What a great accomplishment! I'm not sure why I hadn't come across your videos until relatively recently, but at least I'll have something to look forward to watching. Tearing this Yamaha twin crank apart reminds me of many years ago having a small shop in a small town. It was Blown Crankshaft Week, with an XR200 Honda, an XT500 Yamaha, and an XS650 twin all suffering the ill effects of low oil and high rpm, resulting in all 3 seizing the con rod to the wrist pins and snapping off. The XS650 was the first (and the last) twin cylinder built-up crank we'd ever needed to repair, and of course we had to send it out as we had neither tools nor knowledge to repair it, so with this video, the mystery is solved, labyrinth seal notwithstanding. Unbelievably, that Honda was totalled, with the freed piston destroying the valves and guides, and the flailing rod breaking the cylinder, punching thru the front engine case and destroying the frame mount, then flipping backwards and breaking the mainshaft and some gears. Brutal! Congratulation again, and thanks again for doing these videos!
Hey Wayne welcome aboard, I do a lot of different stuff, you may not see on the other channels, I try to incorporate machine work that is applicable to this hobby. Most find it interesting, seeing what's done. Most folks just drop their cylinders and other parts off at the machine shop or bike shop and don't know what actually goes into their repair. Yes indeed, blown crankshaft week for sure. Stuff happens as they say. Cool story!!
What a cool Friday night, after a day of gym,, painting car parts, rebuilding an air compressor, to come inside, with Darwin the Shop Kitty, and find a good video from Dale! And having a beer. Cheers Dale! (compressor rebuild vid, including a mistake that led to an almost catastrophic event) will be up in a couple days or so)
Congratulations on the 400th Dale!! Keep them coming. And another excellent video. That tool was perfect. Beautiful work. And there's a lesson there with OEM parts costs. I don't think it's news to a lot of us. Cheers, Peter.
Thanks Peter, I was happy with the tool. Yes, I'm sure most of us that buy from the OEM realize their stuff is overpriced. It neat to find alternate sources at lower prices and mostly the same or better quality.
Dale: your rant is well-founded and also applies to O-ring seals The Parker company has a very large catalog that lists I think, every O-ring seal known to man and how to measure and size them. There are many materials to choose from. They provide an 800 number for tech assistance. The silicone seals I have used for valve cover gaskets and distributer seals last forever.
Hey John, yes that is another area that is priced out of the park, O-rings....I haven't used Parker, but I will check them out. I normally measure them up and get them from McMaster Carr. Thanks for the source......the more the merrier.
Thanks Dale enjoyed the video. I am a retired GM tech, so this was something new for me. Over the past 48 years I have also found myself making a tool to get the job done. The GM axle shaft swage ring tool looks really close to the tool you made. Because there is many different sizes of axle shafts, you have many to pick from. I am not saying this will replace your tool, but with the bolt together heavy-duty plate you will be halfway there. It would still require the machining of the center hole to fit the crankshaft. Have a good weekend. Don
Thanks Don, yes there is all kinds of other tools out there that can be modified or used as is for other jobs. But sometimes you just have to make a special one, that's where the fun comes in, unless you're in a hurry.....then it's just a hassle. But being retired I choose just to have fun making one. I know you know what I mean. Thanks, buddy and have a great Memorial Day weekend.
Congrats on 400 Dale. Your videos have been so helpful for me getting into the restoration hobby with my CT3. So much knowledge on your channel - keep it up!
Outstanding Dale ! Thankyou for sharing your knowledge with us free of charge I have learned alot from your videos and keep learning, I always look forward to the next one.
I completely agree with you on your rant about OEM fasteners. I believe that all the "big four" use the same hardware, but the pricing is different between brands for the same fastener. Unless it has a special marking or purpose, then local nut and bolt suppliers are the way to go! Now, I can congratulate you on your 400th video! Great work on the crank and awaiting the diagnosis on the one in the bike.
You won't get an argument from me. There is one side cover screw for the Yamaha AT1, CT1 that cost over 10.00 that is just insane. None of our local hardware places have JIS fasteners so I have to order them in, but Grainger has most of them and can get them here in a couple days. Thanks for the congrats, it doesn't seem like there are that many. It's been fun though. Yes, I'm ready to dig into the HS1.
Nice work there Dale! Very informative. Makes me appreciate my engine guy all the more since my hands are not so steady anymore and it allows me more time to work on the rest of the builds. Keep producing the videos and I'll keep watching!
Happy 400th video Dale and congrats on the the tool building success too! You could sell those, I'm sure there are folks out there who would gladly buy them from you and yeah, the price of OEM parts is a real racket. It's the same with cars too. You just have to learn how to source similar quality replacement hardware. Ironically many of which are actually easily found, sometimes at our local hardware stores. Finding solutions, all part of the fun.
Thanks Gigi, yes, I could probably sell them, but no one would want to pay the price because I work too slow. I just like playing with bikes, and sometimes that means making tools or parts........that's what I call fun. We all have to save our money, that means finding alternate sources for some things. You are right, it is amazing how many motorcycle parts I find at the local hardware store, and they don't even know they have motorcycle parts. Cool!
Great video Dale, congratulations on 400 videos. I enjoyed seeing the tool doing its thing. You are right about Yamaha parts, I needed some fastening hardware for the fairing on my TRX850 and they worked out more expensive than gold. Best wishes, Dean.
Thank you, Dean, it really worked well. Yes sir, the small parts are just insane. I probably have a small fortune in hardware...you just can't operate without some on hand.
Well done Mr. Dale, i certainly never feel ripped off when I watch your videos! I would pay $5 for the screw if it had the Yamaha Logo stamped on it or if it was special otherwise ya thats too much
Boy I wish we had one in town. The closest one is in Billings......3 hours away. But they normally get my order here over night if I order in the morning.
ther's a place in ohio called McMaster Carr that has any thing you could ever hope 2 find for someone needing parts that you just can't find any where else when it comes to making your own stuff or repairing things with obsolete parts,, they have a lot of options when it comes 2 bolts and screws, look them up sometime if you don't already know about them,, that seal would have 2 bee in there and in good shape to keep from sucking air from side to side, and if that happend it would not run right, am i right or wrong on this? let me know,,, it makes you wounder who invented this stuff the first time don't it? WOW theres ben a lot of smart people in this world don't ya know,, its mind blowing 2 me, im just an old bluegrass banjo picker, bumfuzzeled all the time about things like this, thanks 4 sharing im glad i went along 4 the ride...
Hey James, yes sir, I use McMaster Carr for lots of my hardware needs. Some folks say it does have effect on carburation, I have to disagree, when you perform a leak down check on a twin two stroke both are done at the same time. The labyrinth seal will not keep low pressure air from going side to side, so it basically equals out. Its primary purpose is to slow the fluid movement side to side.
Congratulations on your 400th video! I am working on an HS1 currently so I'm especially interested in your future videos. I need someone to replace a bent connecting rod. Is that something you could replace for me? I don't have the equipment to fabricate a puller like you did. Thanks
Just curious Dale. Was the Air Force still using TO-33K manuals for their PM systems. Your organized approach to everything reminds me of my days in Lowery AFB at the Air Force PMEL school.
Well not sure specifically Jack. I was an instructor at Lowery AFB for 4 years, but not for the PMEL school, I was a Munitions guy. We still used T.O. manuals, if I remember the 33 tech orders were for test equipment. Air force regulations (AFR) were changed to AFI's (air force instructions) in the 90's, I think. Sorry I haven't even seen any of that stuff for 30 years.
I had a 76 RD400 and I felt like one cylinder was sucking pressure from the other cylinder. I thought maybe the center seals were leaking. So I sold it and told the new owner he would have to take it apart and find new seals.
Most do not seal low pressure air out, only most fluids, when you do a leak down check on a twin, both cylinders are done together. The leak will be at the outer seals, gaskets, or intake.
The ridiculous inflated cost Dale is the reason I quit restoring,I had enough a long time ago and it's their lost when nothing goes out their doors anymore,not mind cause I quit ,many other guys have also quit
Yep, understand, I quit a couple years ago. Just decided to buy the bikes, build them and then sell them out right. That takes the "must get it done" out of the equation. If it gets to be more than I can get for them, you just part them out. Prices are just insane.
Dale, I have a 1971 HS1-B Yamaha Twin Jet like yours, It was a barn find in decent original condition with only 2900 actual miles…….However, it hadn’t been sitting for 40 yrs and everything had dried out and needed replacing. I am now replacing the engine seals and cannot find the special tool to remove the armature. I see you have one and would love to know where you bought it?? Any help would be greatly appreciated. Thank you my name is Charlie. I have been looking for 6 weeks and cannot locate one anywhere. Thank you sir!
Sure, thing Charlie, the one I have is made by K & L the part # is 35-5942 I just checked their 2024 catalog, and it is still listed. The old number was YM-01111, it also fits the RD series Yamaha's 76-79. They show their phone number as 1-800-727-6767 ext. 247 for sales, they are in San Jose Ca. Just to let you know you can use a 10mm X 1.25 bolt if you can't find one. These used to be available on Ebay, but a quick search did not garner one. Good luck with your project.
@@montana2strokeracer Dale, Thank you. I ordered one today. Many thanks. Looking forward to more of your videos. The are very helpful. Excellent content. Have a great day.
Thank you for being there and sharing your experience with us.
Thanks Ron, couldn't do it without everyone out there.
Congratulations on the 400 mark, that's a lot of filming and editing. Thanks for all your hard work and all you share with us. U the man!
Thanks John, it doesn't seem like it's been that long or that many.
Congratulations on your 400th Dale. We've all benefited from your professionalism and passion. Good luck going forward.
Thank you, Graham, thanks for the kind words my friend. Best to folks over in Thailand.

Thank you very much, glad these videos have been of some help. More to come.
400 videos is a great milestone Dale. I've gone back and viewed quite a few since I found your channel. I think the HS1 is a worthy bike for #400 too.
Thanks Doug, and thanks for checking out some of the old ones as bad as they are. I agree, the HS1 is in a prominent spot being the 400th.
Congratulations on your 400th video, I watch them all.
Thanks Jim.
400 videos already? That's amazing and congratulations Sir Dale on this feat. Keep the videos coming and I'm here to watch them all ❤
Thanks buddy
Outstanding Dale ! Thankyou for sharing your knowledge with us free of charge I have learned alot from your videos and keep learning, I always look forward to the next one.
Thank you, Shawn, it's what I do for fun, I am still learning myself.....every day.

Nice work there Dale! Very informative. Makes me appreciate my engine guy all the more since my hands are not so steady anymore and it allows me more time to work on the rest of the builds. Keep producing the videos and I'll keep watching!
Thanks Dave, it's good to have a go to guy. I'm still having fun doing this RUclips thing, but it's the bikes that are the real fun.

Thanks for the video and congratulations on the 400th. I like to use the step on the back of the caliper for measuring the length of screws.
Thanks buddy, good suggestion for measuring screws.
Well done Dale. I’m sure no manufacturer owns a screw factory.
Yeah, I'm sure they don't, it's all outsourced, I'm sure. Just like bearings, seals and O-rings.
Great video Dale, congratulations on 400 videos. I enjoyed seeing the tool doing its thing. You are right about Yamaha parts, I needed some fastening hardware for the fairing on my TRX850 and they worked out more expensive than gold.

Very interesting Dale , I have never seen a twin tore down like this !
Hey John, its been years for me. This one will be a refresher course for me. Lets getter done.
like the A team always said, GOT TO LOVE IT WHEN A PLAN COMES TOGETHER.
Thanks Dale , It is Amazing what they charge for silly OEM parts ! I say Hog Wash to OEM stuff like screws and bolts .
Me too Murray.....Hog Wash!!!
Well done Mr. Dale, i certainly never feel ripped off when I watch your videos! I would pay $5 for the screw if it had the Yamaha Logo stamped on it or if it was special otherwise ya thats too much
Great work! (as usual!)
Thanks buddy
I forgot to mention that I get pretty much all of my hardware from Granger for my builds. There is one here in town about 15 miles down the road.
Boy I wish we had one in town. The closest one is in Billings......3 hours away. But they normally get my order here over night if I order in the morning.
Well it worked great. I got mail today. Thanks brother.

Here
Does anyone know and can help me contact Dale so I can ask him about boring and honing a Husqvarna xc500 cylinder ?
Think I already answered this. dsweger@bresnan.net
I'm sorry I only answer comments a couple times a week. Emails once a week.
So can you ? What was your answer ?
So 25 screws from Yamaha would have cost $146.50. 🤔
Thats insane, got to watch where the money goes these days.

💪💪💪💪💪😓😓😓😓🤩🤩🤩🤩👏👏👏👏
Thank you buddy
congratulation`s Dale your wife was right she told you to do the youtube thing if i remember your first few vid`s.
Yeah, she is a smart cookie. I am enjoying the adventure.
