• Rest the frame on a flat surface in order to raise the pump.
• All surfaces in contact are coated with oil.
• Observe a nominal clamping torque of 0.8 mdaN (5.8 ftlbs) for the
reassembly of the functional block.
The functional block is reassembled in the reverse order of disassembly.
On the median flange, check that the lubrication hole is not
blocked.
New vanes are assembled on the rotors, with the rounded
edges facing outwards.
Pour a small quantity of oil beforehand around the exhaust valve holes. Position
the exhaust valves, the springs and the exhaust valve covers.
This is performed after the reassembly of the functional block, before fastening
the nuts. Fit a new seal on the tube and connect the assembly to the frame.
Position the tube attachment on the pin and tighten the nut on the rear flange
(maximum clamping torque 0.8 mdaN (5.8 ft lbs)).
In the sleeve, fit the ball and the spring and fasten the connector. Then fasten
the assembly on the side of the frame.
SD series pump (except 1015 SD, 1021 SD):
Offset the spinner-cam (1) by pressing on
the blades.
Turn the shaft up to the maximum
displacement of the lever (2).
The distance between the seat (3) and
the stop valve (4) must be 0.9 to 1.2mm
(0.035 to 0.047 inch) :
it is set by adjusting the orientation of the lever.
The stop valve face must be perpendicular to the axis of the oil inlet hole; when
free, the stop valve should rest on its seat: check the parallelism of the lever in
relation to the bearing face of the stop valve seat. Orient the seat to obtain the
correct setting.
I, C1, C2 series pump (also 1015 SD, 1021 SD):
Position the rotor of the oil pump so that the slot is horizontal (or parallel with the
pump base). To turn it, use the fan. Do not forget the Oldham coupling.
