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,
gasket and impeller, as outlined above. Loosen cam screw several turns.
Give cam screw a couple of sharp raps with the handle of the screwdriver
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 seal s eat
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 impeller, gasket and end cover as outlined
above. Tighten end cover screws. Tighten cam screw.
SHAFT SEAL REPLACEMENT, 11860-SERIES: Refer to major
repair instructions.
FIELD COIL REPLACEMENT: Remove drive belts from pulley. Remove
center bolt and washer from pulley (it may be necessary to remove end
cover to hold impeller from turning, while removing center pulley bolt).
Tap pulley with soft mallet to remove from shaft taper. Remove 3 bolts
and washers holding field coil to adaptor (11870) or body (11860).
Remove and replace field coil, tightening the 3 bolts securely. With drive
key in place in shaft, replace pulley assembly. Secure to shaft, replace
pulley assembly. Secure to shaft with center bolt and washer (again, it
may be necessary to hold the impeller from turning to tighten center
bolt). Replace drive belts. Do not over tighten belts. A deflection of 1/2"
midway between pulleys is generally considered normal.
MAJOR REPAIR: Remove pump from installation for major repair.
Disassembly: Remove end cover, gasket,impeller, cam and wearplate
as outlined in shaft seal replacement, 11870-Series. Remove clutch as
outlined in field coil replacement. Model 11870-Series: Use a punch to
drive roll pins (key 17) in toward shaft approximately 3/8" (10mm).
Remove clutch adaptor from body. Punch roll pin out of adaptor. Model
11860-Series does not have adaptor, clutch is secured directly to body.
Remove bearing to body retaining ring. Support bearing end of body on
arbor press platten. Press on impeller end of shaft to remove shaft and
bearing assembly from body. Use screwdriver to pry inner bearing seal
from body. Take care not to scratch or damage body bore.
11860-SERIES: Remove seal seat assembly from shaft. Support
impeller end of body on arbor press platten and, using suitable tube,
press seal out of seal bore towards impeller end.
11870-SERIES: Remove slinger from drain area. Carbon portion of
the seal assembly will be freed from shaft when shaft is remove from
body. Press seal seat assembly from bearing bore end towards
impeller bore.Remove bearing to shaft retaining ring. Support bearing
and press on clutch drive end of shaft to remove shaft from bearing.
ASSEMBLY: Support inner race of bearing on arbor press platten.
Oil shaft, insert drive end of shaft into bearing and press shaft through
bearing until it bottoms firmly against shoulder.Install shaft to bearing
until it bottoms firmly against shoulder. Install shaft to bearing retaining
ring in groove of shaft. Support impeller bore end of pump on arbor
press platten. Lubricate bearing seal with grease and press into bearing
seal bore, flush with bearing bore shoulder, with lip facing away from
bearing bore. For 11870-Series only: Insert slinger in drain slot, to be
picked up by shaft during shaft/bearing assembly. Insert splined end
of shaft through bearing seal (and slinger on Model 11870-Series).
Press on outer bearing race to assemble shaft/bearing assembly into
body, bottoming bearing firmly against bearing bore shoulder.Install
body to bearing retaining ring in groove in body with flat side against
bearing. For 11870-Series only: Install clutch adaptor in bearing bore.
If re-using adaptor previously disassembled from pump, line up dowel
pin holes during assembly of adaptor to body. If installing new adaptor
(which does not have pre-drilled dowel pin holes), insert into bearing
bore until it bottoms and use dowel pin holes in body to pilot drill dowel
pin holes through adaptor in two places, 180° apart. Clean any brass
chips from bearing area. Press roll pins into body to secure adaptor.
Attach field coil to adaptor (11870-Series) or body (11860-Series) with
three round head bolts. Turn body over and support on field coil.
11860-SERIES: Dip seal seat assembly, consisting of ceramic seal
seat and rubber washer, in water and push over shaft, with shiny side
of ceramic facing impeller bore, until bottoms firmly against shaft
shoulder. Press on outside edge of seal case with carbon seal face
towards ceramic seat to install seal assembly in seal bore. Press flush
with bottom of impeller bore.
11870-SERIES: Assemble rubber boot over ceramic seal seat so that
shiny surface of seal seat is outwards. Dip assembly in water and
insert into seal bore. Press firmly but carefully on seal seat until it
bottoms against shoulder of seal bore. Check to see that the seal seat
assembly remains in position and does not “pop” back out. A slight
twisting motion while pressing will seat it firmly in position.In this
pump, either a wave washer seal or coil spring carbon seal may be
used. The wave washer is used only if the carbon portion of the seal
does not have a coil spring attached.
Inspect shaft and seal seat bore to be sure sealing surfaces are free
of nicks or scratches. Clean shaft surface behind splines to ensure
proper O-ring seal on shaft. Apply light film of grease on shaft surface
behind spline area. Slide carbon ring assembly, with carbon facing
ceramic, over the shaft and firmly up against the ceramic seat. If
carbon portion of seal does not have an integral coil type tensioning
spring, slide wave washer over the shaft and against the rubber boot
on metal case containing O-ring and carbon. Install wearplate in
bottom of impeller bore, locating slot in outside edge of wearplate over
dowel pin in body. Apply a small amount of sealant to surface of cam
and cam screw threads and install cam in impeller bore. Edge of cam
should be flush with flange face of body. With a rotary motion in the
direction the pump will be turning, push the impeller into the impeller
bore until it is firmly bottomed. Turn body over to install clutch pulley
assembly. Press key into shaft. Position clutch/pulley assembly on
shaft aligning key with slot in pulley hub. Secure with bolt and washer.
To tighten bolt securely, it may be necessary to hold the impeller to
prevent the shaft from turning. Turn pump assembly over. Dip gasket
in water, position on pump flange face, install end cover and secure
with end cover screws.
