3802104 — Piston Kit Sa3802104 For Volvo Excavator Ec140

This piston kit is a fundamental component of the engine's reciprocating assembly, converting the pressure from combustion into rotational force. It includes the piston, rings, and often a piston pin, designed to precise dimensions for optimal sealing and heat transfer within the cylinder bore. Manufactured to high-grade material specifications, this new kit ensures superior sealing and durability compared to a worn piston with compromised ring grooves or a scored skirt. Operators may notice a significant loss of engine power, increased oil consumption, or rough engine running if a piston fails.

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

Initial symptoms of a failing piston can include increased exhaust smoke (blue or black), a noticeable drop in engine power, or a knocking sound from the affected cylinder. If left unaddressed, this can lead to excessive oil consumption, cylinder wall damage, and potential connecting rod failure. Continued operation risks severe internal engine damage.

Installation Tip

Carefully clean the cylinder bore and ensure the piston skirt is lubricated with clean engine oil before insertion. Avoid using excessive force when inserting the piston into the cylinder to prevent damage to the piston or rings.

Service Note

Always inspect cylinder liners and connecting rod bearings for wear when replacing piston kits.
