1. Prepare the shaft:
a) Polish off any flaws with a fine emery cloth.
The end of the shaft must be clean and free from burrs.
b) Coat the inner conic, the outer cylindrical surfaces, and the thread of the conical
sleeve with a thin layer of grease.
The proper lubrication is grease for bearings, for example Exxon Mobil Unirex N3,
Mobil Mobilith SHC 220 or equivalent.
NOTICE:
Surplus grease can cause the impeller to become loose. Remove surplus grease
from conical and/or cylindrical surfaces of shafts and/or sleeves.
