#81170 Bearing Blaster
Assembly of the #81170 Bearing Blaster:
Your new Bearing Blaster has three pieces; a base, base cap, and a pressure
ring. The pressure ring and the base cap are connected together in this package and
must be separated from the sprue using an X-acto knife or plastic clippers. Once
separated, press the base cap onto the center of the base (see diagram). It should fit
snugly and once installed, should not need to be removed. The bearing to be cleaned
will nest itself between the pressure ring and the base cap (see diagram on back).
(Please Read This Section Carefully!) Bearing information and precautions:
When using the #81170 Bearing Blaster, always wear safety glasses and
protective hand gear such as latex or vinyl gloves and follow all precautions on the
can of cleaner (or lubricant). Use cleaning sprays, solvents, and/or lubricants only in a
well-ventilated area and away from fire or flames. RPM R/C Products cannot be held
liable for failure to follow all safety precautions listed here and on any other products
used in conjunction with the Bearing Blaster, nor may RPM be held liable for the
intentional misuse of this product.
The #81170 Bearing Blaster is extremely effective on all open bearings and on
most shielded bearings. Consult the manufacturer of your sealed bearings before
attempting to use the RPM Bearing Blaster on them. If you are not sure what type of
bearings you have, consult your local hobby shop before using the Bearing Blaster.
RPM recommends using motor spray or electrical contact cleaner to clean
your bearings. Lubrication is of personal preference. Consult your hobby shop for
information regarding the types of bearing cleaners & lubricants available.
Using the #81170 Bearing Blaster:
The Bearing Blaster is designed to allow all waste products and debris to exit
the bearing and the Bearing Blaster through the large openings in the bottom of the
base. This prevents backpressure in the tool as well as preventing debris from re-
entering the bearings. Because of this flow through design, the Bearing Blaster must
be set on a rag or several paper towels to absorb excess cleaner (or lubricant). When
finished, these rags or paper towels must be disposed of in accordance with all state
and local laws.
Place the bearing to be cleaned on top of the base cap (See diagram). Place
the pressure ring over the bearing. Using the extension tube supplied with your
cleaner, slide the tube into the small hole at the top of the pressure ring. Push it in until
it locks in place. With the other hand, press down firmly on the pressure ring. This is to
force the cleaner through the bearing and to prevent the pressure of the cleaner blast
from flowing around the bearing. Spray a short burst of cleaner through the Bearing
Blaster, rotating the pressure ring back and forth as you spray to help dislodge debris
trapped between the bearing balls and the bearing races. Remove the bearing from
the Bearing Blaster and spin it between your fingers. You will be able to feel if there is
any grit still in the bearing. If there is, repeat the procedure until the gritty feel is
completely eliminated.
Set your bearings aside until they dry. Once dried, repeat the above
procedures using a bearing lubricant. This will force lubricant throughout the bearing,
consequently, dramatically extending the life of your bearings! Using the Bearing
Blaster at regular intervals will dramatically improve bearing life and performance,
which will result in a smoother, faster vehicle as well!
