IMPELLER
Removing & Refitting
In order to remove the impeller, take off the volute body as in Chapter 3. Undo the impeller
nut and remove the impeller from the splined shaft, carefully levering between the impeller
and the pump head if necessary.
When refitting the impeller, use a new split pin to secure the slotted nut. There is a hole
through the shaft to receive the split pin.

(8.05”) or if ‘B2’ is less than 203.2mm (8.00”), fit a replacement impeller.
