If someone had told me I would enjoy watching a bloke welding one rusty bit of metal to another one I’d have told them to take themselves off to a dark room and have a good think but here I am loving it.
The Car Wash runs are the real fun. "Nice Beamer." Welding rust to rust never works as the imperfect materials will just leave a weld of bird shit. No adhesion or penetration. Clean like the day it came out of the mill. As far as the "Automatic" transmission that would be a point of context. This model does not have a steering wheel or a Play Station paddle but two levers a clutch brake gas peddle.
4:31 "Because we're going to do some Chieftain drag racing, which I don't think has ever been done before." Spoken like someone who's never talked to soldiers about the sort of shenanigans they get up to!
Always remember my first encounter with the Chieftain on an Exercise in Germany, we had 7 attached to us and 4 broke down on the first night, the screaming sound and smoke was biblical - engrained in my tiny brain forever. Yet another great Vid to watch Mr Hewes - thank you for sharing.
I rather think 'they' were talking off a mark that indicated where the water had got to . The scum that floats on the top of the water leaves a mark so when the water recedes a mark is left indicating where the water got to ( a similar mechanism that shows where the tide got to on a beach). The plimsoll line is more to indicate the ships loading and shows how deep the craft is at any moment.
@@billywindsock9597 Maybe cuz it is not a live broadcast. If it was of course they would have heard you 🙂however I was doing pretty much the same as you, whatever line they were thinking about.
The sound of that chieftain has just taken me back 40 years. My father worked at ROF Leeds all his life. The factory was local , me and my mates would spend our summer holidays watching the tanks going around the test tracks. Shame my father has passed away , his knowledge of the chieftain would have been really useful to you.
I'm in leeds I remember hearing those engines when at work at temple newsam Park....do you remember when occasionally they would be seen going thro Cross gates on the transporter and down Selby Road....👍
To be fair to the L60 engine that people love to slag off... Chieftain was removed from service in 1995, how many of these engines are still kicking after probably not being fully serviced or overhauled since then?
Chieftain drag racing!!! Engineering competence, initiative , humour. You and your guys have got it all. Great Britain may have lost most of its greatness but you alone account for most of the 1% which remains.
Tip: Fuel/Water containers, drill a hole in the top opposite the pour spout, insert a tubeless tire valve stem, remove the schrader valve, screw the cap back on. When you're ready to pour, remove the cap and it will vent without the glug glug glug splashing everywhere mess. I did that to everyone of mine on our farm, 8 in total. Work like a charm!
It is still God damned amazing how y'all removed all that concrete from that engine compartment and the crevices and crannies, welded engine mount hard points back in and got an engine pack fitted back in with linkages and wires and plumbing. Very good of you to give that tank another chance to live.
I love the sound of a Chieftain. Thank you for sharing your work on these fabulous machines. I grew up around these old girls and remember that sound so well.
3 years I spent trying not to be killed or have some vital part of my body ripped off by those things in Germany. Every little thing in them tried to kill you at least 5 times a day. Then the track bashing in sub zero temperatures followed by daily maintenance or some highly trained technicians from the REME would rock up and completely wreck a brand new engine pack I do like watching your videos. Some of my happiest days weren’t the tanks but the blokes you crewed with. I never laughed so much. Thanks for the memories
I worked at the company that made TRP (among others) aerosol sprays. Those can can take a beating, I've had them fall from 2 pallets+ high up. But only if it falls on a magical spot about a foot or less of the floor will it first spray all over your work boots, and then take off like a rocket through the entire isle.

Couple of things to comment on one, I was talking with some tank crew in the 1980's and they were telling me that when Margaret Thatcher reviewed the troops in Germany with the tanks driving past they had 100% redundancy to allow for breakdowns 😂😂. Two, some REME guys were telling me they'd stripped rebuilt an engine because of excessive smoke only for it to be just the same after with new rings, seals and gaskets. Joking they said the next option was towing it onto the range at night and leaving it there. Really enjoy your videos keep up the good work.
New rings in old bore is worse than bedded in rings in old bores. Round rings in oval bores means higher oil consumption and more blue smoke and a complete waste of time and money. Slightly different if rings are seized with corrosion. High mileage do not attempt re-ringing you will most times be disappointed. Rebore oversize piston and rings. Honing helps especially with Polished bores but not worn oval bores.
I was watching the bit about the Goleneye's engine and when the Concrete's engine started, I was amazed, until I realized the engines were not from the same vehicle.
Chieftains are my favorite tank. Built a Tamiya kit of one when I was a child and have loved them ever since. After 23 years in the US Army and spending most of that time on M60 series tanks, I pray that you and your crew happen upon an M60 and do a tear down on it. You would be so thrilled on just how easy it is. Chieftains seem pretty complicated but then again, I've never worked on one either. Loved Jack's shirt by the way!
A bit off topic, but the T34 engine piston gudgeon pins are retained by discs of babbit or white metal instead of circlips because of the risk of steel circlips breaking and scoring the barrels and pistons. This was common in earlier years of primitive metallurgy and lead to rapid engine failure. Your T34 engine videos show they were very well designed by a very clever engineer, using babbit instead of steel clips was correct for a large diesel engine powering a train across the width of a frozen Russia, with stations few and far between. This is what the T34 engine was designed to do.
Brilliant vlog....was a 4th Tankie for 8yrs and aside from the normal stuff like track bashing, engine lifts, suspension spring changes (scary as hell if the holding bolt decided to go it went through the hangar roof to infinity and beyond), worst job ever was changong the fuel bladders at the end off a Med Man 7 in -35 Oc still gives me a chill thinking about it now.
15:15 I think the idea of the collector box is to help balance the pressure in the exhausts and therefore in the cylinders. As opposed to having two separate straight through pipes. There are similar things on motorcycle exhausts.
I can not imagine having to deal with one of these in the Army, to me who served on the M60A1, it just seems so overcomplicated and a real pain in the ass to work on. Not as bad as that damned T-72 but, holy buckets. Well done gentlemen. Wish I could see you at the show.
That basically was the conclusion when the Dutch army tested the Chieftain against the Leopard 1 in 1968. I read the rapport in the Dutch national archives. They ran both vehicles over the summer in an eight week course, aiming to drive both 5000km with the required maintenance in between. Neither reached the target, but the Leopard 1 seriously out classed the Chieftain. The Chieftain had multiple breakdowns in its drivetrain, both engine and transmission. Also suffered from a lot of track wear and constant track tensioning required. They had to tension the tracks at least once every 100km they drove. On top of that, much more maintenance was required. The Chieftain needed about 117 hours of maintenance. Leopard 1 about 33 hours during these eight weeks. And a lot of systems on Chieftain where found to be difficult to access and repair, often requiring higher level maintenance units. For example it would take four hours to replace the engine. And replacing the gun (with an EFC of 120) was a maintenance depot level job that took four to five hours. Leopard 1 meanwhile suffered one transmission failure that seems to have somewhat surprised the German representatives. But it could be easily replaced because Leopard 1 had a power pack that could be swapped. That took about 30 minutes with just a crew of four. Swapping the gun could also be done by the crew, in twenty minutes. Leopard 1 was found to be much more reliable, much easier to maintain with a lot of maintenance and repair being able to be done by the unit. Its main failing was constantly having to replace road wheels and drive sprockets. They burned through four drive sprockets and thirteen road wheels driving about 4500km.
@@dogsnads5634 I disagree with that. The Dutch army didn't only buy the Leopard 1 for its reliability. They mainly did it for the operating doctrine behind the design. The Leopard 1 in a lot of ways, is the ultimate WW2 German Panzer. Its the tank the Panzerwaffe would have loved to have. In the "magical triangle" of manoeuvrability, firepower and armour, well the Germans prioritised it like that. There are a lot more factors in tank design, but those are the most common understood ones. The Germans weren't really interested in optimising their tanks for frontal engagement. To put bluntly, those tend to be fair fights and you can lose those. Losing tends to mean burning to death in a metal box so. The Germans where all about observing the terrain, manoeuvring into an advantageous position and striking when it benefitted them. Being able to stop a frontal hit is appreciated, but not the deciding factor. Not being hit was more important. In the context of the Cold War, that would mean allowing the Soviet tanks to advance, and shooting them in the flanks or rear. You don't need a bigger gun for that. The Dutch army had penetration data for both the L7 and L11. They acknowledged the superiority in penetration of the L11. They also stated that the British had a superior fire control system that would allow a gunner to be on target faster. But they opted for the Leopard 1 because they valued the manoeuvrability more. Also they where finding that the L11 its range advantage against T-55 and T-62 was only a few hundred meters. T-64 wasn't really known in 1968. After seeing the penetration datasheets, I feel they where also right in this. Because I have serious doubts about the L11 its ability to penetrate the frontal armour of a T-64, T-72 etc with the L15 APDS rounds. But both the L7 and L11 will go through the side armour of any Soviet tank (its all 80mm for the hull and a bit more for the turret), without any issue.

It's a Merritt-Brown. The nomenclature defines the system of diff controlled epicyclic drives. The change speed gearbox can be anything as this just alters the speed of the back to back annuli which is the heart of a Merrit-Brown system. It is excellently described in the Centurion manual.
I am hoping next year at armour fest 2025 the chieftain there will be a ride tank and I can have a ride I love all your tool boards mr hewes looks so smart 👍👍🇦🇺
That was a video packed full of interesting and exciting information. Can we please have supervisor ted included in the next .😊 please have more video like that.
There's a company in Ireland called Abbey Seals that I used for years for every kind of seal and they always stocked or eventually sourced something to do the job. 2018 I brought in a seal from a small hydraulic ram. "We don't have it but we've a new CNC machine, we'll make it for you. Will this afternoon be ok?" The seal was more rigid than the original so a little harder to fit. But custom made and replaced back in service same day. I'm sure there are similar companies over there for when you find an oddball like that governor seal. Best of all it cost about the same as factory produced. BTW why didn't you just tip the fuel in via the massive inspection hatch? Super video- thanks.
Nice to see Concrete Cheiftain firing into life . Who needs smoke discharges when you have a L60 engine. The enemy would have said , watch out for the smoke and fire at that 😂. 👍👍👍👍👍👍👍👍
Fantastic video as always that Chieftain start up was super easy not what I was expecting, I’m sure you two will marry them 2 T34 engines together, I’m sure you will have problems but you both have a can do attitude and that will always get the job done.
Great work there , my mate Steve had a job watching them engines self destruct at Woolwich they would run them on all sorts of fluids and see how long they would last . Thanks for sharing your adventures 👍💨💨💨
Don't worry about crunchy knees. It's called crepitus. I think it's nitrogen bubbles popping inside the joints. My right knee's been doing it for about 20 years, and the left joined in a few years ago. They're both still in full working order.

A bit off topic, but the T34 engine piston gudgeon pins are retained by discs of babbit or white metal instead of circlips because of the risk of steel circlips breaking and scoring the barrels and pistons. This was common in earlier years of primitive metallurgy and lead to rapid engine failure. Your T34 engine videos show they were very well designed by a very clever engineer, using babbit instead of steel clips was correct for a large diesel engine powering a train across the width of a frozen Russia, with stations few and far between. This is what the T34 engine was designed to do.
loved all the cans of cosby sauce, these engines are most reliable....
Another chieftain saved Ted ! Good work Joe and Jack great video Chaps !
I had a remote control Tiger tank that fired BB gun pellets , not quite as much fun as your Chieftan but cheaper on fuel ( rechargable battery)
These are the best videos. The explanations of what you're doing are excellent.
Bloody great work 'Ol chap!
Brilliant vlog....was a 4th Tankie for 8yrs and aside from the normal stuff like track bashing, engine lifts, suspension spring changes (scary as hell if the holding bolt decided to go it went through the hangar roof to infinity and beyond), worst job ever was changong the fuel bladders at the end off a Med Man 7 in -35 Oc still gives me a chill thinking about it now.
6:15 - I have always called it a "witness" mark. 👍
Can't wait to see the Chieftain drag racing.
Short & sweet quarter mile . . need a rebuild half way
@@benwinter2420 But the legendary Leyland reliability!
When Elvis Presley was a drafted soldier in the U.S. Army there are rumors that he took part in unofficial after hours tank races.
15:15 I think the idea of the collector box is to help balance the pressure in the exhausts and therefore in the cylinders. As opposed to having two separate straight through pipes. There are similar things on motorcycle exhausts.
Ah the organised chaos that is your lives in full view for breakfast coffee... Artful Bodgers... Regards and respect :)
I can not imagine having to deal with one of these in the Army, to me who served on the M60A1, it just seems so overcomplicated and a real pain in the ass to work on. Not as bad as that damned T-72 but, holy buckets. Well done gentlemen. Wish I could see you at the show.
That basically was the conclusion when the Dutch army tested the Chieftain against the Leopard 1 in 1968. I read the rapport in the Dutch national archives.
They ran both vehicles over the summer in an eight week course, aiming to drive both 5000km with the required maintenance in between.
Neither reached the target, but the Leopard 1 seriously out classed the Chieftain. The Chieftain had multiple breakdowns in its drivetrain, both engine and transmission. Also suffered from a lot of track wear and constant track tensioning required. They had to tension the tracks at least once every 100km they drove. On top of that, much more maintenance was required. The Chieftain needed about 117 hours of maintenance. Leopard 1 about 33 hours during these eight weeks. And a lot of systems on Chieftain where found to be difficult to access and repair, often requiring higher level maintenance units. For example it would take four hours to replace the engine. And replacing the gun (with an EFC of 120) was a maintenance depot level job that took four to five hours.
Leopard 1 meanwhile suffered one transmission failure that seems to have somewhat surprised the German representatives. But it could be easily replaced because Leopard 1 had a power pack that could be swapped. That took about 30 minutes with just a crew of four. Swapping the gun could also be done by the crew, in twenty minutes. Leopard 1 was found to be much more reliable, much easier to maintain with a lot of maintenance and repair being able to be done by the unit. Its main failing was constantly having to replace road wheels and drive sprockets. They burned through four drive sprockets and thirteen road wheels driving about 4500km.
@@DanielWW2interesting stuff 👍
@@DanielWW2 But unfortunately the 105mm gun wouldn't have been much use on the tanks the Soviets were introducing at the time...
@@dogsnads5634 I disagree with that. The Dutch army didn't only buy the Leopard 1 for its reliability. They mainly did it for the operating doctrine behind the design.
The Leopard 1 in a lot of ways, is the ultimate WW2 German Panzer. Its the tank the Panzerwaffe would have loved to have. In the "magical triangle" of manoeuvrability, firepower and armour, well the Germans prioritised it like that. There are a lot more factors in tank design, but those are the most common understood ones.
The Germans weren't really interested in optimising their tanks for frontal engagement. To put bluntly, those tend to be fair fights and you can lose those. Losing tends to mean burning to death in a metal box so. The Germans where all about observing the terrain, manoeuvring into an advantageous position and striking when it benefitted them. Being able to stop a frontal hit is appreciated, but not the deciding factor. Not being hit was more important.
In the context of the Cold War, that would mean allowing the Soviet tanks to advance, and shooting them in the flanks or rear. You don't need a bigger gun for that. The Dutch army had penetration data for both the L7 and L11. They acknowledged the superiority in penetration of the L11. They also stated that the British had a superior fire control system that would allow a gunner to be on target faster. But they opted for the Leopard 1 because they valued the manoeuvrability more. Also they where finding that the L11 its range advantage against T-55 and T-62 was only a few hundred meters. T-64 wasn't really known in 1968.
After seeing the penetration datasheets, I feel they where also right in this. Because I have serious doubts about the L11 its ability to penetrate the frontal armour of a T-64, T-72 etc with the L15 APDS rounds. But both the L7 and L11 will go through the side armour of any Soviet tank (its all 80mm for the hull and a bit more for the turret), without any issue.

It's a Merritt-Brown. The nomenclature defines the system of diff controlled epicyclic drives. The change speed gearbox can be anything as this just alters the speed of the back to back annuli which is the heart of a Merrit-Brown system.
It is excellently described in the Centurion manual.
It was a company that was called self changing gears ltd
As always,good explaining and how it's works😊😊,and they will making 👍
I am hoping next year at armour fest 2025 the chieftain there will be a ride tank and I can have a ride
I love all your tool boards mr hewes looks so smart 👍👍🇦🇺
Love the sound that Chieftain engine makes...:)
You had me at 20K
As a former 2434 …1974 - 1998…RH…….I had to laugh re the engine reliability …🤣🤣….Wonderful videos though. That engine sound…to die for still…..
That was a video packed full of interesting and exciting information.
Can we please have supervisor ted included in the next .😊 please have more video like that.
There's a company in Ireland called Abbey Seals that I used for years for every kind of seal and they always stocked or eventually sourced something to do the job. 2018 I brought in a seal from a small hydraulic ram. "We don't have it but we've a new CNC machine, we'll make it for you. Will this afternoon be ok?" The seal was more rigid than the original so a little harder to fit. But custom made and replaced back in service same day. I'm sure there are similar companies over there for when you find an oddball like that governor seal. Best of all it cost about the same as factory produced.
BTW why didn't you just tip the fuel in via the massive inspection hatch?
Super video- thanks.
Best sound from a tank good old chieftain.never did need smoke dischargers.😂
It defo ain't gonna pass its emissions test. 😂
@@ld8341… Greta has left the chat 😉😉
The smoke helps Wolfgang find you…
@@ld8341 .. Just as long as it pisses Greta off, alls good😉🤣
We all have knowledge of something - glad you chaps know how to liquify concrete... Kudos on the smoke-show eh!
you guys are truly amazing...I'd would consider myself lucky even to be able to touch a tank.. amazing work
I love it. Looking forward to the year I get to buy one.
Luv you guys, you cheer me up, no end. Keep it it up...
Nice to see Concrete Cheiftain firing into life . Who needs smoke discharges when you have a L60 engine. The enemy would have said , watch out for the smoke and fire at that 😂. 👍👍👍👍👍👍👍👍
Thank God I came across this Video. I would never have know about the OMH show. I live 20 mins away. Woot!
The concrete chieftain is how I found the channel. So awesome to see how good it looks now
Brought back some memories, the sound of that engine.
Fantastic video as always that Chieftain start up was super easy not what I was expecting, I’m sure you two will marry them 2 T34 engines together, I’m sure you will have problems but you both have a can do attitude and that will always get the job done.
The tool organisation pleases me greatly
Genius use of the hole in the shackle pin 👌
It sounds like those fuel pipe fittings might be JIC.
Great video as always 👍
Yes! I got that wrong
Amazingly non-eventful start up. Came here for the mayhem and banter, got a solid video of a fresh rebuild/start up. Thanks guys!
When you do the next video on the L60 please show how the 2 crankshafts are tied together to drive the gearbox
Great work there , my mate Steve had a job watching them engines self destruct at Woolwich they would run them on all sorts of fluids and see how long they would last . Thanks for sharing your adventures 👍💨💨💨
Plimsoll line.
Marks in paint from bolt positions are called witness marks.
Always good mate Respect from Oz 🇦🇺
Ted has certainly been busy
Well done guys 👍
Ozone layer be dammed, what a sweet sound that engine makes.
Great. Always keep the spout above the level of the liquid you’re pouring out of your container. That way it won’t glug and make a mess 😁
What a cracking sound to that engine😄
Great idea no wheel clamp easy for parking what's not too like 😅😊
Thank you Ted and his crew. You may be thinking of Load Line or Plimsoll Line on the suck squeeze band blow device.
Congratulations and more time thanks for the videos. Greet from Chile
top job boys sounds bang on thanks for the show cheers
The Clarkson-isms are brilliant
Such a big machine and a simple O - ring gets a big meaning... !! 😮
I love the sound of that diesel engine. Keep up the good work
Great vid, lovely recovery of a concrete disaster!👍🇮🇪, looking forward to the Golden Eye engine job!
A pure pleasure once again, cheers lads 😊❤.

Don't worry about crunchy knees. It's called crepitus. I think it's nitrogen bubbles popping inside the joints. My right knee's been doing it for about 20 years, and the left joined in a few years ago. They're both still in full working order.
You want knee pads in your trousers or you will have to get a bungalow like me.
Crepitus is when two parts of a broken bone rub together, if I remember my first aid training from the last ice age…
W e used to have. Rolls Royce fittings on fire systems offshore. Your system might be a Rolls system which may assist you. I recall the system used was highly complicated to allow rigid coupling of haylon bottles to a rigid system from a rack alignment.
