Lower the bottom agitator shaft section into the vessel
Make that the holding point is above the center of gravity-harzard of overturning.
With motors: Attach an additional rope to the motor.
Position the two wooden beams on both sides of the shaft, insert the bolts and tighten the nuts so that there will begaps os appox. 1 cm between the shaft and the beams.
Checking the Agitator Shsaft Run-out
Provide access to the drive (e.g.coupling or fan wheel) sothat the the agitator can be rotated by hand.
Apply a dial-indicator to the end of the agitator shaft.
Fully rotate the agitator shaft by hand(e.g.by turning thefan wheel).
Measure the total indicated run-out X, read the length of the agitator shaft from the specification.
The total indicated Xmax run-out shall comply with the following condition : Xmax / Y < = 1/1000
i.e. per meter shaft length the total indicated run-out shall not exceed 1mm in other words : the deviation from the imaginary center line of an absoluty true shaft shall not exceed 0.5mm per meter shaft length
For rubberlined shafts : If possible, carry out the measurement on a turned surface, e.g. on the cap nut. When the measurement is being taken right on the rubberlined shaft the run-out limit may be increased by 1.5mm in order to compensate the uneveness of the rubberlining, particularly at the seam.
When the run-out exceeds the permissible value and there is a flanged coupling between the bearing shaft and the agitator shaft:Check that there are no foreign bodies between the coupling fiange halves If the T.I.R. stills exceeds the permitted value or the agitator comes without a flanged coupling but with a threaded coupling or integrated bearing agitator shaft instead:Contact the TAEWOO Service department(either the bearing shaft or the agitator shaft resp. the bearing agitator shaft suffered bending during transport or a fiange was damaged and must be trued).
Caution : Never work inside vessel without supervision.
