Re-install the 2 end shaft screws with the
end shaft plates, on both retarder sides.
Don’t install lock tabs yet.
Apply a tightening torque value of 30 Nm (+/-
20%)
(22 lb-ft±20%)
alternately on these 2 screws,
and 2 times.
Use a 17mm socket and a bar to lock the rotation of
the rotor.
Check the run out of the rotors by using a
magnetic dial gauge and a sensor.
Maximum value allowed is 0.28 mm.
Nota: In case the maximum value is up to
0.28mm, contact TELMA technical
department.
Measure air gaps by using a feeler gauge.
Don’t turn the rotors and measure the air gap
between the rotor and each pole shoe.
The average of these 8 values has to be:
0.80 mm (0 / -0.15 mm) (0.026”-0.031”) for
AF50-60 and LVRS600
1.00 mm (0 / -0.15mm) (0.033”-0.039”) for
AF50-55.
Proceed on the same way for the both retarder
sides.
Adjust air gap by adding or removing air gap
adjusting shims if the value is not correct
(operations 6A to 6G).
For additional information related to air gap
measurement, please refer to technical
information
