The best puller for reverse hammer nozzles - TOP-5 options
Content
To dismantle diesel fuel injection injectors that are strongly attached to the cylinder head, considerable effort is required. To do this manually is difficult, inconvenient, and often simply impossible. However, the pneumatic blowback hammer for injectors provides effective independent dismantling of injectors from a diesel engine for maintenance and repair. The limited space of the powertrain compartment is not a hindrance for a pneumatic extractor.
Pneumatic reverse hammer for removing injectors, according to reviews, is the best tool for dismantling them in case of sticking to the cylinder head. The decision to make a choice in favor of its application will greatly facilitate the work.
Diesel injector puller with reverse hammer
A specially designed mechanism is used for dismantling diesel fuel injectors of engines assembled according to Mercedes technology with a common rail OM611, OM612, OM613. It is convenient to use in the repair and maintenance of the injection unit.

The pull-out force is formed by transferring the energy of the impact of the weight, directed upwards, to the nozzle end switch. This ensures its extraction from the coked mine without removing the cylinder block.

To dismantle diesel fuel injection injectors that are strongly attached to the cylinder head, considerable effort is required. To do this manually is difficult, inconvenient, and often simply impossible. However, the pneumatic blowback hammer for injectors provides effective independent dismantling of injectors from a diesel engine for maintenance and repair. The limited space of the powertrain compartment is not a hindrance for a pneumatic extractor.

Small dimensions allow easy access and quick removal. Due to the high frequency of the push-off impact, the extraction of the entire set of diesel injectors occurs in a few minutes. To start, compressed air is used, supplied through the line at a pressure of 7,5-8,5 atmospheres. The low weight of the device (just over 1 kg) and compact design contribute to unhindered access to the nozzles removed from the motor.

The tool is equipped with two suction cups of different sizes for secure fixation on the straightened surface. Designed for straightening car bodies, tin works and other measures to correct or form a given curvature in the treated area.

The principle of operation of such a device is to create a shock or push force from the inside. For this, a mechanism is used to attach one end of the hammer to the surface using a vacuum suction cup. On the other side there is a thrust washer, under which blows are applied by a load sliding along the guide rod.
At the end of the work, the suction cup is separated from the surface by closing the compressed air supply valve. The tool comes with the following:
- bearing rod of the reverse hammer assembly with a movable impact weight;
- round rubber suction cups with a diameter of 115 mm and 155 mm with a threaded hole for attaching to the end of the axle;
- hose with removable fitting for connection to the compressed air supply line;
- ball valve with lever control vacuum suction cup.
Diesel injector puller Mercedes CDI with reverse hammer with two jaws
The operation of a diesel engine without regular maintenance or when using untested fuel quality leads to sticking of the injector bodies to the inner walls of the landing shaft. This makes it very difficult to carry out preventive measures (cleaning, adjustment).

A special tool will help here, which can be used to independently remove the injectors without dismantling the cylinder head. According to its characteristics, this universal kit is suitable for servicing Mercedes Common Rail Diesel Injector (CDI) power units and is presented in the following composition:
- ﬤ- and ʃ-shaped grips;
- guide for the movement of the impact weight;
- hammer head in the form of a disk with a groove for fingers;
- extension;
- adapter for threaded attachment to the injection regulator.
You can buy a reverse hammer for injectors for use on all Mercedes common rail diesels (CDI).
Universal injector puller CAR-TOOL CT-V1869
Diesel engines from different manufacturers are united by the fact that, as they work for a long time, the nozzles tend to stick to the cylinder block body. This makes it difficult to dismantle for later maintenance. Specialized devices for quick extraction of diesel injectors are only suitable for certain power units described in the instructions.

In this case, a universal grip can help. After installation, a reverse hammer with a mechanical or pneumatic drive is attached to it. After assembling the entire structure, the nozzle is subjected to impact forces that push it out of the seat.
The universal puller is a single mechanism in which 2 removable paws, working on the principle of a rocker arm, are fixed at different ends of a common head moving along the thread on the rod. The closing force is provided by a conical nut on the opposite side. The device includes a hex adapter for a wrench. To remove the nozzles, you will need a reverse hammer, which you will have to buy separately.
