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.
