Inlet Guide Vane Assembly Drive Screw Lubrication<br />
<strong>The</strong> inlet guide vane assembly drive screw requires lubrication about every 6 months or as required. Be<br />
sure to use only recommended high quality, synthetic grease when performing this procedure. (Refer to<br />
Section Two, <strong>Compressor</strong> Specifications, for complete information about lubricants.)<br />
1. Unscrew the cover tube at the motor bracket.<br />
2. Carefully pull away the cover tube, just enough to expose the drive screw.<br />
3. Using a clean cloth, wipe off all the old grease from the drive screw surface.<br />
4. Work fresh grease into the drive screw by hand, being sure to use sufficient grease to cover all<br />
surfaces thoroughly.<br />
5—14<br />
WARNING:<br />
Use only the recommended high quality, synthetic grease for this procedure. Under<br />
certain conditions, other products may contribute to mechanism malfunction.<br />
5. After greasing is complete, replace the cover tube and screw it back to the original position.<br />
Bypass Valve Lubrication (if applicable)<br />
Some TA <strong>3000</strong> compressors utilize two different types of bypass valves, depending on the rating of the<br />
compressor. To correctly determine the type of valve used in a particular installation, refer to Figures 5—<br />
1 and 5—2, which illustrate the two types of valves.<br />
<strong>Turbo</strong> Air <strong>3000</strong> <strong>Compressor</strong>s rated up to and including 600 horsepower utilize a box-shaped bypass<br />
valve which requires periodic lubrication. <strong>The</strong> larger cylindrical, angled valve employed on higher rated<br />
machines (700 horsepower and larger) does not require lubrication. Both of these valves characteristically<br />
operate either in a fully opened or fully closed position. Every 6 months (or as required), it is<br />
necessary to lubricate the piston’s seals and guide rings of the smaller, box-shaped valve. Since other<br />
products do not provide the required level of protection and could gum up under service, use only the<br />
recommended lubricant. (Refer to Section 2, Specifications, and Section 7, Parts and Service, for full<br />
ordering information.)
