Repairing a Milwaukee K500 ST Hammer that has lost its hammer and is no longer hitting hard.

- These milwaukee hammers wouldn't be the best machines on the market. They are prone to the hammer pipe or striker inside failing and destroying the machine.
They are also I find, very low on grease when new. They simply do not install enough grease during manufacturing for the amount of empty space inside the gear box.
If your looking to buy a hammer, i would recommend a Bosch hammer GSH 11 E over these Milwaukee's any day.

My favourite kind of video on CZcams. While my lazy ass is in bed I'm learning how tools are being made, how tools are being broken and how a legend makes them suffer for a bit longer. I genuinely wanna thank you for sharing all this precious content!
Here’s why hilti’s are one of the best. Very few of their tools run on grease. Only a select few of the smaller hammer drills. Most of their line up of hammer drills run on oil. And some have different chambers that separate the gearing from the piston and striker. That chamber is usually oil filled so they are certain the o rings around the hammer mechanism never run dry. That’s quality there
Same design setup as a makita hammer.
But in the end you pay 3x for a machine just as well made as a Bosch or Makita but very hard to repair or service on your own.
Which brand of grease to use for that drill
does anyone else find this video seductively relaxing?
Yup
No. You pervert.
Love these videos, deserves many viewers 👏
So seductive
Can't believe you only have 63k subscribers, there so many things learn from your videos. Thank you for sharing your knowledge
Keep up the good work. Hope you hit 1M subs soon
Hammers need to come with an hour counter honestly. A tiny OLED display somewhere to display the runtime hours. Would help massively with service intervals and counting the runtime hours in general.
Klauke has a tiny OLED information display on their machines and they are a small specialized manufacturer so Bosch, Makita, Milwaukee etc can do it too then.
I must say you are one of the best tool repair channels I've seen the best to be honest and we can all learn I ting or too from you and I've only found your channel a couple of days ago which is amazing because I have searched a number of times for repairs like this and your channel never popped up but tell me what is the name of that grease you use and I presume it's good enough to use in all machines out from Hilti power tools I suppose
The thick grease is bosch 001. And the lighter white grease is hilti hammer grease
@@deandohertygreaser is there a Grease that you would recommend that can be bought in the general stores that would be something like Hilti hammer Grease I just find it very hard to get parts from Hilti
@@repairs524 NGLI 000 or NGLI 00 viscosity grade gearbox grease. The goopy white Hilti grease looks like NGLI 000.
Hi sir, where i can find the orings? Any link Best regards.
Could you tell me what type of grease you use please ? Have an old Boschmann breaker that hasn't been used in years and hammers sticking quick tap of chisel on floor and goes again hammers really well when going but must be due a service .Regards Bryan
I have to do this in a couple days when my new piston rod comes in what type of grease are you using
So get brushed tools so when they go bad u can just put new bearings and brushes in them, then to buy brushless, also got the Milwaukee M18 surge impact is there anyway to upgrade it to get more torque from it it really lacks on torque it puts screws in great but it could really use more power
Milwaukee looks easyer to service then the Bosch could just be me
Great video
Mine overheats , any suggestions. Well, i just let it cool down and start using it.
Anyone have an idea what keeps the selector knob in place i can not keep mine on anymore
Dear @Dean Doherty I received a remarkably similar Wurth BMH-40-XE hammer with some other used tools. It looked good in the box so I thought it might work. Tried it out and no hammer action. Your video was the only one that I have found got into the nitty-gritty of actually fixing one of these. It was my first time ever touching a hammer so I had to open it up to looky-loo and troubleshoot. A bunch of oil came out that was unexpected for me. Poked around and nothing seemed wrong. Ran it slow with the cover off and no hammering motion, I noticed if I pushed the chuck with the cylinder sleeve in all the way back the piston would sometimes try and push it out like it was trying to work.
I have not needed a hammer before but have a few personal jobs in the future that might benefit. Is it worth buying a seal kit (US$35-42 with a piston the kit is almost US$100) and oil to try and fix the hammer or do I sell it as broken and just rent a hammer when I need it?
The BMH-40-XE wurth is actualy a bosch hammer. wurth dont make many tools so rebrand a bosch gbh 5 as their own.
is the piston moving at all ?
the piston is driven by the eccentric gear at the back. this gear is driven directly from the armature. make sure the gear on top of the armature that drivers everything is not stripped of sheered of. (small one in the center)
after that, it is probably a selector issue. make sure the selector in the top cover is locating into rim of the selector gear below it.
CAN YOU REQUEST THE BRAND OF THE GREASE OIL YOU USE?
شكرا
Can you help me ? This Thing on 5:25 . I cant Push it all the way in and cant put the C Ring on. Am i just weak or did i something wrong ?
Where are you based ?
Hello. You have a part number for o ringe set? Thank you very much.
Hi Dean, which kango would you recommend? I normally use a bosch gsh 5 ce, anything similar you'd recommend or stick with the bosch?
For that size of hammer, mist go with the bosch. But the metabo is of similar quality and built style, plus it is a bit cheaper than the bosch. U see more and more hire companies using metabo hammers.
Other option would be the makita, they are more complicated and expensively made. And also more expensive to buy.
Where can I get those green wheels ?
Hey were do you get your parts ?
Recomendation on grease? I'm about to fill mine with bearing grease....
DONT do that.
You need a low viscosity gearbox grease. NGLI 00 or NGLI 000 viscosity grade.
@@alouisschafer7212 Oops, thank you for answering!
@@bumblingfool For sealed! gearboxes that are expected to run for extended periods of time and heat up aswell you want the most liquid grease available. It will flow around and keep everything coated in lubricant.
The goopy white grease you see Dean puttin into this hammer is NGLI 000 viscosity.
BUT when you have a gearbox that is NOT sealed well you cant use such grease because it will leak out.
Some Bosch hammers have gone a step further and use straight oil in the gearbox.
Do you ever consider the moral hazard of keeping Milwaukee’s alive and thereby encouraging boys to keep buying them?
Instead of “this’ll be easy - just 2 o-rings, an hour or less of Dean’s time and some grease”; it must be tempting to tell the customer “dumpster is out back. Come in after you’ve binned the red rubbish and I’ll sell you a Bosch”
Thats unethical to do for a repair shop.
Repair everything that comes in but make recommendations based on experience is what is right to do.
Washer my friend 😅
Milwaukee hammer drills suck balls don't @ me
I used my Milwaukee SDS Plus Rotary Hammer Drill Twice. And it stopped working. Twice. I have $5,300 invested into this company and I’m considering switching to a more reliable company. Milwaukee has just been feeling like a junky clunky tool company as of lately.
They are, that's why I warn people to stay clear
@@deandohertygreaserWhat do you think about dewalts new line sds max rotary hammer drills brushed corded ones ?
In the EU
At our company we use every company
So mill Bosch mak Würth DeWalt
The all stop when they are being used and abused
