NOTE: The bearing femperafure usuaiiy rises

affer regressing due to an excess suppiy of

g?ase. Temperafwee wiii refum to normal affer

pump has run and purged fhe excess from the

bearings, usually fwo to four hours.

For most operating conditions a lithium based mineral

oil grease of NLGI consistency No. 2 is

‘& (

recommended. This grease is acceptable for bearing

temperatures of 5’F to 230°F (-15°C to 110°C).

Bearing temperatures are generally about 2O’F (18’C)

Grease lubricated bearings are pre-lubricated at

the factory. F&grease bearings every 2000 operating

hours or 3 months.

Regrease Procedure:

NOTEz When regressing there is danger of

impurifies entering fhe bearing housing. The

grease container, fhe greasing device, and

fittings, must be clean. ’

1. Wipe dirt from grease fittings.

2. Remove 2 grease relief plugs (408H) from bottom

of frame.

( r-

Fill both grease cavities through fittings with

recommended grease until fresh grease comes

out of the relief holes. Reinstall grease relief

plugs (408H).

4. Ensure frame seals are seated in bearina housina

and if not press in place with drains locak at the

bottom .

Never mixgreases of different wnsisfency

(NLGI 1 or 3 with NLGI 2) or different thickener.

For example never mix a iifhium base grease

wifh a poiyurea base grease.

Pumpage temperatures above 350-F (177°C) should

be lubricated by a high temperature grease. Mineral

oil greases should have oxidation stabilizers and a

consistency of NLGI 3.

NOTE: If if is necessary to change grea,se type

or consistency, fhe bearings must be removed

and the old grease removed.
