26 Replacing the ‘E’ Stack Assembly
Note : After doing work in either Section 26 or 27 the pressure/flow characteristics can be altered by
moving the coil assembly/’E’ stack nearer or further from the armature magnets. This can be
done by adjusting screws (Fig 13, Item 20). Ensure the screws are tightened afterwards.
26.1 Remove/disassemble the compressor/AV bracket assembly and remove the silencer bag
(Refer to Page 19, Section 22.1, 22.2, 22.3 and 22.4).
26.2 Unscrew and remove the two screws and anti-vibration washers (Fig 13, Items 20 and 30)
which secure the ‘E’ stack/coil assembly (Fig 13, Items 10 and 40).
26.3 Withdraw the ‘E’ stack/coil assembly from the compressor case as far as the electrical wires will
allow.
26.4 Carefully remove the ‘E’ stack from the coil assembly.
26.5 Replace the ‘E’ stack by reversing the operations carried out in Section 26.4, 26.3 and 26.2.
26.6 Fit a new silencer bag and gasket, then replace the compressor lid (Refer to Page 19 and
reverse the operations carried out in Section 22.4, 22.3 and 22.2).
26.7 Refit the compressor/AV bracket assembly to the pump case (Refer to Page 13, Section 15.2,
15.3 and 15.4 (new style AV mounts) or Page 15, Section 17.3, 17.4 and 17.5 (old style AV
mounts)).
27 Replacing the Coil Assembly
27.1 Remove/disassemble the compressor/AV bracket assembly and remove the silencer bag
(Refer to Page 19, Section 22.1, 22.2, 22.3 and 22.4).
27.2 Remove the ‘E’ stack/coil assembly as described in Section 26.2 and 26.3.
27.3 Disconnect the compressor electrical wires from the terminal block. Carefully cut the cable ties
from the pneumatic tubing/cable loom as required.
27.4 Feed the compressor electrical wires through the compressor case cable grommet (Fig 13,
Item 50).
27.5 Remove the ‘E’ stack/coil assembly from the compressor case (Fig 13, Item 60) and carefully
separate the coil from the ‘E’ stack.
27.6 Replace the coil assembly by reversing the operations carried out in Section 27.5, 27.4, 27.3
and 27.2; fit new cable ties where required.
27.7 Fit a new silencer bag and gasket, then replace the compressor lid (Refer to Page 19 and
reverse the operations carried out in Section 22.4, 22.3 and 22.2).
27.8 Refit the compressor/AV bracket assembly to the pump case (Refer to Page 13, Section 15.2,
15.3 and 15.4 (new style AV mounts) or Page 15, Section 17.3, 17.4 and 17.5 (old style AV
mounts)).
