DAYUAN 28-piece pneumatic diesel injector puller kit — air-vibration tool with 19 adapters

DAYUAN 28-piece pneumatic diesel injector puller kit is an air-driven vibration tool and adapter set designed to remove seized or tightly fitted common-rail injectors quickly and safely.

This professional-grade kit combines an air-powered vibration tool with a wide selection of adapters and extractor hooks compatible with Bosch, Delphi and Siemens common-rail injectors that use solenoid or threaded connections. It delivers controlled vibration plus 20–30 Nm equivalent torque at recommended working pressures (5–8 bar), helping technicians extract injectors without hammering or damaging the cylinder head. The set includes the vibration unit, hose and plug, three different puller hooks and nineteen adapters to fit a broad range of injector shapes and styles.

How does the pneumatic vibration tool free stuck injectors?

The DAYUAN tool applies rapid air-driven oscillations to break the adhesive and corrosion bond around the injector while offering a steady pulling action. This vibration reduces the force needed for extraction and lowers the risk of damaging the injector bore compared with brute-force methods.

• Air-powered vibration at recommended 72–116 psi (5–8 bar)
• Delivers 20–30 Nm effective loosening action
• Compatible adapters for solenoid and screw-style injectors
• Three puller hooks for different engagement angles

Which injectors and engines will this kit fit?

The adapter set is built to work with a wide range of Bosch, Delphi and Siemens common-rail injectors found in many diesel passenger cars, vans and light commercial vehicles. Adapters cover common interface shapes so you can match the correct sleeve or collar to the injector body before pulling.

• Includes 19 adapters for multiple injector profiles
• Suitable for solenoid-type and screw-connection injectors
• Intended for common-rail systems on light diesel engines
• Adapter identification simplifies correct selection

What safety and performance details should I know?

Operate the tool at the manufacturer’s recommended air pressure and secure the vehicle and injector area before use. The vibration technique reduces impact stresses, but correct adapter seating and hook selection remain essential to prevent slippage or cosmetic damage to the injector body.

• Working pressure: 72–116 psi (5–8 bar)
• Includes air hose and quick-connect plug for workshop compressors
• Three extractor hooks to match different removal angles and depths
• Use firm, controlled pulling—avoid excessive lateral force

What comes in the package and how does it streamline workshop jobs?

The kit organizes a vibration tool and all common adapters and hooks into one set so technicians have the right interface on hand for most injector removal tasks. It reduces time spent swapping improvised fixtures or resorting to destructive extraction methods.

• 1x air vibration removal tool (main unit)
• 1x air hose and 1x air plug for compressor connection
• 19x adapters covering Bosch, Delphi, Siemens profiles
• 3x puller hooks for various extractor geometries

Who is this for? Automotive technicians, diesel specialists and experienced home mechanics who regularly service common-rail diesel engines will appreciate the DAYUAN kit’s time-saving, non-destructive approach to injector removal. It’s best used by operators familiar with compressed-air tools and injector-service procedures who need a compact, adaptable solution to handle seized or hard-to-remove injectors safely.
