Repairing a Bosch GBH 8-45 D hammer under warrenty. New motor, gear and service.

The most impressive thing about these videos is how every little bit and screw is just casually thrown in a pile, and yet you still manage to put everything back together

This Bosch demo hammer had so many pieces! Its amazing to watch you assemble all those lil pieces so easily. Maybe you've got a blown-up diagram to look at(off camera, of course😉).

I am surprised that they Bosch didn't just give you a new one, the price of the bits, plus your labour, incomparison to the cost of a new one

[@deandohertygreaser]

But if they simply handed out a new one. They would never know this part failed. Repairing under warrenty is a feedback loop, so they can always improve thier tools and keep them from failing

[@brianwheway1933]

the old unit could be sent back to the manufacture for closer and lab inspection, this would keep an eye on possible weak spots in manufacturing and component failures, I would have thought a mass produced item would be cheaper to send out a new unit rather than paying a repair shop to repair it, @@deandohertygreaser

[@davidsmith-ih2kk]

Just out of curiosity, what difference does it mean being under warranty . Like who then actually pays you, the customer or bosch, just wondering about the actual logistics of payment. An excellent tear down and repair video as usual.

[@dankoston2904]

The company who made the tool pays for the warranty

[@BlazeAmrabat]

The brand sends the parts, the service owner/together with the brand pays u the labor. Some brands require pictures but usually u just put the serial number of the machine under warrany + picture of the invoice or the receipt.

[@davidsmith-ih2kk]

@BlazeAmrabat thank you for the explanation it was very concise

[@gedeminasnacys7257]

depends from what country you are. i work in shop in lithuania(europe). if it is waranty case( waranty filed in their page( bosch) - they give 3 years waranty. if devise broke and its under waranty time - we filled special page- dpd courrier comes and pick it- send to their repire shop. parts and labor goes from them( if its waranty case), or custumer should pay if its not( like water damage)

[@nathanhazlehurst484]

[@ZenonCid]

Thanks for your video, it's helping me a lot I have only one question: What are the specifications of the grease you are using? I'm looking for grease. But I am not sure if the same, that lubricate the bits, can also be used on the gears. Thank again.

[@deandohertygreaser]

I am using bosch hammer grease, 1615 430 015. the chisel and hammer grease is completely different. you cannot use chisel grease that lubs the tool holder and chisels, inside the hammer.

[@jasonbuckler190]

Great work. Silly question, but why does it seem some Bosch replacement parts (like fan cover) always come in Makita blue?

[@rafaelbenavides282]

Buen trabajo, se nota que sabe lo que hace, pero muy feo que al desarmar tire las partes, considerar tener más delicadeza para futuros videos

You sure know the score on tool repairs, I have the model before this I don’t think I could take it apart and rebuild it as fluently as you can. I am doing a bit more though

[@gutsngorrrr]

[@SteveAndAlexBuild]

Photographic memory , very impressive 👏🏽👏🏽🧱👍🏼

[@tamask001]

The other Bosch blue tools you repaired didn't look all that different than the home gamer green ones, but this is very obviously on another level. It's built like something you would use to break a tank. Question: the original gearbox grease looked black (moly?), and the replacement white. Does the exact grease type matter?

[@tdotw77]

I think it just gets 'dirty' from the metal(aluminum) wearing & discoloring the white grease. Although this isn't my field of expertise....I'm the end user of these tools. 😅👍👌🔌⚡⚠️🛠️🔧🔩🗜️📏📐✏️💪

[@tdotw77]

And yes this is a high end professional model, not something a homeowner would typically need. Unless they're demoing brick, blocks, concrete or removing tiles(very handy for that w\ scraper blade)👍👌

[@IDuBStepSZ]

@@tdotw77 From watching AVE, it looks like most companies actually do use moly grease.

[@IDuBStepSZ]

Moly grease is better, but as long as a good quality grease is used, it's unlikely to make that much of a difference. Long term, if it doesnt get regreased again then there will likely get more worn down. They do generally use very hard steel for the gears though, so it's going to take years to see significant wear.

[@gplusgplus2286]

Yes the grease gets black as its being worked, same with the engine oil in your car.

[@danieldoherty8009]

What type of grease was used ? Two people asked already ,probably water based ,lithium.

[@apakansaja8505]

*I'd sent the same to a shop for repair. The people there said the same can no longer be repaired. Asked why, they said the people that know how to repair it have all died. Bad luck. Suggested to me to just buy a new ones.*

[@MikeDiCiero]

How many leftover parts do you thing he’ll have after assembly? :-)

[@nemanjatasic4657]

What could be a reason for low hammering power on the same model? Could be that O-ring sealers on piston? Motor seems to be fine, also error(red) light doesn't shine.

[@deandohertygreaser]

Needs a service.

[@bradley4369]

hey bro good job，but you forgot No.158

[@larasmileshmish144]

What is the name of the grease and is it available on amazone ??

[@pierredewez7358]

Which kind if grease are you using. Normaly Bosch ask to use two different kind of grease in this hammer ? Is that important ?

[@aetorres7422]

So it's basically a new tool why wouldn't Bosch just replace the whole thing if it is warranted?

[@paulthompson5416]

The spares cost Bosch pennies to replace

[@jcoul1sc]

Won't give work for Dean, and far cheaper to replace especially if designed like bosch

[@deandohertygreaser]

Good question, simply answer feedback. This is actually a good way to tell how good a brand is. It's actuly not a good thing to simply replace every broken tool. That's now cheap disposable tools are some cheap and useless. Big brands want thier tools to work right so they use the spare parts being sold to see what parts are failing most often and identify any repeat failures. So if this where a common problem, bosch will redesign and improve the part. You see this quite often. And you can see what parts have been redesigned as they normaly get a new part number. This is what keep the quality high. When a manufacture simply replaces a tool with out fixing or looking at it, it means they have designed and built them as cheap as possible to make the disposable. And have no interest in if they fail. Also this shows how cheap disposable tools actually are, as they have already allowed for the extra cost or replacing tools in the price if the unit to begin with.

[@Mark-tj5xo]

Amazing work. It’s shocking just how many ppl don’t care about sending a perfectly good tool to landfill.
