Note:
Where high temperatures and/or a dirty
atmosphere exist more frequent changes may be
necessary. Periodically check to ensure the
correct level of oil is in the reducer. Too little oil
will cause accelerated wear on the gears. Too
much oil can cause overheating, seal deterioration
and leakage.
3.
Lubrication - The correct oil to use in your
reducer depends on the worm’s RPM, ambient
temperature and the severity of use. The
following chart can be referred to for reducers
with 1750 RPM worm speed, operating under
normal duty and with ambient temperatures
from 18°F to 125°F (-8°C to 52°C). See Fig. 2.

General - Inspect weekly to make sure reducer
remains securely bolted.
Bearings
1.
Lubrication - Greasing frequency should be
regulated to as many times as necessary to keep
a small film of grease leaking at the seals. This
will protect against foreign materials entering
the bearing. The following list is provided to aid
you in acquiring the correct (or an equivalent)
grease. See Fig. 3.

Note:
Do not over grease as this can cause blown
seals or overheating bearings.
2.
Replacement - If bearing replacement becomes
necessary, remember to clean off the shaft, file
smooth any grooves or set screw marks and oil
the shaft before slipping on the new bearing.
Note:
If the bearing does not slide easily onto the
shaft, use a soft metal bar or mallet to tap
against the inner race.
3.
General Maintenance - Set up a weekly check
on all bearings to ensure they remain tightly
bolted down, set screws remain fastened
securely and they are correctly lubricated.
Chain and Sprockets
1.
Lubrication - For long chain life a constant film
of oil is recommended. Use a good quality, non-
detergent, petroleum-based oil from the list
shown in Fig. 4.
