Engine Piston
The engine pistons supplied by JY Construction Parts are forged components intended for a broad selection of diesel engines used in construction and material‑handling equipment. The catalogue lists compatibility with models such as Komatsu 4D95K, Mitsubishi 4D30, Isuzu 4BA1 and Yanmar 4TNE88, among many others. Each piston is machined to the bore dimensions specified by the original equipment manufacturer and includes the piston pin and wrist pin groove. The parts are produced in Jining, China and shipped directly from the factory.
Pistons for diesel engines are commonly forged from aluminium‑silicon alloy, a material typical for its high thermal conductivity and strength‑to‑weight ratio. The typical bore range for the listed engines is 80 mm to 120 mm, with a standard weight of 1.2‑2.5 kg per piston. Surface finish is usually Ra 0.4 µm, meeting the tolerance standards typical for high‑performance diesel applications. The supplier follows standard machining tolerances of ±0.02 mm on diameter and ±0.1 mm on pin length.
These pistons are purchased by OEMs, rebuild shops and large‑scale equipment distributors who require reliable replacement parts for fleet maintenance. Trade terms are arranged on a bulk basis, with buyers expected to discuss FOB or CIF conditions and settle payment via bank transfer. Prospective buyers should request a technical data sheet, confirm the exact engine model, and verify the supplier’s capacity before committing to a large shipment.

Sourcing Engine Piston from JY Construction Parts - China Import Guide
Before ordering, confirm the exact engine model, bore size and any required certifications such as ISO 9001 compliance. Request a technical data sheet and, if possible, a sample piston to verify fit and finish. Because the supplier’s response rate is listed as 0.00, establish clear communication channels and set expectations for reply times.
Logistics are usually organised on an FOB basis from a Chinese port, with buyers specifying Incoterms such as CIF or DAP as needed. Discuss container loading plans, lead‑time estimates and payment terms, typically a bank transfer after document presentation. Obtain a shipping schedule from the supplier to align with your production timeline.
Quality control includes dimensional inspection, surface‑finish measurement and material composition testing. Importers should ask for a material test report, a dimensional inspection certificate and, if required, a heat‑treatment verification. Conducting an independent inspection at the port of loading can provide additional assurance that the pistons meet the agreed specifications.
