Disassembly
Cleanliness is extremely important when repairing a steering
orbitrol. Work in a clean area. Use a wire brush to remove
foreign materials and debris from around exterior joints of the
unit.
1. Place the steering unit in the holding tool. Screw out the
screws in the end cover (6 standard plus one special
screw).
2. Remove the end cover.
3. Lift the gearwheel set (with spacer if fitted) off the unit.
Take out the two O-rings.
4. Remove cardan shaft (10, Figure 10-18).
5. Remove distributor plate (12).
6. Remove the threaded bushing (4) over the check valve.
7. Remove the O-ring (11).
8. Shake out the check valve ball and suction valve pins
and balls (Figure 10-21).
9. Take care to keep the cross pin in the sleeve and spool
horizontal. The pin can be seen through the open end of
the spool. Press the spool inwards and the sleeve, ring,
bearing races and needle bearing will be pushed out of
the housing together (Figure 10-22).
10. Take ring, bearing races and needle bearing from sleeve
and spool. The outer (thin) bearing race can sometimes
“stick” in the housing, therefore check that it has come
out (Figure 10-23).
11. Press out the cross pin. Use the special screw from the
end cover (Figure 10-24).
