5.4.2.1 Disassembly
When removing wiring only
Remove the indicator cover before pulling out the unloader indicator wiring because the indicator
has a terminal board for wiring. Perform the work as described below and after removing the wiring
reattach the cover for protection.
a) Loosen the
hexagon socket head cap screws [212] holding the indicator glass. Do not
mistakenly loosen the phillips screws [210] on the same surface. Remove the indicator shaft
assembly parts [141], [202 – 207], [210], and [211].
b) Remove hexagon socket head cap screws [147A] [147B] (two each) that fasten the indicator
cover [146]. Then the cover gets removable.
c) Since there is a terminal block [132], remove wiring after removing the surface plastic sheet and
loosening the screws.
