Assembling an old Hilti TE72 rotary hammer

In this video you will see a Hilti TE72 get repaired and assembled.
I found this in a box near a garbage container. It was dirty and had a defective fan and conrod. For this video i will just focus on the assembly and therefor all parts are already clean and neatly laid out.
I am quite new to video editing and knowing what part of the video is more (or less) interesting. So please - leave a comment to help me get better.

This is the 5th tile project we've done where we've removed the old tile before installing new tile, and the first one with this tool kzbin.infoUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS . I want to cry for all the unnecessary work we've done in the past. With this tool, we removed tile surrounding a fireplace, as well as the hearth tile, set in loads of cement, in less than an hour. I highly recommend this tool. It was easy to use, and very satisfying watching the tile literally fall off the wall.

This Video is the best Assembling Hilti TE72 on KZbin! Thank you very much for making this. Will help me alot. I'am still stuck on removeing the Chuck on the front. Its super tight i have no idea how to remove it.

[@randomrepairandrestoration1766]

Yes its vert very tight. I put a screwdriver through the holes to get leverage. Another option is to put a metal piece through and put the front of the chuck in a vise, then turn the whole tool to unscrew it. The rubber gasket might get damaged and might have to be replaced. 👍😊

@@randomrepairandrestoration1766 i removed the rubber from the chuck and will try to heat it up to remove it with a big pipe wrench and a long cheater bar. Some allen keys broke before :D

В патрон нужно вставить пику-зубило и удерживая остнастку открутить гайку с помощью ключа в виде полмесяца в противном случае сломаете деталь под номером 34 и повредить корпус редуктора и тогда ремонт будет не целесообразным так как эта деталь уже не производится.

[@randomrepairandrestoration1766]

Some parts are easily available on eBay. Some of the parts are interchangeable with other Hilti tools. Even though a bit expensive, your local Hilti specialized hardware store should be able to order the parts for you.

[@SweUnpoor]

On the rotor tap that goes in to the gearbox there are a rubberbushing in my te72, You didnt add that to yours.. mine is brooken and cantt find any replacements, I whould have brooken alot of stuff if it wasent for U,.. :-) tnx!

[@stevecarr7338]

been a day trying to fix my TE72. I rebuilt it and get hammer action for only a couple seconds then it goes away. Then no hammer action just the motor spinning up. Rotation works, the con rod is great, replaced carbon brushes. Can't really think of what else it could be.

[@randomrepairandrestoration1766]

And this happens also when you try to "hammer" something? It will only hammer when its pressed/forced against something (like Concrete).

[@stevecarr7338]

So there's no hammer action even when pressing against concrete, there was a time that if holding the drill upside down would engage the hammer but then it would stop. It looks like I might be missing a washer / spacer @12:20 next to your thumb on the right. But connecting rod and piston are good.

[@stevecarr7338]

it's called a bushing, number 40 in the service manual. Basically the striker is getting stuck in the open position and isn't returning, so it's hammering for a split second then getting stuck. :Z@@randomrepairandrestoration1766

My husband has the same TE72 but it starts but won’t hammer what can the problem be please advice. Thank you

My bet would be the conrod. Open the oilfill and inspect the rod visually.

Thanks for a great video! What type of oil gets into the machine and how many ml?

[@randomrepairandrestoration1766]

Thank you 🙂 I used 75ml hydraulic oil. But i'm pretty sure you could use regular SAE20-40 without any problem. Maybe Even a bit more oil. 75ml 20HD (Turmopol) oil is recommended by Hilti

Bonjour, je suis tombé sur votre vidéo très utile pour le démontage de la Hilti te 72 j'ai un problème de percussion comme beaucoup de personnes comme dans une votre réponse je vais démonter le levier qui sert à passer de perceuse à percussion pour voir si la bielle ai cassé mais comment se fait t'il qu'elle tourne en perceuse coment se fait le mécanisme entre presseuse et percussion, merci de votre aide.

[@randomrepairandrestoration1766]

Hi. I'm a bit unsure of what you mean. If i understand correct you are asking how to switch between hammer and drill? If so, you just switch the handle with the black ball. If you cant turn it you need to open up and check what is blocking it.

[@Rocky-zt6qn]

@@randomrepairandrestoration1766 good evening, in fact I wanted to know why my Te 72 the drill function works and not the percussion with the burion if the connecting rod is broken it would not work in drill no. Thank you for your reply.

[@randomrepairandrestoration1766]

Drill function will normally work even if the rod is broken. Rotation is done without the conrod. In your case the conrod is most likely broken. You can get new one on ebay around 40euro. I recommend buying original Hilti part.

@@randomrepairandrestoration1766 Thank you for your help, happy new year

[@33bighands]

I have one that the bit won't come out of. It was in the drill mode and the guy using it lost control of it and it ended up flipping around and probably hit the concrete. Not sure because I didn't see the incident. The piece you push back to get it out wont release now. Any suggestions?

[@randomrepairandrestoration1766]

Maybe try giving the the drillbit a couple of wacks with a hammer invards or put the drillbit in a wise and a couple of firm pulls. It should loosen up the two metal pins that hold it in place. If it doesnt work then its quite simple to disassemble the parts near the front to loosen it up. Hope you'll fix it ! 👍😀

[@elrattyone6316]

@@randomrepairandrestoration1766 Oy! Mine is so tight I can't get it off at all. I've tried penetrating oil, beating the spanner wrench with a hammer... nothing. It's frustrating. I can see how it all goes together in this video (which is great) but I can't get the nose to unthread. I feel like somebody must've welded it on there! :(

[@elrattyone6316]

Got it! Had to put a wrecked SDS Max bit into the chuck and clamp it really tightly into a vice. Then I used a pipe wrench with a pipe on it. It didn't even get marred up... very much. Regular thread. :)

[@randomrepairandrestoration1766]

Beating it wont help. You need to use firm pressure. mine was also very tight and i put a screw through the two holes. put the head in a vise and turn the whole machine. Make sure it is in hammer mode. Hope you'll get it off 👍👍🤞
