polished sealing surface. If damage is found, discard the
crown, and do not attempt to reuse. If it is in reusable condi-
tion, set it aside on a soft surface to prevent damage to the
sealing edge.
26. Stand the box bottom upside down on a padded surface, so
that the vane adjustment switch(16) faces down, and the
exhaust side of the box bottom faces forward.
NOTE: To prevent the part from becoming lost in the pro-
cess of removal, place a shop rag over the outlet boss of the
box bottom before performing the next step.
27. While holding the box bottom secure, place the tines of the
Circlip/ Retaining Ring Tool squarely against the ends of the
circlip(19). Gently press the circlip straight off the vane
adjustment switch (see Fig. 6), and set it aside.
28. Pull the vane adjustment switch out of the box bottom. Re-
move and discard the O-ring(15), and set the switch aside.
29. Place a medium blade screwdriver approximately
2
inch
inside the top corner of the exhaust cover(34), and press the
exhaust cover between thumb and screwdriver (see Fig. 7a).
While holding the box bottom horizontal and secure, pull the
exhaust cover out and away from the box bottom only until
that corner of the exhaust cover is disengaged.
30. Turn the box bottom vertical and press the disengaged side of
the exhaust cover up from below, rotating it over the box
bottom until the opposite side disengages (see Fig. 7b).
31. Remove and discard the two exhaust valve diaphragms(6).
This concludes the disassembly of the Micra ADJ sec-
ond stage. Refer directly to Procedure A and Table A,
titled Cleaning & Lubrication, before proceeding to the
Reassembly Procedures.
