Slinger and Shaft Seal Removal and Installation
The shaft seal provides environmental sealing for BulletinVPS motors. BulletinVPS motors are
shipped with a Fluoroloy shaft seal installed.
Lubricate the shaft seals with a food-grade polyurea base grease, such as Chevron FM (NLGI 2).
Lubricant is included in each shaft seal kit .
Remove the shaft seal by performing the following procedures. If a sealed gearbox is to be
attached to the motor shaft, perform only the Remove the Slinger procedure below.
Shaft Seal Kits
Shaft seal kit (with slinger) for Polytetrafluoroethylene (PTFE) shaft seals are shown below.
Remove the Slinger
1. Use two screwdrivers to carefully lever the slinger away from the faceplate of the motor.
You must create sufficient clearance to attach a wheel-puller, or a similar device, under
the slinger.
2. Center the wheel-puller on the motor shaft and position its arms under the slinger.
3. Slowly adjust the wheel-puller to lift the slinger off the motor shaft.
4. Dispose of the used slinger.
ATTENTION: Damage to the motor surface where the slinger and shaft seal make contact can
cause excessive wear and early failure of the slinger and shaft seal. Do not scratch or damage the
surface of the motor or the shaft.
Failure to observe these safety procedures could result in damage to equipment.
TIP Remove the shaft key, if the motor is so equipped, before performing the following steps. Refer
