NOTICE
• Flooded turbine motors - prove to be difficult to

repair if not addressed immediately after being
flooded. It’s difficult to impossible to flush the
contaminated hardened fluid from the bearing
air ports. If the unit cannot be cleaned up quickly,
then the bearings and or housing must be replaced.
Do not soak bearings in Ethylene-Glycol as it
will destroy the bearing substrate and pressed
in jets. The radial bearing may be soaked in a
solvent compatible with the paint intrusion. A use
of an Ultrasonic cleaner may aid in the loosening
of material. Do not let turbine components sit in
ultrasonics longer than 20 minutes. Some solutions
will etch the turbine motor components.

• During repair of multiple turbine motors DO NOT
MIX COMPONENT PARTS all rotor shafts are
matched with their spacer ring to provide correct
spacing for operation of the spindle.

• The spacers and the shafts are a matched set.
The number on the shaft must correspond to the
number on the spacer plate. See Figure 1-25.

• During tear down remove all O-rings and save in a
safe place until new O-ring kit is installed.

• Final rinsing of component parts should be made by
Isopropyl Alcohol.

INSPECTION OF PARTS

Figure 1-1: Rear Thrust Bearing and Shaft Thrust Area

Remove the rear cover screws with a
T10 Star wrench from rear of the turbine
motor and set aside.

Carefully lift off the rear thrust plate and visually
inspect the bronze bearing. If the bronze bearing
is extremely discolored 360 degrees around the
diameter this is an indication that the turbine
cannot be rebuilt without replacement of rear thrust
bearing (See Figure 1-2). If light damage such as
less than 90 degrees damage proceed to clean
up surface. See figure 1-1 for proper condition of
the assembly. Set aside the rear cover until later
rework process is covered.

Next, remove shaft rotor assembly from the
turbine housing. Examine the shaft’s outside
diameter for contact marks. (See Figure 1-3 New
Shaft Condition) Typically contact marks can be
found at the bottom of the shaft and at the top.
The contact marks consist of a bronze material
from the air bearings transferring onto the outside
diameter of the shaft.

If contact area observed 360 degrees around
the shaft diameter and it can be felt with your
fingernail as a raised area, then the shaft has
sustained too much damage to be cleaned up.
Return entire turbine motor to Ransburg for an
exchange rebuild unit. (See Figure 1-3A

Step 19

Lay out bearings for installation

Position Assembled Bearings:
Lay out bearings for install as shown. Note the
taper end goes inward towards the housing.
Remember the set screw holes must align with
bearing housing.

Install O-Rings:
Locate O-rings from replacement kit and install onto bearing
as shown in Figure 1-19. Please note new bearings may
need to be installed if required. New bearings are included
with the rebuild kits. (A12951-01)

NOTICE
• Prior to assembly, go back through and make sure

that all component parts are clean. If not, wash them
with 99% pure Isopropyl Alcohol and wipe with a lint
free cloth. All parts must be very clean. Use safety
glasses and latex gloves during cleaning operation.
Do not apply solvents to O-Rings, swelling will occur,
replace as needed with new kit.

Step 22

Step 21

Lightly lubricate bearing housing

Use Ransburg lubricant A11545 sparingly
enough (super thin film) to allow bearings to
slide into position. Too much lubricant could
lead to air bearing failure.

Slide Bearings into Housing:
Notice position of the taper on bearings, they
will be facing inwards during assembly.

Set Screw Hole Alignment:
Make sure to align both blind set screw
holes to bearing housing during the
insertion process.

Step 23

Install Set Screws into Bearings

Install New O-rings and spring:
Install new O-rings and spring onto set screws
as shown in Figure 1-23A.

Apply a drop of light duty thread retaining
compound to first thread (7969-05)

Install Assembled Set Screws into
bearing housing:
Visually inspect to make sure blind holes in
bearings are in alignment with housing. Once
in alignment, install both set screws and torque
into place 15-20lb.-in (1.3-1.6 Nm) torque.

Reminder: It’s critical to have proper align-
ment of set screws otherwise, they will not
fully seat allowing bearings to move yield-
ing premature bearing failure.

Locate Spacer and Shaft

Important Assembly Note:
Inspect spacer and shaft to make sure, that
they have corresponding serial numbers.
They are a matched set. If numbers do not
match locate ones that do match. Failure to
do so will result in turbine motor failure.

Step 27

Assemble Spacer Ring onto Bearing
Housing

Assemble Spacer & Second O-Ring:
Align pin on body with hole near bearing air.
Align spacer before installing shaft.
