S&S Cylinder Dowels and O-rings

[Ohio HD]

Max they're 0.263" ID. I don't know if they are Viton, they feel a bit tough. What I orderd and used last time was McMaster Carr 93445K338, they're Viton.

Thanks,  I figure about 0.250 on the hole and that the O rings were likely -011s.  That puts the ID of the o ring grove about 0.315 so the dowel is thin at the groove.   At 0.263 hole the wall thickness at the grove as only 0.026.

I was looking at McMaster. The list each at 8.82 which is pricey. On line could be wrong?  They appear to be dual compound.  Granger has black for about $3 and brown for about $9 in packs of 100.

BTW not trying to insult.  Just asking. I am curious how they worked for you.  You can get 011 viton standards from McMaster in packs of 100 brown for about $9. There seems to be a bug in their selection program that lead me to that one O ring. 

Thanks for the info.  I'm thinking about making a set of the dowels. 7/16 annealed / ground drill rod would be easy to drill and cut to size. I have to come up with a set of dowels anyway.  I had to remove them to sleeve the cylinders.

One thing that is interesting is that I had to setup a VPN to access this place. Did I piss off an admin?

I know I screwed up some time ago asking if someone wanted to sell something.   Got some good info deleted.

My mistake on what I ordered. It was in 2017 sooo..... and I was at work. Here's what I ordered, they work fine, been in the motor since 2017, but not a lot of miles, maybe 5,000.

This is where I get all of my pushrod tube o-rings, etc.

I did find a McMaster o-ring that's not emptying your wallet. McMaster is good if you need things quick. At least for me, one day shipping.

Thanks for the info about ordering the o-rings, but I don't get a hit on the part number 500-0385 using the search engine on the S&S site.  So, where's the best place to orders the dowels?

[Ohio HD]

They're in the 2021 price sheet. So who ever your authorized S&S dealer is can get them.

I updated the drawing with all pertinent dimensions in the event someone wants to make their own.

Larry, I forgot the 0.263" bore through the dowel.     


Fixed on this one.
