You can use an adjustable face spanner wrench to remove that cap. I don't remember the pin size but you can measure the holes and get the appropriate size. You can remove the whole plate with the armature by undoing the 4 cap screws. Prior to removing the motor plate you have to remove the handle plate from the axle that goes through the body. Undo the nut that holds the assembly on and slide it off. You can now remove the Armature plate. After removing the cap screws pull the assembly out about 1-2 inches. You will see the wires that go to the field attached to the brush holders. Remove the screw that holds these wires to the brush holders. You can then safely remove the whole assembly. This also makes it easier to remove that cap plug with the spanner wrench, because you can now put the whole assembly in a vise. I always heat around the cap with a torch before doing anything. Then I tap on the plug with a hammer a couple of times and voila it turns alot easier. Corrosion almost always builds up on this cap because of the different metals. (Steel and Aluminum respectfully)

Your hammer may have a broken connecting rod. To inspect this make sure you ping the cylider and body with marks so you line them up the same way. Then remove the 4 cap bolts that hold the cylinder to the body. Remove the cylinder and inspect the hammer cylinder and rod. If the connecting rod is not broken you will have to inspect the gears and pinions to make sure they are ok.

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.

I would say that the motor shaft is probably bent and will need replaced.there are bosch service centers all over unfortunatly the price of parts especieally if it is a older unit can be almost what the unit costs.Sorry I'm not more help as I have several bosch tools in my shop and they are top quality tools. However I also have an old 65# electric breaker out there that is gathering dust because it has a cracked armature and the parts alone to fix it are in excess of $800.00. Best of luck to you and thanks.

I am an electrician, 230V means it is single phase. It would be 415V if it was 3 phase. It will have a 3 pin plug, if the centre pin is bigger than the top two it will require a 15amp powerpoint to power it. 3000W / 230V means it may draw 13 amps even though it has 9A on the tag. I would expect it to require a 15amp powerpoint.
