2. Adjust the Sankyo Compressor on the PA-28RT-201T as follows:
A. Rotate the compressor to obtain tension of 100 pounds for new belt or 85 to 90 pounds for old belt.
B. Run the engine for a 15 minute period at 1900 RPM with the compressor engaged.
—WARNING—
If the air conditioner is to be operated during ground servicing,
the test area should be clean and free of any loose objects lying
on the ramp. Only the service valve located on the evaporator
assembly should be used for testing.
C. Shutdown engine and recheck the belt tensions. New belt tension should fall back to desired
tension of 85 to 90 pounds. Old belts reinstalled should retain the 85 to 90 pounds span tension.
D. This tension check should be made at every 100 hours or annual inspection whichever occurs first.
