shimano pedal rubber sealing ring

I disassembled my Shimano PD-A530 pedal (see http://techdocs.shimano.com/techdocs/index.jsp) (similar to PD-R535, PD-R600, PD-5500, PD-6600) I used the TL-PD40 tool to unscrew the plastic lock bolt but it crushed and damaged the rubber sealing ring between the lock bolt and the pedal shaft. In hindsight I should have removed the rubber sealing ring first. Shimano does not sell the rubber sealing ring separate from the pedal shaft assembly. Does anyone know any other source for these rubber sealing rings?

Thanks for the suggestion. I wound up reusing the sealing ring. When I compared it to the one from the other pedal it was OK, not perfect but OK. I didn't want to use an O-ring because I was concerned about resistance from too much contact between the stationery pedal shaft and the rotating pedal. I took the pedal apart to use lighter grease to free up the peddle. Thanks again for your idea, it got me thinking and helped move things forward.

an O-ring, my guess is you're likely to find one that fits
among ACE's offerings or maybe Home Depot's, which is likely
even more comprehensive.

ACE also has flat rubber and composite O-rings of various
sizes that might meet your needs.

Yah, Shimano makes nice pedals, but those environmental seals tend to be pretty cheesy. It's important to keep those clean and put a drop of light lube on them on a regular basis. The main reason they deteriorate is that they dry out and stick. Once they start to stick or bind, they often break or disintegrate. A little ExtraDry or TriFlow is the solution.

Using an o-ring is a good suggestion, if you can't get the seal. Just make sure and grease it when you put it on. Then, as above, keep it as clean as you can and keep it lubed.

All that being said, you should be able to get those seals from Shimano, by way of your LBS.
