SOURCE: bosch brute 11304 runs but does not hammer at bit

Sounds like you have a broken connecting rod. The easiest way to check for this is to remove the 4 cap head bolts holding the cylinder on and remove it. If the hammer piston comes off with the clinder you should be able to see the break. If that is ok you may have some stripped gears or a broken spindle somewhere. But I really think it is the connecting rod.

SOURCE: How do I drain the gear oil from a Bosch Brute

Brute hammer uses special grease sold as service kit. This kit contains enough grease to lube hammer and replacement bolts that hold springs along the bottom. Check www.toolpartsdirect.com for parts and kit. Remove the lower half (tube) of hammer, also remove three bolts that hold springs and remove assembly from tube. Wash out old grease. Grease will be oil-like only when hammer is very hot, otherwise grease is paste-like. Good luck.

SOURCE: I have the Neiko electric

I have seen many different brand names on this tool depending or retail outlet / where purchased, including Sears, however none of the sellers offer replacement parts or are much help when a problem arises. This tool is a Chinese copy of the Hitachi h65 and parts list for Hitachi hammer can be seen at www.toolpartsdirect.com and many other web sites found by google search ( hitachi h65, or hitachi h65 manual ). Instead of taking apart the lower end of the hammer (if hammer still functions ), just remove the oil fill compartment cover and the oil felt retainer ( or only the felt) and introduce light oil directly into hammer to flush out old oil / debris. After you are satisfied with lubrication of the hammer, clean felt with diesel fuel and re-install. The felt is a wick and transfers the oil to crank. Place the wick in proper place for crank to catch oil (or replace wick with hitachi part). If oil does not transfer, use lighter weight non detergent oil. If you still want to take hammer apart, (remember that no parts are available) you will need to take the rod off the crank by removing the side cover to easily pull the lower end. Good luck with your repair.

How to disassemble a Bosch 11241 hammer drill.


This is a pretty complex tool to tear down, make sure you're up for it.
1) you need to remove the bit holder assembly (#21-30) by prying the rubber seal off on the end, sliding the sleeve off, removing the hog ring, and then the 2 pawls along with the remainder of the bit holder parts.
2) In the nose of the tool behind the bit holder is a large snap ring (#154) that must be removed.
3) Remove the screws on the gearcase cover on the top (#873) and remove the cover.
4) The entire barrel assembly will slide out of the nose (This is generally not easy)
5) Using an o-ring pick or small screwdriver through the holes on the side of the barrel you can reach another hog ring on the inside - once released you can push the striker and hammer out from the nose out toward the piston end.

I would install a service kit and fresh oil if you decide to open this up Bosch 11241EVS 0611241739 Rotary Hammer Parts

Bosch 11241EVS won't hammer


Not all bits for hammer drills are the same as the slots in the sides of the shanks are different between makes . There is a standard between hilti and ramset drill bits but other makers have different ideas Check out the shanks of your drill bits and look for the slot that holds in the bit.

On my BOSCH CSB 470-RLE 470w electric drill the chuck is slipping i can hold it in my hand and it wont move


It is a spring loaded hammer drill. You need to push the chuck down just a bit for it to engage the clutch. If it is still slipping then either the clutch pieces (items 23 and 32) are worn or item 32 is spinning freely on the spindle shaft. Here is a parts diagram.

No hammer function


if the tool still runs and you have inserted the proper bit, what I would try first is jamming the bit into the concrete to see if the striker is stuck and if still no hammer it would need to be taken apart and rebuilt with all new o rings and seals. if you try this yourself make sure you buy the small bottle of oil and some lube the the seals.

Bosch 11222EVSG hammer drill not turning


Couple things to look at, First is the selector in the hammer/rotation mode? Without a bit in it does the collar turn when in the rotation mode. Are you using the right bits for this tool. If yes to all of these I would look down the spindle and make sure that the pawl are in place (they lock to the bit for rotation) Let me know and we will dig deeper.
