Bosch Parts Service Online Illustrated Part List Control the power cable for wire breakage second remove the carbon brushes and control them on the collector surface for if there is a little black pin was coming out of it thats an auto protection build in then replace the brushes , but there are more things because there can be a problem with the electric field on a contact measure both coils and all the collectors (commutator around) on the armature that there is no-one lost the last option is the electronics

Maybe contact people from this factory to become some technical information about your question Possibly more likely than Bosch try it. succes https://www.alibaba.com/product-detail/1614011072-armature-suitable-for-BAK-GSH_60330652111.html

First to look for faultering contacts on electric field and carbon brushes sometimes a suppression capacitor can give some problems a worn commutator on the armature a switch can be overhauled with a direct cable contact to test to know if it is the switch test it out only with 2 persons for safety in that case.

seems as if the jackhammer motor is locked up and frozen might wanna be careful opening it up and freeing that motor up while its unplugged

Beware Time for service something does blocking the armature if that happens a bearing or other broken part.

Position 856 1617000836 a broken hammer piston in the worst case but you have to order 1 617 000 A15 a maintence kit and special lubrication used 50 ml 1 615 437 512 INSPECT CAREFULLY THE 1 617 000 838 Hammer Pipe for rips if all parts are unmounted of the hammer pipe tap it with a metal object then it should not have any dull sound treat like a tuning fork for control for rips. thats important before repair consideration before. The lubricant will be quite thick and that can also be the case only , (only have had its working hours on it) the revision of this hammers are easy to do it yourself clean solvent all metal parts that you re-use again to do the job you have a bench-vise and tools , for the striker pin in case there are no special tools neccesary like other hammers like a suggestion the Milwaukee 500S or other proffesional hammer because of the need of special seals and tools are neccesary , in between 1 and 2 hours are taken to service this Bosch hammers sometimes its neccesary to be aware of 1 ring to replace first of all because its easy to forget this ring on position 104 1610210095 o-ring that will very easy forgotten in practise with some grease replace it first of all spare parts.

me id use google earth to locate there service center (where it got sent to repair )and then see there (elevation) if it exceeds 3k feet (I suspect it might) then id gather this info and send it in a nice letter to your states attorney general for fraudulent claims , im betting one letter of intent to pursue consumer ***** from them to dewalt and you'll see a differnet outcome !!

This is going to be tricky. Kango was bought out by Milwaukee tools and that model is not available. The springs you are going to need to measure with a caliper for length, width and diameter of the wire. Compression specs becomes an issue. http://www.leespring.com/browse_catalog.asp?springType=C&partNum=LHL*&xsearch=Search The seal is the least of your worries because you can get sheet gasket material or use silicon gasket material in a tube. The brushes are another issue. https://www.repcoinc.com/brushes/

What is "comperes"? Also what does this have to do with HP Hammering?

• suggestion 11241-EVS is not a breaker hammer but a rotary hammer but has almost the same good quality as a breaker hammer because its a reasonable solid product with a liquid lubrication.

Solvent clean the front drill and chisel holder in the spindle thoroughly to control before buying a maintenance parts kit , decision to take the step ONLY IF............ the spindle (most expensive part) is smooth has no rips or is worn but first inpriority check in advance whether the three SDS driving lanes for the bit internal closure and drill -drive of the drive spindle =pos 25 in the drawing is still be adequate enough a 1.5 mm and round tops is critical. and below that its not worth to repair. because the working hours on it have been achieved. Otherwise If its looked like the 3 lanes inside the spindle all three are always the same size about 2.5 mm thick and are square topped the spindle (and the other parts are must have to be in good condition to service. buy the maintenance kit its in the drawing to find in the parts list pos 897 and oil partslist pos (898 or 895) for if you have more then one rotary hammer to service. Most cause its conclusive for only this parts but a priority is to replace ALL pieces of the service parts. even the carbon brushes look that after replace the green ring on pos 856 that this hammer piston connecting rod is correct mounted on the right side again with the 4 little stips on the (bearing) outside thats coming downsite on the eccentric cog wheel for a smooth working for the plastic plain bearing on the metal connecting rod, At the slightest mistake in the parts and lubrication breaks this connecting rod soon. The striker pin has great priority to clean and control that part against leaking a retainer ring should be removed by use 1 or 2 little screw driver(s) in the small holes on the side of the spindle can be seen this ring. if the ring comes loose tilt the ring cross with a long screwdriver pull it out with a nose pliers. to get the (striker pin or impact bold (the part thats beat the chisel )by other brands named the special ring has exterior little orings inside becarefull and look first inspected how its build before there will one come out to push it again inside if one will come out. There is also a new retainer ring for the parts around the striker pin in the delivered maintenace kit By replace the several parts beware on one ring not to forget a very important ring pos 104 to replace it and mount it with some sillicon grease in the right groove before in order to prevent a disappointment of leaking oil because if leaking oil /air after a while the parts will dried out in a very short time and will burned out soon. There is one problem rised between me and this kind of BOSCH powertools about the ring(s) in pos 102 there are 2 shim (bearing) rings pos 102 to find by the service handling and what you will know from me is that you must look that there are two shims to find instead of one because of to get a correct backlash measure between 0.08 and 0.22 that's the right tolerance to adjust the shim bearing rings to have some tools ONLY to know how to handle if they are forget the second shim ring in your model if you are going to make service if you only have one shim ring because there where failures in the drawing by Bosch on this and to find more about the use in some other comparable bosch models like gbh4-32dfr or 4-40de that will have in order to adapt the backlash adjusting have a failure if only one ring is used. More on fixya to find about the pos 102 position rings by Bosch in several models. Hoping that YOU HAVE 2 rings of pos 102 you have nothing to do to concern on let it be as it is. only if one ring you should hear the difference in rotary position , it should not be turn smooth. But if one shim ring is used only like in the drawing it must be a factory drawing failure. look on the partslist by the model you have it shows there are 2 different rings to buy or order of the same pos 102 for it they sell you can buy if you do not believe on my story its so imortant to adjust the gears for the backlash if only one ring is in this machine you will have to order 4 new pieces 2 of the 2 neccesary to adjust know to make the backlash rather on 0,08 mm then 0,22 mm as soon you have adjust because otherwise the machine will make the rotary gear worn in a to short time. If its has only one shim ring and its have making already a very bad noise in the rotary drive position replace only if its worth all to gether to service also pos 51 and pos 860 Bosch 11241EVS 0611241739 Rotary Hammer Parts

take a sample to an appliance repair center or to an electric tool repair shop many brushes are generic as manufacturers seldom make their own and brushes can be shaped to suit

No parts here and no connections other than a Google search which I assume you have already done.

Try motor rebuilding/repair shops or ebay for brushes.

if the internal motor still runs , but the chisel doesn't move , this is a sure sign that the drive pin has broken off , un plug and remove lower part of tool , there just after the motor shaft is a flat gear looking item , it has a pin sticking out of it bottom side , except I bet yours doesn't have it sticking out any longer , this pin will need replaced , this occurs when operator gets tool stuck in hole and pulls back while running it , ive changed a few in years past

Need more information. What type of equipment is this on? What is the make and model? How old is the equipment? I might be able to help if you can supply this information.
