DISASSEMBLY & ASSEMBLY OF
MD-C SERIES BEARING HOUSING
DISASSEMBLY
The bearing housing features two sealed ball bearings along
with an outer magnet assembly. If further disassembly of this
unit is required, proceed as follows:
1. Refer to Figure 12 for part identification. Cover the open
end of the outer magnet with a piece sheet metal or
cardboard. This will keep foreign material out of magnet
area. Set the assembly face down with the shaft pointing
up and remove handknobs.
2. Remove external retaining ring from shaft, place unit
into press and push out shaft as shown in Figure 13.
Support end of outer magnet to prevent it from dropping
as possibly being damaged.
3. Remove the internal retaining ring and press out
bearings.
1. Place (1) bearing into housing bore. Gently tap or press
into bore. Position spacer in bore and insert second
bearing. Press down until bearings bottom out. Install
internal retaining ring into bearing housing.
2. Slide shaft of outer magnet assembly into bearing until
it meets resistance. Set upright in press (See Figure
14) and place a spacer on the end of housing such as
3” NPT coupling and press housing down until bearing
bottoms out on shaft shoulder. Install external retaining
ring on shaft of outer magnet assembly.
