294-1722 Piston Cooling Oil Jet — Cat 3066 311D

This piston cooling oil jet is an essential part of the engine's lubrication system, spraying oil onto the underside of the piston to dissipate heat and lubricate the piston pin. Manufactured to precise specifications, it ensures consistent oil flow and spray pattern, unlike a clogged or damaged jet. Operators may notice increased engine temperatures, abnormal engine noise, or reduced engine performance if this jet is not functioning correctly.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a faulty piston cooling oil jet might be a slight increase in engine oil temperature. If the issue progresses, the engine may start to exhibit knocking sounds due to increased piston-to-cylinder temperatures. Continued operation without addressing this can lead to severe piston and cylinder damage.

Installation Tip

Ensure the oil passages leading to the jet are clean and free of any obstruction before installation. Do not overtighten the jet, as this can damage the threads in the engine block.

Service Note

Inspect the piston crown for signs of overheating and check the cylinder liner for scoring when replacing the piston cooling oil jet.
