Section 3 Maintenance & Repair
before servicing unit
CAUTION
A Speed Reducer, like other types of machinery, needs to have regular maintenance if it is to perform properly, give lasting
(a) Clean and Inspect
Thoroughly clean all of the parts in a good grade of cleaning solvent; one that is not flammable, not toxic and will not
cause skin rashes. If necessary, use rubber gloves. Inspect all parts for wear, nicks, scratches and damage that would
render them unusable. If a part is questionable, it is better to replace it rather than take a chance on premature failure
when the Speed Reducer is placed back in service. Always replace O-rings and seals, and it is a good idea to use new
roll pins as well. Sometimes it is permissible to reuse bearings and bushings...it depends on how much use they have
had. The ball bearings should not exhibit any surface irregularities. If the ball bearings show any sign of spalling,
corrosion, discoloration, material displacement or abnormal wear, the bearings should be replaced. If the Speed Reducer
was disassembled only to replace damaged seals after a short period of service, it is not necessary to replace the
bearings.

Recommended Gear Oil:
•
The following guidelines should be used in the break in of Bloom Speed Reducers.
O-Rings, bearings, bushings and the rubber parts of seals with oil during assembly. Use a light coat of thread sealing
compound on pipe fittings and plugs.

.
OIL CAPACITY CHART
Speed Reducer Series
(c) Oil Level:
To check the oil level, remove the level plug. The oil should be level with the bottom of this opening. If more oil is
needed, use the recommended gear oil listed below.
Use Bloom ULLTRA-LUBE NO. 601 trans-worm gear oil; available from Bloom in pints or quarts. For emergency
situations when Bloom ULLTRA-LUBE NO. 601 is not immediately available, use Phillips 66 Company SAE grade 80W90
superior multi-purpose gear oil (Phillips 80W90 SMP) meeting API classification GL-5 or equivalent brand. Continuous
use of oil other than Bloom ULLTRA-LUBE NO. 601 or Phillips 80W90 SMP oil may shorten the life of the gears. DO
NOT mix Bloom #601 or Phillips 80W90 SMP with more than 50% of any other kind of oil.

Section 4 Speed Reducer Break In
• Speed Reducers, like any other kind of machinery, require a “break in” to perform well and
to maximize their life.
• Do not run the speed Reducer at high speeds when performing this operation.
• Do not exceed one half rated load for the first thirty minutes of operation. This will ensure
that the worm and gear have an opportunity to wear in properly.
CAUTION
• Periodically, check the gearbox for temperature rises and allow the Speed Reducer to cool
down if necessary.
For best results, only use Bloom replacement parts 800-394-1139
