Turbodisk Applicator - Maintenance

Installation
Always check the inside of the motor housing and
clean, if required, with a minimum amount of an ap-
propriate cleaning solvent and a soft cloth.
1. Using a 1/16-inch Allen wrench, retract the three
(3) jack screws.
2. With o-rings in place on the nozzle plate and
housing, insert the turbine cartridge into motor
housing.
3. Secure the rotator assembly to the housing with
six socket head cap screws. Tighten the screws in
sequence until the cartridge is fully engaged into
the housing to prevent misalignment and possible
damage. Torque to 10 lbs•in.
5. With a 7/64-inch Allen wrench, remove six (6)
socket head cap screws, which secures the turbine
cartridge to the motor housing.
6. Using a 1/16-inch Allen wrench, turn each of the
three (3) jack screws, located next to socket head
cap screw, clockwise not more than one half turn at
a time in sequence to separate the motor from the
housing.
> Lightly lubricate o-rings with petroleum
jelly before assembly. Fit parts with
o-rings very carefully. They must not be al-
lowed to distort, unseat or break.

NOTES:
• Never use any silicone compound in this
system!
• Never use any lubrication on the bearings!
• Never use any solvent on the bearings!
• Never exert force on one race of a bearing
assembly that may be transmitted to the other
race through the bearings! Force and resist-
ance must always be on the same race in
order to prevent damage.
• Do not enlarge the nozzle passages during
cleaning, as it will effect performance.
• Always observe the specified torque in
tightening fasteners.
• Clean all parts thoroughly with an appropriate,
clean solvent. Inspect them for wear or damage
and replace as required.
• Check all flow passages for obstruction,
particularly the nozzle plate. Clear as required.
• Discard o-rings and replace with new. Lightly
lubricate o-rings with petroleum jelly before
assembly. Fit parts with o-rings very carefully.
They must not be allowed to distort, unseat, or
break.
> Failure to observe the following cautions
will result in diminished performance and
premature motor failure.

4. To avoid losing the jack screws during normal
operation, torque to 2-3 lbs•in (0.23-0.34 Nm).
Turbine Cartridge Service
This cartridge is a precision instrument and should
be handled with care. The bearings are preloaded to
30 lbs. (13-6 Kg) and dynamically balanced.
Turbine bearing unit must be returned to Ransburg
for rebuilding.
