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

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 👍

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.

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

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

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

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

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

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 😳😂

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

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

Interesting…

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.

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

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

mine has a slight wobble from new 🤨

ill be buying a new one

It's the bearing you have to replace

Is some play normal?

😂😂😂

Throw it away and buy a Milwaukee 😆
