2 2) DISASSEMBLY AND ASSEMBLY () Remove the rubber boot(2), unscrew the handle(7), remove the cables(30) (2) Retain the lever pivot(6) and unscrew the locknut(5). This will allow removal of the lever pivot together with the prefeel assemblies(0). Ensure that the prefeel assemblies are identified, without damage, and can be returned to the same bores. Clean all parts, particularly the armature and magnet faces and check for any sign of damage. The universal joint, which is held with a locknut, need not be unscrewed if there was no free play in the lever mechanism (3) The four capscrews(9) holding the magnet retaining plate can now be unscrewed. Torque limit :.02kgf m(7.38lbf ft) 9 () This will release the hold coils(22), blanks, prefeel cage assemblies(2), spindle guides(3). These can all be removed but ensure that they are identified so that they can be repositioned in the same bores

3 (5) The spindle guide/operating shaft subassemblies are now exposed and can be removed and disassembled. These contain an O-ring seal on the insert diameter and a rod seal/wiper inside the bore. These O-rings and seals can be removed and new components fitted. Ensure that all parts are clean before refitting. (6) The piston assembly() can be removed from its bore, together with the return spring(3), again ensuring that each assembly is identified so that it can be correctly replaced. Take care to note the positions of any shims if the sub assembly is disassembled as these are critical to the performance. The assembly is disassembled by removing a C washer at the top of the assembly. All other parts can then be removed. Replace any parts necessary and rebuild

6 2) DISASSEMBLY AND ASSEMBLY Servicing intersection seals () After ensuring that all external surfaces are clean and with the valve stood on its mounting feet loosen all tie rod nuts. (2) Stand the valve on its inlet cover end and remove each of the tie rod nuts from the upper end of the tie rods. Lift of the cover, check for damage, remove the existing O- ring seals and discard. (3) Remove the uppermost section, check for damage, remove the existing O-rings and discard. Repeat for the other sections. Ensure that the sections are laid out in order so that they can be rebuilt in the same order. If the valve is disassembled in this way always ensure that new seals are used when rebuilding. 6-82
