The following measuring procedures describe the required steps to calculate the thickness of the compensation washer when the retarder assembly measurement information is not available. The assembly measurement information is supplied when the retarder is inspected by a Voith representative.
1 Put the outside race of the bearing (4) on the taper roller bearing (3) of the retarder input shaft.

The measuring device (8) must be obtained from a Voith Turbo representative who will provide, inclusive, the specific training for its operation.
2 Place the measuring device (8) on the retarder input shaft resting on the flange of the housing (2).
Do not move the bolts (7) of the measuring device (8), as this compromises the values obtained in the measuring and may result in retarder or gearbox damage.
3 Install the bolts (6) and tighten them to 10 Nm torque.
Utilize four M10 x 40 mm bolts.
4 Manually, turn the gear (5) fifteen turns clockwise and fifteen turns counterclockwise.

All measuring is to be carried out at room temperature.
5 With a digital depth gage (9), determine the dimension "C" and take note.
Dimension "C" = measured from the top edge of the measuring device (8) to its measuring plate.
Measure with the input shaft in vertical position.

6 Read the dimension "H" (arrow) on the measuring device (8).
7 Calculate the dimension "B" and take note.
Dimension "B" = dimension "H" - dimension "C".
8 Remove the measuring device(8).

9 Measure and take note of the dimension "A"
Dimension "A" = measured from the sealing surface of the gearbox (1) flange to the thrust surface of the gearbox (1) compensation washer.
10 Calculate the thickness (dimension "D") of the compensation washer and take note.
Dimension "D" = dimension "A" - dimension "B" - 0.02 mm.
The compensation washer thickness has to correspond to the calculated value. Should it be necessary, a maximum of two washers may be used to reach the calculated thickness.
Should it not be possible to reach the corresponding thickness with the utilization of two compensation washers, a 0.03 mm clearance is permissible.
In the utilization of two compensation washers, install first the washer of greater thickness in the gearbox case (1).
