Note the following, and install in the reverse order of removal.

• Using a drift (commercial service tools), drive the side oil seal within the dimension (C) and (D) shown as follows.

  

  	: Left side
  	: Right side

  Dimension (C)	: 2.6 ±0.3 mm (0.102 ±0.012 in)
  Dimension (D)	: 3.45 ±0.3 mm (0.1358 ±0.012 in)

  CAUTION:
