How to repair a Dewalt 18v DCH273 SDS drill that is no longer hammering.

This dewalt sds drill, the DCH273 is supplied with very little grease inside. After a few years of work, the piston and striker can become dry inside and wear out.
The repair is quite easy but getting into the piston can be headache.

Thanks for posting these vids. Usually work on Paslode nailers but my son brought one of these Dewalts home from work and asked me to try to repair. Couldn’t have done it without you👍

What grease should we use

[@user-iq5cp3vl8d]

True . Built to fail and be replaced. Their double battery mitre saw is a joke . Just blows motor after motor

When he started disassembling and throwing screws around, I thought this guy is messy and unprofessional. Wow, he really knows his stuff and very sufficient. 👍

And have you ever come across these with a symptom like it is hammering too hard really loud hammering and if you have what did you find was the problem

Im thankfully with this guy, I was able to fix my hammer drill, one of the pieces was Broken, I replaced it and I didn’t have to buy a new one, thank you so much

Well done my man but if only parts were that fast to get.

Bosch 18v sds is the best by far

Hello Dean what brand grease u use in dewalt sds gearbox

[@ace1rtp]

Just wanted to say a huge thank you. stumbled on this video by accident this morning as i was just having a look through TH-cam and I can’t express how thankful I am because my Dewalt SDS drill started playing up a couple of days ago and had similar issues as mentioned in the video with it being dry, so I took it all apart, just in time as was showning slight signs of wear so added in grease and everything seems to work like a dream. Although when I first reassembled back together, hadn’t noticed that the little electrical clip had come loose, so when I screwed everything back together and tried it, it didn’t work at all. 🤦‍♂️so then had to take everything apart again, and suddenly noticed that the electrical clip had come apart. just one for the future for anybody else trying this.

Fixed mine by greasing the piston and hammer. Your video saved the SDS! Thanks!

Thanks for sharing this it’s worked a treat. Piston on my was bone dry and lightly scored but I fibre buffed the piston cleaned re greased and the drill is flying now.

I've got an older 20 Volt nicd version, it was a cast off and ideal for my usage, I'm inspired to give it a service now as its probably similar inside👍

[@miketucker7466]

Had one of mine apart yesterday and greased it - from my experience their very reliable

[@darcygabow1463]

Big thank you for that video.

[@jamiemorley9716]

Very helpful video just followed the instructions and done mine only problem is I seem to have done something to it as it only has rotary hammer on every function any ideas where I've gone wrong

[@mitafs]

Very helpful, I noticed you didn't use graphene grease, it's cheaper and DeWalt prefers it, probably because it means you have to replace the drills more often or fix them,

Hi Dean thanks for the video . I need to change the spindle on this drill as looks like the 2 locating pins have sheared off with only the ball bearing keeping sds bit in place . Is it difficult to do ?

[@vitormsantossilva8282]

Hi! Nice video, very helpful! Can you give reference code for the pieces we need to buy?
