4.4 Assembly
1. Install any new parts.
2. Guide the rotor and bearing assembly onto the shaft.
Make sure the rotor is installed with the cup side of the
Pelton wheel facing the “IN” side of the housing.
3. Place a new gasket on the insert. Always use a new
gasket.
4. Place the shaft assembly insert, gasket, and rotor
assembly back into housing by inverting the housing to
keep gasket and rotor assembly in place.
5. Install the threaded plug and tighten to 50 ft-lb.
4.5 Pickup Coil Testing
Testing the MAG and MCP (RF) coils consists of measuring the
resistance with an ohmmeter. Resistance measurements are to be
made when there is no flow through the meter or with the coil
removed from the meter housing.
1. Measure the resistance between pin A and pin B. The
resistance should be approximately as listed in the
following table of some common coils.
2. The resistance from any pin to the case should be greater
than 1 Mohm.
