As a rule, you'll need to purchase an appropriate re-seal kit for your accumulator. You will then need to disassemble your accumulator, clean everything and reassemble the accumulator with the new seals that came in your kit.
Mostly used in automatic transmissions, the accumulator piston is located in the accumulator. The accumulator consists of a cylinder and spring loaded piston and is used to provide fluid to the internal shifting servos at a rate higher than the pump can provide. Between shifts, some of the fluid from the pump id diverted to refilling the accumulator for the next shift.
A piston seal is a gasket designed to keep fluid from leaking around the piston. Piston seals are commonly used in brake calipers.
The piston rings create a seal between the piston and the cylinder wall.
The cycling switch (located on the side of accumulator) is probably faulty. This is an easy fix, screws into the accumulator.
You need a gunsmith.
A leak
it would be better to buy a piston kit. It wouldn't be a good idea to try to fix a cracked piston.
Replace the seal.
Replace the seal.
you don't fix piston rings. if you have bad rings you have to pull the piston and replace them. on most vehicles you have to pull the engine, then you take off the heads and oil pan. unbolt the caps from the bottom of the rod and push it out the top.
When there is to much resistance to retract the piston, When the rubber piston(s) boot/seal is damaged/torn, When the bleeder is broken/stripped,
well.. u can seal it with m-seal or any other adhesive to fix the problem!! as simple as that!!
