137mm Hino EK100 Engine Piston 13216-1220/13216-1224 for TD42 Heavy Duty Truck

Product Details

Product Overview

This heavy-duty engine piston assembly, manufactured to OEM specifications, is specifically designed for the Hino EK100 and EK100-T diesel engine platforms. With a precise 137.00mm diameter, this piston is a critical component for maintaining compression and power output in demanding applications such as heavy-duty trucks, marine propulsion, and engineering machinery.

Branded under, this assembly includes the piston, wrist pin, and necessary retaining rings, providing a complete drop-in replacement solution. The part numbers 13216-1220 and 13216-1224 are direct cross-references, ensuring compatibility with original Hino engine configurations. While commonly associated with the TD42 engine model, professional verification against your specific engine block is always recommended before installation.

This piston is engineered to withstand the extreme thermal and mechanical stresses of commercial diesel operation, offering a reliable solution for fleet maintenance, engine overhauls, and rebuild projects.

Key Features & Benefits

• Precision Engineering: Manufactured to a strict 137.00mm diameter tolerance for a perfect cylinder fit, reducing blow-by and maximizing compression efficiency.
• High-Silicon Aluminum Alloy: Constructed from durable aluminum alloy with high silicon content, providing excellent wear resistance and thermal stability under high load conditions.
• Complete Assembly: Supplied as a full piston assembly, including the wrist pin (50.00mm x 110.00mm), ready for installation. This simplifies procurement and ensures all components are matched.
• Advanced Surface Treatment: Features tin plating, phosphating, and an anodized top. These treatments enhance corrosion resistance, reduce friction during initial break-in, and improve heat dissipation from the piston crown.
• Rigorous Quality Control: Each unit undergoes outgoing inspection. A machinery test report and video inspection are available upon request, confirming dimensional accuracy and material integrity.
• Versatile Application: Suitable for the heavy-duty demands of Hino trucks, as well as marine and construction equipment using the EK100 engine series.

FAQ

Q1: How can I confirm this 137mm piston fits my Hino EK100 engine?
A: While this piston is specifically designed for the EK100 and EK100-T models, we recommend confirming two key measurements. First, verify that your cylinder bore diameter is compatible with the 137.00mm piston size. Second, check your existing piston’s pin bore size against our 50.00mm wrist pin. Cross-referencing your old part number against 13216-1220 or 13216-1224 is the most reliable method.

Q2: Does this piston assembly include all necessary rings and the wrist pin?
A: This product is listed as a “Piston Assy” and includes the piston body and the wrist pin (50mm x 110mm). Piston rings are often a separate purchase, as they are wear items that may need to be matched to your specific cylinder condition. Please check the product listing or contact us to confirm if rings are included in your specific order.

Q3: What is the purpose of the different surface treatments on this piston?
A: The tin plating and phosphating treatments serve as a break-in coating, reducing friction between the piston skirt and cylinder wall during the initial hours of operation. The anodized top creates a hard, heat-resistant layer on the piston crown. This protects the aluminum from the extreme temperatures of the combustion chamber, reducing the risk of thermal fatigue and pre-ignition damage.
