This little tool is needed to replace the seals on SY accumulator control valve bobbin pistons. Carefully remove the old seals with an X-acto knife, then the tapered tool can slip into place on the the short end of the piston. The new seals can then slide into place with fingernail pressure - assuming you have strong nails. In the final pic, the seal has not relaxed to it's final shape, but it will in just a few minutes.
We also have SY ACV rebuilding kits available under the "Parts" tab.
This tool is only for SY cars running RR363.
