THE GREAT CHALLENGER 1 PROJECT!! with a not so great start ... 

I used to work on these in Sennelager from 1989 to 1992. Never seen them in such a bad condition. Good luck, you're going to need it.

It's a pity with all those vehicles to repair, that the two of you have to work out in the rain and cold. Why doesn't the boss build you a warm workshop so you can be more productive indoors rather than wading through mud in a field? He must have a couple of bob now he has sold all those vehicles? Everything looks so primitive. But you two are such enthusiastic guys that you still make the video worthwhile to watch.

It's been 10 years that I can think of that the old range heap has been sat there. It had concrete in for ballast last time I seen it. The engine also left to the elements as well for just as long. I was hoping Mr Hewes would have purchased it but alas.

personally (after jet washing the pack and moving it somewhere clean and under cover, preferably warm with lighting) I would remove the injectors/FIP Rack and get some penetrating oil in there - it will also aid to decompress the engine

You probably know already but didn't want to look at all the comments, yes, both starters can work at same time though we never really used to. A toggle switch in dvrs cab, A bank or B bank starter, you would always use A bank (not sure what side that is?!) and only on a cold start would you crank with no fuel pumps on using A bank, then crank on B bank. Back to A bank to crank & then flick pumps on & she would fire up. Always with the APU on & charging... that would be difficult with the pack on the floor!

Bolt the nose cone back on the flywheel housing, select the worst starter motor out of the three, and weld a big 1" drive socket on the bendix/pinion shaft, then use a long 1" drive breaker bar to try turning it over by hand, the mechanical advantage of turning the ring gear might be better than simply trying to lever the teeth up and down with a prybar..

Looking forward to this one. It's a great piece of tank history and deserves to be up and running again. Good luck with it lads 👍

Poor girl 😢

Best cure I've found for stuck engines is to heat transmission fluid and pour it hot down the bores and let it do it's stuff... Best of luck it's going to be a PROJECT!!! Bob

2 starters, b bank was always a pig to get off. Can be started with either or both starters but preferred with both. There were some CR1 prototypes without armour which might explain why it's there... I cut my teeth on these things and I can't wait to watch how you progress with it...

Christ alive, good luck rebuilding that outside. See if you can find a half decent pack while you take that one inside for a full rebuild.

Challenger 1 has been my favorite tank in terms of looks, glad you lads found and got a hold of this one, I look forward to your continued effort on this beauty.

I do love y'alls optimism. I can tell from here, ya, that ain't gonna move. Ya, that is seized. Best of luck!

This is my first time watching your channel, so i don't know what sort of equipment (tools) you have or resources (money), but if at all possible it looks like that engine needs to be completely disassembled and rebuilt. Wishing you the best of luck and looking forward to seeing progress videos.

Might I suggest that you score a tarp to cover the thing and utilise the marvellous de-seizing attributes of diesel. Use it copiously, apply weekly using paintbrush and/or garden spray, chuck half a pint down each cylinder bore and top up as required weekly. Repeat cycle for a month or two before bothering to bugger about much more. It’ll make shifting stuff a great deal easier, prevent you from damaging stuff, and it’s cheaper and as effective as any of the proprietary de-seizing “magic potions.” Kerosene (household heating fuel) isn’t too shabby either but is overall a little less penetrative, though equally fractionally more lubricant, than diesel.

Hi guys I actually build the challenger 2 transmission, so if you guys need any help on that side I’d be more than happy!

YT recomendation win! I adore challys and saw this for sale or something, keen to see where this goes!

Look like a big job but it be nice to see that engine run great video 👍

good luck boys, looking forward to seeing this one come together

Could you not put lengths of threaded bar/long bolts in two of those holes in the flywheel and try levering the engine round.

I thought the Challenger 1s were reserve tanks! That thing could probably still shoot through two T-72Rs!

Hi there . Love the channel. Only recently come aware of it but hell ! 👨🏻‍🔧 Nerdy Don't know if you got any further was wondering ... The gearbox PTO , through two idlers drives off the torque converter which is effectively the input shaft from the engine. Could you uncouple the prop shaft from the fan unit and rig a leaver to rock the engine ? Probably give a ratio of about 4 to 1 . There is a slipper clutch built into the PTO but it might (😂) hold enough to ease her . Also ... That's a challenger 2 transmission unit , albeit an early one. Good luck anyway fellas .

we all know the real Challenger is the british fridge with the 17-pounder!

Definitely looking forward to part two Tanksalot love will surely win the day Every faith it’s going to run 💯👍😎

to think the other week was working on a donkey engine on a pallet on the forklift out the back of the workshop in the sunshine, shirt off, like a perfect holiday for me, had issues getting the starter motor off as well, the three bolts being Allen type, and that third one in the back, you can see the hole with a torch perfectly in line with the starter body, you cannot get a 3/8s drive in there with the socket on the end, so i had to chop one of my 6mm Allen keys up, use the longer side in a 1/4inch drive and 6mm with many extensions to fit the length behind the starter and swear at it to fall out - I WON ! and nobody died - don't you just love problem solving, its just the frustration of hacking tools up to fit that some dumb ass engineer couldn't design right in the first place to give the mechanics a chance to undo things without specialized tools and do the job in faster time i will look at our engine and see if it has a starter, pretty sure its well stripped by now

"Sometimes I feel we brutalize things......", that gentleman got you a sub 😂😂

Give Mr hewes a shout that's what they do look him up mr hewes.

Keep going with it, it will be great to see it run.

Realy a great, massive challange!

It'll be nice to see this tank cleaned up and running. It'll be a crowd pleasers, and one of a kind.

That's guna be a nice tank when restored can't wait to see it

Ive changed an unholy number of those starters with the engine red hot, still easier than changing the starter on a cvrt when its in situ

Nice one lads. Former CR 1 full crewman here. All the best getting that one going again. You clearly love what you do , so go and enjoy yourself .

More of this please! No one on RU-vid is restoring a chally one

Can’t wait to see this tank running!!

Id love to come tiny your work shop up !😮😅

Got your work cut with that one Ashley. Wellsee the old mans letting you crack on with it

Brilliant video Ash, always wondered if challenger ones were in civilian ownership. When was this one produced

Trying to rotate with bruut force an engine that lay decades out in the elements is a recipe for disaster. You are most likely to destroy something. Best corse of action is to visually inspect the cilinders, cam shafts, crank case etc etc.

I would be checking if the starter motors rotating in the same direction. Because they mount on different sides I bet there 'handed'

We used to turn over the engine with a pick handle in the fans!

You need to lift the engine and look in the crankcase...

😎👍

That's NOT a C1, strictly speaking. It's one of the trials vehicles for the MBT80 project that came to nothing.

Without a proper Lad troop and a large logistical chain it’s unlikely that they will ever get the thing up to anywhere near operational reliability. Sadly. They need regular use which is costly even for the army. It’ll break the bank. However The Gue would make a lovely present to Ukraine . They really need generators Having said that Again it’s the spares issue Coventry Climax Originally a boat engine An engineer could make a lovely generator out of that in Ukraine.

There is 2 starters. Abank and B bank

It’s hitting a ring on the top of the cylinder. Add bet

It's so pretty, do you guys get to keep the tank when you're done with it?

Is this for sale?

I thought there was an issue with the armour being classified? Or has it been removed?

Better with both starters

Dip it in a vat of wd40 for 24 hrs ....Will sort it ....

I thought all cr1 got converted to the cr2 im pretty sure the armour was still a secret

Rolls-Royce CV12 / Perkins 3012 - set fire to it, best thing really.

Wang the turret of and fabricate a cab like the driver training tanks so all the family can go along on car crush days

Not a good start but sound like you don't let things bet you 😊

Crap audio

Abysmal working conditions, the state of the bench, the condition of the tools etc etc
