4. Clean the turbine and the turbine hub to remove
metal filings and any wettable powders.
5. Inspect the turbine blades for wear.
Note:
Hold the turbine in your hand and spin
it. It should spin freely with very little drag. If it
does not, replace it.
6. Assemble the flowmeter.
7. Use a low pressure (5 psi or 50 kPa) air jet to
ensure that the turbine spins freely.
Note:
If the turbine does not spin freely, loosen
the hex stud on the bottom of the turbine hub by
1/16 of a turn until it does spins freely.
