GL1100 Piston Ring Replacement

Postby dvcruz » Fri Nov 14, 2014 3:24 pm



Hello to all.

I'm surprised not to find a "How to replace your piston rings" thread anywhere. Am I missing them somehow?
Anywho... my '83 sat in a garage in pieces for 15 years until a few years ago when I rescued it and rebuilt it from one end to the other. I did not do anything with the pistons or crankshaft itself, but everything else got a good going over. Lately it has been burning oil and after pulling the heads off, I can see where the numbers 2 and 3 cylinders are letting oil pass through. I can no longer ride the bike because I'm blowing so much smoke on the right side.
Much as I don't want to, I'm going to replace the rings and I'm looking for some advise like "be careful not to do this", or "be sure to do this". You know, the words of wisdom anyone might have to pass on. I've done this kind of work on cars and other bikes, just never on a Goldwing specifically.
Can anyone suggest a good place to buy the rings? I plan on doing all four sets and $$ x's four is a lot of money to me.
So, anyone got any advice before I begin? Any thoughts will be appreciated.

Thanks,
dvc

Make sure you can get the rings you'll need before you bother tearing the engine down.

Well it requires splitting the cases..and a gasket set that's $180 and then you should get OEM head gaskets $80, and then the rings ????; maybe finding a new engine a better idea??? They can be had for $200-$300..and then you'd have a ton of spare parts or could sell off the heads, stator,pistons etc. and get all or most your money back.

Just test it for compression..+150's good, 160's great, 140's just OK..

That's pretty much it: simply splitting the case (or more accurately, re-joining it) will cost you more in gaskets than you can find a used engine for. Pretty much the only time people split them open in order to repair them is for fun (?) or because they know the history of, or are particularly attached to, that engine.

The exception is in countries where the supply of used engines is scarce or nonexistent, and the cost of shipping in one from the US is extremely prohibitive.

One more thing..sometimes the rings lock up but after a 100 miles or so they loosen up and work like they should worth a try if that doesn't do it then putting a little 50/50 ATF/acetone mix in each cylinder letting it sit for a few days..change the oil and then riding it for a while might fix your problem..

Thanks for the comments so far.

RB I've heard of putting various fluids into the cylinders to "loosen" the rings but I've wonder how well that could work. Since the cylinders are horizontal, you would have to completely fill the cylinder to get fluid on all portions of the ring. Otherwise, you will only get a portion of the rings soaked. The location of the spark plug hole wont allow this.
So... I was thinking.
If I were to remove the engine from the bike and set it on it's side, I could put some ATF\acetone into each cylinder and cover the rings equally. I could add a few ounces and maybe every couple hours turn the crank to swish things around. Initially, I would think the fluid would seep past the rings, but in time, assuming the rings loosen up, they should provide a better seal.
I'm already at the point where I have nothing to lose, but what do you (or anyone else think)?

The spark plugs are on the top. Remove the spark plug and fill the cylinder with your penetrating solution. Some cylinders are going to have open valves, so you'll have to rotate the engine to do only the ones with closed valves, perhaps on the compression stroke. Just make sure you give the engine a good spin with starter and with plugs OUT before trying to start it, to make sure the solution is completely out.

FYI...I have a 1980 .gl1100 with 154000 miles on it that was used as a commuter and neglected, then sat for 6 years outside some of witch the timing sight plug was left out. I tore it down to put bearings in it. Words cannot explain how FILTHY the engine was inside and out! I bought a set of new "will fit" rings, and when I checked the gaps, the will fits were about .020, and the stock rings were about .006-.008? which is GOOD! I doubt you have a ring ware problem. Maybe stuck, or head basket, or valve guides....?...oh...I reused the stock rings, and I have the new ones on ebay. I've put about 3000 miles on it, and it does great. The heads must be re-tourqued after 1 heat cycle.


My exercise bike is a goldwing.
