Outer Drive Replacement
1.
Remove the setscrews (item 15B) from the side of the drive (NEMA motors) or the bolt, lock washer
and flat washer (items 32, 33 & 34) from the center of the drive (metric motors).
WARNING: Be careful, tools will want to be attracted to the magnets.
2. Remove the drive magnet from the motor shaft by gently prying up from the bottom of the drive.
See figure 32.
3. To reinstall the drive or a new drive follow the instructions from Section I - Assembly, Pumps without

Section VI - Clamp Ring Replacement & Reassembly
1.
Inspect the clamp ring. If clamp ring requires replacement, it is
recommended to remove the plastic foot (Item 14) first. Note:
100/112 frame B5 adapters do not use the foot. See figures
33 & 34. Remove the 4-M6 bolts (items 25 thru 31).
2. Remove the (5) M8 bolts, lock washers & flat washers (items
22, 23, & 24) from the clamp ring (item 11). See figure 35.
Remove the clamp ring from the motor adapter. There is a snug
fit between the clamp ring & motor adapter due to the vapor
protection o-ring (item 12). Carefully pull the two parts apart.
See figure 36.
3. Inspect the motor adapter o-ring (item 12). If damaged, replace.
If reusable, lubricate it with a chemically compatible lubricant.
See figure 37.
4. Install the new clamp ring.
Place the clamp ring on a
flat surface. See figure 38.
Align the bolt holes (5 motor
adapter and 2 foot bolt
holes) on the clamp ring with
the bolt holes on the motor
adapter. Push the motor
adapter straight down onto
the clamp ring to seat the
o-ring. See figure 39. Install
(5) M8 bolts, lock washers
and flat washers (items 22, 23
& 24), and tighten & torque in
a star pattern to 130 in-lb (14.7
N-m). See figure 40.
