Uh-oh!

We all make mistakes. I completely rebuilt a Trident engine and had it back in the bike. I was cleaning up my work bench and found a tiny plastic bag containing the dowels that went in the join between the cylinders and the cases. The entire top end had to come back off.

I blame being ill with flu for that time I forced a 650 barrel on backwards, so that a dowel cracked the barrel base flange.
 
I’ve been extremely busy lately and haven’t had a chance to tear the bike back down again. After talking to Greg I’m convinced that I improperly installed the rings the first time and flattened the red side of the ring allowing the overlap. I will post pics as soon as I tear it down. I’m not afraid to admit my mistakes and I’ve committed quite a few during this endeavor. If you don’t make mistakes now and then you’re not gonna learn anything.
We all make mistakes and we all try and not make the same mistake twice. All part of the learning curve...
 
Yep - happens to the best of us but seemingly more often to slow learners like me …
excerpt from my build log -
Addendum - Made this mistake before but of course I didn't learn from it enough to not repeat it -
put the carbs on the intake runners first THEN fasten the runners to the head if you want to be able to tighten the inside nuts on carb flanges...
 
As promised, pics of the rings. The pictures speak for themselves.

Got the bike tore down and and parts cleaned for reassembly tomorrow. I’ll try to install the rings correctly this time.
 
I can't find it. A couple of us posted example photos.

But, I found these:

Sorry, quite right. But, there was this:
""been extremely busy lately and haven’t had a chance to tear the bike back down again. After talking to Greg I’m convinced that I improperly installed the rings the first time and flattened the red side of the ring allowing the overlap. "
So, just wondered if the red end, which looks damaged, failed as a result of how it was installed? Hinges on how certain Larry is that this is definitely how they came out of the packet

The damaged red end was due to improper installation not bad manufacturing. The rings came out of the packet undamaged. I just installed them wrong/overlapped.
 
I installed new Hepolite rings today. I must say the two piece oil expander ring is much less confusing than the rings previously used. Everything went back together nicely. Torqued the head down and called it a day. I’ll finish up tomorrow.

Larry, I guess it's obvious, but the times I've missed the obvious... have you found the bits that make up the rest of the red ends. That was the point I was making earlier on. Simply, you don't want them rattling around inside. 👍

I did find a couple of red bits the first time I removed the rings. I have a magnetic sump plug so I'll check that when I change the oil. I'll also check the magnetic plug in the oil tank along with a new oil filter. In hindsight, I should have drained the oil while the top end was off and I could have also had a visual inside the crank cases. Hopefully all the bits will be gone after doing the above.
 
I didn't get around to working on the rebuild today as life got in the way. I did however make a new gasket for my intake manifold. Maybe life will allow me to finish up tomorrow.
