Pressure Relief Procedure
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure in your spray gun
manual or in the SuperCat instruction manual.
Disassembly
1. Relieve the pressure.
2. See your spray gun manual to remove the power
cartridge. For the SuperCat alternator, remove six
screws, open the housing, and remove the power
cartridge.
3. Remove the turbine alternator.
4. Test the Coil: Measure the resistance between the
two outer terminals of the 3-pin connector (101a).
The resistance should be 2–5 ohms. Measure the
resistance between each outer terminal of the
3-pin connector and the turbine alternator housing
(B). The resistance should be infinite. If the readings vary from these values, replace the coil.
5. Remove the plastic plug (A).
6. Pro Xs Models only: Remove the retaining ring
(H) from the turbine alternator housing (B).
7. Insert a center punch or small metal shaft into the
hole in the back of the turbine alternator housing
(B). Hold the housing and lightly tap out the turbine
assembly (G).
8. Remove the larger bearing (2).
9. Slide the coil assembly (101) off the armature (D).
Inspect the coil for wear or damage and replace if
necessary.
NOTE: If only replacing the coil (101), continue by
following steps 5 through 11 on page 3.
10. Using a drift punch or small metal shaft, tap the
armature (D) out of the bearing (1) and fan (3).
CAUTION
To avoid demagnetization of the armature (D), never
place it in contact with, or in close proximity to, any
other armature or other ferromagnetic objects.
11. Clean the armature (D) shaft with a soft cloth.
Inspect the shaft for wear or damage. Replace the
armature (part no. 217590) if necessary.

Assembly
1. Remove the bearings (1 & 2) from the package
and wipe the excess oil off with a soft cloth. Do not
use solvent or air to wipe or blow off the excess oil.
2. Place the smaller bearing (1) [marked 197906] on
the long end of the armature (D), with the machined groove in the bearing facing the armature.
3. Install the fan (3) on the long end of the armature
(D), with the machined groove in the fan facing
away from the armature.
4. Insert the spacing tool (4) between the fan (3) and
bearing (1). Lightly tap on the end of the armature
(D) until the fan is pressed up against the spacing
tool and bearing. Remove the spacing tool. When
properly installed, the bearing (1) should spin
freely on the armature shaft.
5. Install the coil assembly (101) over the armature
(D), with the 3-wire connector (101a) facing away
from the fan (3).

NOTE: The items referenced with
numbers are included with a kit.
6. Place the larger bearing (2) [marked 197907] on
the end of the armature (D), with the machined
groove in the bearing (2) facing in toward the
armature. Align the legs of both bearings with each
other.
NOTE: When installed, the bearing legs must not block
the exhaust ports of the turbine alternator housing (B)
or the gun will not operate properly.
7. Carefully slide the turbine alternator housing (B)
over the turbine assembly (G), aligning the bearing
legs between the exhaust ports of the housing.
Push the turbine alternator housing onto the
turbine assembly until the assembly is seated
firmly in the turbine alternator housing.
8. Pro Xs Models only: Install the retaining ring (H)
in the turbine alternator housing (B).
9. Press the plastic plug (A) onto the back of the
turbine alternator housing (B).
10. Install the turbine alternator on the power cartridge
as instructed in your spray gun manual.
11. Install the power cartridge and assemble the gun.
