And the second reason: disruption or failure of striker pos.28, resulting in a curvature part and the shock pulse transmission impossibility.īreakage are eliminated complete replacement of defective parts. There are cases, When snack drummer in the cylinder at 26, which leads to the destruction of the cylinder and the inability to create an air pressure in the hammer barrel. Friction bearing collapsed cylinder, drummer, peen hammer mechanism trunk With the destruction of the bearing drunk poz.830 rotary motion of the intermediate shaft can not be transformed into translational movement of the cylinder in the impact mechanism.Įliminated by the complete replacement of the rolling bearing. Kit rubber O-rings to the Hammers Bosch 2-26 Collapsed cage of the rolling bearing (drunk bearing) The fault is eliminated by replacing said rubber rings new.įor any repair hammers, his hosts, must be replaced all the rubber products. This cause appears gradual, at least wear rubber rings. Wear rubber rings on the striker, boyke, piston. Now first things first Consider the options, in which the punch does not hollow, but drills there is no power to the electric punch.Cut small teeth on the rotor gear or large gear of the intermediate shaft.The main reasons, in which the punch is not hammer and drill, are: locking mechanism is not holding the instrument in the barrel.locking clip does not capture large gear shaft barrel.The strength of the conical spring, pressing the clutch.Main reasons, in which the hammer drill, but do not drill, this: cut the splines of the clutch, mounted on the intermediate shaft.collapsed cylinder, the firing pin striking mechanism barrel.striker worn rubber ring, hammer, piston.The puncher does not hollow under load or idle for the following reasons: Other models, such as Bosch 2-20, 2-24, construction differ countershaft, installing various drunken bearings. When the mechanical fault in the instrument stranger unpleasant sound appears, enhanced sparks in the collector region, there is a smell of burning, unnecessarily heated tool, its capacity decreases depending on the duration of work and the impact on the material.Īll faults, consider the diagram Hammers Bosch 2-26. Next, we consider the fault of their membership, dividing by the malfunction of mechanical and electrical. continuous operation without interruption Ĭonventionally, failure can be divided into mechanical and electrical.heavy loads at work on the working bodies when chiselling or drilling.The main reasons for the appearance of breakages are: Below we offer you a guide to detect faults in the Bosch rotary hammers and methods of their elimination. But any failure can be repaired with their own hands, if you have a detailed guide for repair works. And the most reliable Bosch rotary hammers begin to break down over time. Common electrical problems Hammers Bosch 2-26.Consider the options, in which the punch does not drill or hammer. ![]() Consider the options, hammer drills in which, but do not hammer.Consider the options, in which the punch does not hollow, but drills.
