Ok, Ive gotten a little closer with these things. I got the oil spreader ring and outter rings put on, the easy part. That leaves the 2 oil rings, 1 ring has a dot nothing else, the other ring also has a dot (which i thought faces up) but its a beveled/chamfered ring on the inside/bottom of the ring which I thought someone said faces up. So if the dot faces up, the bevel won't face up.... also not sure if this is the top ring.

:eek: I hope that was english... its 3:15am

Chamfer on top ring face up.
Chamfer on second ring faces down.
Dots on both face up.
See if that works for you.

Well thats a nice typo ;)

One ring doesnt have a chamfer, its flat.
The other one has a chamfer on the bottom inside (when the dot faces up)

The little paper it came with says:

1-Install all rings marked TOP, "T", or with a dot "." facing toward the top of the piston
2-Install all UNMARKED beveled rings with the bevel toward the top of the piston (I dont think this is me)
3-Install rings with groove at lower O.D. corner of ring face with groove toward the bottom of the piston

The rest doesnt apply it just said stuff about unidentified rings and chrome/moly, but both of these have dots. Is groove and bevel the same? I wouldnt think so, but it doesnt say anything else. Does speed pro have any better specs on there website? This kind of sucks, they generalize it too much, plus Ive never done this. :eek:

First, when you open a ring box,,, pay attention to where the rings are BEFORE YOU TAKE THEM OUT.

Almost all Speed Pro rings sets will have a tab that tells you which rings go in which groove.
It is usually on the end tabs after you open the box on the side that has the little "zipper" to open it.
Now, on to your problem :confused:
These two rings can be of many varying designs but should have a dot on them which faces up.
The bevel in the back of the ring may or may not face up depending on the ring design but the dot always goes up.
If you have one ring with no bevel & a dot it goes in the top groove
The ring with the dot & lower bevel will go in the second groove if the bevel is away from the dot. for this set.

For anyone else reading this, normally the bevel goes up for the top ring & down for the second ring but this is not a given rule.
There are some ring sets that the bevel will go up in both cases.

What is the part number on the ring box?
H426 is a piston number not a ring set number.

BTW,
The block notch in your other post is a valve relief, it has nothing to do with the rings.
But,, you do not want a ring end gap pointed at the notch as it makes it easier to break one while installing.

Both dots face up though. Are you sure thses things did not come with instructions?

EDIT: Hey Mike, you type too fast. How did you get all of that in there before I typed my lousy 3 lines??

I edited twice now smile.gif They did, but there so general! I was pretty sure the dots ALWAYS face up, which clears alot of things up. Both of what you guys said sounds right. 2 rings, both with dots, 1 has an inside lower bevel. These rings are part number E-233K 30

OH CRAP. You guys are right, on the inside flap of the box it does say top groove, second groove and bottom groove. GREAT smile.gif Would have been great!

Yes the bevel is away from the dot.

So the ring without any bevel, top groove, dot faces up. Ring with lower bevel, dot (oposite sides from each other) second groove, dot faces up, bevel will be faving down towards the rod

Of course I don't have a clue what is on most of the time,, it's just noise across the room for a distraction

OH CRAP. You guys are right, on the inside flap of the box it does say top groove, second groove and bottom groove. GREAT smile.gif Would have been great! Ok,, 233K is a generic Moly set so,,, the top ring will be a lighter color on the side that faces the bore then the second ring.
If you look real close it will look like a lighter color with two very thin darker lines on each side.
The lighter color stuff is the Moly & the two dark lines are the actual ring.
What is done is a groove is cut into the ring & Moly sprayed into it.
Use a magnifying glass & look real close

---------edit----------
never mind the magnifying glass,,, I keep forgetting you kids probably don't need one graemlins/sad.gif :D

The one with the bevel is the lighter colored one, its got a pink mark, the other ones purple. When you said the top ring is the lighter color, you mean second groove right?

I am talking about the face of the ring not the paint.
It should be noticeably lighter in color on the part that rides against the bore.
Look at them both with a magnifying glass to see the difference.
Put a pic of the ring facings up so we can see them.
Or wait until tomorrow & have your machinist look at them.
Or get in your car & bring them over here :D
It's only about 3 hours,,,, just kidding,,,

Ok guys,, there must be someone on here in the Sac area that can give Phil a hand????

Oh yeah it is lighter. Well I think we've got this thing wrapped up smile.gif I'll make sure I allign the gaps correctly. Thanks for all the help guys. Im sure I'll be back soon enough... and next time I won't whip the rings out of the box.

One last thing about these rings. I am compressing them one at a time from the bottom up. After I take the compressor off they get pretty big and float back out.

What happened to the instructions that came with the box of rings???

All of this stuff is clearly covered in this paperwork.

You can probably even download the instructions off Speed-Pro/Federal Moguls site.

I know most of it was covered but I havent done this before remember, plus I pulled them out of the box before I saw where they went, we said all this in the post already ;)

Any takers on the ring compressor, they dont get very tight onto the piston?

JIM
Jan 2nd, 05, 5:37 PM
Yes, they can look loose and sloppy on the piston.

But:
1) Are you sure they are the correct rings? I had a Speedpro set that were wrong in the box.

2) Did you verify end gap in the bore?

You use it to compress the rings into the groves of the piston when you are installing the pistons in the block so the assembly will go into the cylinder.

{edit}
Ring gaps are checked with the ring off the piston and pused down squarly in the cylinder.

Don't you have a book?

::sigh::
I thought it was used before and after. Once to get them back to shape and there stetched on, then to get them in the cyilinders... Well I guess that makes sence then. Im not sure how to check the gap size, but the positioning of all the rings and the gaps are really easy to follow in my book and im sure those are correct.

Phil,
Please do not take this the wrong way but STOP NOW!
I know you are trying to do this yourself & it is great that you are asking questions but you need someone there with has done this before or sure as hell you are going to screw something up & it is going to cost you a lot of money.
I know you want to get it done & understand your impatience but there is a very good chance you are not going to be happy with the end results if you keep going without someone to help you by overseeing what you are doing.
Books are great but you have to read them & it is pretty obvious you are not by the questions you are asking.
Again, not trying to bust your balls but I can see nothing but problems if you don't get someone to help.
Putting these things together is not brain surgery but there are things that should be checked you are missing that someone with experience can help you with.

If nothing else, put your tools away, go in the house, shut off the TV & READ YOUR BOOK ON BUILDING A RAT!! Read it a few times & keep it with you when you have a question ;)
