the cups may need to be replaced . This is dependent on the type
of cleaning solution, pressure and the regularity of inspection and
preventative maintenance .
Rotor Shaft Bearings: The upper and lower bearings that support
the rotor shaft can easily be inspected while the machine is fully
assembled . To inspect the upper and lower rotor shaft bearings (47
and 46), remove the stator (7) . Rotate the rotor shaft by turning the
rotor (7) with your finger or a screwdriver . If the bearings allow side to
side movement so that the rotor is contacting the inlet stem wall, then
the bearings need to be replaced . Refer to Disassembly Procedure
on page 8-10 and Assembly Procedure on page 10-12 for details on
parts replacement .
Gearbox Bearings:
There are six bearings inside the gearbox,
which maintain the gear shaft alignment . Removal of the gearbox
cover (2) and the geartrain allows for inspection of these bearings .
If there is notable side to side play of one of the gear shafts (# 17,
18 or 20) and one of the mating bearings (# 26, 27, 28, 29, 30) then
replacement is recommended . Refer to Disassembly Procedure on
page 8-10 and
Assembly Procedure
on page 10-12 for details on
parts replacement .
NOTE: While it may appear that the gearbox bearings are standard off-
the-shelf bearings, they have all been modified by the manufacturer
to meet the design specifications set forth by the manufacturer.
Replacement of these bearings by any type other than Spraying
Systems Co. parts can compromise the performance of the machine.
DISASSEMBLY PROCEDURE
During disassembly of TankJet 360 series, several inspections can be
made which aid in determining a preventative maintenance schedule
or in troubleshooting, should there be a problem . If you have already
disassembled a machine, read through the disassembly procedure
then refer to the Assembly Procedure section beginning on page 10-
12 . Item numbers are shown in parentheses . A check mark √ precedes
an inspection of a part or assembly . If upon your inspection you find
something that differs from what is normal in a new part or assembly,
make a note of it, and then continue the disassembly procedure . At
the end of the disassembly, compare your notes to the troubleshooting
guide at the back to find a solution .
STATOR (8) AND ROTOR (9) REMOVAL
With machine standing upright, remove stator retaining ring (39) with
needle nose pliers . Lift out stator (8) with pliers or by hand .
√ check to see that rotor shaft spins free: rotate the rotor
shaft by turning the rotor with your finger or a screwdriver .
It should spin freely with minimum pressure, and the tee
housing (4) will spin slowly .
√ check free play of tee housing up and down on the axis of
the inlet stem (3) . If there is no movement, there could be
scale or deposits trapped between the main tee housing
bearings and the bearing cups, or the unit has been
assembled incorrectly . Take note if there is no free play
and refer to the troubleshooting guide for assistance .
NOZZLE HOUSING ASSEMBLY (5) REMOVAL
√ check the nozzle housing for free play (in and out) on the
axis of the tee housing nose (4) . If there is no movement,
there could be scale or deposits trapped between the
nozzle housing bearings and the bearing cups, or the
unit has been assembled incorrectly . Take note if there
is no free play and refer to the trouble shooting guide for
assistance .
Nameplate Removal:
the nameplate screws (58) with a 7/16"
socket or end wrench . Grasp the nozzle housing assembly with one
hand and gently pull off the tee housing (4) . If the nozzle housing does
not come off easily or if there was no free play, there may be deposits
or scale built up between the cups (34) and the bearings (33) . If so, use
a plastic hammer to gently tap on the nozzle housing to loosen it, then
remove from tee housing . The nameplate (6), outer bearing (33), and
seal (36), will come off with the nozzle housing assembly . Remove the
inside bearing and seal from the tee housing .
NOTE: Because the flange of the inside bearing is locked into the
groove on the tee housing, it is necessary to rotate the bearing to
loosen the flange. Use two (2) screwdrivers to gently pry up on the
flange of the bearing until you can grasp it with your fingers.
Inspect the seals to be sure the jacket has not worn down thru to the
spring .
√ examine the bearings for wear . They should be free
from cracks, grooves on the O .D and should fit inside a
nozzle housing cup (34) with a minimum of side to side
movement .
√ inspect the inside of the cups for grooves or surface wear
marks that could create a sealing problem .
Remove the bevel gear retaining ring (19); pry one of the ends out of
the groove on the nozzle housing with a small screwdriver, working
your way around until it is completely removed . Remove the bevel
gear and the (49) o-ring .
√ visually inspect the nozzles; look down the end of the
nozzle with the aid of a flashlight to see that there is no
blockage of the stream straightener .
Remove the nozzles for cleaning if necessary using a large adjustable
wrench or a pipe wrench .
Bearing Cup Removal: Before removal of the bearing cups, the
bevel gear (11) should be removed . Insert tool # T-1 thru the bearing
cup on the bevel gear side of the nozzle housing at a slight angle . Then
line up the stepped side of T-1 with the bottom end of the cup . Using
an arbor press, support the nozzle housing and press out cup . Insert
tool # T-1 and remove remaining bearing cup .
GEARBOX COVER (2) REMOVAL
Invert machine so that the gearbox cover (2) is facing up . Remove the
2 gearbox cover screws (56) and lockwashers (57) . Insert a stiff blade
putty knife between the gearbox (1) and gearbox cover (2); tap on the
end with a small hammer, then pry up on gearbox cover until the o-ring
(54) is visible . Slowly lift the gearbox cover while holding the idler
shaft (17) which may be lifted with the gearbox cover due to suction
of the lower idler shaft bearing (28) .
If the idler shaft is pulled out with the gearbox cover, the idler gearsets
may disengage from the rest of the geartrain . If this occurs, simply
remove the loose gearsets after the oil has been drained from the
