PUMP DISASSEMBLY

1. Drain the liquid being pumped by removing the two

drain plugs (if present). Both are located in the bottom

of the casing. Once the liquid has drained, replace

the plugs.

2. Refer to Figures 5 and 6 for the names of parts.
3. Mark the head (40) and casing (31) before disassembly

to insure proper reassembly.

4. To inspect the head and pin assembly (39 and 40) and

idler and bushing assembly (37 and 38), remove the

head capscrews (43).

5. Remove the head from the pump. If the casing was not

drained in Step 1, be careful of the liquid draining out

between the head and casing. Do not allow the idler

to fall from the idler pin. Tilt the top of the pump head

back during removal to prevent this. Avoid damaging

the head shim set (63) since all shims are required to

maintain end clearance.

6. Remove the idler and bushing assembly. Inspect the

idler bushing for wear. If the idler bushing needs to

be replaced, see

“Installation of Bushings” on page

7. If further disassembly is required, proceed to the

next step.

7. Remove the four socket head capscrews (28) securing

the pump to the bracket. Support the pump with an

overhead hoist, if possible.

8. Use the jackscrews (14) in the bracket to separate the

inner magnet (57) from the outer magnet (58), see

sequence in

Figure 7. To keep the pump and bracket

assemblies properly aligned and for additional safety, it

is recommended to use 2 lengths of all-thread rod (6-8”)

threaded into diagonal capscrew locations in the adaptor

plate and slide through the corresponding holes in the

bracket.

WARNING!

Refer to DANGER & CAUTIoN listed on page 2

before proceeding.
