SYNTHETIC LUBRICANTS
Synthetic lubricants offer advantages such as extended service life, a broader operational temperature range,
reduced friction, and the ability to maintain a higher film strength, which can extend the service life of the gear
drive. For general operating conditions, AGMA lubricant number and corresponding ISO Grade should be as shown
in above table "Recommended Synthetic Lubricants". Synthetic lubricants can be made of various base stocks
which are incompatible with certain gear drive components; therefore,
any synthetic lubricant not listed in this
manual should not be used without first consulting Baltimore Aircoil International nv.
CHANGE INTERVAL
The original oil should be replaced after 500 hours or four weeks of operation, whichever comes first. After that, the
interval is 2500 hours or 6 months. It is recommended that the oil be drained through the drain plug when it is at
operating temperature. Refill the drive through the air breather port with the recommended type and amount of
lubricant as described in the above tables. See figure "Single reduction gear drive" for locations of the gear drive
fittings.
MAINTENANCE
Check oil level weekly with the unit idle. Add oil if level is below oil level indicator. Normal operating oil capacity of
each gear drive is given in the following table. Specific gear model number for each unit can be found in one of the
following tables or on the gear drive nameplate.
