Note
If the pressing force is outside the given
range or if the pinion "jumps" in bit by bit,
it must be dismounted, checked and oiled
before it is fitted again!
Press the pinion onto the new motor.
Check the pressing force!
For an axis with diameter of 15.5 mm use:
• minimum pressing force = 18.5 kN
• maximum pressing force = 39.5 kN.

For article number see:
• Required equipment - tools etc. on
page 371
Measure the distance between the motor
flange and the outer surface of the pinion
with the measuring tool.

For article number see:
• Required parts on page 371
Modify the distance with shims to obtain the
same distance as measured when dismount-
ing the old motor (+0-0.05 mm)

How to fit the pinion is described in:
• Refitting the pinion on motor axis
5 on page 375
Note
The pinion of motor axis 5 is matched with
the bevel gear for axis 5. When fitting a new
motor the pinion from the old must be fitted
on the new motor!
