Instructions
3.1 Installation and Maintenance Recommendations
3.1.1 Installation
1.
Select a gearbox, which has a rated capacity greater than the input power
2. Gear units are shipped dry and are fitted with a warning label
3. Check your gear unit for damage during shipment
4. Take care when fitting couplings; a blow on a shaft end can cause gear overmeshing.
5. Shaft alignment is critical, check on installation
3.1.2 Oil
Levels
The information given below assumes that the gear unit is positioned with all shafts in a
horizontal plane.
For input speeds up to 1500 RPM the oil level in the gear unit should be maintained just
below the centerline of the shafts. A sight glass or level plug is provided for level indication.
A change of oil may be required for speeds of 1500 RPM or above, and Neeter Drive should
be consulted.
For input speeds of 250 RPM or below grease lubrication should be used.
Important
Neeter Drive should be advised when a gear unit is installed with a shaft
positioned vertically.
3.1.3 Case
Temperature
Bevel gear units will operate with a maximum case temperature of 80°C. If this temperature
is exceeded Neeter Drive should be consulted.
3.1.4 Maintenance
Instructions
A new gear unit should be drained after 100 hours of operation and cleaned using a light
flushing oil. After this the gear unit oil should be changed every six months or 2500
operating hours. Where severe operating conditions are encountered more frequent oil
changes are advised.
The gear unit should be warm when an oil change is undertaken. Check oil levels regularly.
Warning:
The case temperature must not exceed 80°C (see case temperature)
