Broken Chuck Removed and Replaced - Makita DHP453 BHP 453 - Remove and Replace Damaged 

Too much talking, w/out doing anyrhing

Fair play to you for videoing this hassle you had rather than saying " you just have to undo the left hand screw and the chuck screws off" rather than edit the video to the end with the chuck off ans saying "peace of cake " while hiding all the messing around, this is one of those stubborn jobs that we all get in real life. Nice one and fair play

Great job; I would have given up and thrown it through a window long ago, haha!

Great video 😊 my chuck was jammed cloced with a broken drill bit inside. Got very creative with an angle grinder and a drill 👌

I had a similar problem with mine (the screw was not jammed though, but the thread of the chuck itself) and solved it that way: I removed the plastic cover of the chuck and disassembled the gearbox (I was a bit afraid of that but it is actually easier than one would think). After removing several layers of cogwheels, I saw the shaft. I fastened the now stripped chuck in a vice and used a socket spanner to loosen the shaft from the other side. It was tough, but ultimately worked. After that, I reassembled the gearbox and installed the new chuck.

Loved your perseverance and it makes me almost sane as I have the same issue with a Makita drill. Got the LH screw out but cannot get the chuck to budge]. Don’t have a nut splitter so used Dremel w/ cutting wheel and reduced the old chuck by bits. Your video now has me going back at that drill to get a ‘WIN’ -THANKS A WHOLE BUNCH!!

Thanks for this video. I have a Makita DHP451 with a worn-out chuck that I cannot remove. After watching this, it's going to the local agent. If they don't want to do it, I'll be in the market for a nut splitter!

You deserve a pat on the back for persevering with that job. I have to admit I would probably have given up at the point when you discovered the screw was jammed in the chuck. Good to see all your hard work come together at the end. Look forward to more videos.

How do you remove the chuck from a makita when the drill bit and the Jaws are seized shut and won't open? Do I just need to grinder the whole chuck off?

Last time I took a chuck of a had to put 200 degrees of heat eventually 4 hours later I managed to get it off and replace it with a brand new chuck

Put some cutting tool fluid and leave it and then put some heat around it and inside it so hopefully with the heat and penetrating boat won't expand and should come off

My problem is that the chuck that won't loosen from the spindle. With my old drill I managed to get it off with an allen key and a hammer but I can't seem to do the same with my new drill. I tried hammering an allen key as well as manually applying force with extra leverage, but that just seems to rotate the chuck.

I spoke with a professional tool repairer today and he said that often it's just not possible to get the chuck off a cordless drill. He said it's because they can be so powerful that the chuck is effectively locked on and that if you try the 'hitting the alan key in the chuck method' you'd end up bending the spindle.

What a pain in the arse brother! I’m starting along with you after having gotten the screw out from inside the chuck. You gotta love your drill quite a bit to go through one of these repairs!

Pop a slightly pointed red hot rod down the chuck hole for ten seconds or so so you heat the left hand screw head as it's likely set in with a thermoplastic glue .

After careful consideration of the amount of time and effort required to remove my frozen chuck I have decided to forego the project and ordered a replacement Makita 1/2" hammer drill (renewed)l from Amazon. I shall revisit the frozen chuck later with my angle grinder's cutoff wheel when I'm refreshed and ready to take on a new day. If I succeed I shall have two drills and if I do not my junk box will welcome a new addition!

Very entertaining. I would have just bought a new drill... Don't have the same patience.. 😂

almost tossed the makita in the dumpster until I watched your lesson in persistence . THanks for keeping it old school ,

@ShedTV What is the size of the nut splitter tool you used? Is it rusted screw threads and that's the reason for why the screw is completely stuck?

A pack of carling later the screw came out

Did you manage to have a few beers after lol

Amazing, thought I was loosing my mind. Thank you

Kiitos paljon hyvä video. 👍

I have a Makita 8390D which uses the same gearbox as the 453. I watched your video on how to remove the chuck in low gear with a hammer and allen key but no joy In desperation I stripped down the gearbox to get to the back of the chuck and found the drive gear to be the same as a Torx 45 using the last gear plate and a Torx bit socket I put the allen key back in the chuck held it in a vice and unscrewed the chuck.

This video is like a djavu from a week ago, i came as far st to remove the outer shell with thw jaws, i now have an idea of how to remove the rest og the "#"¤%¤ thing. Btw, from where did you buy the replacement chuck? I really enjoyed this video 😂👍 Keep the vids coming.

Hey i did this today. I didn’t have to hammer it though. Put a socket and held it in place with a breaker bar, then spun the drill in reverse. Undid straight away.

OMG very hard job! 😳😬

To loosen the chuck retaining screw i chucked allen wrench in an smacked it counterclockwise , but not full power (that might have obliterated this zip code), just a couple low powered wacks. This evidently took most the tension off that screw, and then it was easy to unscrew it. Before that, it wouldn't budge. If you think about it it makes sense, the normal threaded chuck when struck counterclockwise should relive tension on retainer screw.

I saw no signs of corrosion on any of the screwed components. In your opinion did the drill leave the factory with over tightened components to discourage repairs? Congrats BTW!

Grinding off old chuck way a head

I found this real life video so refreshing. I had the same problem of a broken Makita chuck, watched several instructional videos on how to remove it and how easy it is, all of which ignore the real life situation where the job comes to a stop with the LHT retaining screw refusing to come loose. I notice you removed the circlip - I saw the circlip and wondered, fortunately at this stage I watched your video. Now I know for sure in the short term at least I will have to buy a new drill and best of all I don’t need to feel a failure because I’m buying a new drill because of a broken chuck. Thanks, great video !

10 out of 10 for perserverance !! Thanks for suggesting the link from your other video, got a small job to do tomorrow then it will be in my workshop to try again and see if I can make it work.

Thanks for the great vid enjoyed so subbed😁👍

You know it a bad one when every tool is out and in your way on the bench. Nice job on the struggle. Suggest a pipe wrench with maybe a cheater pipe to remove the bit you cut off instead of the vice grips.

How do you get the metal chuck off, something inside the chuck is bust so it turns but the 3 teeth do not move so no joy with Allen key.

Same problems after short time

How did you get the collar plate out before getting to the split ring? Been 1 year and I still been trying get my damaged chuck replaced

Hello mate, just spent 5 hours doing the same but without a nut splitter so ended up hacksawing it off. Could you please tell me where you got the replacement chuck from as the ones I’ve seen on Amazon and eBay are much dearer. Cheers Mike👍

very nice to see that

@shedTV Thanks for sharing this and showing the struggle not just the final result! Do you buy the broken ones for your personal use, work or to resell? best regards

Well done I had to do exactly the same thing took a while and that was after I got the screw wich came out easy but the thing just wouldn't screw off

6:17 was worth seeing the whole video and the adverts, just to watch a professional do the same thing as I do: ping a circlip off and listen as it ricochets all around the shed. :) . . . I always make a mental note to cover it with a cloth first - but my memory always lets me down. . . . .

i love your nut splitter idea. i need to get one. the chuck screw might be reverse thread, but as with a normal stuck thread, try doing it up. it may help. i wouldnt try starting to unscrew these screws with a screwdriver. i'd start with an impact driver. no, not a cordless tool known by that name but the thing with the exchangeable bits that you hit the end of it with a hammer. if that buggers the screw head then i drill it out. i recently had to remove a broken chuck. i got the screw out but no further. instead of doing the sensible thing and letting the makita repair shop dismantle it to put the special gearbox locker on it, i got the grinder and measuring tools out and carefully ground the entire remnants away. i may have damaged a gearbox by using the hex key in the chuck method on one drill that i dismantled. i may get a repair shop to swap chucks next time before i reach for a bigger hammer.

Es this work on a ryobi

Very helpful.

100% RE TAR DA TION

Why do all makita drill chucks seize? I have a makita that's about 6 months young. It's just seized. I have a cheapo 3year old Aldi drill that's still ok. 😡

why am i impressed, , because i experienced the same thing, , in makita df333dwye, , eats a lot of thought and time, , you are very patient that's good👍👍👍
