Compressor Vanes

 

1.  Using a 9/64 inch Allen wrench, carefully remove the air compressor cover plate and 

carbon gasket. 

2.  Inspect the carbon gasket for wear—reverse if worn or replace as necessary. 
3.  Spin the squirrel cage using a screwdriver. 
4.  If the vanes do not move in their slots as the rotor turns, clean the vanes. Clean the 

vanes and compressor body using Gast compressor cleaning fluid or suitable 
equivalent. Note: Do not use petroleum solvents, such as engine degreasers. These 
fluids leave unwanted residues behind that may cause the vanes to stick and/or bind. If 
the vanes are worn out, you may purchase a vane replacement kit (PN 10013106). 

5.   Reassemble the air compressor. Be careful not to over-tighten the cover plate. 

 

C. Cleaning 

 Wear Safety Glasses. 

1.  Disconnect the fitting at the air compressor outlet. 
2.  Disconnect the preheater outlet tubing from the solenoid valve and run into a bucket to 

catch the oil. 

3.  Jump the primary control T-terminals, then F-terminals to operate the burner.  
4.  Feed several drops of the Gast compressor cleaning fluid into the air compressor inlet 

and catch the spray at the outlet using a shop towel. 

5.  Allow the burner to run 3-4 minutes to flush out all the fluid from the air compressor, 

then remove the jumpers. 

6.  Replace the air compressor filter, reconnect the outlet tubing. 
7.  Reconnect the preheater outlet tubing.
