Turbine Cartridge Service
This cartridge is a precision instrument and should
be handled with care. The bearings are preloaded
to 30 pounds and dynamically balanced to 0.01
grams•in or better.
Turbine field repair or rebuild ONLY after factory
warranty expires. Any attempt to disassemble turbine
during the warranty period will void the warranty.
>
Bearings used in this cartridge contain
special grease that is available exclusively to
Ransburg. The purchase of replacement bear-
ings from sources other than Ransburg is not
recommended.
NOTE
With a 5/16-inch wrench, loosen the six
captive retaining screws used to hold the
upper and lower sections together. Note:
As the last screw releases, the lower unit will
drop only enough to allow for the bulkhead
plates to be separated. The two latching
mechanisms on the bulkhead plates will hold
the unit in place until the operator is ready
to move the lower section to a proper work
place.
5.
Once the lower fluid section is placed in
a stationary condition, the removal of the
cartridge can be continued.
6.
Next remove screws holding the fluid tube
assembly.
7.
With a 7/64-inch wrench, remove six socket
head cap screws, which secures the turbine
cartridge to the motor housing.
8.
Using a 1/16-inch wrench, turn each of the
three 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.
