CONCRETE HAMMER DRILL RESTORATION | Hilti TE12S 

Thank you very much. I have this same Hilti and it needs an overhaul. I have used Hiltis over 50 yrs and have always wondered why it is so effective and now I know it. The piston system is real mechanical marvel. But why didn't you use oil at all when putting it back. You should always use tiny amount of oil to prevent wearing.

I have this drill from 1977. It's a great machine and works perfectly

I love Hiliti. The best tool!

Some times with "plastic" cased tools like this, you can use a heat gun to heat up the plastic to bring back the color and remove any brushed/scoffed areas. Don't know if that type case would work with that option, but could try and see. Thumbs Up!

Болшой спасибо

Nice videos man ,you are great !

Why would you put the finished product at the beginning of the video? Leave us wondering, man!

대단하다 와우~👍🇰🇷👄

You have done a great overhaul👍👩‍🔧

Давай, железной щеткой ещё по обмоткам задень, вообще хорошо будет.

Not replaced the o'rings, bearings? Greetings from Brazil.

It kind of hurts to see you reassembling this nice machine without any grease on the metal parts, without new bearings and o-rings and without heating the housing of the bearings to get them in without force or with the corroded cable shoes of the old brushes…. the look of the machine after restoration is very good but it's probybly unusable like this or would work only a short time... it could be a perfect restoration but in this way it only Looks good :(

you have any videos of a te17 front seal being changed ?

You should send some of these refurbished tools to BOLTR AVE for testing and review, he’s a fellow RU-vidr

Nice to see you finally restore a high quality electric tool rather than the usual crap

Can anyone tell it's manufacturing date.

You have that tool on sell ?

да ка раньше кондово делали инструмент , надежно , а щас наоборот думают как послабить конструкцию что би запланировано через определений срок вышло из строя

This time you didn't clean it well And didn't grease it also

я б назад не зібравби.

Looks too new

Don't reveal the finished product at the beginning of the video.

Great work my friend! Hilti makes some great tools, and you brought this one back to life!! I just restored an old electric hammer from the 1930's, but also showed and demonstrated newer ones... Do you mind if I include a link to your video in my restoration video description? Hopefully it'll bring more views to your video, and people can see a newer concrete hammer being restored!

What kind of finish did you „spray“ on the red housing, after sanding it?

The first drill Hilti restoration i see on RU-vid. It's great!

Great job! I saw oil being poured-well done, but where is the grease on parts that are subject to friction?

Я понял зачем он снимает видео - чтобы не забыть как собирать это всё обратно :))))

Yo tengo que restaurar un T17

Did anyone else need the loo a few minutes in due to the rain lol 😂 great result mate really enjoyed it great restoration

What oil did you use? Love your videos but I wish you would provide more details like that.

that little piston is so cute, looks like a mechanic's keychain

Exelente.

Thank you for sharing your experience. Like.

Hello, I am restoring a Bosch drill, but I can't find this part that you also have on your HILTI, (the filter) 44 - SUPPRESSION FILTER BSD-1617328002.A71 1617328002, I don't know what this part is for...

Hi Specialist Excuse me but this was neither a repair nor a restauration. You "don't need" any spareparts - you are like a miracle healer 🙂 I saw some defect parts you at least reassambled: 1. The small Rotor bearing, 2. the three brake lever, (these have to be changed allways) 3. the brake bushing (this has to be changed in every repair) You will not have pleasure with your TE12S Hilti after this unsuccessful repair. The Rotor bearing will crack an the Rotor housing wil be demaged. It's not necessary to paint the housing parts - it's not relevant for the performance of this tool. It's like to polish apples 🙂 It looks nice but the technical conditon is important. Good luck 🙂

I was just holding my HILTI TE12S with One hand and with the other hand a screw driver, watching this video ready to follow step by step the restoration, by the 5th minute i decide not to f**k with It and just Buy new one....... 😜🤣🤣🤣 Daaaamn to many parts 😑😜

The Ingersoll Rand 114GQC Air Hammer ru-vid.comUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS was just the tool I needed. I Use it to remove stuck bolts. If held at the right angle you can cut slightly into the bolt. Then turn the air hammer to where it will hammer the stuck bolt to unspin the bolt. Given a little practice it works great. This air hammer gives you the control needed to get the job done right. Very powerful yet still does not seem to have as much vibration as other guns I have used. One of the best I have gotten my hands on.

I have the same Hilti TE12S but it's not working anymore due to damaged trigger switch. Is there anybody who can help me on where to find this switch?

Many thanks, I have The same one and I didn't know It need oil. I will watch this video some times more to see if I can restore mine, well I'll try at least oil it.

Nice work

Auseinander nehmen sauberer macht und dan die alten Lager, Ohrring, Simmerringe verwenden, dass ist für mei Dafürhalten keine Restauration, sondern "Pfusch" .

What type of liquid and sand paper you have used for sanding plastic red color cover? and what you sprayed on it for shining?

YOU ASSEMBLED THE BALL BEARING ASSEMBLY WRONG WAY. The balls must be put outwards against the metal bushing.

those used bearings looks like new :)

In Hungary HILTI stands for concrete drill.

I really appreciate that you don't paint the tools a tacky color with spray paint and that you keep the original color. Good restoration.

It's pretty amazing that you remembered where every part fits,you sir have my admiration

great stufff but only pakistans completly take care of stators starters id like to see thoze rebuilt

SUPER.SUPER.. VERY VERY..THANKS...

Wish you wouldn't show the "After" till the end of the vid.

How long did this take? Just curious, and don't say 20:16.

Now that's super, another drill restored .

Question 1: Is That The Makita Impact Driver That You’ve Restored? Question 2: Does Cambodia (The Country You Live In) Supply 100 Volts Or 230/240 Volts AC?

Beautiful restoration, beautiful work.

👍😎🍜🔧🔨

I always waiting your new video

Good restoration 👍 I like it

Our hammer drill at work looks like that after the first 3 uses lol

Hey this was an easy disassably, washinga und assembling the tool. You used no new sparaparts. Minimum, all the o-rings and the brake (3pcs) have to be replaced. The clutch has to be messured and replaced otherwise you will get a capital defect in the gear afterwards ( in the next 14 days at the construction site) You won't be able to drill tiles in the bathroom because you will always have the beat from the percussion piston. I repaired this tool in germany about 7 years at the HILTI repaircenter in Bebra. We would be fired if we would repair this tool in this way you did. :-)

No have spare parts for these models , be careful with some tiny details 👍

I didn't like so much the intro music and after-restoration images. I prefer only pre-restoration photos of the tools and no music as the previous videos. In any case your restorations are more than excellent and professional in your channel which I undoughtly wait with impatience to watch!

I'm impressed with the restoration, but more so that you remembered how to put it all back together! Great video.

nice cleaning

A bit strange, waxed and polished plastic cover, but uses the same old connection cable. On such a machine it is the one who has the greatest risk of being injured. And that can be dangerous too.

Please do not show the finished product at the start of the video, is like knowing the end of a movie at the begining. Thanks. Love your work!

Po tym pierdolnięciu gumowej dławicy 18:00 poznalem, że jest Pan z Polski.

Tu es le meilleur !!!

Fantastic, thank you 👌👍👏👏👏👏😍

Wtf no grease on the stuff that dont get oil? Like bearings

Забил смазать шестерни салидолом, а так пойдёт.

Nice hammer drill old Hilti 1990?

can anyone tell me how to remove the drill bit in the keyless chuck i got the same model came from ny grandfather thanks

Does that oil grease the gears. Such a compicated drill. Seams a drill like this could be simplified with less parts. Like what engineer thought of this. This needs a spring here and shaft here a sleeve here a pin here an O ring here. Another pin a ball bearing. So many parts for drill.

you didnt use any lubricant when putting it together? which gear oil did you use?

На него пожизненная гарантия, зачем ремонтировать ? Скоро будут реставрировать инструмент которому 3 месяца со дня производства

Подшипники менять надо, он их обратно устанавливает.

Nice job, also flashbacks to my apprenticeship seeing one of these old TE's.

Faltou lubrificar

What do you use to remove the old grease from the tools? What cleaning solution you use?

How do you know how to disassemble these machines? Do you go by some plans or something?

good

Always a pleasure to see your video, I get to learn something and I like your neatness in your work, please keep posting more.

🤔🤔

Great job! Thank you for not having ear bleeding background music.

GREASE!!!!!!

I have the same drill and it's missing one part that he is putting in last at 19:22. Is it just a dust cap or does it have bigger purpose? Is the drill still usable without the part?

some of the parts looks almost automotivegrade. That drill will run for another 30 years.

Xin chào! Bạn ở VN phải không?

putting the finished result in the beginning made me not watch the rest of the video, just letting you know, ive seen you and others do this before and its big mistake.

Can anyone tell me when the TE24 was made ?

Great resto ! Just never forget these tools need lots of oil and grease ! 35cc of oil in the gear box and lots of high temp gear grease on the other moving parts. The right type of oil and grease is crucial since these types of drills are under a great deal of stress and can get very hot. I have used Hiltis for years. I know them well.

Che vernice hai usato che non ha rovinato il martello?

Don't want lubricating grease or lubricant?

Hilti gear is the best, use it all day long 😎

you do not go up the device with grease at the gear and piston?
