Assembly procedure

NOTE:
- Installation order
N-D accumulator: Spring - Piston
2-3 accumulator: Piston - Spring
1-2 accumulator: Piston - Spring
3-4/N-R accumulator: Piston - Spring







- Outer diameter of spring







1. Apply ATF to the new O-rings and Install them onto the accumulator pistons.
- Apply even pressure to the perimeter of the accumulator pistons during Installation to avoid damaging the O-rings.




2. Install the accumulator pistons and springs.
