Figure 66. The reverse checkball capsule in the back of the case is replaced. Many just take the ball out of the capsule and leave it empty. It was changed, the new capsule was very cheap, less than 8 bucks, so it was pulled out with the slide hammer and the new one driven in.

Figure 67. The new 3-4 servo checkball capsule was driven in. The Sonnax servo check capsule will be driven in over the top of it. Progress had to stop here while a #31 drill bit was ordered to enlarge the orifice in the Sonnax capsule as per the instructions.

Figure 68. Install Sonnax servo release check valve kit, after drilling the orifice with a #31 bit as per the instruction sheet. Make sure it is slightly below the surface of the case so it does not interfere with the spacer plate.
