404D-22 Cylinder Liner for Perkins Engine Parts – Diesel Engine Liner

Product Details

Product Overview

This high-quality cylinder liner is specifically designed for the Perkins 404D-22 diesel engine, a popular model widely used in construction, industrial, agricultural, genset, marine, and material handling applications. Manufactured to OEM specifications, this liner ensures a precise fit and reliable performance within your Perkins engine block.

Crafted from durable materials, the 404D-22 cylinder liner provides a hardened wear surface for the piston rings, essential for maintaining compression and reducing oil consumption. As a critical component of the engine’s combustion chamber, a properly fitted liner is vital for optimal engine efficiency and longevity. This part is an ideal replacement for worn or damaged liners, helping to restore your Perkins engine to its original operating condition.

Key Features & Benefits

• OEM Specification Fitment: Manufactured to the exact size and tolerances of the original Perkins 404D-22 cylinder liner, ensuring a seamless installation and reliable sealing.

FAQ

Q1: How do I confirm this cylinder liner fits my Perkins 404D-22 engine?
A: This liner is manufactured to the OEM specifications for the Perkins 404D-22 engine model. To ensure a perfect fit, we strongly recommend checking the part number on your current liner or your engine’s serial number. The standard size liner is for engines that have not been previously overbored. If your engine block has been machined, you may require an oversized liner.

Q2: What is the correct installation procedure for this cylinder liner?
A: Installation of a cylinder liner is a precision task. The liner should be clean and lightly oiled before being carefully pressed or guided into the engine block using a proper installation tool. Never hammer the liner directly. After installation, the liner protrusion (height above the block deck) must be checked with a dial gauge to ensure it is within the engine manufacturer’s specified range. We recommend having this work performed by a qualified diesel engine mechanic.

Q3: What maintenance is required after installing a new cylinder liner?
A: After installation, the engine must be properly broken in. This typically involves running the engine at varying loads (avoiding prolonged idling) for the first 50-100 hours. During this period, the piston rings will seat against the new liner surface. It is crucial to use the correct grade of engine oil and change it according to the Perkins maintenance schedule after the break-in period to remove any initial wear particles. Always monitor coolant and oil levels closely after a major repair.
