Page 5) and per-
form the bench procedure and the remaining portion of the main procedure in the order instructed.
As stated at the bottom of page 5, if the pump body or pump head exhibit scarring/scoring (caused
by rotor or vane contact) the pump head assembly is unserviceable. If the pump head assembly is
unserviceable, discard the entire pump head assembly and perform this bench procedure using the
502–0061–50–0 repair kit (Table 1).
DO NOT LUBRICATE VANES OR VANE SLOTS. USING LUBRICANT ON
THE VANES OR VANE SLOTS EVENTUALLY CAUSES A GUMMY RESIDUE TO DEVELOP,
RENDERING THE SYSTEM INOPERATIVE.
1. Grease motor shaft slot and rotor shaft tang.
2. Assemble ESP as follows.
NOTE When installing a pump head assembly that has been repaired using the Replace
Vanes And Shaft Seal (ESP Bench Procedure) consider the assembly to be a new
pump head assembly for the purposes of this procedure.
Place new pump head assembly (assembled pump head and pump body with rotor, vanes,a.
bearings, and shaft seal) on to motor.
1) Rotate pump head until motor and pump shafts mate (so tang and slot align with each
other).
See Figure 5 (motor) and Figure 6 (pump).
2) Rotate motor and/or pump head until mounting bolt holes align according to note/match
marks.
3) Verify pump head and motor are mated as originally noted (discharge port, ESP mounting
tabs, or suction port aligns with the solenoid). Correct orientation if required.
Install retaining hardware.b.
1) Hand start one [1] 3/8-in –16 X 2-1/2 in long screw.
2) Hand start one [1] 3/8-in –16 nut on stud. (If stud is separated from the nut use jam nut
method to install stud first. Then install nut. ONLY torque the nut.)
3) Using 9/16-inch open end wrench, tighten screw and nut.
4) Using a 9/16-inch torque wrench, torque screw and nut to 23 lb-ft.
Return to main procedure, Step 4 (on Page 4) to install ESP on apparatus.

Replace Vanes And Shaft Seal (ESP Bench Procedure)
This bench procedure is NOT intended to be performed as a stand along procedure. If the ESP re-
quires removal from the apparatus, begin with Step 1. of the main procedure (see Page 3) and per-
form the main and bench procedure(s) in the order instructed. If the ESP is already removed from the
apparatus (or is being repaired in place), begin with Determine Required Repair Kit (Page 5) and per-
form the bench procedure and the remaining portion of the main procedure in the order instructed.
As stated at the bottom of page 5, if the pump body or pump head do NOT exhibit scarring/scoring
(caused by rotor or vane contact) the pump head assembly is serviceable. If the pump head assem-
bly is serviceable, discard the vanes and perform this bench procedure using the 546-1410-03-0
repair kit (Table 1) to replace the shaft seal, install the new vanes, and assemble the ESP.
DO NOT LUBRICATE VANES OR VANE SLOTS. USING LUBRICANT ON
THE VANES OR VANE SLOTS DURING DISASSEMBLY, CLEANING, OR ASSEMBLY
EVENTUALLY CAUSES A GUMMY RESIDUE TO DEVELOP, RENDERING THE ESP INOP-
ERATIVE.
1. Remove all four vanes. See Figure 9.
2. Install four [4] new vanes as follows. See Figure 7 and Figure 9.
Place pump body on its end (pump head mating surface facing up). Placea.
rotor in pump body (tang end facing up).
Position each new vane to align with a slot in rotor.b.
Slide vane into slot until bottomed in slot.c.
Figure 9.
Repeat Step b. and Step c. (above) until all four new vanes are in place.d.
NOTES The vanes must move freely in the rotor slots. Do NOT be concerned if the vanes try
to fall out of the rotor slots due to gravity. Hold the vanes in place until the pump
body is in place to hold them in their slot.
Keep pump body standing on its end to maintain vane positions
while ESP is assembled. See Figure 7.
3. Remove and discard shaft seal. See Figure 2 and Figure 10.
4. Install new seal (Figure 11).
Lightly grease seal and bore of pump head. (Prevents seal damagea.
and aids in assembly.)
Figure 10.
Position new seal with metal cup facing DU bearing (down).b.
Refer to Figure 11.
Drive seal in to pump head as follows.c.
1) Align seal with pump head bore. (Seal must be level with and square to
the bore before/during driving the seal into the bore.)
Figure 11.
NOTE A bearing driver larger than 22 mm will NOT seat the seal all-the-way and a driver
smaller than 20 mm will damage the seal. Use ONLY a 20 or 22 mm driver.
2) Using a 20 to 22 mm bearing driver and a non marring hammer, gently tap seal driver
until seal seats against DU bearing.
