238-2716 Piston Skirt — Cat 320B

This is a piston skirt, a critical component of the piston assembly that guides the piston within the cylinder bore and helps seal the combustion chamber. It is manufactured to meet precise OEM tolerances, ensuring proper fit and function compared to a worn or damaged skirt. Operators may notice increased blow-by, a drop in compression, or unusual engine noises if the piston skirt is failing.

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

Early signs of a failing piston skirt include increased blue-tinged smoke from the exhaust, indicating oil is entering the combustion chamber. If left unaddressed, this can lead to a gradual loss of engine power and increased oil consumption. Continued operation risks significant cylinder wall and piston damage, potentially requiring a full engine rebuild.

Installation Tip

Ensure the cylinder bore is clean and free of any scoring or debris before installing the piston with its skirt. Avoid applying excessive force when seating the piston, as this can damage the skirt or piston itself.

Service Note

Inspect the cylinder walls for wear or damage and check the connecting rod bearings when replacing a piston skirt.
