Now that makes a lot more sense, seperating the gaps position will increase the compression. I know 1 side of the ring is sharper than the other, make sure the sharp end is the bottom to prevent the oil from leaking through to the combustion area.
Ring gap position is actually pointless.Because rings turns in grooves randomly due to vibration,you cant control it.Only two strokes keep rings stationary,due to pins on piston.You can allign all ring gaps at installation,if ring gaps are what they should be,compression will be 100 percent and oil consumption nothing to speak of. Far more important is lack of info and clarity by some manufacturers what should be top and second ring and clear markings which side up
Old post, I know, but this is absolutely NOT true. A lot of four stroke pistons even have small notches inside the ring lands to help you align the rings to a specific spot, and those notches will absolutely not allow a ring to spin. Rings should NEVER be spinning inside the bore. If they do, you have a problem.
@@bluegizmo1983Some of them are really confusing. For my 110cc kit they are 99% arr the same. And their machining angles are against the industry traditions that you can find on internet. I don't know why they have a secret code to install some super primitive pieces... What I only believe is 2.nd ring is a little bit thicker and harder.
I always put the gap of the ring away from the exhaust valve if possible. I also use a ring spreader. It helps the possibility of a twisted, out of round ring or damaged grove. Use the ring tool.
That is only really important in two stroke engines because in four strokes the rings can (and do) move around freely and one will probably face the exhaust anyway. I agree for two stroke engines, it is vital to do so to avoid ruining the engine once the rings get a bit too hot.
@@williamjacksebastian I'm not sure if what your saying is correct. 4 stroke engines not withstanding. Piston rings in 4 strokes "do not" move around freely, unless it's a super worn engine. First of all, the Pistons, with rings are installed with a piston ring compressor. Why? Because the piston rings have to be squeezed to fit the bore, and they will "expand" exerting spring pressure on the walls of the cylinder to make a tight seal. This spring pressure, that can be several pounds, holds the piston rings in place, therefore, they Do Not move around "freely" as you say. And yes, piston ring position does matter, and it is logical that you start the upper compression piston ring pointing away from the exhaust port, because you don't want the hot flaming exhaust gases to enter the piston gap. It's heat will distort the piston rings, it will reduce lubrication of the cylinder walls and increase blowby. So, no, piston rings Do Not move around freely. They are not designed to move around freely, like my Nuts....
@@Pork-Chopper My expertise leans much more toward two stroke engines however I have rebuilt half a dozen four stroke engines, I was always told that the rings are able to move freely and have not required any special equipmement to install them.
I have always been able to slot the piston in slowly compressing the rings with a small piece of metal or wood one by one, and yes I am very aware they fit the bore otherwise there would be no compression. They are not held in place by pins like on two stroke engines, and I'm going to go ahead and read up on if they can move on their own or not!
Oiling the ring lands is asking for trouble, that oil will turn to carbon when the engine fires and runs for a while, you only lube the skirts below the rings, and the cylinder walls, that's more oil the the top2 rings will ever see, and the engine won't puff blue smoke when you fire it,
True, but you generally can't reason with a mechanic. He will keep oiling ring grooves, fouling new plugs, and gumming up the compression rings. Oh well.
Spacing ring gaps less than 180° apart give combustion gases an easier path, space them ALL 180° apart, starting from the top ring down top gap at top of cylinder and second bottom of cylinder, oil expanders 180° also
I never understand why you would even stagger the rings because they rotate when the engine operates. I have removed many pistons. All the gaps tend to go to one spot.

You lost me when you spiraled the 2 nd oil scraper ring into position.....bad move! This will pull a burr off the soft alluminum and place it in the ring groove ..,then the ring will stick and cease to rotate...burning the ring and the cylinder wall .....rings MUST rotate!!! Use a ring spreading tool as instructed by ALL piston and ring manufacturers!!!
Simple logic dictates that the two compression rings should have their gaps positioned 180 degrees apart. The gap for the oil control ring is not sensitive to position, but logic again suggests that it not be placed on the "thrust" side of the piston, thus allowing a less sressful break-in for it. You can either install rings in the fashion that is recommended for stupid mechanics, or you can use your brain.
For all the engines I’ve worked on, I never put compression ring gaps on the major or minor thrust locations. So nothing inline with the wrist pin, nothing perpendicular to the wrist pin. 45° to one of those is fine, and 180° between the 2 compression rings. All my work has been on large diesels (1200-4500hp) but same theory applies to all IC engines. The oil ring I usually clock the gap at 90° from the bottom compression ring.
What complete and utter rubbish! This video perpetuates the tired, old erroneous myth that circumferentially separating the ring gaps somehow 'helps' engine compression - IT DOESN'T!! Not a shred of difference because the rings rotate in their grooves (unless pegged, eg 2-strokes) (around ~ 150-200rpm) while the engine is running. You fools!!

It is absolutely correct because each rings installed opposite direction.

Great video. I've been looking for one like this straightforward!!
Wouldn't it make more sense to place 180* separately? For 180* compression leak. when you do it will be 120*. let me know if i'm wrong.
I agree with you, however there are people who say the rings rotate while running 🤷…

Most important aspect is to set the ring gap properly.
Right
Very wrong piston ring position.. never ever put ring end gap on piston pin hole..
If you ever played attention when you take the piston out of a run engine it is just as likely to be there as anywhere else
What happens if u do plz help us
Bullshit
@@chegechegeh4545 nothing
Neither should you put ring gaps on thrust side of piston
Nice bro 💘
Thank you for watching
Hastings says not to spiral the compression rings on but then you have to expand them a bunch. Not sure which is worse

You never twist the top rings into position. Use the right tool.

Split the ring with your thumbs and place it carefully into the groove, You're putting too much stress on those rings, they'll probably break later
you are right. I was very careful while installing the loops. Thank you very much
Yep.. I follow this way while removing and installing.. It's good approach
Hi, i am busy working on my compressor, but after re-assembly the piston feels rough. Any advice?
Check that the piston rings move easily inside the cylinder and that the connecting rod is installed correctly or not
Why did you install shiny ring as the second and black as the first?
I have received a lot of comments and this is the first comment that mentions this error, I apologize for this error

where is piston cup located?I didnot find any video related to this!
What is the piston cup 🤔

I am pretty sure this method would result in broken rings if the oil rings were the cast iron one piece type.
Welcome. Thanks for the comment, but it works after installing the rings a year and a half ago
It doesn’t matter how you stagger the rings as they rotate as soon as the engine fires
❤️❤️❤️
Thank you
This is a 4stroke piston and have no exhaust port and flush port
That way can break those rings easily

This exactly how not to do it!!! use ring pliers!!!!
I promise you
Use piston ring expander
Thanks you for the clarification. I'll do it

This applies to any small engine
How to tell which is whitch
Thanks for watching, but I didn't understand the meaning of the question
I never understand why you would even stagger the rings because they rotate when the engine operates. I have removed many pistons. All the gaps tend to go to one spot.
The piston and rings do not move in a circular motion inside the engine until they move
Great explanation you are ryt the rings doesn't rotate coz if they rotate the smoke can occur
i think its a heavy bike engine ?
This is a multi-functional engine but not much different from a bicycle engine
As long as the gaps are staggered it doesnt matter exactly which way the go. Itll still work
Actually any way, but what is important is the spacing of the rings

Absolutely the wrong way to install the rings. NEVER spiral the rings into place use a ring expander. Otherwise they are now junk.
Wtf ? He didn't show rotation if rings gap placement location before dropping piston in ? Wtf ?
WRong position
Its very wrong position bro dont do this because cunssuming oil after also breater smoke to much
