I have this hammer, i used it with long drill bits (maybe i stressed it too much) and now when i use the rotary drill function i can see the the tipping point of the drill bits swirling around. What do you think i need to replace, what can be broken? The hammer function works fine, but as a rotary drill (without hammering swtiched on) i can't make precision holes when the tipping point doesn't stay firm on his axis! Thanks you very much in advance for every suggestion and help!
@@riccardograsselli9465 I think the main tube is bent unfortunately when you buy the parts and fit them it wouldn't be worth doing. I would suggest buying the same model again and keeping the old one for parts or as a back up
I really like this one doc!! Very detailed and helpful. I'm fairly confident that I can do this same repair after watching and learning from you!! Thanks again doc!!
Thank you for your comments and verbal support on every single thing that you did. Especially concerning the sheared crank assembly and proper push back action of piston when the right O-ring was asserted. The replacement items, lubrication links and transcript were also very helpful.
Great job lad..the only thing I would comment on is when you are prying the hammer tube up and out of the case... Keep your hand away from the back end... I have had ones before that have broke the c clip holding the gear and spring on.. it can come out like a bullet... But that was well done and we'll explained... Take care my friend.
Use light grease inside the tube in the sliding parts Heavy grease on the cogs Ebay for the o.ring www.ebay.co.uk/itm/386435103102?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=ctxmdqtptf-&sssrc=4429486&ssuid=cjPn_ZfdQLW&var=&widget_ver=artemis&media=COPY
Very detailed video, thanks Doctor. Just wondering where can I buy a spare 3 pin connector at the bottom of the drill for D25303DH dust extractor? I have checked everywhere but can't find it.
Got the brushed version so while giving it a clean up i checked an seen someone's been in it and the grease looks green, not sure if it's the right stuff but the machine works fine only problem is hammer drill and hammer mode makes a really loud clacking when you pull the trigger more than half way.
@@doctorlefthandthread the insides seemed fine, nothing out of place from what i saw, didn't take the hammer assembly apart though so maybe its in there
I went over to Dean Doherty's channel, but it has been hacked in the last couple of days. I am repairing a 273 which has a broken crank shaft. I might have a problem fixing it as I don't own a bearing press or puller. Any suggestions? Thanks a Million.
Likely the washer down the tube on the striker number 37 or 41 on the parts diagram that's where the issue is www.partshopdirect.co.uk/dewalt-dch273-rotary-hammer-spare-parts-s15448/

Thank you for commenting it all helps
Great. Very helpful video.
That was my intention to make a proper helpful video of this model thanks for your comment
Cheers! 👍
Thank you sir
Just popped back in to let you know your video helped immensely when stripping and rebuilding my hammer drill.
Thank you these comments all help keep me at these repairs and tutorials

Good man Darren thank you
It's always good, and doesn't hurt, to replace O rings, rusty nuts & bolts etc.
That O ring nearly always gives trouble it is usually sensible to replace it when you are in there
Awesome video can I just use synthetic grease for everything and where would I order new o rings ?
Use light grease inside the tube in the sliding parts
Heavy grease on the cogs
Ebay for the o.ring

I can't see a listing for it online
Good video Paul
Thanks Kevin it might help some man out

Is there anything broken in yours the brushed version has the same hammer mechanism?

thank you so much
You are welcome
Any recommendation for ordinary/heavy grease?
Use this on the hammer striker and tube
amzn.to/3MzybMR
And what about the grease for the rest of it?
Where are you based pal do u do repairs I've the same problem
I am Co Tyrone I do repairs for people that ask I still don't refuse much.
My dewalt dch273 is still able to turn, on the hammer setting any idea what the problem is
I think I know whats happening there I will try and make a video tomorrow to show you how it works I will have one open tomorrow
How the mode selection works in a Dewalt DCH273 #doctorlefthandthread #powertool #diyrepair #
Can you use a beef and tomato pot noodle tub?????
Absolutely the parts will taste more of beef though but this will not adversely affect the performance of the drill
Beef and tomato would probably be better for milwaukee
And original curry for a Makita
Koka noodles for parkside 😂😂

The crank shaft is sold as a single item. Dear enough, at £45
I have taken bearings off with a claw hammer or pry with strong flat screwdrivers before but you need to be careful easy to damage them that
It is sometimes I have old ones
My dch273 making horrorable knocking sound on hammering, what will be the problem???
Likely the washer down the tube on the striker number 37 or 41 on the parts diagram that's where the issue is
www.partshopdirect.co.uk/dewalt-dch273-rotary-hammer-spare-parts-s15448/
Thanks a lot.
A large syringe with a little bit of tube on it would make a handy little grease gun
Big syringe is good for that job yes
