Yeah, the sensible thing would be to sell the digger for scrap value then buy one that works. That would be pretty boring though. Much more fun to try to put this one back together.
I own two of these engines, both generator sets in a fishing vessel. They are tough as nails as a rule with the bottom ends especially so. My guess is if someone rebuilt it they may have over stressed a rod bolt that broke, but it's anyone's guess now. If the crank can be saved and the balance shaft boss isn't broke where the drive gear sheared you could patch it and give it a go. Parts are plentiful for those engines so it shouldn't be to hard to get what you need. Arrangement number is the key to getting the right parts as they used those engines in all kinds of things. If you get to putting it back together the balance shafts are a bugger to time as they are driven by the oil pump idler gear and the plate that the pan bolts through and to has alignment bolt holes that you orientate them and the bolts hold them in place with crank at TDC as you install the oil pump. One tooth off and the balance shaft boss will let go. Had that happen when engineer got in a hurry! I'd scrounge up a runner if you are in a hurry, otherwise would be interesting to see your repairs! Enjoy the hell out of watching you resurrect all these different vehicles, thanks!
When I watched one of your videos for the first time, I was a bit worried about the dog. I thought he might get squashed. But then I realised that he wasn't showing indifference, he's just seen it all before. He's like the grizzled combat veteran who ignores the mortar barrage and only takes cover when he really needs to.
To bring it back from the dead would be best - Bores are fine as liners, weld up and reseal water jacket (seen vids on youtube how they do it in India - looks easy with a bit of heat) - They probably have a vid on a crank regrind using a pair of knickers and a sheet of 360 grit wet and dry if you look?
Great video. The two shafts on each side of the engine block are balancer shafts. From memory, they normally spin in the opposite direction to the crank, and at twice crank speed, they are timed along with the camshaft in the timing case. I've been taking keen interest in your diamond T because during ww2, one of my grandfathers drove a diamond T pulling dead tanks off the battlefield to remove the dead men and repair the tanks or Rob it for useful parts.
The more difficult way will always be the most entertaining. Also i like the way Ted had the foresight to get up and move when you where rolling the engine over in the workshop😂 clever boy👍
Wow that’s pretty catastrophic. I think the 2 eccentric cam things may just be balancer shafts. But they Probably won’t compensate for a missing piston though 😂
I wondered about being balancers, too. Seems more likely that just to throw oil about. I don't completely know, but I reckon there are easier ways to distribute oil. Probably piston shrapnel got into the broken cog thing and turned out to be tougher than the cog. Welding the cog onto the shaft might be tricky so you may need a new shaft and poss engaging cog, too?
As much as I would love to watch you rebuild the engine, I understand the value of your efforts come to light on the resale. If I was purchasing a used digger, I would walk right past the one with a welded up block repair. Since you got the digger relatively for free, put a good used engine in it and make great money on the eventual resale. Awesome video Joe! And by the way, we are all learning useful lessons from Ted too! Enjoy the day. 😃👍🏻👍🏻⚙️🛠
At least a piece of timber was used as a cushion! One wonders though how much shock the piston takes when the diesel ignites on the power stroke. Far more than Mr. Hewes twatting a bit of wood I'd wager..
DearJoe, First of all I was a bit surprised that this Caterpillar Excavator has a 4 cylinder turbo engine since I always thought these were equipped with a 6 cylinder. The engine you took out of this machine is far from easy to repair but at the other hand it might be less expensive than an Ebay exchange engine how ever repairing the original engine will take a lot of time with the guarantee she always will fit back into the machine. Personally I’de like to go for the last option. Look forward to your next vlog and send you love from the Netherlands
Rebuilding this engine will be definitely more entertaining for us. There may be more things wrong with it. From every OTHER angle getting a new engine sounds better.
The sloshing shafts are balance shafts, you will have to set/re-time them perfectly "Balance shafts are often used in inline-four engines, to reduce the second-order vibration (a vertical force oscillating at twice the engine RPM) that is inherent in the design of a typical inline-four engine."
I know families are families but I recon you give your Dad a quiet smile! What you want now is to visit that old vehicle emporium in Lincolnshire that has an engine for every occasion parked on its runways. It has a reference on Utube somewhere and probably has a whole engine that might be of reference to you.
Usually watching you rebuild a machine is the best part. However, with this thing, having seen the damage and read through all of the comments, I'd go for a new engine. This is on the basis that you could spend a fair bit of cash and many hours trying to rebuild this monstrosity, and still end up with a wreck. A wreck incapable of anything more than growling at you. In the end you'll do the right thing I'm sure. 😊❤❤😊
Thanks for these interesting videos.. its stuff I would love to do but my bodies too old and broken now to manage.. heartwarming to see how you tackle each task and just keep on rolling..
Well, I never! Ted doesn't trust your forklift skills! You must have scared him on a previous occasion. Who would have thought that was even possible? This motor is completely rebuildable. All it takes is money for a rebuild kit and a couple of nickel welding rods for the window removal job. In the long distant past before mig welders were invented there were tradespeople called welders, long since gone the way of the dinosaur I am afraid 😂 that repaired this sort of thing daily. Some welding techniques from the 50s and 60s still have their place in the world. Look at CEE Australia's video on grader gearbox repair using spray welding! Genius. You too channels are the best u tube viewing about! Cheers and G'day from Tasmania.
@@Morrisonspouchmy Yamaha RD125 LC most definitely needed the one in its engine. I found out how useful it was when I rebuilt it and mis-timed the shaft... aligned it correctly the second time and the bike no longer wanted to try and bounce up and down on its suspension lol. 😂
I think the funny shafts (one of which lost its drive gear) are balancer shafts. Make sure you get them positioned correctly when you put it back together or you'll make things vibrate even worse than normal!
According to eBay here in the US, a block is $3500 and a reman long block (block & head) is $10k. Trying to rebuild it may be the cheapest option depending on parts cost.... Finding a cheap doner would be the best thing - apparently these 3304 engines were used in wheel loaders & forklifts... Depends on how badly you need the excavator bits and what condition they are in.
Having experienced rebuilding engines in the same state as this it always comes down to economics. It is often the cheapest to source a complete replacement engine than to struggle getting parts and machining this one again to be reliable. If it were mine I'd just chuck in a Perkins!
I so enjoy watching you work on these big Diesel engines. The delight I feel in witnessing you being able to smack something with a hammer because it is so robust is so satisfying. The engines I work with have magnesium castings and clearence differences in the shell bearings in microns. They break if you even think about using a blunt instrument.
If you think these are big diesel engines, you might want to hang around your local preserved heritage railway. The group I was in owned three diesel locos, the smallest of which was 1000hp.
I think that deck spacer is because these engines used to be N/A ( or you can get N/A or Turbo models) so to bolt a turbo on it was a cheap fix to reduce the CR
I loved the way Ted took two steps back when you started to tip the engine over. Top safety dog! Think those two rotating half rods might be balance shafts. If you were to rebuild that 4 pot you'd have to replace the oil pump and clean out all the oil galleries, if there is the slightest chance that the engine failed because of an oil system failure. If you don't then it's a waste of money. Put a V8 in it!
If you change engines to a different model, none of your piping will work. You'll be brazing pipe and fittings for 2 months. It's about money...if you can get another 3304 rebuilt vs rebuilding what you have. I see one sleeve, one piston and connecting rod, lower end bearings, and a gasket set. Your 4 cylinder engine was pretty widely used. Parts should be available. BTW, I think that piston was crushed by compressing water. Got to figure out what caused it...that problem is still there.
@@MrHewes No, the big end bolts failed you pulled one of them out of the sump, judging by the condition of the other bearings I.e. look mint, I think it was either incorrectly rebuilt or old bolts used when they should have been renewed.
@@slacko1971 yup. from memory all those bolts are meant to be replaced when rebuilding as they are TTY. if you reuse them, this can happen. they are expensive, so people cheap out.
If it did not have a hole in the block I would say fix this one - we have every confidence that you can do that for the least amount of money. But for it to have any value to anyone put in a new engine in it and I am sure there is some money to be made either renting it out for many years or selling it outright. When you are done building a bomb shelter or a shop with a pit. Cheers Joe🍺
Mr Hewes, long time watcher and subscriber. Listening to you talk about your time.. I think it's more reasonable to get an Ebay engine and put that in it. I think the digger has more issues than just the engine for you to resolve and therefore you can get on with the job of making it and selling it on (or using as you need). The engine looks ok for you to do a TH-cam refurb but to sell on I think it would be a no.
Yes Fix and weld. Didnt someone offer you another dead engine, maybe you can get Con Rod and oil flinger out of it and even block on the cheap (Cost of Diesel to pick it up). I presume the Cat will only be used around the farm and not sold as a bodge it and scarper. See how cheap you can get it functional. Makes it way more interesting. I remember years ago fixing injectors from dead genset with grinding paste and Brake Clean. People fix stuff all over the world with zero budget.
The cog has broken off one of the balance shafts, these are a rotating offset mass to reduce vibrations that would otherwise cause damage, these shafts have to be timed to the crank like a camshaft is timed, running the engine with them with the wrong timming or removed is bad you can watch the engine shake itself to bits
Those two shafts are harmonic balancers. Invented by Fred Lanchester in 1907. Makes a rough 4 cylinder engine run like a slightly less rough 4 cylinder engine. Looks like one got jammed up with the debris and sheared the gear off.
To rebuild that one properly crank , pistons and liners complete gasket kit , balance shafts and timing is critical on them . Try and find second hand motor . Forget putting a 3208 in they are rubbish and it will be impossible to work on in frame . If repowering look for something mechanical between 3.5 and 5 litre 4 cyl Mazda do a good 3.5l 4cyl or izusu . Have fun cheers from Australia
When you think it is oil starvation you should also damage on the crank main bearing / connection rod bearing / cam bearings. What I could see in the video it doesn’t look like that. You should see for your self. Ss mentioned above, fluid compression either in the combustion chamber or in the sump (sump over filled with oil/diesel/water) is good guess. Can you see on the piston damage if the connection rod is pulled out of the piston or pushed in? I know it’s hard to check with such a catastrophic chain of events.
A rough guess just from what I see in the video: Somehow the rod cap let go, so the rod came off the crank. I think this somehow happened on the up stroke, and the cylinder fired with out the big end cap in place. (Or maybe it was hydro lock,, but the cylinder firing seems more likely.) Either the rod cap or the end of the rod flopped to the side and jammed the balancer shaft. This broke the gear off the balancer shaft. The piston came down forcibly with the rod off to the side where it shouldn't have been, and either twisted it around the loose rod, or the rod got banged in the middle by the crank journal, and broke the piston to bits.
I would replace the lump, refurb and paint the whole thing green. The old engine could be a pile of bits in the corner, every shed needs one of them, unless you have one already.
Repair, I fixed up a cat D6 82 a 1968 tractor that was headless in a field for 20 year. Turbo was seized but a gentle nudge and she whistled into life, worked it for a while then sold her to a collector. New liners and head gasket was all she needed.
I'd vote for repairing that engine. After all, your main purpose in life is to entertain your viewers. Thanks! You could do a proper fix on the hole in the block. No, not welding as it's only low pressure - so a large steel washer with a large rubber washer on each side of the hole plus a nut and bolt through them then lashings of sealant. I used that fix when I accidentally drilled through my dishwasher due to a faulty tape measure🤠
Where's the fun in buying a replacement, go for the rebuild better content all round. A wise man once said " He who dears Rodney he who dears" 😊 PS I'd like to thank you guys for turning out such an insightful, informative channel where respect is shown from start to finish never a harsh word said about anyone and all working in perfect harmony. So don't change a thing.😅 great channel. Gary 🇬🇧🇬🇧
Lots of work if ya try to put this motor back together, and no promises, if you can get another motor off of eBay should be the way, save time, if the price is right, we have been here before with the 3304, ya should be able to find one at a fair price, just my thoughts from ya old cowboy buddy in Texas, oh yeah, that project to refloat the Titanic is still looking for a group like you and ya lads, I really think your the ones for the Job!
Good god. That motor is more scrap that machine. You lads do some impressive work getting things working again, but this whole thing looks like it would be better used for spares on a new-used engine.
Used to strip similar and odd that sump fell off. The gaskets we came across almost welded surfaces together. The shells look brand new as when they are new they come with a gray surface that in time reveals a more silver surface. At a guess someone has previously had the sump off and changed the big ends.
Oooh, that's cattled! That was like watching I Do Cars, complete with customer-installed inspection ports, a disconnecting rod & piston McNuggets. Hard to tell, I've no idea how much the parts will cost and you need lots, or there's an unknown V8 off the bay which may or may not be any good too. Tricky.
Piston crumble, al-fresco conrod, turbo el guano and cog-en-pan. What’s not to like? Up and running next Tuesday lunchtime, clouds of smoke, cup of tea, biscuit for Ted. No problem.
I wonder why this engine had such a catastrophic damage. Perhaps it had very bad mantainace such as never having oil change because CAT engines are renowned to be very reliable! But you have to work really hard, good work 👏 👍👍
New con-rod and piston and gasket, should be Ok. That shaft was most likely a dynamic vibration damper, that got a big end caught in it and sheared the teeth off the cog. If you get it running, it also needs two new teeth for the bucket... 😀😀😀
The metal plate in between the block and the head is just a spacer plate. The shafts in the bottom end are balancing shaft turning to reduce vibrations. Try and see if you could get another core engine same as the one you got to get one good running engine. Or you could get a Perkins form a tractor.

Messed up the balancing timing on a Massey Ferguson once. Damn thing tried to leave thru a side wall and it wasn't even in gear.
Bin off both balancer shafts - problem solved.. "You don't need to worry about vibrations..."

Star of the show is Ted. Here's a vote for rebuilding the engine (if you can find a parts donor engine).
ted is the most sensible one in the workshop ! i think he is the safety officer
To bring it back from the dead would be best - Bores are fine as liners, weld up and reseal water jacket (seen vids on youtube how they do it in India - looks easy with a bit of heat) - They probably have a vid on a crank regrind using a pair of knickers and a sheet of 360 grit wet and dry if you look?
Try to fix and weld it. It's just more interesting to watch.😊
A dash of PVA and some Pritt Stick should do the tricn
I'll 2nd that
It's a dead cat. Of course there are maggots inside
Hello Mr Hewes I think the right move for you is to replace the engine and then keep this one for other spares.:)

Love the bit when Ted thought, 'Nah. I think I'll go stand over here!' Clever boy!
It probably went “BOOM” and immediately stopped running so non of the slag circulated through the oil into all the journal bearings or cams.
Love this channel not so work, health and safety just work! Brilliant.
Ted was supervising the gentle engine rotation on the pallet!...if only we knew Ted's thoughts at that moment!.
Thanks Joe, I had to cut out of my Rammstein video for this. I'm back on it, with a fresh beer.
It was like watching CSI on an unfortunate engine.
PS Me Huwes your the master of the understatement.
I would replace the lump, refurb and paint the whole thing green. The old engine could be a pile of bits in the corner, every shed needs one of them, unless you have one already.
Four pistons is a luxury.
Give it the old "farmer fix"
Nothing deters Joe and the team, Ted obviously the Supervisor?
Great content.
Must have been an 'exciting' moment for the operator when that piston failed!. 🤣 Methinks a second hand motor is a go. Nuff said!
🙂
Repair, I fixed up a cat D6 82 a 1968 tractor that was headless in a field for 20 year. Turbo was seized but a gentle nudge and she whistled into life, worked it for a while then sold her to a collector. New liners and head gasket was all she needed.
I'd vote for repairing that engine. After all, your main purpose in life is to entertain your viewers. Thanks! You could do a proper fix on the hole in the block. No, not welding as it's only low pressure - so a large steel washer with a large rubber washer on each side of the hole plus a nut and bolt through them then lashings of sealant. I used that fix when I accidentally drilled through my dishwasher due to a faulty tape measure🤠
Tusen takk for god underholdning 👍🤗👍
wanna see that block being welded up and the old 4 banger fixed
Good work as always
Jim
Was the cab seat discolored by any chance?
The broken shaft in a balancer unit . They contra rotate in relation to the crank & make for a smooth running engine.
2:55 "Why are there maggots?" She nicely summed up the whole rest of the autopsy.
What about a T-34 conversion? A V12 excavator would be a real head turner! Okay terrible mpg but imagine the power.
Where's the fun in buying a replacement, go for the rebuild better content all round. A wise man once said " He who dears Rodney he who dears" 😊 PS I'd like to thank you guys for turning out such an insightful, informative channel where respect is shown from start to finish never a harsh word said about anyone and all working in perfect harmony. So don't change a thing.😅 great channel. Gary 🇬🇧🇬🇧
nothing like a disconnecting rod and piston mcnuggets to make your day
Save the engine Mr.H! A lot more interesting than just replacing it! 🤩👍
Lots of work if ya try to put this motor back together, and no promises, if you can get another motor off of eBay should be the way, save time, if the price is right, we have been here before with the 3304, ya should be able to find one at a fair price, just my thoughts from ya old cowboy buddy in Texas, oh yeah, that project to refloat the Titanic is still looking for a group like you and ya lads, I really think your the ones for the Job!
Good god. That motor is more scrap that machine. You lads do some impressive work getting things working again, but this whole thing looks like it would be better used for spares on a new-used engine.
I think it just needs some Bondo over that hole and some new yellow paint. Great video love Ted he is a star.
I like how the dog goes "fk this" and gets out the way!
Dogs are very intelligent.
Would absolutely love to see you get that engine running again!!
Used to strip similar and odd that sump fell off. The gaskets we came across almost welded surfaces together. The shells look brand new as when they are new they come with a gray surface that in time reveals a more silver surface. At a guess someone has previously had the sump off and changed the big ends.
Fascinating to watch could have been another hour excellent as always really enjoyed 👌
First time i ever saw a Ted remove an excavator engine all on his own! good boy Ted.
Those are balance shifts to reduce the vibration of the engine.
Gotta love that pool stepladder thing, sir hewes!
Oooh, that's cattled! That was like watching I Do Cars, complete with customer-installed inspection ports, a disconnecting rod & piston McNuggets. Hard to tell, I've no idea how much the parts will cost and you need lots, or there's an unknown V8 off the bay which may or may not be any good too. Tricky.
i have the same stanley double knife the one with the box cutter and flip blades i love it i see u have mr hewes etched on ur flip blade,,, nice !!!
that engine must've went out with one hell of a bang 😮
Piston crumble, al-fresco conrod, turbo el guano and cog-en-pan.
What’s not to like?
Up and running next Tuesday lunchtime, clouds of smoke, cup of tea, biscuit for Ted. No problem.
The block has a window in it. You know because the connecting rod wanted to see daylight.
cuckoo clock
The broken shaft is one half of the balancer unit. They contra rotate in relation to the crank & make for a smooth running engine.
I wonder why this engine had such a catastrophic damage. Perhaps it had very bad mantainace such as never having oil change because CAT engines are renowned to be very reliable! But you have to work really hard, good work 👏 👍👍
The dog was like"bro that shit aint right am walking out of here"
Yep it's fixable....if it was in Pakistan Holes welded up parts replacement and it be running end of week... yep iv seen them do it often....
They ace lads
Replace the engine, too much unknowns and the cost can skyrocket very easy. If you ask Ted I think he would agree
New con-rod and piston and gasket, should be Ok. That shaft was most likely a dynamic vibration damper, that got a big end caught in it and sheared the teeth off the cog. If you get it running, it also needs two new teeth for the bucket... 😀😀😀
Three cylinder engines are spot on to support your environmental credibility 😂
Good luck. I enjoy your channel.
They’re harmonic balancer shafts to reduce secondary vibration.
The metal plate in between the block and the head is just a spacer plate. The shafts in the bottom end are balancing shaft turning to reduce vibrations. Try and see if you could get another core engine same as the one you got to get one good running engine. Or you could get a Perkins form a tractor.
Would a Perkins share same bell housings
@@MrHewes They don’t, but it’s a cheaper replacement probably. Shouldn’t be to hard to make it fit somehow xD Good luck love the vids!
Great video! We need more Digger Content
You do whatever makes sense economically. But time may be saved with just a new \ used motor.
Piston McNuggets, yum. The two timed shafts are balance shafts.
I have total faith in your capacity to fix anything.....well sort of 😂
That shaft with the broken gear is a balance shaft. It's critical for removing engine vibrations.
