Appendix 5: Gear- Shaft Assembly
Description of Parts:
Shafts: As shown above, the pump contains two kinds of shafts: the drive shaft and the idler shaft. Both shafts have
retaining ring grooves and a keyway for positioning the gears. The drive shaft also has a set of retaining ring grooves
and keyway on one end for the inner magnet. The gears are positioned on the shafts using two retaining rings per
gear. Depending on the pump model, some shafts may contain an inner and outer set of grooves to fit both full (F)
and reduced (R) size gears. (See diagram below).
