If the crankshaft shows diametrical wear in the area of contact with the lip seal, in order
to prevent the grinding operation, it is possible to reposition the ring in abutment with
the cover as shown in Fig. 8.

2.1.2 Assembly of mechanical parts
After having checked that the casing is clean, proceed with assembly of the mechanical part as described
below:
-
Insert the piston / con-rod guide units into the pump crankcase.
To facilitate pump shaft insertion (without the tab), it is essential to repeat the operation performed during dis-
assembly, pushing the piston/con-rod guide units as far down as possible (par. 2.1.1).
-
Before assembling the side cover on the PTO side, check the conditions of the radial ring lip
seal and relative contact area on the shaft.
If replacement is necessary, position the new ring using a tool (code 27904500) as shown in Fig. 8.
Before assembling the side covers, make sure there are O-rings on both of them and shim rings on the indi-
cator side cover only.
To facilitate filling of the first section and relative fitting of the covers on the crankcase, it is recommended to
use 3 partially-threaded M6 x 40 screws, (Fig. 8/a) to then complete the operation with the screws supplied
(M6x16).

Couple the con-rod caps to their shanks (Fig. 9, pos. 1).
Note the correct assembly direction of the caps.
