It is poss ible to assemble this pump for opposite
hand rotation, and care should be taken upon reassembly,
to check the rotation. In this particular
installation, the rotation is as indicated by the
arrow on the A-end. It should be noted that there
are arrows on both bushings and the rotor, and when
properly assembled, all three of these arrows will
point in the direction of the desired rotation. The
vanes are assembled with" the chamfer on the trailing
edge.
When replacing pump head 220648-8, care should be
taken to tighten screws that are diametrically opposi
te. It is good practice to turn the shaft while
these screws are being tightened to insure that the
rotor is not binding.
60. Reassemb ly. - It is essential before reassembly that
all parts are carefully washed in a non-acid cleaning fluid
to insure absolute cleanliness.
Care should also be exercised upon reassembly not to injure
oil seals.
