Fuel Injection Pump Plunger Element K334 140163-4220 for Bobcat Kubota V2203-MDI Diesel Engine

Fuel Injection Pump Plunger Element K 3 3 4 with the part number 140163-4220 (also cross-referenced as 9 4 1 0 6 1 8 1 2 2). This is a precise and necessary component for the refurbishment of the fuel injection pump on the widely used Kubota V 2 2 0 3-MDI diesel engine, commonly found in various Bobcat skid steer loaders and other compact utility equipment.

The Plunger Element 140163-4220 is the heart of the mechanical injection pump, responsible for generating the high pressure required and accurately metering the fuel charge for each cylinder. Due to continuous operation under high mechanical stress and friction, the plunger assembly eventually wears down. This wear leads to decreased fuel pressure, irregular engine timing, hard starting, and significant loss of power—all critical issues for heavy-duty equipment like Bobcat loaders.

Replacing the worn plunger elements with this new, high-quality component is vital for restoring the fuel pump’s efficiency. Our Plunger Element 140163-4220 is manufactured to strict technical specifications to ensure maximum durability, precise fitment, and accurate fuel delivery, guaranteeing that your Kubota V 2 2 0 3 -MDI engine regains its intended robust performance and reliability.
