DUP158914 VALVE,VACUATOR – Komatsu FD40-FD80 Forklift Part

Overview

The DUP158914 VALVE,VACUATOR is a Komatsu replacement valve used in the air intake system of -10 series internal combustion forklifts. Mounted on the precleaner, this vacuator valve continuously ejects dust, dirt and moisture separated from incoming air, keeping the air cleaner element from loading up prematurely and helping to protect the engine against abrasive contamination. A cracked, hardened or clogged valve can no longer perform this self-cleaning function, allowing debris to build up in the dust cup and reducing intake efficiency. Fitting a new DUP158914 valve restores proper dust ejection and supports consistent engine performance in demanding material handling environments.

Compatibility

This Komatsu vacuator valve fits a wide range of -10 series diesel and gasoline forklifts:

• FD40/45/50 diesel series: DUP158914 for FD40-10-US, FD40Z-10-US, FD45-10-US and FD50A-10-US
• FD60/70/80 diesel series: FD60-10-US, FD70-10-US and FD80-10-US
• Gasoline model: FG40-10-U-US

Model codes can vary by chassis revision, so always verify the part number on your forklift’s serial plate or in your parts manual before ordering. If you are unsure whether this valve matches your machine, our parts specialists can help you confirm fitment.

Quality and Reliability

This replacement valve is produced to match Komatsu’s original design for fit, form and function, so it lines up with existing mounting points without modification. The valve body is engineered to withstand constant flexing, engine vibration and exposure to dust and moisture—conditions typical of construction sites, warehouses and yards. Choosing the correct Komatsu-specified vacuator valve rather than a generic substitute helps maintain the air system’s performance and avoids repeat replacements.

Installation and Maintenance Tips

The vacuator valve is a simple service item, but correct fitting matters:

• Replace the vacuator valve during scheduled air cleaner service, or sooner in dusty applications.
• Inspect the old valve for cracks, hardening, splits or blockages before fitting the new one.
• Seat the valve fully and confirm correct orientation so the ejector action works as designed.
• Check the dust cup and precleaner body for accumulated debris and clean as required.
• Keep the DUP158914 part number on file for faster reordering.
