12.3 MECHANICAL REASSEMBLY PROCEDURE
1.
The bearing must be inserted separately with the inner bearing fitted first, and pulled down with
the bearing tool, onto the shoulder in the bearing housing.
IMPORTANT:
There must be no gap between the bearing outer race and the shoulder of the
aluminium extrusion. Remove the insertion tool at this point and check that the inner bearing is
fully home.
Fit the bearing spacer and press in the outer bearing using the bearing tool. Check the spacer has no
end float but has slight sideways movement to allow for shaft insertion.
Note:
The outer bearing will be protruding out of the housing by approximately 1/8 “ (3mm).
Refer diagram.
2.
Ease the shaft through the bearings from inside the tub. Take care the shaft is fitted with the
threaded retaining nut section facing downward in the direction of the base.
3.
Fit the shaft retention nut. Use the spline tool and spanner to tighten the shaft retention nut.
4.
Invert the tub. Take care not to damage the shaft or flooring.
Fit the assembly thimble sleeve
onto the shaft before fitting the seal.
Lubricate the seal outside diameter with liquid detergent
and then slide into position by pressing down on both sides of the seal.
Note:
The seal should be flush with the lip on the base of the tub.
