below for disassembly and reassembly of the big actuator. For part numbers, see
Figure 22 and Table 2.
1. Remove heat shield (65) by removing the 4 pcs screws indicated in Figure
3. Be careful when last set of fasteners are removed.
2. Use a marker/pencil and mark a line on both jammer plate (22) and
actuator (101). This line will help later getting the actuator back to the same
position.
3. Secure the actuator with lifting straps.
4. Remove the screws.
Do not remove the screws (33) as these are holding the jammer in
place, avoiding the ball segment to rotate due to its own weight.
5. Remove the big actuator by moving it horizontally, out from the valve.
Be aware of the weight of the actuator and always use appropriate
lifting straps!
6. Reverse all the steps above after the valve and actuator have been
transported to the digester top. Make sure to align the big actuator with
the valve using the line on actuator and jammer made in step 2.
