The adjustment is necessary whenever the output flange is being replaced. This creates the preload on the tapered roller bearing for the shaft bevel gear.

Bevel Box "0AV":

• Remove the output flange and remove the bearing inner race/tapered roller bearing from the output flange.

Bevel Box "0CN":

• Remove the output flange and remove the bearing inner race/tapered roller bearing from the output flange.

Continuation for All

• Measure the length of the shaft on the old and new output flange to get the difference.

If the new output flange is longer- install a thinner shim.

Allocation. Refer to the Parts Catalog.

• Install the output flange.

Bevel Box "0CN":

• Install the output flange.

Continuation for All

Note

To remove the right flange shaft, use the Puller - Flanged Shaft -T10037- to avoid damaging the bearing on flange shaft.

• The depressions -arrows- must be under the bearing.
• Attach both halves to each other.

• Pry the locking ring -A- out of the needle bearing.

• So that the bearing contact surface on the shaft is not damaged, the shaft must be rotated during the pressing procedure -arrow-.
• Remove the seal -A- from the groove -arrow-.

Installing

• Coat the seal -A- with transmission fluid.
• Install the seal -A- into the groove -arrow- in the flange shaft.

Do not twist the seal.

• Install the Bearing Installer - Needle Bearing -T10047- ⇒ Fig. N39-10212.
• Press the flange shaft into the bearing.

• So that the bearing contact surface on the shaft is not damaged, the shaft must be rotated during the pressing procedure -arrow-.
