Engine Piston Liner Aftermarket D1402 V1902 85mm Semi‑finished

Description

Product Overview

The Engine Piston Liner from Aftermarket is a precision‑engineered component designed specifically for D1402 and V1902 engine families. With an 85mm bore diameter, this semi‑finished liner provides a solid foundation for custom machining, allowing technicians to bore to exact specifications required by a wide range of equipment. Constructed from high‑strength alloy steel, the liner offers excellent wear resistance and thermal stability, ensuring long‑term reliability even under demanding operating conditions. The design incorporates a smooth inner surface that reduces friction and promotes efficient combustion, while the outer geometry matches OEM dimensions for a seamless fit within the engine block. This product is listed as #50 in the Automotive Replacement Engine Piston Liners category, reflecting its popularity among professionals seeking a dependable replacement part. It is not discontinued, and the manufacturer label “Aftermarket New” guarantees that you receive a fresh, unworn component ready for installation.

Usage

Ideal for both new builds and engine refurbishment projects, this piston liner excels in applications such as Kubota V1902, T133, T173 PLUS, as well as Scat Trak models S1350, 1300HD, and 1650. Whether you are restoring a compact utility vehicle, a mid‑size tractor, or a heavy‑duty construction machine, the liner provides the necessary durability and performance. The semi‑finished state means the part can be customized on‑site, allowing you to match the exact bore size required after wear analysis. It is particularly useful in environments where engines are subjected to high loads, frequent start‑stop cycles, and elevated temperatures, such as agricultural fields, construction sites, and off‑road operations. Proper installation involves boring the liner to the target diameter, cleaning the mating surfaces, and securing it with the appropriate torque specifications to prevent distortion.

FAQ

What does “semi‑finished” mean for this piston liner?

“Semi‑finished” indicates that the liner has been manufactured to a close‑tolerance size but still requires final boring to achieve the exact bore diameter needed for your specific engine. This allows you to tailor the liner to the wear pattern of the existing block, ensuring a precise fit and optimal performance.

Can this liner be used in engines other than D1402 and V1902?

While the liner is optimized for D1402 and V1902 engine families, it can be adapted to other engines that share the same bore dimensions and block specifications, provided that proper machining and fitment procedures are followed. Always verify compatibility with the engine manufacturer’s guidelines before installation.

What machining equipment is recommended for boring this liner?

We recommend using a high‑precision CNC boring machine or a dedicated engine block boring tool with adjustable depth control. The equipment should be capable of maintaining tolerances within ±0.02 mm to ensure the liner seats correctly and operates without excess clearance.

How do I ensure the liner remains properly aligned during installation?

Use alignment pins or a jig specifically designed for piston liner installation. Apply a thin layer of high‑temperature engine assembly paste to the outer surface to prevent galling, and torque the retaining bolts to the manufacturer’s specifications in a criss‑cross pattern to avoid distortion.

What warranty does Aftermarket provide for this piston liner?

Aftermarket offers a limited one‑year warranty covering material defects and manufacturing flaws. The warranty does not apply to damage caused by improper installation, machining errors, or use outside of the specified engine applications.
