Eventually and (we think) very importantly, We have now a whole J71 Autopark method that has been transformed to your benchtop examination station. It has been modified using a force gauge and alterations from the valving and wiring which allow us to make use of it for rigorous testing with the repaired cylinders.
is located about the star wheel. The port is NOT from the backing plate as it was from the previous family car or truck.
 As a result, many of the size we is going to be utilizing are likely to be approximations. When not best, they will be very well throughout the limits of accuracy essential to elucidate the workings with the technique.
