Does anyone know where to buy this tool?? The part # is PN 2870962. My local Polaris guy said it is no longer available. I've looked online and have not had any luck yet. It looks like a socket - open on both sides. One side is used to get that U seal in place without damaging it. The other open end is used to press the outer seal/metal band down into place. I've already damaged 3 U seals.
