Insert the internal ring (pos. , Fig. 61) and external ring
(pos. , Fig. 62) of a bearing from one side of the pump only.
Pre-assemble the left and right PTO bearing covers:
Insert the radial seal ring into the PTO bearing cover using the
tool code 27539500 (pos. , Fig. 63).
Before proceeding with the assembly of the radial seal ring,
verify the condition of the seal lip. If it is necessary to replace
it, position the new ring as shown in Fig. 64.
If the PTO shaft shows diameter wear
corresponding to the seal lip, then to avoid
grinding you can position the ring as a second
step as shown in Fig. 64.
