Use
-
Pump drives with clutch “BD” or “BDS”
The clutch must be engaged only with the engine idling or, however, not more tjem
1000 rpm.
The engagement must be quickly effected.
The same recommendations must be applied for disengagement.
Maintenance
-
Pump drives are supplied without oil.
Before their start up fill them up to the maximum level indicated by the oil dipstick.
-
Use oil for gears with EP additives, minimum viscosity index 95
Oil type can be choosen, depending on the ambient temperature, on Table A.
-
Effect the first oil replacement after 50 working hours; next ones each 1000 working
hours (or, the longest, every 12 months).
-
Periodically check the oil level.
-
Ensure that the oil temperature, when working, is not higher than 105 °C.
-
For clutches lubrication use lithium grease with consistency NLGI-2.
Lubrication points, referred to Fig. 5-6-7, are the following:
a) Cross shaft (A25, Fig. 5): lubricate each 300 hours.
b) Drive sleeve (A11, Fig. 5): lubricate each 300 hours on clutches “BD 145”,
“BD 290”, “BDS 145”, “BDS 290”. On the clutches the grease nipple (A11) is
located on the drive sleeve (A10) and is possible to be accessed only by
taking the inspection cover (A19) off. On clutches “BD 2200”, “BD 3300”: the
grease nipple (A11) is located on the outside of the housing (A16) and
greasing is required each 100 working hours.
c) Control levers (A43) (only on “BD 2200”, “BD 3300”, “BDS 3300”): lubricate
every 600 working hours.
d) Input shaft bearings for “BDS 2200”, “BDS 3300”, (C12, Fig. 7): lubricate
each 100 working hours; the grease nipple is on the outside of the housing
(C11, Fig. 7).
-
Clutch adjustment (pump drives “AM…BD…”, “AM…BDS…”).
A correct adjustment of the clutch is of fundamental importance to obtain a satisfactory
duration of the same and it is the responsibility of the operator to check it periodically.
The clutch adjustment (or checking) must only be effected with the engine stopped.
Referring to Fig. 1, Fig. 5: take the inspection cover (A19) of and, with the clutch
engaged, measure the distance A (Fig. 1) using a thickness gauge. If such a distance
is more than 1.3 mm it is necessary to adjust the clutch, by resetting distance A to 0.5 -
0.7 mm in the following way: disengage the clutch by pressing the lever (A13) opposite
to the engine, using a screwdriver move back the pin (A36), rotate the adjustment
device (A34) clockwise, striking it with a hammer and a soft metal rod, for a number of
lock grooves sufficient to reset the correct adjustment of the clutch.
Spare parts
When ordering spare parts specify pump drive model, ratio, serial number, reference
number indicated on the exploded view and desired quantity.
