• Lubricate with oil the new vanes before inserting them inside each
groove of the rotor.
• Reinstall all components in the following order: rear flange, seal
ring, bearing, compensation ring, gasket and flange with lubricating
pump (we recommend the pivot-key be correctly fitted onto the shaft
groove).
Fig. 6.4
Do not damage components during assembly by
forcing them exceedingly.
• Do not flip the seal ring during
rotation of the shaft. Do not leave
foreign objects inside the pump.
Adjusting the self-lubricating pump
• The automatic lubricating pump is adjusted by the manufacturer
before the shipping.
• If consumption noticeably differs from the indicated value, adjust it
as follows:
-
Remove the upper protection cover;
-
Using a screwdriver and a 10 mm wrench, adjust the adjusting
screw (K). Close the nut and remount the upper protection cover;
-
It is advisable to turn the screw of ¼ of turn and verify the actual
consumption.
Fig. 6.5
Do not reduce oil consumption below the value
indicated in par. 2.4 (for functioning at speeds
different from the maximum, flow is proportionate
to rotating speed).
• ½ turn of the adjusting screw causes a variation in the flow of
appr.
40 - 80 g/h
, depending on using conditions.
Replacing gearbox components
• The pump with a 540 rpm gear box can be transformed into a
pump with a 1000 rpm gear box (and vice versa):
-
Take down the gearbox as illustrated. Remove also the drive
shaft’s pinion;
-
Install the new pinion closing the nut;
-
Mount the gear wheel including bearings and seals on the front
cover, properly aligning components. This housing may now be
installed in the gear box: fit the bearing in the internal housing on
the flange;
-
Properly engage gears, replace the cover’s gaskets to complete
gear replacement. Insert the parallel pin, which maintains the
correct alignment.
See Fig. 6.6.
