She's a thing of beauty. Thanks for another great teaching video Todd. Makes me feel good knowing that there are videos out there for the young folks to watch and learn the proper methods, tricks and specs of these, one of the best internal combustion engines ever built.
"Earthshaking is best left to the elderly cause if ya ain't shakin yerself, how can you shake the earth? Old Triumphs and old men just go together."
Old men and old Triumphs, perfect
I hope so because I'm an old man and I'm fixing to overhaul one of those old Triumphs.
Thanks Todd - i have been working and fiddling with a 69 triumph bonneville for the last 5 years. the pushrod tubes were always a mystery to me - the top end gasket set comes with huge variations of o-rings and square o-rings. Now it all makes sense. Turns out i had pushrod tubes from a swap meet that were two very slightly different lengths. I have put the top end on 3x times and just thought the o-ring had not seated on one side. hahahahaha. Now i know there are 6x pushrod tube lengths thanks to the explanation in your video. Thanks so much - this has caused me mysterious issues with my head for the last several years. Also the clarification on the correct assembly of the rocker washers was invaluable. I had read the service bulletin and googled for the picture of correct assembly. Your explanation made it crystal clear. Another thanks. awaiting parts and will have it all together and the mystery leak will be gone forever.
You'll be pleased to know Todd I just got myself a ring filing tool just because of this video
Thanks so much Todd! My 1966 TR6R is now completely disassembled, cases went in yesterday to vapour blast. Bearing etc in the post. Head and barrel away at Seager Engineering in Ipswich, UK. Crank off to be machined next weekend. Then the rebuild! Can't wait! With watching this series of great videos and the DVD by Hughie Hancox, 'Triumph Unit 650' I know my engine will be done right and last for another 50 years! I bought the bike as a non-runner so can't wait to fire the baby up! Todd you are a champ!
Hey, I've watched the entire series of this disassembly and rebuild to date , I have learnt so much about bikes from this alone, thank you for putting in the effort and time to record it!
Now I just need a set of tools, an old bike, service manual and I will give it a go myself...
Inspired fan from Australia!!!
Dear Todd: The teachings covered in your videos are done in a wonderfully didactic way. Effortless even for those who do not have an English Breed. Always keep it that way with that blessedly altruistic spirit. I am grateful to be able to learn and learn teachings that recently had no idea. Maybe one day we can watch the assembly and disassembly of an Ariel Cyclone 650 cc or a B.S.A. A 65. UNTIL!
Thanks very much - I knew about using the hose clamps for ring compressors years ago but thought it was backyard after spending years going on a Snap-On truck. I did not have a ring compressor for a 1970 TR6- I tried the hose clamps (In the backyard) - I could not believe HOW WELL THEY WORKED !!! used them twice so I know it was just not luck. Now I am using HOSE CLAMPS and going to Harbor Freight. After 50 years of pulling wrenches I am still learning, Thanks Todd. Denis from SoCal.
I’ve watched all of these and have thoroughly enjoyed them. Tomorrow I collect my new (to me) 1972 T100R and although it’s the smaller engine the basic architecture and things to look out for will be similar. Amazing that the bottom end hadn’t been apart and yet the sludge trap was clean and the crank journals within tolerance, it must’ve been looked after in the past. Thank you.
Loving this series of videos Todd, they are very helpful and informative, I am in the process of tearing apart and rebuilding a ‘68 motor for my bobber project. Thanks for making them.
I have a Bonneville 1965 650 blue and silver with 4000 arg miles on tires needs some loving my dad was the second owner it had 1000 miles when he bought the last was on the road was 1974 thanks for the videos GODSPEED Brother
Working on a 1967 Triumph Bonneville 650 bobber style and your videos have helped me a great deal as this is my first experience with a motorcycle build.
Hey, im rebuilding a 1970 tr6 for my father it's been in the family since new your videos are brilliant down to every last detail!, Great job, thanks for the info and help👍 regards from Ireland
Excellent series, rebuilding a 750. Thanks for putting it together
This series has been great for me...Thanks Todd. I think I may enjoy this little bike...
Thank you, Todd. I have been building Triumph engines for some years, so am familiar with what you are doing. But it is most helpful to see someone else do it and gain extra tips. Especially the service bulletins and other trivia.
I now use a plastic chopping block cut in half, with horizontal threaded rods to keep the two halves together, either side of the conrods and sitting on the cylinder base studs, when putting barrel over pistons.
Thanks Todd, great stuff.
She is trying to go home without me.
I really enjoy watching your video sir,
Thank you so much matey, i am nailing a mix and match T120 together, and your video is answering all the questions before i can ask.
Greetings from the other side of the pond! Thanks for posting this video, it's the first of yours that I've watched and it's really informative. I have a T140 that I'm fettling, basically the same as the 650's with a few differences here and there so I've found this really helpful. Cheers mate, from the UK!
Still checking back on the videos, thank Todd
Another great video in this series. I have a 77 Bonneville 750 and although they’re not the same motor, the principal of the motors should be basically the same, but different.🤔
Picking up a 1969 Triumph 650 Bonneville next week, mainly the frame, though it looks the the primary and some other parts are there. Price is good, and I wanted a rebuild any way. So finding your videos on this 650 rebuild was great time, appreciate your detail and not assuming we know shit, to make sure everything is covered. Many Thanks.~Pat
Great Video Todd, I've been waiting for it to be released, I love the attention to detail and all the information and tips, I also like how you named the cylinder after Hank Hills guitar! Looking forward to the next part already, might have to give the full playlist a watch again!
Excellent work Todd, looking forward to the gearbox build
martin murphy it’s already filmed just in the middle of editing, may be out next week if not the following. 💪
Can't thank you enough for sharing your knowledge with us. It's much appreciated. Cheers!
I've got new rings and they were already 30 thou end gap... soured my day.
Brilliant video as always👍👍
TODD !...YOU ROCK BRO !...WISH I LIVED CLOSE TO YOU....I KNOW WHERE I WOULD BRING MY 1972 T 120 TO BE WORKED ON...I'M GETTIN LONG IN THE TOOTH SO MOST OF MY WRENCHING DAYS ARE BEHIND ME...THX FOR THE GREAT VID'S....B..K.
Very instructive and entertaining!Wish you did a build video for the Commando . . .
So much great info thanks lowbrow
Excellent series, you are a good teacher!!
Todd these vids have been sooo useful and saved me making costly mistakes. Great job buddy! Thumbs up!
Hi Todd ! Firstly I would like to thank you for your fantastic knowledge of Triumph engines 💪 I have been building and restoring Triumph engines for 45 yrs and have just received a 1971 T140v which had popped the push rods out of the rocker arm balls on the exhaust side ? Hmmm me thinks 🤔 maybe the head was not re tightened after a rebuild and was too loose ? Or just assembled badly! However on further investigation, found that the rocker spindle washer and sprung washer was wrong as you mentioned! And I think the-sprung washer got caught in the rocker arm end cut and held the up when it should be going down and the push rod jumped out ?
I find its a good way to test if clips are all the way in the groove is to try to rotate them. They will only rotate when theyre fully seated in the groove. Usually I use a small screwdriver for that, either on the end of the ring or on one of the "eyes" (if the clip has them).
I use EMGO parts on vintage bikes all the time in my shop. The quality is easily OEM or better, and I've never had a problem with them.
Hey! Thanks for the great video.One can never know too much about correct assembly technique for these old motors. Just a thought,around 11:26 or so,re: driving home the Tappet blocks,it never hurts to place said Blocks in the Freezer for an hour or so before assembly.The reason being the small shrinkage will help facilitate insertion,AND removal for re-positioning,on the off-chance the locator bolt does not align with the blind hole in the Tappet Block on first attempt. Thanks again.
Is there any chance of condensation in turn rust, i would hate to have any water be it just a couple drops on a brand new rebuild. I know I know your should try being me for a day,FML.
Super-Genius I am in complete Awe.
Todd's the best...and he sounds a bit like Jim Henson. Being a child of the 70's (and growing up on The Muppet Show) I find that very soothing. I don't even own an old triumph and I'm enjoying watching this. I plan on getting an old Triumph at some point. I want to know what it would entail to rebuild the engine. What's the purpose of creating some ring end gap on the piston rings? Because it expands a little when it heats up?
I set up both of mine [650T120R"s] 00.001 under specs. Worked fine with a real cautious break-in.
I really enjoy your vids, thanks!
I have my fanasty parts list all tallied up on your website... gonna take me probly a decade to get everything i need for my 70/71 t120. Took me 36 years to finally get a bike of my own on my 1 income budjet with 7 mouths to feed. But now i have it. Needs the motor rebuilt, a tank, seat, new pipes, and all the little things that are worn out (levers, cables, pegs, rubbers, etc). About 1200$ worth of stuff not including the motor. Hopefully by the time my hair is as long as yours, ill have everything i need and can start the build. Any chance youd be willing to send me a care package?? 😎 🤞 🙏
Thankyou for these videos, absolutely chock full of great useful information. Well done sir.
we wish you luck on the build man and glad these vids can help... This free tutorials are worth a ton.. Free extremely informative information is the best care package one could ask for.
this is good stuff looking forward to the next video
Please make more engine build videos! Would be awesome!
What about the two hollow dowels on the inner barrel studs timing side? great video by the way.
excellent as always
naughty Todd....where's your con rod protection on the front crank studs.....I forgive you
I'm going to replace some pushrod seals soon, for the first time. Glad to get the exact number as far as the gap goes. (30 - 40 thousands.) Todd said he didn't want to put a feeler gauge between the head and the cylinder with his freshly sprayed gasket. I'm wondering if I should put it together and check the gap first, THEN go and spray the gasket with copper spray. Or is ok to slip the feeler gauge in there with the sprayed copper gasket? I'd love to only have to do this once... but that's not normally my MO. Usually it's the 2nd time that's a charm.
Be sure you install the rocker spindles with the oiling holes facing 'up'. This allows clearance for the oil to exit the holes to oil the rockers and other parts. If the holes are facing down, the pressure against the bottom of the rockers tends to block the oil holes..
Stagger ring end gaps side to side lined up with piston pin bosses. This keeps sharp end gaps from digging into the cylinder wall.
Todd is the new Hughie Hancox!
I want to see the completed Bike once she's finished.
excellent !
Dude, its Harlan Williams. Swear to God.
...or is it the tube itself that does the actual pushing - yes, I'm new to this!
We dont install those till you secure the motor to the frame and tightened down the rockers, check out episode 13. ruclips.net/video/QkPQje6Bm44/видео.html
Todd, Can you recommend a shop in Los Angeles that does Cylinder head work on 650 heads? Or perhaps in you neck of the woods via shipping.
Back in 1980 I think I used the same head gasket and didn’t know anything about trying to anneal it. Maybe that is why it was the only part on the whole motor that leaked.
I have 1970 model. I only have to take two of the long head bolts out to take it out of the frame
Thank you, very well done. But, where are the push rods?
Given all them correct vs incorrect measures of assembly... Reckon i'd best take them boys down @ Big D Cycle another brisket.
'68 Trophy Sports done up all the way back in 2012 with 13,384 sucessful miles on it to date.
TR6R DU69160. 12618
My push rod tubes have the wedding bands but I find it will not assemble with the extra flat washer,its been a while getting to this stage in the build.....alway a new obstacle in the road.......just going with o rings.....Wait ,just discovered I may of tried using the wrong flat washers.....good day..
Todd, is that the Bobber behind you that this engine is going in? I keep getting sneaky peaks and it looks tasty! Give us a better view please? I'm doing a 66 TR6R Bobber and you have really helped on the engine rebuild. 95% You and 5% Hughie Hancox! :-) Cheers from UK.
Mighty helpful, and well done. Thanks Todd. What hose clamp size are you using?
Todd said hes unsure, we can look it up for you next couple days and see. but we do sell official ones made for the job if you need them in a pinch. www.lowbrowcustoms.com/british-standard-piston-ring-compressor-for-650-c-c-motorcycles-70-75mm.html
A question. You don’t use Locktite on the cylinder nuts?
Did you stagger the ring gaps on the piston or did I miss that ?
he did, just right before he put the jugs on
Hi is it possible to put a 10 stud top end on a 650 bottom end triumph
Heya Todd .. if I could get some i formation from you on where you send your heads out to be done ... I’d like to have some done by someone set up to do and familiar with vintage triumph heads
Thanx
