Caterpillar D4d sprocket puller.

[@PacificNorthwestHillbilly]

that puller was awesome

[@westerntruckandtractorrepa1353]

Yes, it's pretty nice and works on different makes and models.

[@johnmccaughan4195]

The grin on your face when the sprocket popped loose with one hammer blow was a great thing to see.

[@larroland8001]

It is clear you know design ( is like the Lincoln and ton o wire!!!!) The method you use to train your farm…. Outstanding! Please work safe and press on. Your work ethic should be taught throughout America I salute you, SIR.

[@irenesilvers7096]

30 plus years ago I had the unfortunate job of pulling a sprocket off of an 8H, I was struggling with a non-operational press. Had an old timer walk up and said "let me show you something", He dug through our tool box until he found a ball peen hammer he liked, my second to the smallest. 12 ounces of hammer in his hand he started ringing the sprocket around the hub, in 2 minutes max with a nice ringing rhythm going the sprocket jumped and was loose. With respect I have always listened to the old wrench benders. Nice video, always something going on. I use the smallest ball peen to make gaskets.

[@jth1699]

I have seen the same thing when removing bigger propellers- just loosen the big jesus nut a few turns and start ringing it - when you get the correct frequency with the impacts of the hammer the energy from the hammer strikes is cumulative- pretty soon the propeller pops off - now these propellers are usually brass and 4 to 6 feet in diameter... and I have seen them wrap deck cord around the shaft - get the propeller ringing real loud the explode the deck cord and cause the propeller to be dissociated from the taper on the shaft - usually there a couple of old gray haired guys performing these jobs - experience does count ...

[@YeahJustMe]

Yes indeed! Used that trick many a time to pull various things. Definitely a rhythm to it, different sizes of sprockets/gears/pulleys/what have you all seem to take variations in the rhythm.

[@nathankisner8332]

Old timer in our shop said he used dynamite to get the hard sprockets off

[@johnerway7255]

Thanks again Warren allowing us to look over your shoulder. Great teaching, again!

[@richardabbas1509]

This takes me back 35 years, I was the scrawny apprentice task with helping the CAT fitter pull the rear sprockets off a D8, almost broke me trying to lift everything into place , he had done it many times before and when the sprocket banged free I fell over the pump trying to run clear of it😂

[@calumanderson5617]

Don't care if I'm first or last at least I'm watching Warren's video, thank You Warren. 👍

[@thomasstewart9368]

Now that's a sprocket puller. Holy cow!!!! OTC makes some of the best special tools. Sounds like the "price was right" too.

[@thomasbailey8306]

Those Sprockets can be a BEAR too come off. I watch another KZbin Channel that got a 955 Track loader. He used a 20 ton or bigger jack with chain to pull his off. And had to heat the piss out of it. Well when it finally let go. It just missed hitting them. It was loaded ..Wow.. Your getting it all tore down good. Great Video Warren.

[@suzylarry1]

Tony was Warrens good teacher ! you all learn at the same pace on this rig.

[@died4us590]

The size of the tooling to get the job done is just wild. When you are used to fixing stuff on regular car and truck's, it's amazing. I worked for a guy who rented out buses for people and school's to make trips on, I thought putting in starters, and alternators was working with big iron, but that's nothing on this stuff lol. To bad they don't make stuff as good, and wreck everything with def. I imagine they will try and shut all the small outfits down, just from making it illegal to use anything without all the high dollar emissions garbage. Love your video's, God bless ya.

[@airdale2093]

Hello Warren, my dad was a Service Rep. for Allis Chalmers in Montana and North Dakota many years ago. He was really awesome at troubleshooting and I enjoy watching your videos, especially when you work on AC tractors and Gleanors. Brings back a lot of memories of his stories when he would go to dealships and working the harvest caravans. Thanks for all the stories and excellent videos, you are a very impressive mechanic!!

[@ainsleyhenderson4228]

Great to have the help from young Trent,invaluable to you,but mainly for Him,Good bonding,great team work. Now at 61/2 and still buggering things up,Had approached job centre many times,to get a pair of hands and to give some lads a chance in life,but they have never sent a sole,what an offer,and I would have sent them to college also, the company for myself also is invaluable.So their you go.45yrs Experience,Planes,Lotus eng,Cosworth F1,So looks like it's Experience not worth having.Never mind too late to worry now.But I'm still wrenching and swearing lol,Good luck on this new venture.GBYB+Family's.uk Fan.

[@richardhoneywell7411]

Great video Warren looking forward to more videos on the undercarriage rebuild on those Cat's stay safe.

[@philglover2973]

Thanks for your time and consideration Warren excellent video very informative top job top team awesome

[@821ross]

Good to see you have someone interested in learning from you.

[@stuartlockwood9645]

Hi Warren and Trent 😊 that's one hell of a puller, and sounds like a sweet deal you got on the welder and equipment, more power is always good, thanks for the video guys, stay safe, best wishe's to all, Stuart Uk

[@clintsmith559]

I’m from Ohio.We always called them rails. Used to pull sprockets off in the field.Fun to watch the customer jump when they broke loose!

[@Prariedog]

Great video Warren,thanks for sharing.enjoy the stories .have a great day Trent @warren

[@Bodhranarama]

Sounds like you got a pretty solid deal there Warren.

[@rexgexnortowmader5165]

Looks like a Huge Brake Caliper. Trent is getting some good Hands On Training! Thank You

[@rodneymiddleton9624]

Those taper spline press fits can be a bear to get off. Thanks Warren and Trent!

[@terryrogers1025]

Thanks Warren, nice to see how those sprockets get pulled, the pulling equipment seems heavier than the sprocket itself. Nice job

[@zukowski2023]

It's amazing what OTC makes for tooling to help get a job done (when you don't feel like being had in the tool van by "Tommy")..lol. Trent is sure learning volumes and it's nice to be learning right along with your employer at the same time, it helps build a "team work" attitude.. As another poster mentioned, can't wait to see you push those sprockets back on when they are ready.. Stay Safe!

[@HorsleyLandy88]

The new dude is doing well, he is doing stuff that helps without being asked, hard to find good people.

[@jth1699]

Warren - I am a retired master electrician among other things - when you showed a quick view of your service and looked at the number of power feeders I noticed something you need to check - I thought I only saw 2 transformers on the pole - if that is the case you need to check each phase to ground - when you only have 2 transformers the system usually has one leg that is referred to as a wild leg. It will be about 212 volts or some weird voltage to ground - the other 2 legs will be 120 volts to ground ... one clue to this system is when you look at your breaker panel and every 3rd breaker space is open with no breaker in it. If you have this kind of system the high leg can only be used on electric motors - be very careful to not get the high leg on any lighting systems or control circuits... you will let the smoke out of everything. If you dont understand pay the few dollars and have a real electrician check it for you...

[@artbutler6785]

I've seen a lot of stuff burnt up with High Leg Delta. A lot of guys don't check voltage with a meter. That must be why it's referred to as the bastard leg. Good luck and be safe.

[@twistin140]

Thanks Warren.... boy got 2 vids in a row..... your makin my day! Hey hit that like button folks!!

[@rickjohnson1632]

Your definitely doing the “full Monty” to that undercarriage 👍

[@dgequipment3545]

Thanks!! Love the caterpillars 👍🏻

[@henrymichaelwilson8107]

Hello Warren. We recognise that drawing tool you have their. The difference with ours has a hand pump like a porta power pump. It's the best thing out for those type of jobs.

[@edwinhsingmaster9135]

I have a few OTC tools, and always liked the quality. Was surprised to see the hydraulic press in the Northern Nevada train shop was an OTC, and about 16 feet tall!

[@YeahJustMe]

OTC stuff isn't always made in the USA anymore, but I've still had good luck using their newer tools- OTC still seems to be putting in the engineering effort, anyway.

[@1waukesha]

Boy, I remember the first time I was around pulling the sprocket off a D8K, what a hell of a Bang that made! That one was probably put on way too tight as well, we had the pump basically maxed out, and were wailing on it with a sludge to getter to pop. And pop she did! Lol.

[@michaelowen1750]

Check with your power company what voltage and type of 3 phase power you have.. there's Delta and Y... And 208 and 460 for voltage... It takes a different pole transformer for Voltage changes, and if you convert to the higher voltage, you'll need step down transformers to run lights, 220v and 110v stuff like lights and hand tools... Also, check the welding machine- some can be reconfigured from the higher 3 phase voltage to the lower by changing buss bars-

[@dh-_1011]

Some of those old Miller wire welders can be converted to single phase. This shop I used to work for has a huge Miller that was 3-phase and instead of a rotary converter I found some schematics to make it single. Not too much zing was lost from the machines performance. I may still have the schematics, should be close for a Lincoln anyways. Have a nice day Warren and Trent.

[@richardw.foxhall3392]

Warren, check for correct incoming voltage, if not a transformer of the correct size for your intended load (1-2 welders, an air compressor for the shop, etc.). May have to drop a dedicated circuit to a sub panel, with appropriate circuit breakers, and a couple of runs from the panel to boxes on the wall with 3 ph outlets and your in business. I'm just as happy with a voice over as not, and if young man Trent doesn't know how to get the camera and microphones to synch. I bet he knows someone who can.... Good stuff as usual glad you're training up some help.

[@mfc4591]

I stand to be corrected , I think the Cat manual states that when removing you have to give the sprocket a bump.(once under pressure). as you did. I do also think if the sprocket splines are not clean on assembly , you can have difficulty removing the sprocket.(it is rather obvious!)

[@JonDingle]

Great video, very interesting and just shows what respect and friendship can do when it comes to a difficult jobs or times. Top marks all around.

[@jackking5567]

Hydraulic pullers are the best. I was struggling with a large flywheel and borrowed a local farmers hydraulic puller. Shifted it no problem.

[@farmerfuller87]

I miss your heavy equipment videos thanks Warren uk Boston Lincolnshire

[@greglammers9905]

OTC tools, made right here in Owatonna Minnesota. Stones throw from where I used to work before I retired. Good stuff

[@edwardconti9351]

Awsome tool. Would of like to heard it pop love that sound!!

[@nathankisner8332]

Have a few of those OTC puller/press setups at the shop. I've never seen them used.

[@westerntruckandtractorrepa1353]

Really, it's a nice setup.

[@dozer1642]

“Ain’t much of a video.” Lol, love your content my friend. ✌️🇺🇸👍

[@keithglover1001]

That’s one big ass sprocket puller. Pretty cool.

[@steveasher9440]

You can build a rotary phase converter to run your 3 phase welder pretty simple. Just look it up

[@billysmith6131]

That is an impressive tool. Good thing to have in the shop or tool box....if you'd use it enough.......hell even if ya used it 1 time a year. Very handy!!!!

[@tomgraham2987]

Hey Warren, here in the South we call them rails also. I don’t think I’ve ever heard them called any thing else.

[@Dan.Whiteford]

That sure is one mighty heavy puller which is clearly very effective but I really would like to see how it is used to push that sprocket back on again.

[@clintsmith559]

It doesn’t.

[@michaelmcclure8673]

That tool looks like a giant 3 jaw steering wheel puller. 😳

[@cineminded]

Goodmorning USA , just watching this video before work, a perfect start of the day .

[@joeclarke9782]

Very very neat operation.

[@tracydiller9378]

OTC makes some very nice special tools i have a number of them at a good price.

[@andrewcerto6572]

that’s amazing, love to see you learning and teaching us as well. and yes, they’re track chains.

[@williamhoward8319]

have used portapower many times in the mine pulling bearings and large sprockets

[@johnwaby4321]

The job sure goes great when you havd the right tools 👍👍👍👍👍

[@mongomay1]

Warren, that power pole looks like single phase. You should have 4 current carrying conductors for three phase (A, B, C, neutral line and ground tap) for delta or wye configuration. Three will be 3 power fuses for three phase and only one power fuse for single phase. Get in contact with your Utility electrical engineer and ask, most I have met are helpful folks that are under appreciated.

[@dzrdr65]

Waren, Correct me if I am wrong but I am seeing 2 ports on that cylinder which would make it a double acting cylinder. Thus the pump should be a 2 line pump to push and pull. I have the cat version 2 line pump for a thru center ram and if I do not have the second line engaged properly the ram will blow the pressure relief due to high pressure on the second side of the cylinder. Hook up both lines so the second side can relive to tank.

[@johnbehnke1873]

I noticed that too… My puller has a double acting cylinder

[@heavydutyrepair64]

Warren ,the old otc /wtc track press ram looks jost like that 100 ton ram,all you need is the c frame & bolts

[@heavymachinery2843]

Awesome love that puller i need tools like that one day Awesome stuff yeah the old wrench benders know how to get shit done good Video warren 👍👍

[@harrykeel8557]

I have two manuals one a operating and maintenance book for serial numbers 6u1-up and7u1-up. Also the one Daddy had, had a Traxcavaror loader mounted on it. And I have that twelve page installation booklet. Do you need these books, as I have no use for them, and they might be helpful for you or someone else who still uses one. Every time you work on a old D-4 it reminds me of being a kid a growing up in the sixties. In fact when I see a big CAT, it reminds me of better days. Stay safe Sir, and have a blessed day.

[@kwshilts]

Good people helping good people. Just the way it should be done.

[@alansmith4734]

Impressive! I'd love to see how you press the Sprocket back on!

[@michaelparker5814]

That's a case of right tool for the job nice vid 😁

[@seanfoxx4761]

Not sure you have three-phase, go back out and make sure there are three TRANSFORMERS. Your breaker box will have three blacks coming in and might have colored tape on them (brown, orange, yellow for 480) and then three bars coming down inside the box instead of two. Good luck!

[@joestreiff9401]

I'm no track undercarriage expert, but those sprockets looked like they've seen better days. I'm thinking there's a lot of slop in them.

[@brettgoodman4360]

Looks like you have 3 pots on that pole so you should have 480 volt 3 phase available.

[@popswrench2]

i have been FORTUNATE to have changed more than a few and ALL bolt on and many segmented , komatsu . but back then , all were press-on/off except little antiques . D21/31/37

[@fire44x]

Thats a heavy tool but its sorted great work

[@markreetz1001]

That's a slick tool, Warren. You looked pretty relieved and happy when that wheel popped off with the hammer strike! Might be something wrong with that rear drive sprocket. I don't think the teeth are supposed to be that sharp? Good work!

[@pootthatbak2578]

Somebody stopping in here, not knowing you, may think youre an amateur. NOPE. You are a pro, you may not have touched that many d4s, its not like you worked at a CAT dealer only for 20 years before this. There exists 1000s of different machines. The problem with capitalism is that americans have bought and had access to a large variety of machinery. There isnt much stuff that is standard. Im proud how you take on all comers and learn as you go. Theres no stopping a independent, hard working business man.

[@elroyelblander6277]

👍👍kick ass tool man... could use one of those over here... probably a little expensive to buy new,...lot of those things are,but anyway... another great video 👍👍

[@paulcrocker2837]

[@williamfocha5168]

If you don't have 3 phase you can get a 3 phase converter from most wood shop tool suppliers

[@JD-zm4eh]

Steering wheel pullers shudder in this pullers presence.

[@blake9361]

good vid warren

[@kenmccormick3052]

most power lines coming into structures are three wire.

[@TimberTramp]

Don’t break it, but accidents do happen….usually with borrowed stuff. But for anyone listening, something I was taught about borrowing tooling, clean them up before returning, treat them well, and a good rule of thumb is to-- ‘return your borrowed item in better condition then when you got it’--

[@commenter5469]

Yep! Three transformers on the pole - three phase is there.

[@edneialmeida7612]

Boa noite muito top serviço dessa máquina meu amigo

[@38365chevelless]

Hi Warren, I was just wondering if they make a hub that takes segments for the d4 d,you could save yourself a lot of work. You are a worker, wished I lived closer, but I am worn out 70 yr old Cat Mechanic, please take take care of yourself, 😎

[@mikecopenhaver4484]

Theys Jumpin on the Band Wagon, eh. Don’t stop!!!

[@andregagnon7044]

you can buy a box to add the 3rd phase

[@steamboat1341]

Could you make a mobile phase converter, if anyone you could.

[@AmericanaStoryTeller]

One question. What are these D4's setup to do? It looks like some kind of auxillary unit on the forward right fendor.

[@israelfontanez615]

man that is some puller.

[@jamesm9766]

So that tool will press the sprocket on also

[@brianrutherford3681]

Very cool puller tool.am I wrong in seeing the sprocket is shot.it looks to me to be way way to pointed on the teeth.

[@archangel729]

🚨That is a cool tool🚨 definitely worth it to purchase but make sure you eat your wheaties 💪👍👀lol and thake you for dubing over . Until the next video peaceout

[@duanecreativemachine]

They say you can't hear a picture but I swear I could hear that sprocket hit the floor lol

[@frank4532]

Great video Thanks for sharing 👍

[@semistop8594]

Warren, this doesn't really apply to this video, but have you thought about making a truck tour video of your service truck? Kind of like a tool box tour.

[@grumpyg9350]

Fun to watch

[@billbooth4147]

Well dang I’m from the hillbilly always called them and been told they were rails

[@genechronister7085]

Nice vid!

[@darrenlewis7001]

Just because there's three legs coming in doesn't mean it's three phase. If I remember right 3 phase is 3 hot legs and a neutral so it would be 4 legs coming in. You need to check with the power company or an electrician

[@westerntruckandtractorrepa1353]

There's 3 transformers there so it's 3 phase.

[@joezaloga]

Before you go with 3 ph power check if you have to use a demand electrical meter your electric bill will cost a Fortune if you do

[@texasgilley9533]

Very educational enjoy the video

[@jake2213b]

I don't think you have 3 phase run to that building. BUT it looks like the you have 3 phase on the electric pole on the street.

[@corywillbanks6348]

Cat SIS says install sprocket with 20-25 tons of force. If you need any help with specs or instructions let me know and I can look it up for you. Edit just got to the part where you stated the install spec never mind lol. My offer still stands though.
