Product Description
Brand new, high-quality Piston 3801819 for 855 series engines
Piston 3801819 is a forged high-silicon aluminum piston for turbocharged diesel engines, widely used for overhaul of heavy construction machinery and generator sets. It has five core features:
- Offset optimized combustion bowl. The offset chamber matches injector spray angle to organize steady fuel swirl. It avoids over-rich local combustion and carbon buildup, and keeps consistent combustion efficiency under variable load conditions.
- Graded hardening treatment for ring grooves. Hardening thickness varies for the three grooves. The top groove, exposed to the highest temperature, gets thicker reinforced coating to resist wear and maintain proper ring clearance for sealing.
- Diamond-shaped oil retention texture on skirt. Interlaced diamond grooves trap lubricant to form stable oil film. It eases boundary friction during start-up and greatly reduces scuffing risk when the engine is cold.
- Precision honed wrist pin bore. The inner surface of pin hole is finely honed for low roughness. Smooth contact distributes alternating load evenly and prevents fatigue cracks caused by continuous machine vibration.
- Dual sorting of dimension and weight. Combustion bowl volume, skirt profile and pin bore concentricity are inspected. Pistons are sorted by weight with tight tolerance limits. It guarantees good dynamic balance and reduces engine vibration.
This aftermarket piston has excellent interchangeability. It can be sold separately or as a full kit including piston pin, circlips and piston rings. Matched with cylinder liner kits, it delivers reliable durability under heavy-duty mining and construction site conditions.
