DAYUAN Pneumatic Diesel Injector Puller Kit 28‑Piece — Air Vibration Tool, 19 Adapters & 3 Hooks (72–116 psi)

DAYUAN's 28-piece pneumatic diesel injector puller kit is an air-powered removal set designed to extract tight or seized common-rail injectors quickly using vibration and puller adapters.

This professional-grade kit combines an air vibration tool, a selection of adapters, and puller hooks to tackle stuck injectors on engines fitted with Bosch, Delphi, and Siemens common-rail systems. The tool converts compressed air into controlled vibrations and delivers 20–30 Nm of torque at recommended working pressures, helping free injectors without damaging the housing or surrounding components when used correctly. The set is organized to cover solenoid and screw-style connections and comes with everything needed for a single-operator extraction job.

How does this kit free a stuck diesel injector?

The pneumatic tool generates rapid vibration at the injector seating while applying rotational torque, breaking up corrosion, carbon, and deposits that bind the injector in the bore. Vibration reduces friction and mechanical resistance so the included puller hooks can lift the injector out smoothly.

• Air-powered vibration combined with 20–30 Nm torque for controlled extraction.
• Working pressure 72–116 psi (5–8 bar) matches common shop compressors.
• Three puller hooks allow direct mechanical lifting once the injector is loosened.
• Adapters match solenoid and screw-style common-rail injector fittings.

Which injectors and vehicles will these adapters fit?

The adapter assortment is intended for many Bosch, Delphi and Siemens common-rail injectors, covering popular solenoid and screw-connection types. It won’t fit every model, so confirm the adapter shape and thread with your injector before use.

• 19 adapters provide a wide range of contact faces and thread fits.
• Suitable for most common-rail diesel injectors from Bosch, Delphi, Siemens.
• Adapters handle both solenoid-style and screw-connection injectors.
• Inspect adapter-to-injector contact to avoid mismatches or slippage.

What are the key kit components and technical specs?

The kit contains the air vibration tool plus hose and fittings, a broad adapter set, and three puller hooks to complete typical removal jobs. The tool operates at 72–116 psi and produces enough torque and vibration for stubborn injectors without requiring excessive force.

• 1× air vibration tool, 1× air hose, 1× air plug for immediate setup.
• 19× adapters to cover many injector types and 3× puller hooks included.
• Operational pressure 72–116 psi (5–8 bar); torque output around 20–30 Nm.
• Designed to work with standard shop compressors and fittings.

How should I use the tool safely and effectively?

Use recommended air pressure and correct adapter match to avoid damaging injectors or bores. Secure the surrounding area, follow torque guidelines, and remove injectors with steady upward motion once vibration has loosened them.

• Set compressor to 72–116 psi before operating the vibration tool.
• Select an adapter that seats snugly against the injector connection.
• Apply vibration and controlled torque; then lift with a puller hook.
• Wear eye and hand protection and keep work area clean of debris.

Who is this kit for? The DAYUAN 28-piece pneumatic injector puller is aimed at professional mechanics, fleet maintenance technicians, and experienced DIYers who service diesel common-rail engines. It’s most useful where injectors are corroded, carbon-seized, or otherwise difficult to extract using standard hand tools. If you require broad adapter coverage and an air-powered method to minimize force on the injector bore, this kit supplies the components and performance needed for reliable removal jobs. Always verify adapter compatibility with your injector model and follow safe shop practices during use.
