Thrust Base
Drive Bush disassembly instructions
This applies to the Bronze Drive Bush case when thrust is applied to the valve.
To process parts in addition to better fit the dimensions the Drive bushing is separated from
the Actuator.
Disassembly
1. Disassemble the bearing Stop Ring’s lock socket set.
2. After separating from the Drive Bush, push the bearing out. Store the Drive Bush and
Stop Ring in a safe and clean place.
3. When processing the drive bush, make sure it is not damaged. This applies similarly to
the O-Ring located on the upper part of the Drive Bush. When working on the Drive Bush,
make sure all measurements and calculations for the valve stem is correct. Make sure
the protective bearing’s O-Ring is not damaged.
Assembly
1. Remove foreign particles on the Drive Bushing. Once clean do the same for the Stop
Ring and other O-Rings. Make sure there is enough grease present. Make sure all O-rings
are not damaged.
2. Push the Bearing assembly and check that the Drive Bushing has securely assembled.
3. Tighten the Stop Ring lock set bolts manually. This also applies the Socket lock set bolts.
4. After assembling the Drive Bushing with Actuator Base tighten the Stop Ring Holder,
with wrench, the head bolts (M4 :2.2Nm M6:7.8Nm).
