JABSCO 1673-Series User manual

Direct Drive – Clearance should be left between drive shaft
and pump shaft when installing coupling. Always mount and
align pump and drive shaft before tightening the coupling
set screw.
3. SPEEDS – 100 RPM to the maximum shown in the perfor-
mance table. Consult the factory for operation at speeds
above those shown. For longer pump life, operate at
lowest possible speeds.
4. SELF-PRIMING – Primes at low or high speeds. For
vertical lift of 10 feet (3.0mm), a minimum of 800 RPM
is required. Pump will produce suction lift of up to 22 feet
(6.7m) when wetted. BE SURE SUCTION LINES ARE
AIRTIGHT OR PUMP WILL NOT SELF-PRIME.
5. RUNNING DRY – Unit depends on liquid pumped for
lubrication. DO NOT RUN DRY for more than 30 seconds.
Lack of liquid will damage the impeller.
6. NOTICE – Do not pump light fraction petroleum derivatives,
solvents, thinners, highly concentrated or organic acids.
Damage to pump may result. Consult Jabsco Chemical
Resistance Table, available upon request from Jabsco,
for proper body materials and impeller compounds. If
corrosive fluids are handled, pump life will be prolonged if
pump is flushed with water after each use or after each
work day.

APPLICATIONS & OPERATING INSTRUCTIONS
MARINE: Engine cooling, Pumping bilges, Washdowns,
Circulating water in bait tanks, Utility dock side pump.
INDUSTRIAL: Circulating and transferring, Velocity-mixing,
Pumping machine tool coolants, Return spill, Sump
drainage, Chemicals, Pharmaceuticals, Soap, Liquors, Ink,
Dyes, Alcohol, Various acids, Tanning liquors, Glycerine,
Brine, etc.
FARMING: Pumping water for stock, Pumping water from
shallow wells and cisterns, Pumping liquid ballast into
tractor tires.
PLUMBING AND HOME EMERGENCY USE: Pumping out
flooded basements, Cesspools, Sumps, Water heaters and
water closets, Drains and sinks, Draining fishponds and
pools.
1. INSTALLATION – Pump may be mounted in any
position. Intake and discharge ports are determined by
the direction of shaft rotation (refer to Dimensional
Drawing). Before installing, turn the pump shaft in the
direction of the operating rotation.
2. DRIVE – Belt or Direct with flexible coupling.
NOTICE: Do not press pulley or coupling on the
shaft without supporting the shaft at the opposite
end to prevent its movement into the impeller bore.
Belt Drive – Overtight belt load will reduce pump
bearing life.

OPERATING INSTRUCTIONS (Cont.)
7. PRESSURES - Consult Head Capacity Table for
recommended maximum for continuous operation. If
pressures exceed those shown, consult the factory.
8. TEMPERATURES - Neoprene 45°-180° F (7°-82° C),
Nitrile 50°-180° F (10°-82° C).
9. FREEZING WEATHER - Drain unit by loosening end
cover.The following anti-freeze compounds can be
used without any adverse effects to the neoprene impeller:
Atlas “Permaguard”, DuPont “Zerex” and “Telar”, Dow
Chemical “Dowguard” and Olin Mathison “Pyro
Permanent”. Most methyl alcohol (methanol) based
antifreeze can be used with neoprene. (DO NOT USE
PETROLEUM BASED ANTI-FREEZE COMPOUNDS
OR RUST INHIBITORS.)
10. SPARE PARTS - To avoid costly shut downs, keep a
JABSCO Service Kit on hand.

EXPLODED VIEW

DISASSEMBLY
1. Remove end cover screws, end cover and O-ring.
2. Remove impeller by grasping hub with water pump pliers.
3. Loosen cam screw and remove cam (clean off sealant).
4. Remove pulley or coupling and key from shaft.
5. Remove retaining ring which secures bearing shaft
assembly to pump body.
6. From impeller end of pump, press bearing and shaft
assembly out of bearing bore.Remove slinger from shaft.
7. From drive end of pump, press the seal out of the
seal bore.
8. It bearings or shaft need to be replaced, carefully
insert two equal size slot screwdrivers between bearings
180 apart. Simultaneously twist screwdrivers in
opposite directions to separate bearings. Continue to
push bearings off of shaft taking care not to
damage bearings or scratch shaft.
9. Remove snap ring that positions the bearings on the
shaft.
NOTE: Inspect all parts for wear or damage and
replace where necessary.
ASSEMBLY
1. Install bearing positioning snap ring on shaft.
2. Press bearings (one from each end of shaft) onto
shaft and against positioning snap ring. Slide slinger
onto impeller end of the shaft and position against
raised shoulder near bearings.
3. Press seal (with lip pointing toward impeller bore) into
seal bore in pump body. Ensure it is seated in bottom of
seal bore.Lubricate seal lip with a small amount of
grease.
4. Align impeller end of shaft with the seal and press
shaft/bearing assembly into the bearing bore (push
on bearing outer race). Install bearing retaining ring
in retaining ring groove With concave side facing out
toward drive end of shaft.
5. Apply a thin layer of sealant to screw threads and
top of cam and install in body. Secure with cam
screw.
6. Lubricate impeller bore with light coat of water pump
grease and start impeller into bore with a rotary
motion, until impeller screw engages slot in shaft,
then push into bore.
7. Install O-ring and end cover.Secure with end cover
screws.
