NOTE:

Due to standardization, replacements in the
parts list may be different from the parts
specified in the diagrams or the components
used on the set.

-XX, -X mean standardized parts, so they
may have some difference from the original
one.

Items marked “*” are not stocked since they
are seldom required for routine service.
Some delay should be anticipated when
ordering these items.
