DT 46476 (DW260-080) Axial Play, Input Shaft Measuring Clamp

Adjustment Procedure


    Object Number: 1256054  Size: SH

    Important: Incorrect axial play may cause the vibration noise. The specification of the axial play is 0.18-0.42 mm (0.0007-0.0165 in).

  1. Clamp DT 46476 on the input shaft so that the measuring base rests on the stator shaft.
  2. Set the dial gage to 0.
  3. Measure the axial play by pulling and pressing on the handle. Repeat the measurement.
  4. Calculate the measurement values.
  5. Average Example:

    M1 = 0.51 mm

    M2 = 0.49 mm

    M = (0.51 + 0.49)/2 = 0.5 mm

    S specification = 0.18-0.42 mm

    D adjustment value = 0.5 mm--(0.18-0.42 mm)

    So, D is 0.08-0.32 mm.

    Calculate the average, so D is 0.2 mm.

    Important: The disc thickness must be between 0.08 mm (0.003 in) and 0.32 mm (0.013 in) thicker. It is sensible to select one with a disc that averages 0.5 mm (0.008 in) thicker than the one that was installed.

  6. Replace the shim.
