HY18B Mini Excavator Internal Structure and Single-Person Maintenance Guide

In this video, we remove the exterior casing of the HY18B Mini Excavator to give you an exclusive look at its internal engineering and premium components. Our goal is to demonstrate the user-centric design that allows for complete maintenance to be performed efficiently by a single operator.

Key Highlights of the HY18B:

Internal Configuration Unveiled: We expose the heart of the machine—the reliable KUBOTA D722 engine (14hp / 722cc displacement). You will see how the hydraulic system, including the 16mpa gear pump, is laid out for easy access.

True One-Man Maintenance: We walk you through the entire maintenance process to prove that you don’t need a team to service this machine. The HY18B is designed to maximize uptime and minimize labor costs.

Crucial Maintenance Tip: Don't miss the first minute of the video where we discuss a vital safety and preservation tip. When the machine is idle, it is imperative to turn off the battery switch. Failure to do so during rain or snow can cause static electricity to react with salts in the precipitation, leading to accelerated corrosion on galvanized parts.

Machine Specifications:

Operating Weight: 1410kg (3108lbs)

Compact Dimensions: Chassis width of 1100mm, perfect for tight spaces.

Performance: Max digging depth of 2170mm with a robust digging force.
