Product Overview

The P11 Basket Plunger Element 134110-1220 (U461) is a precision-engineered plunger and barrel assembly designed for diesel fuel injection pumps used in heavy-duty industrial and marine applications. Manufactured to exact OEM tolerances, this assembly ensures optimal fuel delivery, atomization, and combustion efficiency in high-pressure injection systems.

We supply this component to diesel engine repair workshops, fuel injection specialists, and fleet maintenance operations across North America, Europe, Asia-Pacific, the Middle East, and Africa. With established export channels and consolidated shipping to major industrial ports, we support both small-volume replacement orders and bulk procurement programs.

FAQ

Q1: How do I confirm this plunger and barrel assembly will fit my injection pump?

A: Check the part number stamped on your existing plunger element or the pump nameplate. This assembly replaces 134110-1220 / U461 and is used in PS and PW2000 series pumps. If you are unsure, send us your pump model and serial number, and our team will verify compatibility before you order.

Q2: What is the recommended installation procedure for this plunger and barrel?

A: Installation should be performed by a qualified fuel injection technician in a clean environment. The plunger and barrel are a matched set and must not be interchanged with other units. Ensure all fuel lines and pump internals are free of debris, use clean calibration fluid during reassembly, and torque retaining components to OEM specifications. Always replace seals and O-rings during reassembly.

Q3: How should I maintain this component to maximize service life?

A: Use clean, water-free diesel fuel and replace fuel filters at recommended intervals. Contaminated fuel is the leading cause of plunger and barrel wear. For engines in storage, use a fuel stabilizer and periodically rotate the pump to prevent corrosion. Inspect injection performance regularly and replace the element at the first sign of reduced power, rough idle, or increased fuel consumption.
