ACCUMULATORS DISASSEMBLY/ASSEMBLY
1. Disassemble in the order indicated in the table.
2. Assemble in the reverse order of disassembly indicated in the table.





Accumulator piston disassembly note
^ Remove the accumulator pistons from the converter housing by applying compressed air through the oil passages as shown in the figure.








Assembly procedure
1. Measure the spring free length.





2. If not as specified, replace the spring.
3. Check the seal rings and accumulator pistons, and if any are damaged or cracked, replace them together as an assembly.
4. Apply ATF to the seal rings and D-ring (1-2 accumulator).
5. Apply ATF to the new O-rings and install them onto the stoppers.

O-ring inner diameter
28.1 mm (1.12 in)

Caution
^ Apply even pressure to the perimeter of the accumulator pistons and the stops to avoid damaging the O-ring, seal rings, and D-ring while installing.

Note
^ Installation order
2-3 accumulator:piston-spring-stopper
1-2 accumulator:piston-spring-stopper
N-D accumulator:piston-spring-stopper
N-R accumulator:spring-piston-stopper

6. Install the accumulator pistons and springs.
7. Install the stoppers and snap rings.
