TEMPERATURES:
Neoprene: 45°-180° F (7°- 82° C)
Nitrile: 50°-180° F (10°- 82° C)
Natural Rubber: 33°-120° F (0.6°- 49° C)

FREEZING TEMPERATURES
– Drain unit by loosening end
cover. The following anti-freeze compounds can be used
without any adverse effect to the neoprene impeller: Atlas
“Permaguard”, DuPont “Zerex” and “Telar”, Dow Chemical
“Downguard” and Olin Mathison “Pyro”. Most methyl alcohol
(methanol) based antifreezes can be used. DO NOT USE PETRO-
LEUM BASED ANTI-FREEZE COMPOUNDS OR RUST INHIBITORS.
10.
GASKET
– use standard pump part. A thicker gasket will reduce
priming ability. A thinner gasket will cause impeller to bind.
Standard gasket is 0.015” thick.

SPARE PARTS
– To avoid costly shut downs, keep a Jabsco
Service Kit on hand.
SERVICE INSTRUCTIONS
DISASSEMBLY
1.

3.
Remove seal with hooked wire. Remove seal seat and gasket.
4.
Loosen cam screw and remove cam. Clean off sealant.
5.
Remove wearplate.
6.
Insert screwdriver between OD of outer bearing seal and
pump bore and pry out seal.
7.
Remove bearing to body retaining ring.
8.
Press on impeller drive end of shaft to remove shaft and
bearing assembly. Heating outside of body at bearing will ease
disassembly.
9.
Remove bearing-to-shaft retaining ring.
10.
Supporting bearing inner race, press shaft through bearing.
11.
Using extreme care not to damage bore, insert screwdriver
between OD of inner seal and pump bore and pry out the seal.
NOTE: Inspect all parts for wear or damage and replace if
necessary.
ASSEMBLY
1.
Lubricate inner seal with grease and press into body bearing
seal bore with lip facing away from bearing bore.
2.
Press shaft into bearing, using care to support inner race of
bearing.
3.
Install bearing-to-shaft retaining ring with flat side toward
bearing.
4.
Position slinger in body drain area on 6400-Series pumps only.
Insert splined end of shaft through bearing bore and guide
slinger over shaft until bearing contacts body.
5.
Pressing on bearing outer race, install bearing and shaft
assembly into bore.
6.
Install bearing to body retaining ring in body groove with flat
side toward bearing.
7.
Lubricate outer bearing seal with grease and press into
