13. Inspect the IGV Housing assembly for residue/contamination or foreign objects.
14. Remove the small lower worm gear bearing from the housing. Perform this step by pushing the
bearing out from the port below the bearing. Refer to Figure 4-62 Small Worm Gear Bearing.
Figure 4-62 Small Worm Gear Bearing
4.9.3.3 IGV Assembly Installation
• • • CAUTION • • •
Fitting incorrect IGV components for the specific compressor model will result in physical damage to the compressor.
1. Ensure that all components and threads are clear, clean, and oil free.
2. Install the lower (small) worm gear bearing into the housing. This may require a very light tap with a
hammer. Ensure the lower worm gear bearing is fully seated into the housing. Refer to Figure 4-62
Small Worm Gear Bearing.
3. Ensure the IGV position indicator magnet is in place in the IGV Throat assembly. Refer to Figure 4-63
IGV Position Indicator Magnet.
Figure 4-63 IGV Position Indicator Magnet
4. Place the IGV Throat assembly into the IGV Housing orientating the IGV Throat threads directly below
the IGV Motor Mount.
5. Add one (1) drop of threadlocker (Loctite 243 blue or equivalent) to the IGV Throat fastener threads
and install. Torque to 5 Nm (44 in.lb.).
6. Rotate the outer ring of the drive assembly and ensure that the guide vanes move freely. The assembly
must rotate over a span where the vanes are open (perpendicular to gas flow) and fully closed.
7. Fit the upper (large) bearing to the worm gear and install the snap ring. Refer to Figure 4-60 Large
