How To Repair A DCF887 Dewalt with a wobbly chuck ( Impact driver Anvil Repair )

Full tutorial Repair video to Repair a wobbling chuck caused by anvil wear ( wobble wear ) on Dewalt Impact Driver Dcf887 with explanation of procedure and parts required. Why is my dewalt impact driver wobbling/ hope fully this is the answer

[@Adamfitz93]

My led ring stopped working. Took apart to test it and found I needed a new assembly. That little metal slider for the speed selection fell out and I didn’t see where it came from. Thumbs up to you for showing us 👍

[@doctorlefthandthread]

Thanks that's awesome. I appreciate the comment they all help

[@forestranger312]

Anyone watching these great videos on Dewalt tool repair will come across the same problem if attempting this repair . The anvil replacement WILL improve the wobble but there’s two issues with nose assembly which also cause wobble where the anvil shaft comes through the nose assy it runs through a needle roller bearing and a special yellow dust seal o ring. That bearing can wear as well as the anvil shaft. I’ve searched high and low and can’t find a source for these two Compts. So you would need to buy the complete nose assy. Combined price for all these parts sadly puts this repair over the cost of a new old model driver (if you can find one now) this makes it a throw away item. But if you don’t mind spending £50 - £60 on the parts then go for it. There is a nylon washer inside the nose assy that looks like a steel one, cost £6, well worth buying as it allows play in the shaft assy also which causes wobble as well.

Replacing the anvil will not fix the wobble. You need to replace the nose sub assembly. Part# N439271..

What I did helped but you are correct

[@robertvecchioni3554]

Great video, I intend to repair a similar dewalt and will for sure reference this.

[@doctorlefthandthread]

Glad to be of help I didn't see many good videos of this model on youtube. I thought it may help someone. Thanks for commenting

[@cristianpaulmartinez52]

Thank you, bought a used one yesterday and it’s best to shht this video helped me alot

Thanks for commenting

A serious case of the weeble wobbles lol Nice to see folks trying to fix things rather than throwing it into the rubbish :)

[@doctorlefthandthread]

That's really the heart and soul of my channel, saving things that are normally thrown away is what I like doing. Thanks for your comment 👍

[@fredholmes6284]

A think all impacts hav a bit of the Friday nights about them..(the wobbles) 🤣

[@EdwinDelPilar-o4n]

Why is it that its always cordless type ones being featured in any repairs like this. I want to see the corded types with the same problem being fixed. Thank you.

[@billspradlin9619]

The Wobbling is from the worn out roller bearings inside the NOSE CONE ASM.

[@doctorlefthandthread]

There is one roller bearing in that it's part of the anvil impact mechanism www.mtmc.co.uk/Dewalt-DCF887-Type-10-Impact-Driver-Spare-Parts__p-132341.aspx

[@doctorlefthandthread]

@@billspradlin9619 that's cool thanks

[@hafeezurrahman1000]

Thanks for the tutorial. Where can I buy these parts including the bearing you noted in your comments below?

[@doctorlefthandthread]

The part number for the anvil is N439275 it can be bought on ebay. The bearing is part of the hammer assembly and to my knowledge does not come as a separate part. The full hammer assembly is expensive and may make the fix too expensive. The new anvil does make a difference on its own though.

[@TacticalThib]

I've never seen this video!! Great video very interesting!! The DeWalt impacts have some of the worst tolerance from factory I've fixed a couple and that ring is a bitch 😂 I believe that's the hardest part of the job. Putting it on I found a lot easier I usually clean all the grime and re grease the anvil and give the springs a good cleaning before adding a good high temp grease and check the seal! You don't want it getting warm and pour out because these impact and know to hammer until they burn ❤️‍🔥 I've seen dozens let the magic 🪄 smoke out running higher ah batteries and making holes with spade bits they can't hang I can burn one in less than 5 minutes seriously 😳😂

[@doctorlefthandthread]

Thank you Branden it's an older video it gets steady views I am not surprised smoke those little impact drivers I have begun to realise they are not the best.

[@TacticalThib]

@@doctorlefthandthread I just uploaded a short on my new multi meter and the voltage on a new Milwaukee 5.0

@@TacticalThib that's cool I will check it out brother 👍

Will this part work with the newer Subcompact 1/4” atomic. Dcf850p1

[@doctorlefthandthread]

All wobble from new unless it's really bad I wouldn't consider it worth doing

[@AlexSwan]

mine has a slight wobble from new 🤨

[@doctorlefthandthread]

That is common and it gets worse gradually

[@matthewbruce3472]

This has happened to mine. Looks like too much of a ball ache to have a go myself. To be fair, I'm really disappointed in my newer dewalt kit, there's always something going, or glitching. My old kit lasted for years, seemed bombproof, but the ni cad and ni mhd batteries were crap. I've invested to much in it to change but I wouldn't recommend dewalt now.

[@doctorlefthandthread]

I know what you mean I consider myself a Dewalt fan but I have to admit some of the impact drivers are not standing up to the abuse that maybe the older ones did

[@rick_3.50]

I have the same issue with my 887 I think I will just get the new 850b instead.

[@doctorlefthandthread]

The 850 is a great choice

[@JAYRODDC117]

@@doctorlefthandthread I used this video as reference to attempt to fix my 850's wobble, and it didn't really seem to make any difference. My 850 is about 2.5 months old and gets used for work ~4.5 days a week, so I don't know if it will hold up long term as a daily use tool

[@codyw5799]

@@JAYRODDC117 my 850 took a hard fall. I only have two lights working and a bit of a wobble. Not near as loose as the one in the video. But it still works good.

[@MR70726]

It's the bearing you have to replace

[@doctorlefthandthread]

The anvil took most of the wobble out I suppose the bearing would have finished the job

[@SL-hq5tr]

Which bearing?

[@doctorlefthandthread]

@@SL-hq5tr part of the hammer type assembly between the anvil and the motor it doesn't come as a separate part as far as I know and it might be too expensive to replace that entire part

[@MR70726]

I was actually thinking the bearing where the anvil goes in if it doesn't have a bearing there then you would have to have access to a lathe and make a bushing but then you would have to drill out a bigger hole to put in a bushing

[@diazaa]

The nose cone s.a actually. Will come with bearing installed.

[@christhespark]

Mine wobbled from new so do 3 over lads on site?

[@doctorlefthandthread]

They wobble from new then they get worse steadily as time goes on

[@adriandoc75]

ill be buying a new one

[@ChrisPatrick-q6k]

Is some play normal?

[@doctorlefthandthread]

In Dewalt you will get some play even from new

[@ChrisPatrick-q6k]

@@doctorlefthandthread I've just bought a brand new DCF900, there's a tiny bit of play you can feel but it's very hard to see. It's not been used, but you think that's normal? Thanks again

Throw it away and buy a Milwaukee 😆

It's an option thanks for your comment
