Connecting rod kit for oil-free silent compressor pump

A metallic knocking in the pump, unusual vibrations or a compressor that delivers less air even though the motor turns normally: these are the typical symptoms of a worn connecting rod. With this connecting rod kit you can repair it yourself and the compressor works smoothly and at full air flow again.

It is the spare for the AP1100 (PRO103SILENT compressor) and AP1500 (PRO104 and PRO204 compressors) oil-free silent pumps. An inexpensive repair that saves replacing the whole pump.

As these are oil-free pumps, the condition of the connecting rod is key: with play, the piston runs off-centre and wears the ring and cylinder sooner.

✅ Key benefits

  • Eliminates knocking: corrects play caused by wear.
  • Restores air flow: the piston works properly again.
  • Two versions: AP1100 and AP1500.
  • Inexpensive repair: without replacing the whole pump.
  • Oil-free pumps: specific to silent units.

🏗️ What it's for

  • Repairing AP1100 pumps on the PRO103SILENT.
  • Repairing AP1500 pumps on the PRO104 and PRO204.
  • Fixing noise and vibration in the pump.
  • Maintenance of silent compressors.

📋 Technical specifications

  • AP1100: for PRO103SILENT compressor
  • AP1500: for PRO104 and PRO204 compressors
  • Pump type: silent, oil-free
  • Contents: connecting rod kit

💡 Vetonek tip: if you replace the connecting rod, take the opportunity to check the piston ring and seals and the valve plate: the pump is already open and the cost of the kit is small. Always work with the compressor disconnected and the tank empty.

Frequently asked questions

How do I know if the connecting rod is faulty?

Metallic knocking in the pump, abnormal vibration or loss of air flow while the motor turns normally.

Which one do I need?

The AP1100 for the PRO103SILENT and the AP1500 for the PRO104 and PRO204.

What else is worth replacing at the same time?

Check the piston ring and seals and the valve plate, which also have replacement kits.

Can I fit it myself?

With mechanical experience, yes. Disconnect the compressor and drain the tank before opening the pump.

Is it suitable for lubricated pumps?

No, it is for the AP1100 and AP1500 oil-free silent pumps.
