You MUST strip the engine completely to clean the crankshaft sludge trap!!
It’s been rebuilt in the past and that has been removed, I am risking it!
Very foolish move. All the indicators you've seen so far on the "workmanship" indicate that you can't trust it. If they couldn't be bothered to change the rear drive sprocket, I can bet you the sludge trap hasn't been taken care of, and it will prove fatal to the engine, because a full sludge trap starves the big ends of oil. You've gone 6/10ths of the way, do the job right and take care of everything. You know better than this. @@DominicChineas
Agreed. Dom you need to do that job, and also check on the big-ends and mains, because this engine has had someone inside who really didn’t know what they were doing or was completely mechanically irresponsible.
The job you had getting to the gearbox sprocket was a typical Triumph ‘thing’ - also on the unit-construction BSA singles (C15, B40, B44 etc), same design - and a right pain of a job.
When Jon comes to play it’s always good though. Thanks both. Les
I agree clean the sludge trap
Cleaned the trap on my 1961 Thunderbird
It was “rebuilt” very poorly. Nobody would have left that drive sprocket like that.
You’re this deep in, please don’t leave a time bomb for yourself. Remember, you have that fuel tank to live up to!
Having gone that far, you might as well strip the bottom half. For sure there will be something wrong in there with all the lack of maintenance the poor bike has had! 😊
With what you have found so far, the state of that sprocket, one washer out of eight, rounded off valve adjuster nuts etc, wear throughout the top end - It would be foolhardy not to completely split the crankcase to inspect the state of the crank bearings and rod bolts.
You’ve gone this far Dom, you might as well do the rest. You’ll sleep better for it as you’ll know exactly what’s in there!
And it means more videos for us :D
Not spliting the crankcases is like only defusing half a bomb, the other half is just waiting to blow up!
If you've stripped it this far I would definitely take the crank out and clean the sludge trap at least, I can't imagine that its been looked at for a long time and if its blocked (or partially blocked) you will starve the bearings of oil and ruin the crank or worse! Getting the cases apart from where you are now is not that difficult.
You guys light up my Sunday. What a great project. And Dom&John is a great combo. Keep doing this, guys.
Our pleasure!
Same! Look forward to these every Sunday evening.@@DominicChineas
You two really are a fantastic team. I could watch episodes of "John & Dom Take On The World!" all day long. Great tv, honestly. Having a friendship as solid as yours is a real gem and something most people miss out on.
With the state of the top end and the primary as Chris said you MUST strip the entire engine . Good luck. All tools are available.
Please, as someone before has mentioned.
Two words, Sludge Trap. Not checking it could result in a very short lived rebuild, it’s simply not worth leaving, especially due to the wear and previous ham fisted spannering.
Dom you need to check the bottom end of the engine i have made this mistake and it cost as much more to rebuild after the bottom failed. Great to see you and John back in the workshop
You two did make me laugh, when the first puller come out I thought I’ve got one of those, and as the next few come out I thought well I’ve got all of those, I almost had to go into my workshop to check mine was still there. 🤣🤣🤣 I just love the sound when the last puller done the job and popped off . 🥰🥰🤩🤩🤣🤣
Adding my voice to the you Must !
split the cases sludge trap will be full & everything will be worn judging by the state of the top end, put a proper in line filter on when you rebuild it as well
Please check the bottom end and small end bushes. It would be horrible to rebuild the engine and then find that the big ends or main bearings need to be replaced and crankshaft ground. Given the condition of the rest of the motor it would be dangerous to assume that any of the engine is o.k.
Don't bugger about lads , have it down to the bottom , I cut corners on a Goldie once , blew the bloody thing all over the m3 . Never again .
Great video 👍🇬🇧
CLEAN it ALL Dom ! It's amazing what you will find, or wish you had found when it siezes up !
""You know it Makes Sense !""
Besides which I will enjoy seeing you taking it apart and cleaning ALL the Sludge out !
Welcome to the Rebuild Shop where much loved but broken treasures are brought back to life... Fab Stuff Dom & John.
I'm calling it - you'll regret not going deeper while you're there. Good luck though...
You might be right! We will see!
@@DominicChineasyou're weakening!
Thanks again for a great vid. I totally agree with the 'split the crankcase' consensus. Mad not to.......and we get to come along for the ride. I know that's selfish!😂
Looking for inspiration to get into my '69 BSA Starfire, currently 'resting' in the shed.
I think we all need a friend like Honest John! What a legend.
"Aren't we John? Aren't we having fun?" 😂😂
So much fun!
17.40 You will regret not cleaning the slugde trap in the crank and I must say that that is the most wear I have ever seen on a sprocket - WOW!!
Ye the sludge trap in the crank&big ends are imperative to be cleaned & checked out so strip the lot& rebuild,peace of mind in the long run.. Ozzy.
Loving the strip down and rebuild with Dom and John. Absolute gold!
Thank you!
Love watching you guys especially as I am a Triumph guy, I had a new (in 1971) Triumph Tiger 100ss and now I have a 1979 Triumph Bonneville 750 T140E. Yes I am an old fart rider.
I'm having a blast watching you guys carryon. You're on a roll now. No need to stop now.
Alan from North Carolina, USA
Absolutely brilliant, you two dudes are having a ball.
I'm loving these videos, got to give you both a big thank you for making them.
I've got a 67 t90 in a container awaiting attention at some point so you've given me a bit of get up and go , maybe 😅
Dom and John, Firdt of all thank you for allowing us to watch you refurbish a T90, of which I once owned back in the 70's. The second point I think you should split the bottom end, as the condition of the rest is subject. You can sleep better knowing all has been do correctly. Kind Regards Andrew
Great work from you pair. I love how you and the guys around you support each other and persevere. Nothing worth having comes easy and when you blag the parts and put it back together, it will be that combination of determination and seeking the best you can a hive that will see the Tiger pounce back into life. Great video, thanks as always for sharing the journey. W
Love your channel Dom! The highlight of my Sunday evening each week. Now don’t be foolish and get the rest of the engine striped down, you know it’s gonna bite you in the ass if you don’t 😂
Hi Dom,
Great video.
Based on what you've found to date ( and my experience of other things mechanical ) if somebody's used a chisel to do up a nut you have a wreck and MUST strip it totally down. You'll regret not doing so ( I know I have in the past ! ).
Here's to next Sunday; keep up the good work
Entertaining Dom and the clutch is a pain in any old British engine lol
I loved watching you use progressively larger and larger gear pullers! The one that finally worked was so large, it was comical!
The way that hydraulic puller was cranked up was frightening. You should have been warned not to stand in the firing line. I once used a hydraulic puller to remove the offside front hub on a car that was in the kerb on axle stands. When it broke free, the hub and puller finished up in the kerb on the opposite side of the road, about 30 feet away.
you two work so well together, well what we see, and get the job done. Brilliant and thanks.
Thank you very much!
Great video and the journey of fun continues. Why stop, go for the bottom end given the mashed up mechanic work encountered so far who knows the is hiding there? Could there be some Babbitt bearings or maybe silicon seals lurking? Thank you. Cheers lads!!!
I’ve never seen a final drive sprocket with that much wear!
You can bet the bottom end will need some attention. Go on, do a full rebuild!!
Wow that was some strip down. Hope you manage to find some new parts there had been some bodging going on! great video and teamwork. A joy to watch.
As @chrisbland8650 said - pull the bottom end down and clean the sludge trap. You can't take anything on trust.
Reminds me of my high school auto shop project to get my uncle’s motorcycle running. I hope you have more success than I did!
Hello John! Hello Dominic!
Hello Engine😂!!
What a challenge!!
Can't wait next episode!
Oh sorry, Hello Peter!
Another highly entertaining and informative video Dom and Jon. I am way too familiar with that sinking feeling when you open up an engine and find that an unqualified gorilla has been there before you and left carnage lying in wait.
You are a braver man than I in assuming that the bottom end will be OK Dom…. My fear is that the unqualified gorilla has been there before you and left a disaster in waiting.
Based on the hackery you found in this engine, I couldn't stop without splitting the case and doing it right Better to spend a couple of bucks now rather than a big pile of bucks later...
Imagine the bloke who did all the bodge repairs, watching and saying to himself, "yep, I did that..." LOL
Dom I am three quarters of the way though re building a T100 that doesn't seem to have as hard a live as yours and the Sludge Trap was completely blocked so I can only add my voice to urging you to split the cases. You will need a specialist pullers for the Timing sprocket removal and replacement but they are not that expensive and readily available on line. On Michael Wallers You Tube channel he has done a series on a T100 Otter framed Trials bike which also covers the engine build which is well worth a watch. Good luck
You have got to pull the engine apart, 🏍️.
You are 2 thirds to a total strip down and a few more hours (another video or two) will confirm the state of the crank and big ends allowing for an informed decision and more video posts (a selling point for the future) A good clean will ensure that any bits of metal (an old bit of ring and even a washer or two) have gone and no surprises for the bearings and oil galleries. An old engineer told me if you're going to do a job, then do it right and don't cut corners.
I run a Tiger 100A (Energy Transfer Model) for three years and never had such trouble as you have had you are making a Dogs Bollocks of the re build said with respect
Totally agree, should they be allowed to play with spanners, doubt it
When you're in this far, definitely get the bottom end apart and cleaned. In the end, you won't regret that decision
As many people have already said - you have to clean the sludge trap in the crank!
Fantastic watching you guys have “fun”! I love when you and John groan at the same time when something awful is revealed 😂. Perhaps if this is your idea of fun….you both may need to get out more 🤣. Seriously you’re the best guys to watch when you tackle seemingly impossible projects 👍. Can’t wait till next week ❤️👏🏼❤️👏🏼❤️👏🏼❤️
Glad you enjoyed it!
It’s a great series. I would love to have an old Triumph, but without a garage or half your experience I think it would be a struggle.
So this is my adopted Triumph.
I think it’s going quite well for my first time! 😂
Absolutely brilliant! I was watching this and anticipating what you would find next. I even commented about not dropping broken bits of piston ring into the crank case. That bike has clearly had a string of not very careful owners… You had better strip it right down or it will knock like an old donkey engine if the big end bearings are anything like the rest of it.
Agree with the majority here Dom, you need to do a complete strip down. Remember your current engine would be way down on power, which your about to restore to factory. This is going to put more pressure on your big ends etc. etc. Do the smart thing 👍
Impressed you made the 'In no time a' tool it made that job possible.
Hundreds of people will tell you about the sludge trap. And they're right.
However, with it split, you'll then need to measure the crank and cam bushes. And they will be knackered. Then you'll change the main big ends. Then the small ends. And it'll go on. And then you'll be £1000 into it.
But.... It will be worth it. They are a sweet engine when done.
Can't believe that clutch hub came off! Mine snapped in half last week. 😭..
I'm down to split cases now, so I guess a week in front of you boys! Feel free to watch my screwups on my channel. I've left them all in! 😂
With all that work, maybe a rebuilt engine that’s already done is what you need - but where’s the fun in that! Great content as expected.
Loving this series.
Into the valley of death.....admire you sheer bravery and naive adventurous spirit...slight unnerving...onwards!
Thanks for sharing 🇨🇦
You can get Torx or Allen head screw kits to replace all the slotted ones.
Split the cases & check the crank bearings, otherwise you'll end up having to tear it all down again...
How many men does it take to dismantle a bike engine?! Turns out it's 4. 😮 We do love watching these antics, we're cheering you on *always*. (For a bit we thought Jon was going to perform engine surgery without his wind sock!!) 😂
Never without the wind sock!
As said before by others you must strip it down further to get at the sludge trap and looking at the rest of the motors components I'd replace the big end shells too after giving the crank a regrind. It's had a hard life by the looks of it like most of these old Triumph motors. If you don't clean out the sludge trap it can cause oil starvation of the big ends.
Thoroughly check the alternator coils before you close the primary chaincase. Probably worth changing the rectifier/diode kit as those are often ducked. Good luck!
Don't stop without tearing it all down
If the piston rings are broken, there is a good chance bits could have dropped into the crankcase. As many others are saying, every sign says you should really split the cases and check the crank and gearbox etc.
That gearbox sprocket is criminal.
Hi Don, I’m sure you have found him already but if not check out the 5 minutes in the shed channel - Project Triumph Tiger 90 - a great resource for the engine tear down. Enjoying watching you and John as always.
As I think others have said, send for the legend that is Mr Allen Millyard, that would make a great episode/ guest appearance. 👌😎🏍🏍🏍
You need to completely disassemble and send everything out for steam cleaning. You know there will be a ton of sludge and based on everything you've seen so far you know maintenance was never a priority and I'd wager the bearings are all shot. You're in for a penny, might as well go for the whole pound. Great job as always Dom!
Going to be some bike when it’s finished
vapour blast everything :-) i agree with th total stripdown seems pointless otherwise. great content and just keeps getting better.
You HAVE to take the crank out, at least to clear the sludge trap out, or it will seize after the rebuild. Might as well put new big ends in it as well.
Very enjoyable, you have got to strip the bottom end down, if only to clean the sludge trap in the crank, I just bet that's clogged up. If there is no big end play, might just need some new shells, and the debris that is no doubt in the said sludge trap would have scored the big end bearings, best of luck!, cheers Dave
take it all the way down Dom you MUST clean out the sludge trap - a centrifugal filter embedded in the crankshaft - and you will need the special tools to remove/replace the cam pinions..
When is comes to separaating the cases - Im not sure if the 350s are the same as the 650s but beware of the two hidden screws holding the cases together at the tappet block bore, very easy to miss..
and while youre buyin the secial tools get a clutch removal tool for the next rebuild ..great fun sport..I also bidded on this one !!!
Love the laughter ❤ almost more entertaining than the build 😂… almost 🫵🏻
"Aren't we having fun John"...
AREN'T We !!!
He's worth it though Dom.
Now, about that new engine....
You come so far you have to do the crankcase😱🇬🇧🇨🇦🇬🇧
Bold move not to strip that thing completely. Fortune favours the brave 😂
That’s the spirit!
Oh the joys of vintage machines! You've come this far you may as well take a dip into the gearbox and get out the sludge that's inevitably built up, I mean look at the state of the rest of the engine, what makes you think the gearbox is any better?
Brilliant!
Thanks so much!
Get the cover on your circuit board for the electric in your workshop 😂😂😂
I like living on the edge haha
If that engine has been “re-built” properly I’m the proverbial Queen of Sheba..😂
Great video love watching you guys used to love stripping down and rebuilding engines.
The big ends almost certainly need doing too
Hi Dom, listen to us old heads… split the cases, clean everything.
Rocker box in Wrecclesham near Farnham would be worth a visit for all things Triumph, a very old workshop and shop frozen in the 1960s, a time capsule.
agree you must clean sludge trap
My goodness guys, go buy the clutch puller tool. And the cam gear and pinion gear puller tools. You absolutely absolutely need to open up that bottom end. Please.
Do, as well as cleaning the sludge trap, which is a must do with the state of that engine, you may as well change the crank main bearings as well. The big end shells probably need at least looking at also. Do a proper job fella, you'll have piece of mind👍😎
Hi Dom and John, Yes I think the vote is a complete strip down,😅 don't be sorry that you didn't do it 😂 , now the fun starts 😂 All the best Brian 😃
If I had an engine in a condition like that, I'd be doing a Henry Cole and calling for "Millyard!"
Given the condition of the engine I would strip the whole thing down, save a lot of trouble in the long run.
I’ve just been rebuild my works 1961 trials Royal Enfield 350 and found the same 60 years of being taken apart by other people 🤦 satisfying getting back together with all the correct parts
Excellent video guys..that is quite a re build! Great humour...I'm sure you will be riding her soon 🤣🙈!! Ps , can I have a prize for not being negative about the bottom end!! Cheers Steve
Yes you can! The only comment so far! Haha
The man’s a fool who clearly has no idea of the time bomb, aka sludge trap. @@DominicChineas
You both are doing well 🎉
Best place I’ve found for nuts and bolts is Nobbys nuts, I’ve got all mine from there. May be helpful to you
Whilst you have got this far in the tear-down, and found most screw and bolt-heads in a terrible state, i personally would continue to strip her down and replace all bearings; whilst eye-balling the gearbox. You will regret it if you skip on this, .......trust me. Great videos and the highlight to my week, thanks!
We have had the gearbox out and replaced bearings there, that’s all next week!
Thanks Dominic; May I say that I admire your welding and also your go get it attitude; plus your good taste in projects! Cheers from a Brit in Rio, Brazil@@DominicChineas
Probably worth counting the connecting rod bolts just to make sure they are all there? Sure would hate to have on it throw a rod, might be hard to find parts to fix that.
Welding the bracing strut to the frame would be advisable. No use in not welding it. Use a remote canister oil filter after the engine is rebuilt.
Waiting for every next episode, this is entertainment and educational. Thanks both John and Dom ❤
I think I would also do the bottom end. I have heard a number of stories where someone has only rebuilt the top end and then the bottom end fails due to the restored power of the engine. Ask John the number of VW air cooled engines that have failed in this way.
As you've gone this far , you just as well have a look at the gears and crankshaft.
