Installing rings where to clock them?

Re: Installing rings where to clock them?

they all rotate as the same rate.

Really? Never thought about that, but it would seem that would be different since they can have differing widths, tensions, rates, materials, coatings, cuts...

There you go thinking again....what did we say about that?

Yeah, I am not buying that! Andy you went and gas ported yours too, so with the added psi on the top ring it may not move as much as it once did, becaused its now "pinned" aganst the cylinder wall even harder.

I always clock them the way the manufacturer says and everytime I take them apart the rings are everywhere.

Probably the best answer yet.

They rotate - but not at any particular speed or direction. We have some tracked once upon a time - I think they used a radioctive pellet on them - and it was like 12 RPM and moving back & forth a bit to boot. No rhyme nor reason.

If you screw up the wall finish they'll spin like hell and wear out in a hurry. Screw up the shape of the cylinder and they gaps'll line up over and over.

Punchline is just don't line them up.... worry about other things.

Re: Installing rings where to clock them?

I could be wrong.

I am only basing it on engines that I ahve built that had issues right away and I took apart....they rings were all oriented the same as before but had rotated. The only reason I noticed this is because I had put the rings in only a day or two before and was curious!

Re: Installing rings where to clock them?

I put mine 120 degrees out from each other. Making 360 degrees around the bore. I dont know if this is correct, Like alot of the other Post, I to believe they rotate. I think that Accuracy in Bore and Torquing consistancy is more important.

Re: Installing rings where to clock them?

A friend of mine was running a small motocycle workshop. He rebuilt a small 2 cyl Suzuki for a customer. afew days later it comes in fuming and fouling plugs. He pulls it down and all clearances are good but strangely all the ring gaps are lined up. He rotates them a bit,the book recomends 120 deg apart.The bike runs good now but he has that uneasy feeling you get when you know somethings not quite right. A couple of days later the bike is back- same problem. After a LOT of head scratching,(and the customer looking at him like he's a turkey) he works out that when the barrel was bored it had a little bit of dirt or something under it when it was mounted(the shop owners know-it-all son did this job-typical!) the bore was the right clearance ect but offset at an angle to one side. It was cheaper to buy a second hand barrel and have it re-bored than buy new pistons ect. If it was mine I would still probably be scratching my head wondering what the hell was going on!. I think the rings do rotate at different rates. Makes you wonder how many times they line up.Or do combustion pressures move them apart?

Probly the OEM's are the only ones who know for sure.

Re: Installing rings where to clock them?

I stagger em randomly on the oil rails (both away from the expander's gap), and the top 2, 180 degrees from eachother, both in line with the skirt area. They WILL move around during running anyway, or you'd see prematurely "stuck" rings in the ring lands otherwise from various deposits

OK a question came up this weekend while file fitting and installing my rings. The instructions with the rings show how to clock the gaps away from each other when installing. But then the subject of where to place them on the piston in relation to the combustion chamber when the piston is in the cylinder. I have never heard of this and thought maybe I could get some car junkie feedback on it. Thanks for any input.
