Note! If the centring springs are changed, they must be fitted
as shown in figure above.
Note! Before removing the springs, mark position of the valve
spindles in ralation to each others e.g. with tusche. Rinse the
spindles with gas oil (also lubricating properties) so that they
can move easily and the centring springs can center them.
9. Fit the ring over the centring springs. Place the thrust bear-
ing assembly onto the valve slide.
Note! Thick thrust washer first, then bearing and then the thin
thrust washer. Chamfered side of the thick washer towards the
slide.
10. Push the valve slide into the housing fully home
Note! The valve slide together with the thrust bearing is easier
to fit into the housing when the steering valve is horizontally.
Turn the slides until the cross pin is parallel to the flat side of
the valve housing.
11. Fit a new o---ring and the distributor plate onto the housing
according to the mark. Fit the rotor shaft so that grooves on
it engage the cross pin.
