from cracks, grooves on the O .D and should fit inside a tee
housing cup (32) with a minimum of side to side movement .
√ inspect the inside of the cups (32) for grooves or surface
wear marks that could create a sealing problem .
√ inspect the inlet stem (3) for grooves worn in casting that
could prevent proper sealing .
Bearing Cup Removal: Insert tool # T-2 inside of tee housing and
line up stepped side of tool with the bottom end of one of the cups .
Using an arbor press, support the tee housing and press out cup . Repeat
procedure with remaining cup .
ASSEMBLY PROCEDURE
INLET STEM ASSEMBLY
Stand up inlet stem (3) in inverted position (3 bolt holes facing up) . Check
to see that the three 5/16 - 18 bolt holes are free of oil or water . Install
upper tee housing bearing (31); be sure to line up tab of bearing in notch
of inlet stem so that the bearing flange sits flat on the machined surface
of the inlet stem . Carefully install the tee housing seal (35) with the
spring facing up towards the 4 ports in the inlet stem . See Photo # 1 on
page 15 .
In cold temperatures, it is recommended that the seals be heated slightly
in warm water, so that they will fit over the inlet stem O .D . easily . It is
recommended that bearings and seals always be changed in pairs .
TEE HOUSING ASSEMBLY
Lubricate cup O .D . with a small amount of food grade gearbox oil . Using
tool # T-3 and an arbor press, press cup down into tee housing until the
flange is seated flat on the tee housing . Repeat procedure for other cup .
Wipe a small amount of food grade gearbox oil on I .D . of bearing cups .
This reduces the initial friction between the seals and cups . Invert tee
housing and place over bearing and seal on inlet stem .
Install lower seal, spring facing down towards the ports in the inlet
stem . Next, place the lower 31 bearing over the inlet stem with the tab
facing up .
Place tee housing bevel gear (10) on bearing . Line up notch on the I .D .
of the bevel gear with the tab on the bearing as shown in the photo
# 2 . Rotate the bevel gear (10) and the bearing (31) until the notch on
the bevel gear lines up with the locator mark on the inlet stem . The
assembly should match the photo # 2 at this point . Line up notch of ring
gear (see photo # 4) with drive lug on 5 tee housing (see photo # 2) .
Install the ring gear retaining ring (20); place one end into groove in tee
housing, then work the ring into the groove and press into place with a
small screwdriver . Be sure the retaining ring is completely seated in the
tee housing groove .
Place the 3 gearbox bolt o-rings (52) into the counter bores of the inlet
stem . Lubricate the o-rings and the 1" bore of the inlet stem with gearbox
oil . This will prevent twisting of o-rings during assembly .
GEARBOX ASSEMBLY
Install a new o-ring (55) on the upper rotor shaft bearing housing (47) .
Place the (47) into the top end of the gearbox (1) . Install a new o-ring (53)
on the gearbox, using a small amount of oil for lubrication .
NOTE: Flow-thru machines do not have a seal protector (45), or a seal
retainer (14) which has 2 (50) o-rings and 2 (52) seals.
For Lubricated Gearboxes: Invert the gearbox, and place the seal
protector (45) into the center bore of the gearbox . Install two (2) new
rotor shaft seals (37) and o-rings (50) on the seal retainer (14) . Lubricate
the o-rings and the bore of the gearbox, then place the seal retainer into
the gearbox until it is seated against the seal protector .
Installation of Center Rotor Shaft Bearing (46):
Replace o-ring (50),
and lubricate with oil . Place lower rotor shaft bearing (46) into center
bore of gearbox; and line up the flat on the flange with the large bore in
the gearbox . This is important to prevent interference with the geartrain .
Press down with your fingers until (50) o-ring is seated . Place tool # T-5
with a 12 oz . hammer or use an arbor press to seat the flange of the
lower rotor shaft bearing is against the gearbox bore face .
IMPORTANT NOTE: In order to maintain proper alignment between the
upper and center rotor shaft bearings, the flange of the lower rotor shaft
bearing (46) must be completely seated against the face of gearbox (1)
bore.
Inspection of Bearing Alignment: Place the #T-8 seal protector over
the end of the rotor shaft assembly (21), and insert the rotor shaft thru
the upper (47) and lower (46) rotor shaft bearings . The rotor shaft should
spin freely; if there is resistance, it is probably because the flange of the
lower rotor shaft bearing is not completely seated against the gearbox .
Reseat the lower rotor shaft bearing (46) with the tool # T-5, and test the
alignment once again .
ASSEMBLY OF GEARBOX TO INLET STEM
Check to see that the three 5/16 - 18 bolt holes in the inlet stem (3) are
free of oil or water . Invert the gearbox and line up the tab on the gearbox
(see photo # 3) with the notch on the bevel gear (10) . Once the tab and
notch are engaged, the gearbox can be rotated if necessary to line up the
bolt holes . If the bevel gear (10) is aligned properly with the locator mark
on the inlet stem, the gearbox bolt holes will be lined up with the inlet
stem bolt holes . Refer to photo # 2 . Apply a small amount of anti-seize
compound to the threads of the bolts . Install the 3 gearbox bolts with
lockwashers . Hand tighten bolts, then torque to 30ft/lbs for Stainless Steel,
23 ft/lbs for Bronze . If you do not have a torque wrench, tighten the bolts
until snug . Do not overtighten .
GEARTRAIN ASSEMBLY
Final Drive Gear Shaft Subassembly:
1 . Install the final shaft seal (38) into the final shaft bearing retainer
(15) with the spring facing upwards . Using an arbor press, press
the final shaft upper bearing (29) into the final shaft bearing
retainer (15) .
NOTE: the flow-thru type gearbox does not use the final shaft
seal (38).
2 . Align the square drive of the final drive shaft (18) with the square
of the final drive gear (25) . Press the drive gear onto the shaft
using an arbor press .
3 . Install a new o-ring (51) on the final shaft bearing retainer .
4 . Install the two gearsets on the shaft according to the type of gear
ratio . Refer to photos # 5, 6, and 7 . Be certain that the (23) gearset
with the undercut for the thrust washer (24) is on the bottom end
of the shaft, facing the gearbox cover (2) .
