DIFFERENTIAL SIDE OIL SEAL : Removal & Installation: Installation

Note the following and installation is in the reverse order of removal.

1. Measure lip height (A) and determine differential side oil seal insertion reference value (B) from the list to calculate lip protrusion (C).

   (1)	: Differential side oil seal
   (2)	: Converter housing or transaxle case

   Lip protrusion (C)	: C=A-B
   Differential side oil seal insertion reference value (B)	: 1.8 mm (0.071 in)

   CAUTION:

   • Never reuse differential side oil seal.
   • Put a mark on the measurement area and measure height of seal lip at four points diagonally using suitable tool.
   NOTE: Since seal lips have a tolerance of +/- 0.3 mm (+/- 0.012 in) at maximum due to manufacturing tolerances or packing conditions, it is necessary to measure the seal lip height beforehand to clarify the tolerance.
2. As an indicator of the parallelism and insertion depth, cut a masking tape (1) to specified width [add 1 mm (0.04 in) to the value calculated from the tip of differential side oil seal lip] and affix to the differential side oil seal.

3. Install the differential side oil seal using a drift [outer diameter: 57 mm (2.24 in), inner diameter: 53 mm (2.09 in)] according to the guide of the masking tape.
   CAUTION:

   • If differential side oil seal is inserted deeper than the reference value, use a new differential side oil seal and perform the steps again.
   • Apply CVT fluid to the differential side oil seal lip and around the oil seal.
4. Remove masking tape.
5. Adjust as instructed below to optimize the protrusion size and parallelism.
   CAUTION: If differential side oil seal is inserted deeper than the reference value, use a new differential side oil seal and perform the steps again.
   • Protrusion size (A)

     CAUTION: Protrusion must fall within +/- 0.5mm (0.020 in) of calculated size.
   • Parallelism at four diagonal points ( )

     CAUTION: The difference among four diagonal points must be within 0.3 mm (0.012 in).
     NOTE: If differential side oil seal is uneven while installing, tilt suitable tool.
6. Check that the protrusion size and parallelism are adequate.
