7. Then lower the adjustment ring on the
frame. When the adjustment ring is properly
seated, the clay or putty will compress,
showing the exact amount of clearance
between the adjustment ring and the main
frame.
8. Lift the adjustment ring from the frame and
measure the thickness of the clay or putty
balls.
a. If the clay ball thicknesses are less than
1.6 mm (0.0625") the minimum distance
shown in Figure 3-9, then the adjustment
ring fulcrum surface is to be machined to
obtain the minimum clearance. Refer to
the example above.
b. If the clay ball thicknesses are more than
5 mm (0.196"), the maximum distance
shown in Figure 3-9, then the adjustment
ring fulcrum surface is to be built up
with weld and machined to obtain at
least the maximum clearance. If weld
build up is required, then contact Metso
Minerals for weld and machining
procedures.

For this procedure refer to Figure 3-13.
1. Remove worn bronze main frame seat liner
and fulcrum bar segments.
2. The replacement main frame seat liner and
fulcrum bar will be shipped in segments.
3. Position the seat liner at the dimension
shown and weld using 4 mm (0.16") weld
rod which meets AWS E Cu AL-A2 or R Cu
AL-A2 specification. Do not butt vertical
joints.
4. When using these 4 mm (0.16") weld rods
reverse polarity and use between 130 to 190
amps. The main frame seat and seat liner
must be preheated to 20°C (68°F) to 40°C
(105°F).
5. Weld the fulcrum bar as shown.
6. After welding a new seat liner and fulcrum
bar to the main frame place balls of clay or
putty around the top outside corner of the
main frame flange.
7. Then lower the adjustment ring on the
frame. When the adjustment ring is properly
seated, the clay or putty will compress,
showing the exact amount of clearance
between the adjustment ring and the main
frame.
