The driven pinions (5) (6) are fitted on the PTO shaft
located on the lower part of the axle housing. These
pinions are constantly meshed with the double driving
pinion driven by the top shaft line whose speed is
transmitted by the PTO clutch.
The PTO shaft (10) is fitted, at the front, on a roller
bearing (1) force-fitted in the axle housing, and at the
rear, on a hub (9) rotating on a roller bearing (15).
The 540 rpm version has 6 splines, and the 1000 rpm
version has 21 splines.
In the 540 rpm configuration, the shaft (10) is integral
with the pinion (5) via splines. The pinion (6) and ring
(4) assembly rotate freely on the shaft (10).
In the 1000 rpm configuration, the shaft is splined to
the pinion (6). The pinion (5) and ring (3) assembly
