moved for replacement. To replace parts, remove them in the or-
der of 1 to 18 as shown in the table. To install them, reverse the
removal sequence.

represent the numbers in the “Location of major mechanical
parts” table. Also, the “T”, “B”, and “T/B” on the right of each part
name shows that the particular part is removed from the front,
from the back, and from both sides of the mechanism, respec-
tively.
