2.1.7.
Turbine runner/rotor mounting
The wet side rotor, or "runner" is fitted to the bottom "wet
end" of the shaft. Take care that the runner is the right way
around to spin clockwise as shown below.
Fit the shim washers first. The height of the runner is
factory set using the correct number of shim washers. If you
remove the runner then take care to keep these washers
and refit them exactly as supplied.
The turgo runner itself is clamped to the shaft using two
"taper caps" behind and in front. The large nut slips loosely over the shaft, and the smaller
nut thereby applies pressure to the taper cup clamping arrangement.
Tighten the nut to 50 Nm torque or "very tight". The runner may be
damaged if it slips.
(50Nm/37ftlb is the same as 25kg weight at the end of a 20cm long
spanner or wrench.)
