This is far better than any TV program, mainly Cars that go from rust bucket to completion in 5 minutes. Those that are Engineers / keen DIY'ers would rather see every step of the way for restoration and builds - even showing the jobs that can be a nightmare. This series also highlights the number of special tools that you need to do the job right. Keep up the good work.
Cheers :)
Just wanted to say a massive Thank you. Superb series that helped me strip and rebuild my 1965 6T Thunderbird engine top end and rebuild it. The engine started first kick with no leaks and the performance was a huge improvement.
HELLL YEAH! Thats whats up! happy riding.
lots of dormant vintage Triumph 650's out there and with Todd its time to revive an oldy but a goody. Thanks so much Lowbrow Customs and Todd for these great rebuild videos !!
Had to grind off a little bit off the tool to get it to slide through the cam gears. These videos are priceless to do this, having never done it before!
I sure appreciate your videos. With old age, believe me, we start forgetting. The best aid to this condition is watching others do it right whom we trust know what they are talking about. Most of it is still there but it is the little things you mention that I've forgotten that help me remember and clean out the cobwebs from the memory bank. So for me, your videos are therapy to help with memory loss cause ya feel like shit when you can't remember the things ya spent a lifetime learning.
So thanks Doctor Todd. Your time, effort and patience are greatly appreciated.
I had completely forgotten what the the 2 lines on the intake cam gear referenced but when you mentioned them, it all came flooding back so I'm a little bit younger since I watched this video. Thank you and God bless you and yours.
Looks like the pliers work just fine for your removal/install tool. if a fella were to mill some flats into the outer diameter of the tool, and use a wrench...? just an idea. thanks for putting this series together. you're a great instructor! i'm keeping eyes peeled for 650 parts for a build of my own...this series, coupled with the other publications from lowbrow are priceless! can't thank you guys enough for your efforts into keeping more these machines on the roads, than in museums. cheers!
Todd, the timing reassembly was definitely a piece of cake! Thanks for all the vids!
I really enjoy watching these videos. They’ve inspired me to get out in the building and do some wrenching on my old Honda.
Thanks for this series of videos, very helpfull assembling a T140 .
Fantastic, help and info, would have been lost with out your help 😁👍
fantastic please don't make us wait so long for the next parts really enjoying these
Bought one of your companies triumph bobber tanks months back. Awesome custom tank, and I even mirror polished it.
Thanks for this knowledge brotha! I'd probably be having a more difficult time if it not for this.
Your a great teacher Todd👍
🙏
Merry Christmas Todd! Hope all is well. Nice work on the Video!
Awesome as always.Please keep them coming .Your tools I got work great.
Great videos! Very good info and directions. Just one observation here. Always use steady pressure when pulling or pushing on the torque wrench. Jerking, or aggressively pushing on the wrench gives false, under-spec results. Take the time to c-clamp or bolt your stand to the bench, or find a friend to hold the motor so you can torque the fasteners accurately.
Well worth the wait! Keep the videos coming!
Been waiting for this since May :D. Welcome back Todd.
Todd, Wonderful vid! I have an '86 Porsche 951 and the bottom of the oil filter housing has a chamber-reservoir that is part of the oil pump.This reservoir holds an ounce or two of oil - even after you have drained the oil pan. Install a new filter, refit the drain plug and add engine oil. This oil pump reservoir serves to keep the oil pump primed so that it can instantly start pumping oil as soon as the starter turns over the engine. I see that you installed the new oil pump on the 650 engine but do you first prime the pumping cylinders with some motor oil (not thick assy lube)? I have a '69 T120R that my Dad bought in '68 - it still looks new and runs like a scalded dog! But I'm planning a teardown - and you are my teacher!
Finally...thank you...I have being looking forward for this video. 😁
Great videos, I have an engine to do, looking forward to the next one.
Cool
excellent as always
Todd, I must have missed it. Did the two small screws that you took off last before the cases were split go back into the new cases?
could you do a series on the xs650 engine ?
Howdy todd, gonna be starting my rebuild this coming january when my financial aid check clears from school.
was wondering if you can list all the tools ya used in these videos so i can get them all from yalls website.
im pretty sure i got most of it in my shopping cart, but wanna make sure.
your my teacher in this one, bud. im 24 and jumping headfirst into this. thanks for making a great informative series for me to start my first teardown and rebuild in my garage. im building from a 1963 basket i got off someone for 800, and got a clean frame and HD front end.
also i saw ya in ironhorse this month. right on man.
Shoot me an e-mail at todd@lowbrowcustoms.com and I can send you a list of the tools used
DID YOU PUT THE SCREWS ON THE CASE BETWEEN THE CYLINDER BOX MAYBE YOU DID IT AFTER OF BEFORE THIS VIDEO ?
Where have you been Tod? Welcome back cool video!
Working on a T100 and paying attention to the crank seal for timing cover. I think I hear you say the closed end is facing toward the pinion? I see one note in my manual saying open face toward gears. Maybe that is just for the cam? Logic is telling me you would want the open side towards the oil pressure (which is what I think you are saying) so the oil would push into the seal creating a better seal?
Email Todd@lowbrowcustoms.com directly He will be able to guide you in the right direction. - Mikey
Unfortunately I am not calibrated to such light tolerances. I had to purchase a Torque Wrench in Inch lbs. I got so used to working with 1/2" drives and 100 ft.lbs.even a 3/8s drive feels tiny.
Todd, I have absolutely loved this series of videos! You are a saint! I also love that t shirt you are wearing! Do you still make that design? I can't see it on your site but I do want one! Cheers from UK.
That shirt was one of our Bonneville support shirts , we do those once a year in different designs so it is no longer available
Hope the oil in that can was as clean as you were worried about the rest of it.
cool looking forwArd to ten thanks
I’m thinking about becoming a first time vintage triumph owner. Anyone have thoughts or opinions on which would be a better machine, ( late 60s 650 vs early 70s 750 models). Thanx.
Hope you got your bike. I have one and it rides great.
Would a bead of RTV be ok on the timing cover gasket? Both sides?
not really needed, Todd has not had any leaks not using a sealer. There are oil passageways and sealer if overused could be an issue
I noticed you rarely if ever use heat. Any reason not to?
I need the full rebuild, 9,10, 11 etc.....
Help!!!!
Hello; actually many torque values in the Triumph manuals are not accurate (sometimes are wrong in ft lbs and right in kg m) so for the crankshaft pinion nut the manual (for the 750) have it right in kg; translated to ft lbs is 42 )never ever 80 or so check the size and thread of that nut.
Then in the other side; the rotor nut is little smaller so the torque value is 30ftlbs.
For the camshafts is only to tight fully and that is about 20ftlbs. You could go more but there is no point; is LH thread.
Never ever you will see one of the camshafts nuts loose...
Is not necessary to use thread locker.
In any case, you can use a drop of thread locker with the clutch nut and with the crankshaft sludge trap plug (so you do not punch it again---to prevent micro fissures---) and in the flywheel bolt that you removed to clean the trap.
Observation: When using a torque wrench you must apply steady even pressure without jerking the wrench. Jerking gives a false reading, too low..
Where are you located? I have a 68 Triumph Bonneville that I’ve restored but need some expert help.
We are in the Cleveland Ohio area but unfortunately we do not work on any customer bikes I do this as a hobby in my home garage and help customers with technical questions when at the shop
why no sicone on timing cover ?
It is not needed and there are oil passage ways that could possibly be blocked if too much sealer were used .
You need to turn those adjustable plyers around to use them properly. Just sayin'.
Camera not close enough for a lot of this video....more close ups would have made this video more educational
Pro life tip, just hold a magnifying glass up to the screen!
