Stop motor before lubricating, do not over-oil or spill oil on

resilient motor rings. Do not force oil into cups, and stop if cup

fills before addition of specified amount.

Pump lubrication: Only applicable for pumps those are with

sleeve bearing sba and have oil cup for lubrication.

Immediately after pump is installed and before

running, slowly add the oil (sae 30 non-detergent

regular, supplied with pump) to pump oil cup, located

on top of bearing bracket:

s25 to s57, h32 to h5 4 and series 1050 (1b to 2b)

s69, h63 to h68, series 1060 (1½d to 3d)

At the start of each following heating season, lubricate with sae

30 oil for models s25 to s57, h32 to h5 4 and series 1050 (1b

to 2b), add approximately N oz. Lubricate every six months for

high temperature or constant operation. On models s69, h63

to h68 and series 1060 (1½d to 3d), be sure oil is visible at the

top and center of window on side of bracket and maintain this

level at all times.

Motor lubrication

caution

Stop motor before lubricating. Do not over-oil or spill

oil on resilient motor rings.

This motor has been lubricated properly at the factory. At

the start of each following heating season, however, on motors

with oil cups, add 15 drops sae 30 non-detergent oil to each

motor cup.

If the motor is fitted with grease fittings, follow the motor

manufacturer's recommended procedure. Motors without oil

cups or grease fittings are custom-greased for several years

operation and require little or no attention.

5 .0 seal replacement

Remove the pump bracket from the body. Remove the impeller,

damaged seal assembly, ceramic insert and rubber cup. Clean

the recess in bearing bracket coverplate and install a new re-

tainer cup and ceramic insert. Check the condition of the shaft

sleeve. If scored, replace the shaft assembly. Otherwise, clean

shaft extension and polish sleeve with a fine crocus cloth, using

a rotating motion, if required.

Press against the coupler end of the shaft to take up play while

pressing new seal firmly against the stationary face. A slight

amount of clean vaseline may be put on shaft sleeve to assist

installation. Press down firmly and evenly, using two screw-

drivers and pushing against the four ears of driving band (the

metal ring around rubber bellows), or around top outer edge

of driving band on models s25 to s57, h32 to h5 4 and series

1050 (1b to 2b).

Do not use spring washer on models s25 , s35 and h32 current

style circulators, where recess to locate spring is provided on

impeller hub.

Continue pressing against coupler end of shaft, re-mount

impeller and re-assemble the seal bearing assembly into body.

If necessary, install a new body gasket and clean gasket surface

of both volute and bracket.

caution

Before operating pump, carefully check:

1 Is the pump primed?

2 Is rotation correct?

3 Is pump properly lubricated?

4 Does the power supply agree with data on motor

name plate?

5 Is overload protection provided?

6 Is the system clean?

For domestic water systems use bronze body pumps.
