2. Determine dimension "f"
Use a depth gauge to measure the depth of
the bearing opening in the tensioning plate.
For example: 8.56 mm

1. Determe dimension "d".
d = dl + d2
determine dl
To do this, measure with a depth gauge from
the flat housing surface onto the measuring
mandrel (as in measurement of "Cl ").
For example: 119.00 mm
d2 = Measuring mandrel radius
