Powered front axle, description
Po wered front axle on 6100---8100 tractors is the same Sige---
axle as on Valmet ---05 series.
The powered front axle is attached to the front end of the trac-
tor by two bearing brackets. There is a small clearance be-
tween the axle housing and central pivot bearing brackets.
This clearance can be adjusted with shims.
The power is transmitted from the gearbox to the pinion shaft
by the propeller shaft. From the pinion shaft, power is trans-
mitted through the differential to the drive shafts and through
the double universal joints to the hub reduction gears and the
front wheels
The drive shafts are carried in bearing bushings in the axle
housing and in ball bearing in the swivel housings.
In each hub gear the planetary pinions (3 off) are carried in
roller bearings in the retainer. The ring gear is bolted to the
steering knuckle.
