Place the spinner-cam system on the rear plate (4) and fix it with the clips (7).
Offset the spinner-cam (a) by pressing on the
blades.
Turn the shaft up to the maximum
displacement of the lever (b).
The distance between the seat (c) and the
stop valve (d) must be 0.9 to 1.2 mm (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.
In the rear plate (7), place the Oldham coupling (5), the vane (4) and the rotor (3).
Screw the seat (9) equipped with its O-ring (8). Place the piston (11) with its antisck-
back device (10), the spring (12), the cylinder (13) and the washer (14).
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.
Pump in a horizontal position, pour a small quantity of oil beforehand around the
exhaust valve holes.
Place the valves (2) or (11) equipped with the springs (3) or (12)
Place the valve covers (6) or (17) and fix them with screws and washers.
