NOTE: More bearing failures are caused by overgreasing than
lack of lubricant. Always add grease sparingly.

To lubricate blower bearings, use the following procedure:
1. Shut down the machine.
2. Remove guards as necessary.
3. Inject the recommended grease using a grease gun. The
proper amount of grease will vary with bearing size.
4. Reinstall guards and restart blower.

Before installing, “butter” both sides of replacement bearings by
forcing grease into each side until it is flush with the race. For
outboard tandem bearing installation, follow procedures packed
with each new bearing set.

Gear-type couplings must contain lubricant at all times. They
are lubricated at the factory with Texaco Code 1912 coupling
grease and should be relubricated with identical or compatible
grease every six months.
Two coupling lubrication ports are located 180° apart. Remove
the setscrew lube plugs from both ports. Install a grease fitting
in one port and rotate the coupling until the grease fitting is
angled upward 45°. Pump grease in until clean grease flows out
of the opposite port. Remove the grease fitting, wipe off excess
grease, then replace and tighten the lube plugs.

Gear-type couplings generally require application of heat and
use of a puller to remove.

Refer to the appropriate blower diagram in this manual for
replacement part names and numbers. When ordering parts,
provide full information about your Spencer equipment. Be sure
when reading nameplates that you obtain the correct information
and record it on the cover of this manual for reference when
ordering parts.
Remember, the more complete your information, the quicker your
order will be processed. Incomplete information will result in
unnecessary delays and expense through callbacks. When in
doubt, consult the Spencer Parts Department for further infor-
mation.
When ordering parts, furnish the following:
• Serial number and model number.
• Motor horsepower.
• Blower housing diameter.
• Part nomenclature—refer to the applicable diagram and
locate the needed item by its number and name.
• (When ordering impellers and deflectors) Letter designation
for the specific components, obtained from the diagram.
• Form number of this manual—AA15.

Spencer provides prompt, courteous factory and field service
for all its machines. To determine the nature of the disorder and
the best way to correct it, service personnel will be dispatched
to your location. We typically request a Purchase Order prior to
sending service personnel; however we will proceed on verbal
orders in an emergency.
Once a full evaluation of the equipment has been performed by
our service personnel, you will be advised if the service work is
covered by the Spencer warranty. For out-of-warranty services,
please note that we accept Visa and MasterCard charges as
well as other forms of payment.
NOTE: Spencer products returned to the factory must be sent
freight prepaid and accompanied by a Return Service Order
(RSO) issued by the Spencer Service Department after we
receive your Purchase Order. Service costs will be quoted after
inspection and the work will be performed upon written accep-
tance of the quotation.

Spencer is committed to ensuring the safety of its employees. If
Spencer equipment has been exposed to potentially hazardous
contaminants or if Spencer service personnel could be exposed
to a potentially hazardous field environment, a Material Safety
Data Sheet (MSDS) is required (a) prior to dispatching Spencer
service personnel or (b) before receipt of any equipment for
factory service. If special precautions are necessary to work on
the equipment, contact the Spencer Service Manager.
