Support the pump with an overhead hoist if possible. CAUTION ! Do not place your fingers between the pump mounting flange and the face of the bracket. Using extreme caution, pull the inner magnet away from the outer magnet (see figure 16).

Series MD – C80 Coupling 1. If the unit has a spacer coupling then the bracket of the mag coupling can stay bolted to base. Without the spacer coupling, either the reducer will need to be removed or the bracket unbolted. Remove the piping to the pump, provide a minimum of 4” of clearance beyond end of coupling shaft. Insert (2) 1/2” hand knobs which have a minimum of 4.5” of full threads into the two tapped holes at the 9:00 and 3:00 o-clock positions on the back of the bearing housing. Remove the (4) 0.

DISASSEMBLY / ASSEMBLY OF BEARING HOUSING PRESS 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. Cover the open end of the outer magnet with a piece of sheet metal or cardboard. This will keep foreign material out of the magnet area. Set the assembly face down with the shaft pointing up and remove the hand knobs. 2.

ASSEMBLY OF PUMP Use a suitable lubricant compatible with the fluid being handled when reassembling the pump. Inspect all parts, especially drilled holes in the casing for the suck back system, to make sure they are not plugged. Replace any worn parts, remove any burrs, and clean all parts before assembling the pump., 1. 5. Coat the idler pin with a suitable lubricant and place the idler on the idler pin in head. 6. The head can now be assembled onto the pump.

Be careful to keep the inner and outer magnets at least (1) foot apart until step 3. Do not engage magnets in any other fashion. 1. The outer magnet should be installed into the bearing housing, if not refer to DISASSEMBLY/ASSEMBLY OF BEARING HOUSING, page 10. Install the hand knobs so that 4” of threads are projecting below housing.

DISASSEMBLY – RELIEF VALVE Mark the valve and head before disassembly to insure proper reassembly. FIGURE 41 PRESSURE RELIEF VALVE INSTRUCTIONS 1. Remove the valve cap. 2. Measure and record the length of extension of the adjusting screw. Refer to “A” on Figures 43 and 44. 3. Loosen the locknut and back out the adjusting screw until spring pressure is released. 4. Remove the bonnet, spring guide, spring and poppet from the valve body.
