Where to find Pro-X rings

[jts32]

Bought a ski that swallowed a bolt down the intake and stripped the RV gear. Tore it apart and found it's been rebuilt with +1mm Pro-X pistons and a Hotrods crank, and all are in good condition. Wanted to re-ring, and bought new Wiseco rings(8300FL) that said they were for the Pro-X 01.5508.100 pistons, but they aren't correct. The rings I that showed up are like OEM, "L" shaped top ring and thicker bottom ring. The pistons I have use the same top and bottom rings, but can't find any place that sells them. Please help. Thanks.

Pro-x uses Rikken rings just like all Japanese manufacturers. Look up the part number for your model on their site then just google. Should by pretty easy.

I've googled, checked Rikken's sight, and Wiseco's site. Haven't been able to find anything but the 8300FL rings which say they are compatible with the part # on the pistons I have. Guess I'm just gonna have to call Wiseco and/or Rikken and actually talk with a tech guy. Both of their websites are sh*t for finding specific parts for a 20+ year old ski

Directly from Pro-X site, part number is 02.5508.100, OSD Seadoo has them listed.
Also WSM uses the same rings so 010-917-07 are the rings from WSM for the 720 seadoo 1mm over and should work as they are both Rikken rings.

Thanks Miki. OSD didn't show any in stock. The Pro-X # 02.5508.100 cross refrenced to the Wiseco # 8300LF so that's what I ordered. I need both rings to be flat, but the kit I got has the L shaped top ring. I know the WSM pistons I've ordered before also have the L shaped top ring, but those were the Platinum series. Do standard WSM pistons use 2 flat rings?

 

[mikidymac]

Pretty sure all the WSM ones I have gotten have the two flat rings but I guess I never really paid attention. The only ones I really remember for sure are the OEM ones with the "L" rings.

I know Wiseco now owns Pro-X so it really shouldn't be that difficult for them.

Finally got the correct rings. The rings have a flat side, and an angled side. Does it matter which direction they are installed?

 

[jts32]

Nevermind, I figured it out. One set came in a WSM package with no instructions, the other set was in a Rikken box which said install with marked side(angle) up

Any marks always face up on all rings.
Glad the WSM ones got you set. Not sure what Wiseco is thinking.
