The KOMATSU Diesel Engine Piston Set (part number 6142-32-2120) is an OEM replacement assembly manufactured from an aluminium‑silicon alloy (Al‑Si) and intended for the 4D95 series diesel engines that power KOMATSU construction and material handling machines. The pistons are machined to exacting tolerances and are designed to sustain the high pressures and temperatures typical of heavy‑duty diesel operation, helping to maintain combustion efficiency and engine lifespan.
The alloy composition provides a balance of strength and thermal conductivity that is standard for modern diesel pistons. Industry practice for pistons of this class includes a bore around 115 mm, a stroke near 130 mm, a weight of roughly 1.2 kg, and a three‑ring steel configuration, often finished with a Nikasil coating to reduce wear. These typical dimensions and treatments are applied to ensure reliable performance across a range of KOMATSU models.
The set is most often sourced by equipment maintenance firms, mining contractors and large construction companies that require dependable spare parts for uptime. V‑Tech Auto Parts Industry Corporation offers flexible order quantities, supports FOB and CIF shipping terms and can provide the standard certifications that accompany heavy‑machinery components. Buyers should confirm the exact part number and compatibility with their engine before placing an order.

Before ordering, verify that the aluminium‑silicon alloy composition and the part number 6142‑32‑2120 match the specifications required for your 4D95 engine. Request a material test certificate and a fit‑check drawing to ensure full compatibility with the target equipment.
Discuss logistics early: confirm the expected lead time, choose an appropriate incoterm such as FOB Taiyuan Port or CIF Kaohsiung, and agree on payment terms that suit both parties, typically a letter of credit or advance payment for first orders. Shipping containers are the usual mode for bulk piston sets, and the supplier can arrange palletised packing to protect the components during transit.
Arrange for a pre‑shipment inspection that covers dimensional checks, surface coating integrity and material certification. Upon arrival, ask for a mill test report and a quality assurance certificate. Maintaining records of these documents will help streamline customs clearance and future warranty claims.
