GPA20 shiftable shaft
H . Shaft with reinforced sealing
Construction
(Fig.
14)
The output shaft (13) receives drive from the upper line
of the power take-off and, via the different engaged
pinions, transmits it to the implement that needs to be
driven.
At the front, it is supported by a straight roller bearing
force fitted into the centre housing and at the rear by
two taper roller bearings (1) (2) and (3) (4) installed
opposite one another.
Taper roller bearing clearance is obtained via shim(s)
(6) placed between the rear bearing cup (4) and the
seal holder (8).
As with the other PTO versions, it supports the 540
and 1000 rpm driven pinions.
When operating in rice fields or in particularly damp
farming conditions, the rear bearing seal is reinforced
by a "cassette" seal (11).
