Karlsruhe/Plochingen (Germany) – At several common rail systems, the injectors are installed into sleeves. In this manner, they are detached from the cylinder head. Installed onto the injector, a snap ring pushes against this sleeve from the inside thus keeping the injector in position. In case an injector is to be removed for inspection or because it is defective, this sleeve is removed as well. At the disassembly, the snap ring is usually bent and has to be replaced. A new Bosch tool set now allows safe disassembly and assembly of the snap ring within seconds. Even replacement injectors installed in exchange for defective common rail injectors often come without sleeve. In these cases, the sleeve is to be disassembled first in order to install it onto the replacement injector. The sleeve is then fitted by means of a new snap ring which can easily be installed using the snap ring tool.

Suitable for more than ten million vehicles worldwide

So far, the new Bosch tool set for safe disassembly and assembly of injector snap rings is the only set of its kind available on the market. It can be used to work on injectors of vehicles of the BMW, Fiat and PSA groups worldwide – and for a vehicle stock exceeding 10 million vehicles.

Practical workshop set including disassembly and assembly tool

The new Bosch snap ring tool prevents both injuries and injector damage. It allows workshops to save a lot of time and money. Especially since down to the present day, workshops often use unsuitable tools to remove the snap ring from the injector. Disassembly by means of pliers, however, is very likely to damage the injector. In case a workshop employee tried to remove the snap ring by means of a screwdriver, he could even slip off and harm himself. The new Bosch spring ring set consists of a disassembly and an assembly tool and is supplied as a practical workshop set.
