suntour arx derailleur problems

Put my Schwinn back on the road for the first time in 20 years, made it 4 miles from home when the chain came off. The guide pulley retaining bolt worked loose leaving the pulley somewhere on the road. The bolt got caught up in the works when the assembly rotated around the pivot. After some searching I found the pulley, no worse for wear, further searching revealed the flanged aluminum washer had been run over by traffic and was not salvageable. How important is that flange? Seems I could find a suitable washer, or its off to ebay to find some parts.

The parts are Suntour ARX. 10 tooth 6mm pulley I believe.

Regards
Gary

The pulley is unlikely to run smoothly without the flanged washer. If you have friction shifting, there's no need to be fussy about the pulley; you could likely salvage one off an old derailleur in your LBS's or co-op's scrap bin, or buy new:

There is no reason that a standard washer would not work temporarily, as long as the hole is bigger than the bolt diameter and the outer diameter of the washer is smaller than the original. I do agree that it should not be a difficult challenge to find a scrap pulley washer that will work, however.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!
