ADJUSTING THE CIRCULATION VALVE
The Cargo Floor systems are already adjusted and tested when you take them over. In certain
circumstances (moved combination valve) it may be necessary to check the adjustment. You can do
this as follows:
Necessary tools:
2x spanner 17;
High viscosity oil;
Copper
grease;
Steel
brush.
Check that the wire rod is fastened securely to the switchover valve plunger (see figure 33). If not, then
screw the wire rod (1) as far as possible into the plunger and secure this with the contra nut (2)
(spanner size 17).
Loosen nuts 3 and 4 (spanner size 17) and move these about 3 cm in the direction of the switchover
valve. Now switch the pump on. The system will stop now at the point where the command lip no
longer operates the switchover valve. Switch off the pump.
Now push the wire rod 1 in until the spacer ring 2 touches the switchover valve.
Tighten nuts 3 and 4 so that the spring is fully tensioned, and secure them by tightening them against
one another. Repeat this procedure for the other side.
N.B. It is worthwhile spreading some copper grease on the wire rod 1.
