drawing). Before installing, energize clutch and turn pump shaft in
direction of shaft rotation. Drive pump with two "A" size belts or one
"B" size belt. Avoid dry-running by using Vacuum Switch Model 4732-
0000 for automatic shutoff.

OPERATION
Pump will self-prime at low or high speeds. Make sure that all con-
nections are airtight. 12 Volt models are equipped with mechanical
clutch engagement screws in case of electrical failure. To mechanically
engage clutch, loosen locking nuts, tighten allen head screws and
retighten locking nuts. Reverse procedure to disengage clutch. If the
mechanical engagement feature is not desired, the screws may be
removed. DO NOT RUN PUMP DRY FOR MORE THAN 30 SECONDS.
LACK OF WATER FLOW MAY DAMAGE IMPELLER. To drain pump,
loosen end cover screws. See Head Capacity Table for head pressures
and flow. To avoid costly shutdowns, keep a Jabsco Service Kit on
hand.
SERVICE INSTRUCTIONS
IMPELLER REPLACEMENT: Remove end cover gasket. Pull impeller
out by grasping hub with pliers. With rotary motion in the direction the
pump will be turning, push the impeller into the impeller bore. A light
coating of grease in the impeller bore will protect the impeller during
initial dry start up. Install gasket and end cover.
SHAFT SEAL REPLACEMENT, 11870-SERIES: Remove end cover, gas-
ket and impeller, as outlined above. Loosen cam screw several turns.
Give cam screw a couple of sharp raps with the handle of the screw-
driver to loosen the cam from the impeller bore. Remove the cam
screw and cam (clean sealant from cam and impeller bore). Remove
wearplate with hooked wire. Remove marcel washer, seal assembly
and seat assembly from seal bore with hooked wire, taking care not to
scratch shaft or seal seat bore. Clean shaft surfaces behind splines and
inspect for scratches or wear. Replace if necessary. Before installing
new seal parts, clean any oil or grease from carbon and ceramic seal
faces. Dip seal seat and gasket assembly in water and press into seal
bore with boot first. Dip carbon seal assembly in water and install over
shaft, carbon towards ceramic seal seat, until it bottoms firmly against
ceramic seat. Slide marcel spring washer over shaft and against the
rubber boot (washer) on carbon seal assembly.
Replace wearplate, aligning notch with dowel pin in body. Apply
sealant to top surface of cam and cam screw threads and install cam
in impeller bore. Snug up but do not tighten cam screw. Replace
