(16).A.Alternative Procedure. Remove the remaining stage 1 lever arms (01-050) (SIN 071D1) and (01-180) (SIN 071C0) from the case half (15-010) (SIN 073A0) or (15-011) (SIN 073A0) as follows:
(a)Install the upper stage 1 sector (item 2) or the lower stage 1 sector (item 14) of the 11C3305   countertorque tool on each side of the stage 1 ring segments (01-030) (SIN 071A1) and (01-040) (SIN 071A6) at the flange split line until the block (item 6) touches the case half.
(b)Install the threaded screws (item 7) of each stage 1 sectors (items 2, 14) into the stage 1 ring segments (01-030) (SIN 071A1) and (01-040) (SIN 071A6).
(c)Hand tighten the threaded screws (item 7).
(d)Remove the nuts (01-010) (SIN 071K0) that attach the lever arms (01-050) (SIN 071D1) and (01-180) (SIN 071C0).
