Pivot shaft (7) connects the main frame (1) with the track roller frames (3).
The pivot shaft extends through the main frame in order to connect the track roller frames at the rear of the tractor. Two sleeve bearings (2) in the main frame support the tractor on the pivot shaft. The pivot shaft cavity in the main frame is filled with oil, in order to lubricate the pivot sleeve bearings.
The pivot shaft is supported by the track roller frames on bearings (4). The track roller frames are filled with oil which lubricates the pivot shaft bearings. Plate (5) and bolts (6) retain the track roller frames on the pivot shaft.
Seal (8) contains the oil for the pivot shaft cavity.
