:Bronze

Impeller: Jabsco Neoprene Compound

Shaft: Stainless Steel

Shaft Seal: Carbon-Ceramic Face Type

Bearings: Sealed Ball Bearing

Ports: 1-1/4" ID Hose

Pulley: 6-1/2" Full Grip “A” Belt

Weight: 7 lb (3.2 kg)

INSTALLATION AND OPERATION

The pump may be mounted in any position.The direction

of rotation of the pump determines the location of the

intake and discharge ports (refer to dimensional

drawings). Before installing, rotate the pump shaft in the

direction of the normal operating rotation of the engines

on which the pump will be mounted. The mounting

bracket used to support the pump must be designed to

enable adjustment of the pump position for proper drive

belt tension.

Attach the pump to the mounting bracket using 3/8" –16

hex head screws.The pump mounting holes are tapped

to this thread size.

Put Pulley drive belt over both the drive pulley and the

pump pulley.An“A” section pulley belt should be sufficient

to drive the 18940-0010 pump. Position the pump to

allow 1/2" deflection of the drive belt midway between

the engine and pump pulleys.Secure the pump mounting

brackets. Attach 1-1/4"ID hose to the ports and clamp

using two stainless steel band clamps per port (be sure

to attach the water intake line to the proper pump port).

Be sure that all suction lines are airtight so that the pump

will self-prime. Start the engine and run at low speed.

This pump depends on the water for lubrication.DO NOT

RUN DRY for more than 30 seconds. Lack of water will

damage the impeller. This pump is designed for liquids

between 45° and 180°F.Pumping colder water will short-

en impeller life.

Cooling system should be designed so the cooling pump

operates with a maximum of 15 psi output pressure.

WINTERIZING

Drain the pump by loosening the impeller housing bolts

and loosening the housing.Flush cooling system with an

ethylene glycol base antifreeze. NOTICE: Do not use a

petroleum based rust inhibitor in the pump. Pump

damage can result.

APPLICATIONS

• Marine engine cooling

• Replaces Sherwood model G-5 for Chrysler engines

LM 318, LM 340, LM 360, LM 383, LM 400, LM 440

• Lehman 302, 351 C.I.

• Powerhouse Marine 302, 351 C.I.

* Average engine cooling applications have discharge

pressures of 10-15 psi (69-104 kPa) and intake

vacuums of 3-5 inches of mercury (76-127 mmHg).

SERVICE INSTRUCTIONS

DISASSEMBLY

1. Remove the three impeller housing screws (Key 13).

2. Slide impeller housing (Key 2) off the bearing

housing (Key 3) and shaft (Key 4) assembly.

3. Grasping hub of impeller (Key 1) with pliers, remove

it from impeller housing.

4. Remove cam screw (Key 12) from the impeller

housing. Slide the cam (Key 6) out of the impeller

housing.

5. Remove the O-ring (Key 7) from the impeller

housing groove. TO REMOVE SEAL ASSEMBLY,

THE SHAFT AND BEARING ASSEMBLY MUST BE

REMOVED FROM THE BEARING HOUSING (KEY

3).

6. Drive roll pin (Key 11) out of the pulley and shaft sub-

assembly.

7. Loosen set screw and remove pulley (Key 5) and key

(Key 16) from shaft.

8. Remove the retaining ring (Key 10) out of the

bearing housing (Key 3).

9. Lightly tap the spline end of the shaft. Shaft and ball

bearings (Key 9) should slide out of the bearing

housing. BE CAREFUL NOT TO DAMAGE SPLINE

END OF SHAFT.

10. Ceramic portion of the seal (Key 8) assembly normally

will stay on the shaft. THE BRASS/CARBON

PORTION OF THE SEAL SHOULD HAVE

REMAINED IN THE BEARING HOUSING. Lightly

press this portion from the pulley end of the bearing

housing toward the impeller end of the bearing housing.

11. Press ball bearings (Key 9) off the shaft by supporting

each bearing on its inner race to prevent damage.

ASSEMBLY

1. Clean and inspect all components for wear or

damage. Replace all components where needed.

2. Lightly lubricate pump shaft (Key 4) and press

bearings (Key 9) onto shaft by applying force to inner

race of the bearing. DO NOT APPLY FORCE TO

OUTER RACE OF BEARING.

3. Slide ceramic (white) portion of seal (Key 8) onto

spline end of shaft with large white face toward

spline end.

4. Lightly press the brass/carbon portion of the seal

into the bearing housing (Key 3); be careful not to

damage the carbon face of the seal. Brass face

should face toward impeller end of pump and be

pressed flush with bottom of counter-bore.

5. Lightly press shaft, bearing and shaft seal (ceramic

portion) subassembly into bearing housing; be

careful not to damage shaft end or seal components

during this assembly.

6. Replace bearing retaining ring (Key 10) into bearing

housing.

7. Slide pulley (Key 5) onto shaft. Make sure that roll

pin hole in shaft lines up with hole in pulley.**

8. Drive roll pin (Key 11) into pulley and shaft and

tighten set screw.

9. Apply a thin coat of sealant to convex side of cam

(Key 6) and threads of cam screw (Key 12), and

fasten cam to impeller housing.

10. Slide impeller (Key 1) onto shaft spline and place

spline seal in impeller.

11. Slide impeller (Key 7) into groove in impeller housing

and cam subassembly. Lubricate impeller bore.With

a twisting motion, slide the impeller housing over the

impeller. Be sure the direction the impeller blades

are bent matches the direction of normal engine and

pump rotation.

12. Fasten impeller housing to bearing housing with the

three machine screws and washers (Key 13 and 14).

13. TEST pump following instructions under Installation

and Operation section.

**If the roll pin hole cannot be aligned through pulley and shaft, drill a

new 1/8" hole for roll pin at an angle 45° from original hole. Center

punch pulley hub or file a flat spot on hub to ease start of drilling

procedure.
