- I have several Leyland L60 chieftain tank engines in unknown condition.
Me and Mr Best fire one of them up!
We need to find a suitable engine for "Concrete Chieftain"

As a Student Apprentice at Leyland Motors I’d walk out of Spurrier Works and hear the sound of L60s being developed in the Research Test Centre with a deep roar coming out of the exhaust stacks echoing around the factory buildings - wonderful…
We were developing the multi-fuel capability of the engine which compromised the engine, then the bloody British Army said they didn’t want this.
Based on the Junkers Juno engine concept, the L60 never made the performance of diesel tank engines from Rolls Royce despite performance packages such as “Sun Dance” (if my memory serves me) and it never achieved what it might.
But it was a beautiful engine, and seeing them being produced on the assembly line painted in that glorious duck-egg blue which the army liked their engines (I think as it helped spotting oil leaks!) was a sight one would never forget. Before the British Government forced Leyland Motors to try to save BMC and all our funding was syphoned away slowly bleeding a proud and great British manufacturer to death…
Rumour was it was to prevent people stealing them as they were so obvious in colour.
The "bloody British Army" NEVER wanted the multi fuel capability, it was an edict passed by NATO that was subsequently ignored by all the major western tank producers with the exception of the UK Gov't who were determined to "play the game".
The English Electric (Nee Napier) Deltic was developed from the Napier Culverin which was licence built Junkers Jumo 204.
What a shame we never had micro deltics for heavy road vehicles and tanks.
Were these engines opposed pistons?
@@neilmchardy9061 Yes, 6 cylinders, 12 internally opposed pistons.
Teds' project management skills are on point.
Legend on 4 legs
He's touring the facility and picking up slack.
They probably blame him when someone drops a smelly fart too. Not just when things go wrong with the tanks!
Oh it's a dogs life.
Teds out back tinkering with one of these mart.cummins.com/imagelibrary/data/assetfiles/0058689.pdf
teds ultra lean hydrogen 2 stroke OP is making 1650 HP and 2650 ft-lbs torque and is out in is doghouse machining the billet steel impulse gravity forged roller bearing crankshaft and his OP uses crankcase scavenging with carbon fiber reedvalves and a Silber turbo! he get this HP out of only 8.2l inline 4 and 2.3 HP per lbs engine weight!
Hands down the L60 is one of the best sounding tank engines ever made.
100%
They spin up quick😀
The opposed piston needs a revisit for small auto engines, They have real efficiency advantages.
Sounds alot like a Detroit Diesel. 2 Stroke. .
@@dwainashton7043 well it essentially is like a Detroit two-stroke or any supercharged 2 stroke. Except here the Piston porting is providing the exhaust valve instead of poppet valves in the head. During world war II Fairbanks Morse built crap load of this type for submarines and generators.
I remember in Britain in the 1960’s Commer trucks used to use 2 stroke diesels. You could hear them coming 1/2 a mile away, they made such a beautiful sound people would stop to just listen to the music of that engine trying hard up a hill with a heavy load.
Pure poetry.
Rootes TS3
@@andrewwmacfadyen6958 spot on, I had forgotten that, like an orchestra playing. It was also the fact that compared to other engines of the period the Roots motor sounded high revving.
The Yanks had two stroke diesel trucks as well, called Screaming Jimmys. On open pipes with the exhaust brake system “Jake Brakes” they sound demented. czcams.com/users/shortslqCSExXX60M?si=GdWxKJB2JAgUZeQG
@@andrewwmacfadyen6958 And the later development TS4
I loved them as a kid. You could always see were the parked
The throttle response and high revving big 2 stroke diesels will never cease to sound really weird to my ears!
They don't rev high despite sounding like they do. At 2k rpm a 2-stroke will sound like it's revving at 4k and what not
I mean its a two stroke so its revving half as much as it sounds
@@Torth121 indeed, and it has many cylinders too, so assuming the firing is staggered, it will sound higher rpm than it is, but blimee, it sounds like it rips doesn't it!
@@Torth121 twice the number of exhaust pulses to be exact.
One of the main failure points of the L60, was that Tankies wanting a brisk start would rev up and drive off before the oil had reached the top crank. Otherwise it was a very good engine if treated properly, but as we know, if you wanted to test the durability of anything, give it to a soldier! 😄
I've never heard of a top crank failing on an L60. How common was it?
@@andyt3304 not very
@@scotttait2197 Didn't think so mate. Did 23 years in RTR and can't recall one ever.
@@andyt3304Worked at an Armoured Eng unit, ABRE and AVLaBs, never had an L60 fail, gearboxes on the other hand would. The L60 was pretty much the only thing that worked in them 😂.
Great work, if L60 was crap as they say, how come these guys get them running well ?
Back in the early 1970's I was the Foreman Quality Inspector at Chilcotts Ltd in Madeley, Shropshire where we made the exhaust silencers and manifolds for the Chieftan and a few other military vehicles and boats as well. The Chieftain silencers were bloody huge, they obviously needed them!
Ted as the crane spotter is the best thing.
Ted is the star of the channel. There can be few dogs who ride on vehicles.
I've seen two of these L60's at my mates place. One was ready to be refitted the other undergoing a rebuild. All I could do was stare at them in absolute awe!
The L60 liners were made by Wellworthy LTD at their Weymouth factory. I got involved with material quality control back in the 1970's
what a glorious way for young men to spend their time
That Leyland advert took me back in time! Evoked a lot of memories of my apprentice years.
Hi folks, brilliant video, we were shot peening hundreds of L60 cylinder liners between 1975/80 ish in Derby, apparently to 'close off porosity' and think there was 12 liners per very old wooden box. We had these boxes stacked 4 high and about 10 deep all the time until the next lorry load arrived..
It's good to see Ted supervising the moving of the crane.
Who knows what might have happened otherwise.
We are (as you say) in Ted's world.
Is the engine ULEZ compliant?😊
Might be exempt 😮😮😮
Lmfao
You tell the commander it’s not 😂
@@bradleybatt1401😆😆😆😆😆FSK👊
Great video as always.....really felt the jeopardy when you all thought it would go kaboom....I never doubted your expertise
I'll remember to check the Engine when I go to buy a Chieftain. Great advice!
When I served my apprenticeship i worked on U series Leylands and C range Roll Royces .Those scavenge blowers were a chore to overhaul.We had a big board on the wall with end plate gaskets of various thicknesses and if the blower lasted 3-4 minutes on initial start up,all was OK. a blower seizure wasn't unusual.
And I'm glad to see I'm not the only one belting a stuck rack with a hammer and screw driver..😁
As a technical manager for a pump manufacturer I went to Catterick camp some years back, a new test rig built for testing rebuilt L60 engines wouldn't cool correctly. We checked all the usual stuff and found the pump performance at 50%. Found the impeller half full / chocked with rubble from when they installed the suction tube into the wet well water sump. Pipe bell mouth was too close to the sump bottom which hadn't been cleaned properly before recomissioning and sucked all the debris into the impeller. Warranty declined - bill for our time..
Love the sound of that engine! I have rebuilt many Detroit 2 strokes over the years, from 4-53s to 16v71s, hate living with them but love the reliability and nothing sounds quite like a two stroke diesel on the governor. Nice job Ted, your boys are producing!
It sounds fantastic Love the sounds of a large cubic inch 2 cycle it sounded very crisp and throttle responsive can't wait until you get it installed Just Brilliant
Was literally Just going to say it sounds really well and it's heavenly man, I loves it
That lasted longer than some of the run ups I did!
Shortest run up was 32 seconds! No 3 cylinder, top crank the conrod spun its bearings and the conrod made a bid for freedom out the top!
I read two-stroke and I knew this engine and I had much in common.
That sound awesome. It’s good to see people keeping they’s going.
The BL advert never fails to make me chuckle
So cool that old lump was good after all , what a great sound at full chat, these old British tank engines rock 😂
Good job ted was there or nothing would get done, oh and Adam needs a slap with a spade
Great work. Small thing, try a lapel mic for sound, should sort out your inside versus outside sound issues.
ditto. can't hear a damned thing unless you talk into the fucking mike. when you do talk to the mike the sound's fine.
Are you an American by any chance? You fkers are stone deaf unless it's blaring noise, it seems. Maybe your factory settings are wonky in the US as its a constant complaint. Apologies if you're not a yank (congratulations even) it's just I see the same thing from 'em all the time...
12:41 protip. Get a good reciprocating saw (good in the sense that it has a good speed control, all else can be junk) and take one of the blades and weld a tamper on the end of it, with a relatively soft (but not too soft) rubber end on it. Very good for several purposes, which include moving reluctant components, shaking crud from assemblies and even rattling loose covers that you don't want to mangle up. Found that trick from a yard master who ran a parting business on the side. Really effective.
I love the placement of the fire extinguishers before start up
Ooh the full start up with the camera vibration ❤❤❤❤
That took me far too long to realise Ted was on the crane 😂😂 what a legend he is!
Awesome work. Love the sound of this. It revs so freely...
Your content is spot on. What a pearler of an engine sound....tip top.
guys i love your videos, because they are genuine, and beautifully raw if i dare to say such a thing, don't change a thing! please do keep posting! i love your tenacity and the honesty in volved with filming from your phones, its very important! I'm a 432 guy my self, but i get it !! i love all the "clankies"
Cheers bud
The sound of the engine makes me smile
Loving Ted's taxi.
Excellent. Though you can tell it’s gone a tad chillier. 🥶
Great stuff sounds nicer than anything else I've heard
Lived in Farnham Surrey /Aldershot as a kid late 70,s / early 80,s used to go to the tank ranges and attack chieftain tanks with our catapults ……best days remember a chieftain breaking down and the so reliable Leyland engine being replaced ……thanks for the content guys love the wit keep up the good work….!
Love the sound of the 2 Stroke Diesels .
Love the sound ,, takes me right back to the late 70,s and early 80,s thrashing that engine around Soltau .. those were the days 😎😎
Engine sounds good when rev and very responsive seem to be running well
Gotta love a 2 stroke diesel. I hope that Leyland made them as good as Detroit. The only issue is the oily exhausts that tend to catch fire and become small flame throwers. Pretty cool unless you're standing in front of the exhaust when it ignites.
The Napier deltics had a habit of it too.
I thought that was just the afterburners , don't all of them come with that? 🤣
"I hope that Leyland made them as good as Detroit" .. it's a Leyland .. so eh ... no.
What did Leyland ever make that was good?
The L60 turned out to be unfit for what it was designed for originally, as the MOD added an extra 10ton in weight to the design of the Cheiftain but didn't say anything to the engine manufacturers.
@@JuniorJunison 🤣
I guess it is of sorts, it's definitely burning.
I would run Silkolene Pro 2 SX 2 stroke if i had one of these.
Now that is a glourious sound
Just great and cool! Thanks for sharing!
That was an awesome video. You got that Leyland diesel up and running.
Interesting thanks guys. Had no idea Leyleand had been forward thinking enough to produce something like this. Love the sound of a 2 stroke firing in anger. Top job!
Loving the content boys, that l60 engine sounds great 👍
Awesome to see Ted on that crane.....like a Boss....that he is!
Brilliant.two stroke sounds wicked.
nothing sweeter than the sound of a revving 2 stroke diesel ...
That engine sounds magnificent
Adam, you have rhythm! 👍😀 Joe doesn't appreciate all your many skills, and your method of keeping your fingers warm. 🔥
Loving the dad filming. 80% floor, 70% floor, 60% floor...stand...stand.....in shot....300% engine. Just as it should be.
Superb sounding engine though. As a (supposedly) multi fuel engine, ever tried running one on different fuels?
If my old memory serves me well the 11a is a fully reliability and life improved engine with the same power output as the 13. Apart from a couple of minor sealing mods they are the same engine. That noise takes me back!
It looks like you may have a selection of useful engines there. Mix and match and you might have a few workers. Ted had the correct management action, you do this while I go inside to see to other matters. Always a good project round the corner with these lads.
Incredible. Love Detroit diesels. Didn't know we had such a magnificent engine as the L60 in England. Never heard of it and I am an engine nerd. Subscribed!
Very first time I have seen this engine.
Looks great
From doubt to success, a great video!!
That's a nice fire, noise and smoke maker. 👍😁
Your success rate in getting these engines working again verges on the miraculous at times. I don't know how you do it, but long may it continue.
😊❤❤❤❤😊
Surprised it sounded so good...a beauty.
5:14 Great that that worked, if not, take a oversized nut then weld it to the broken bolt, let the heat sink in, then wiggle wiggle and if it snaps off, new nut and repeat.
i liked how dad cam was getting as far away as possible. you should put that engine in your little crane
As far away and pointed 70% at the ground.
I could see why Ted might not like the noise! A massive engine. It's a good thing you can maneuverer through the crannies Joe.
Brilliant stuff guys!! That engine sounds amazing!!
Best channel I have come across in a while good job boys
I love a good will it start 😂 this was brilliant it sounded mint 👌
Sounds Mint. Cracking job.
That sound 😲
You guys pissed off that sleeping L60 😅
Epic sound, love it!
Great video thanks for sharing
Now that’s a piece of art… great job as always chaps
Awesome work guys. A bag of crap brought back to life. Top work. What chance getting all three running together.
Just noticed Joe regularly does an excellent impression of a Skeksis from the Dark Crystal Hhmmmmmm!
That is glorious, what a sound.
Not knowing anything about these engines, i must say it sounds real nice. Has a simmilar note to it like a GM 2 stroke.
Amazing sounding engine!!
Could make an interesting tractor puller if you fit one in an old Leyland tractor. 🤔
That would be quite impressive.
Brilliant video! Much admiration for both of you in your resilience, perseverence and pranks in getting this 2-stroke beast to start.
I was a Leyland Trucks (Scammell, AEC, Guy etc) apprentice in the 1970's and didn't realise that Leyland were also producing these....
Your video wouldn't look out of place though in a Health & Safety little shop of horrors !!!!!
,
Mr Best is a beast with the old fire extinguisher
Now that sound brings back memories… last posting in Osnabruck germany, posted to 4th Field RA who had AS90, I had a Chieftain ARRV to try to keep up with them…
No CRAARV available?
nice upload
Cheers Jim
Holy jeezas, that sound of raw power 🤩
what a note coming off that keep them coming boys great content.
That sounds bludy good another great video thanks
One great sounding engine!
That would be a very good generator engine in case of a blackout. Greetings from the U.S.
Like seeing that supercharger spinning
Same satisfying
@@MrHewessame but an awfully big scary sucking hole that would take rags and hats and scalps and hands but yes so satisfying to see. Old metal diamond lathe makes great a great rag saver.
Great sound. Seemed to make the camera shake, too! Will be even better to hear it under load. Interesting engine and great to read the comments from those who remember building / using these at the time.
Are they essentially the same as the Detroit's, with the holes in the cylinder walls and gas system plus the blower. Dangar Stu (Dangar Marine) did a good explanation on the Detroit diesel. Be good to know the sim and diff if poss? Cheers!!
Loving the Gatwick express mini crane
Sounds best at idle...well done.
That sound is just mint.
Sounded the absolute bollocks when I started and run, revved really freely!!!! 😀😀👍👍👍
Sounds freaking awesome!!!
These videos are getting addictive!
It MUST have been a good day !! You had a shave !! ADAM is ( sort of ) smiling and the engine didn't blow fireworks out the exhaust BONUS !!
GREAT WORK guys !! that CANT be fun fiddling with nuts and bolts and squashed fingers in the cold !!
Every one loves a good cold rev!
great sound, great engine
that revved nice + clean, i imagine bolting a tank on it will take the edge off
nice to see the fire extinguisher sponsorship fully utilised...
is the oily exhaust a concern, or normal for something made in the 60/70s by leyland
keep up the excellent work chaps
thank you very much for good entertainment. 👍🤗👍🇸🇯
Sounds very sweet.
That thing makes a freakin’ awesome noise. 👀
