1 With a proper mandrel, seat the main shaft taper roller bearing hitting securely on the bearing cover, while the main shaft is turned.
Turn the main shaft to both sides.
2 Measure with a depth caliper ruler the measurement (A) between the gearbox sealing surface and the main shaft bearing cover.
Measure the measurement (A) in two opposite points and determine the average value.

Gearbox 712.365/453/454/455
3.1 Measure with a depth caliper ruler the separation surface to the main shaft bearing cover support surface Measurement (B). Add this value to the oil deflector thickness
Measure the measurement (B) in two opposite points and determine the average value.
4.1 Measurement (A) - Measurement (B) = Measurement of the compensating washer.

Gearbox 712.360/361/362
3.2 Measure with a depth caliper ruler the main shaft flange front part to the collar Measurement (B).
Measure the measurement (B) in two opposite points and determine the average value.
4.2 Measurement (A) - Measurement (B) = Measurement of the compensating washer.
Determined the value, add from 0.02 to 0.09 mm to obtained the value for the compensating washer thickness. In versions with aluminum housing, the bearing adjustment must be performed through the preload.
