If you mean the front striker pin you will need to remove the circlip up inside the spindle. You can see it through the two little holes just above the spring.

I need to put a service kit in my 11241evs but don't see an obvious way to get it apart ,I have the schematic to re-assemble it. Can u assist ?


first remove parts of the chuck then dismount the grey housingcover 873 on the top 6 screws

dismount the powercable cable can sometimes be handy if removed the chuck and parts there is a great locking ring part 154 this must be unmount and removed and after that place the machine in a great bench vice if the old oil is removed and beat the hammerpipe out of the machine and make everything clean with a solvent cleaner and replace all parts and rings exactly at the site as they are present, but the front of the hammer tube there is an impact bolt locked its usefull part 854 there is a locking ring thirt ring in front that must be removed with a little screw driver and then 841 striker pin called but I call it the impact bolt must come out the hammer tube the other striker battlepiece i call it comes first out if you have replaced all parts with new the last is to replace the carbon brushes. important is the order of the rings what will be parts 47, 102, 48, 51 for this drawing its correct placed it was cost me 5 months to ask 4 times to change the order of a fault in the drawing of the gbh4-32dfr model beware the parts order for this machine drawing is correct ! by bosch and nobody believes me until now the parts are on the most drawings still today wrong on great online sites because rings 102 stands in front of part 47 but without making any publicity Bosch has changed the drawing of that machine but anybody else on internet have the old manual drawing of the gbh4-32dfr rotary hammer thats fast the same as this rotary hammer and i have tried 4 times by some bosch students there to make clear that there was an erroneous drawing is but they believe only Bosch but they have do not look at Bosch now, it was the first faulty drawing ever made by bosch i have seen, but no thanks to me and the service of bosch has allways a difficult German mentality wrangling for warranty but the tools are oft great.

Bosch demolition hammer wont hammer


MUCH NEWER BOSCH demolitionhammers have a special consumables kit you MUST use anyway its marketing technical made exactly on the calculated operating hours.

Every tools has his own kit and by the heavier models of powertools a very special lubricating oil instead of grease that was used by the older tools that are working with a slower tapping block instead of a very fast battle piece.

My bht150 bostitch is jammed


First slide off the rubber grip This will expose a pin that you will need to remove. Remove the two bolts on top of the hammer with a 10mm wrench. These bolts hold the striker plate guide. Place the hammer in a vice to lightly compress the hammer head. Remove the allen head bolt located on the end of the head. This bolt holds the striker slid that strikes the staple. Remove the pin that you see that was under the rubber grip. Just tap with a punch and then you should be able to remove it with a small set of pliers. Now slid the enter assembly back just enough so that the jammed striker slid will come in contact with the striker guide face. Turn the hammer over and strike the top of the hammer on a piece of wood. This should free the slide and jammed staple. The staple and slide will come out. Take a file and deburr the slid and add a dab of grease to it. To reassemble, Attach the slide guide first, but leave it loose. The rest is reverse order. Hope this helps.

Bosch 11224VSR drills and hammers but not both. Makes loud stripping noise.


If both functions, hammering & drilling, work correctly on their own but not together your selector knob may be the issue. On the back of the knob is a driver pin that moves the necessary parts to make your tool drill, hammer, or both. If it isn't moving those parts to the exact right place, one or more of the functions may not work. Try moving the selector halfway between positions and see if the gun hammer-drills. If it does you have problems with the selector or drive pin. If it still does not you may have internal parts problems that can only be diagnosed by working on the tool with the knowledge of how it works and how everything inside should be.

Most of the time the o-ring on the striker needs changed. Look closely at the hammer piston as well, once in a while (very rare) the piston will develop a crack that allows air to escape by the striker, keeping it from striking the impact bolt. Make sure to add a little extra grease when going back together as well.

Operation Problem with breaker


I worked at a tool rental /hire while going to college and repaired many of these breakers. For this tool to work most efficiently, we would store them in their stand upright in a heated area (during winter). This tool requires special grease sold as a service kit which includes orings and bolts for retainer area. Remove large piston attached to connecting rod and remove inner striker (fits inside main piston) this striker is the source of problems. Clean inner cylinder and striker and lube with bosch grease, not too much. If you lay the hammer down or store with bit side up this striker will migrate to uppermost part of the main piston and be vacuum locked thus not hammer. Also remove and lube the impact bolt and look for damage. If chipped or cracked this part must be replaced. Parts/list are available at www.toolpartsdirect.com. enjoy

What age is the machine? If it is fairly new it might just need to be run a while for the grease to loosen up. If it is older you will need to make sure it has enough grease. These tools don't need a great deal of grease, but too little will soon be thrown about and disperse too much. Another problem with these is if the inner cylinder, that moves up and down to create the pressure for teh striker, has a hairline crack, it can be quite hard to see when the part is dirty. When running though air will leak out and you will loose hammer action but still have plenty of vibratiion. Another thing to check is to take the piston/cylinder and striker out and hold it facing down. The striker should slide out slow and steady. If it falls out too fast then the cylinder and/or striker is worn. You may be able to rectify this by applying a bit more grease. If it doeesn't fall out at all then there is a build of grease behind the striker causing a vacum holding it all together. You can solve this by pushing the striker in a little way, and leaving it standing for an hour or so with cleaning solvent on top. It should work it's way in and help release it. It may still need to be 'persuaded' out a bit aswell.
