Assemble the INPRO labyrinth oil seal
1. Wrap electrical tape around the coupling end of the shaft to cover the keyway.
NOTICE:The edges of the keyway can be sharp. Make sure to cover the keyway with tape.
Failure to do so may result in cutting the O-ring and damaging the seal.
2. Lightly lube the shaft and the drive ring (4) with lubricant.
Lubricant helps in the installation process. Be sure that the lubricant is compatible with the
O-ring material and the pump-system standards.
3. Use an arbor press to install the outboard INPRO VBXX-D into the bearing cover with the
expulsion port (6) at the 6 o'clock position.
Press the outboard INPRO VBXX-D down to where the stator location ramp (9) starts to
avoid angular misalignment. There is a nominal 0.002 in. (0.051 mm) interference fit.
4. Discard any residual material from the stator gasket (5).
5. Complete the applicable step in this table depending on the model of your pump.
Pump model Action
STi Press the inboard seal along the shaft into the bearing frame.
All other models After you install the frame adapter on the bearing frame, press
the inboard seal over the shaft and into the adapter.
Assemble the C-face adapter
1. Mount the pump and the motor-coupling hubs if they are not already mounted.
2. Slide the C-face adapter over the pump shaft and mount it against the bearing-frame flange
using four bolts.
3. Mount the motor to the C-face adapter using either four or eight motor bolts.
