The new bearings can be mounted cold with a press or rocker, supporting it on the lateral surface of the
ring nuts involved in press fitting with the rings. The press fitting operation can be facilitated by heating the
involved parts to a temperature between 250 o -300 o (F) 120 o -300 o (C), ensuring that the ring nuts go down to
end stroke in their housings.
Never exchange the parts of the two bearings.
The shim pack must be redefined as follows:
Insert the bend shaft in the casing, checking that the PTO shank comes out from the provided side. Fasten
the PTO side flange to the casing, taking care to set the lip seal as indicated in point 2.1.2. Bring the indicator
side flange closer as in point 2.1.2, fig 9, with the help of a thickness gauge (see fig. 15).

A) Disassembly/Reassembly of the bend shaft without bearings replacement
After having removed the side covers as indicated in point 2.1.1, remove the outer ring nut of the bearings
from the relative covers and the inner ring nut with the remaining part of the bearing from the two ends of the
shaft by means of a normal “pin punch” or a similar tool as indicated in fig. 13 and 14).
