The Type C, D, and E power unit is also retained in lg the container by means of eight shipping bolts but because the closure heads on these power units do not include a bolting flange, a special n shipping ring is used,torclam I assemblytothebarrelfuhp'er' ipth'erclosureheadandcorecartridge flancje 2 cf,the shipping container.
