30.2.2 Adjust adjustable axle (87) (Fig 6.3) until block ceases to rock.
30.2.3 Tighten locking screw (5) and recheck block for stability.
30.2.4 Repeat Para 30.2.1 to Para 30.2.3 if necessary.
30.3 Refit two plunger (carriage assemblies) (25), springs (26) and spring plugs (27) removed at
Para 24.7. Ensure ends of spring plugs (27) are flush with front face of balance mechanism block (166).
30.4 Continue refitting procedure at Para 31 or Para 32 as appropriate.
31 If it has been necessary to change any of the buffer pads proceed as follows:
31.1 Temporarily attach platform assembly (38) by a reversal of procedure at Para 9.2 to Para 9.4.
31.2 Using two sets of feeler gauges measure clearance between loading bars (119) and (130) and
load beam (174) and note dimensions, which should be approximately equal. Care must be exercised
to ensure no bias is put onto loading bars during this operation.
31.3 Remove platform assembly as detailed at Para 9.2 to Para 9.4.
31.4 Peel laminations from new load beam shims (13) (Fig 6.2) to achieve dimensions noted at
Para 31.2.
31.5 Assemble shims into position and retain each with two M5 button head screws (14) passed
through load beam into respective loading bar. Do not tighten screws at this stage. Final tightening is
performed during refitting of end plate/adjustment shaft assembly.
31.6 Continue refitting at Para 33.
32 If no buffer pads have been changed proceed as follows:
32.1 Refit shims removed at Para 24.9, ensuring same orientation as removed.
32.2 Retain shims with two M5 button head screws (14) passed through load beam into each loading
bar. Do not tighten screws at this stage. Final tightening is performed during refitting of end plate/
adjustment thread assembly.
33 Continue the mechanism block assembly refitting as follows:
33.1 Refit cross members as detailed at Para 23.
33.2 Refit main spring and end plate/adjustment thread assembly as detailed at Para 19.
33.3 Refit front cover as detailed at Para 17.
33.4 Refit top cover as detailed atPara 15.
33.5 Refit platform assembly as detailed at Para 13.
Base assembly
34 The base assembly (either spherical (266, Fig 6.12) or flat (276,Fig 6.13) is removed by unscrewing and
removing the four M5 socket cap head screws (Fig 6.1 item D) and lifting the head from the base. The base is
refitted by a reversal of this procedure.
