? On Correct Order of Rings

[Scott(IN)]

I have all the parts now to put back this 277 engine, but do not have any instructions for installing the rings. Is this the correct way for the rings? I know the first three are right but the last two could be turned around. Also on the second and third ring, it has a bevel on the inside on one side. Does this go top or bottom?

Oh man- you got the one ring set in the world without printed directions? The second and third rings 'might' have a small dot a half inch in on each ring, if so, they face upwards... bevels??? UP too I think, but if no dots, wait for a another response here. I feel bad cause I just threw the package my rings were in in the trash... in the morning I will look for another package in the shop.

I'm sure you have the rings in the right order, beveled edge facing up. Are you doing a diesel? I don't remember the gas having 5 ring pistons. What kind of a kit do you have there? That bottom 3 piece oil ring can be a sob to install, if there is no instructions, place the center spacer in the groove, hold butt ends with your thumb towards you, roll top ring around and into place and then do the bottom one, with the butt end of the spacer at 6 o-clock, you want the other gaps at 10 and 2 o-clock. Make sure that the thin rings stay on top of the spacer and don't get off and alongside and bind in the ring groove. The assembly has to move free in the groove. Assemble every thing dry and then oil before you install the ring compressor, be sure to stagger all the rings on the piston and it's always a good idea to push the rings into the cyl and check the end gap. I usually mount the piston on the rod and with a clean rag clamp the rod in a vice with the piston down tight to the vice, makes it easier to install the rings. This is getting long but I made a piece of light channel with holes drilled to go from a short head bolt in the rear to one of the 3/8 bolts in the front to hold the sleeves in while I'm doing bottom work with the engine upside down and turning the crank etc, you do not want to push a sleeve out of place, especially using sealer on the o-rings, I'll quit preaching, good luck.

From looking at the oil ring those rings were made by Hastings. Go to there website and see what it tells you, but usually the bevel goes up or a dot goes up if it has one.

Always remember what it's like to be with a good woman, - "In and up, Down and out".

Bevel on the inside always goes "Up".
Bevel on the outside always goes "Down".

Chromed or plated compression rings are always the first ring from the top, if only one is fitted.

Solid oil control ring will always go "below" the gudgeon, if only one is fitted while muti-piece oil control rings always go "above" the gudgeon.

This is for a 277 gas. The parts came from Montes out of Chicago.

3 piece oil ring goes above wristpin, one piece oil ring goes below wristpin when used. Non turbo diesel used this arrangement, gas and turbo diesels did not use the lower ring.

oooooohhhhh. sorry I asked...oh. I didn't ask, so I don't need to be embarrassed?
Now after all this time, I now know what the sheila in Canberra was going on about. She wanted me to overhaul her engine!
We call gudgeons here 'wrist pins'... oh! and that's what the sheila from Fremantle was on about!!!
And I remember diesel tech has a good point here, the 3 piece oil ring goes above the gud...wrist pin....

Ahhh....it's all starting to make sense now Tony!

He's been around the block that is for sure.
