I'm really surprised the piston ring didn't snap when you were stretching them out. They must be steel and not cast steel. Thank God. The way I do them is to just pry them over by hand. If they are over expanded they may wear in the cylinder bores more than if not. Once the motor warms up they should relax just fine. You guys are doing a really good job. Expecially the keeping everything clean part. That's super important. Thanks for sharing.
I know that wasnt the proper way to get the rings on there. But I watched a few youtube where they stretched them with these pliers to get them on

@@FishxScale What I do is take a real fine piece of sandpaper in right on the sharp edge that's going to be against the piston I touch it up a little bit that way I can slip the rings over the piston without stretching them just slip them over like I said without scratching the pistons. You should be fine . Is not like I was on time enough to tell you before you did it. One trick would be To take a hand dryer in warm up the pistons and the rings when you put the piston ring squeezer around the rings before you put it in the cylinder just warm them up overnight in let them cool back down before you try to put them in. By warming them up with a hand dryer you will naturally make them conform to the shape and not overheat them. When I read watching it looked like they where stretched out just...a little bit more than I'm use to seeing them. But that's on Chevy engines that I build a lot of. Like I said. I'm sure your fine but it will never hurt to warm them and let them cool all the way back down before you install them.
Great video Jeff. I'll follow along as the build progresses. Getting ready for the summer fishing season, do it yourself style.
Dude, awesome videos thank you. Tight lines
Glad you like them!
The best 90 hp engine ever built. Took me 6 months to find a good used one. Take care of it ! And make sure those rods arent magnetized before you assemble it all.
Just blew a cylinder on my etech 115! Looking forward to watching the rest of the build. Thanks for the vid!
Good Luck!!!
I figured this out as I went. The first one took an hour to get together , the next two went together in 40 minutes combined.
When you had the cylinder bored I assume they knew to chamfer the ports so it wouldn’t catch a ring again ?
I dont think the machinist did. It was pretty sharp.
Where's Mac?I'm sure he would be a big help. Say hello to Colin hello for me.I really enjoyed this vid.
They do have circlip pliers that has the ends of the pliers that allow you to grip the open ends of the clip. To bad they didnt make the circlips with a slightly larger ends with a hole in it. Then just a cheap Harbor Freight set of snap ring pliers would have made it an easy job.
Yeah I looked them up didnt want to wait/pay for one time use. In hindsight they would have been worth it
@@FishxScale yeah I hate how specialty tools are priced. But in the end you got it done and didnt waste 50-100 bucks on a tool you'll probably never use again. Good job, looking forward to the rest of the build
niCE ONE Thank You ! :)
Thanks you
Do you still have the motor and if so how’s she going
Running Great used it today
With the clips would a socket the same size have been an easier way to knock them in?
Maybe? Idk seems like that could have worked
Great job homies!! Did you use OE parts? any advice would be appreciated cuz OE are liking killing us. thanks
I bought a kit off ebay. Still running strong
What size socket did you use for the connecting rod bolts? I’m using your video to rebuild mine right now.
This was a long time ago. Maybe a 12mm. I have a link to the repair manual let me find it.

@@FishxScale Do you recall using a certain type of socket? My bolts look like 12point, but i cannot get a socket over them as the shoulder of the connecting rod cap is too close to the bolt.
I used a 1/4 inch 12point socket it barely fit
You could have stuck the washer in the freezer for a few hours it would have gone right in.
Like syrup on pancakes lol
Lol
Like your videos thanks for the info. Do you want to partner together?
Great video but such a terrible design by Yamaha, using needle bearings on that pin. That's just an engineer that got beat up in school taking his revenge on everyone LOL.
What i see is u dont no shit about that. The 1 ring is the one from the top...ah,ah,ahOK
