Brand New Weichai Series Wp12.420 Mechanical Pump Engine For Dump Trucks

As Weichai's dedicated power solution for heavy-duty applications, the WP12.420 mechanical pump engine for dump trucks stands out with its exceptional durability and adaptability, making it the core power choice for dump trucks in mining sites, construction sites, and similar environments. Keluo Construction Machinery supplies brand-new genuine models, and mastering scientific maintenance methods is essential to maximize the engine's service life.

The Weichai WP12.420 mechanical pump engine for dump trucks features a fuel system with a simple structure and strong resistance to contaminants. It requires no complex electronic controls, resulting in lower failure rates in dusty construction sites with unstable voltage. This design perfectly aligns with the operational characteristics of dump trucks, which involve frequent starts and stops under high-load conditions.

Kelu Company sells Weichai series WP12.420 mechanical pump engines for dump trucks, all verified as genuine factory products and subjected to professional performance testing to ensure all parameters meet standards upon delivery. Leveraging Kelu's parts supply system, we provide compatible spare parts support for subsequent maintenance, making procurement and upkeep more hassle-free for users. After purchase, perform the following maintenance based on dump truck operational characteristics:

First, implement regular basic maintenance. Use Weichai-specified CI-4 or higher grade engine oil with 15W-40 viscosity, changing it every 5,000 kilometers or 6 months. Heavy-duty dump truck operations accelerate oil degradation, and exceeding maintenance intervals increases component wear. Replace the oil filter and fuel filter simultaneously. The fuel filter is particularly critical, as mechanical pumps are sensitive to fuel impurities. Inspect it every 2,000 kilometers. If diesel fuel contains high impurity levels, shorten the replacement interval to prevent impurities from wearing down the pump plungers.

Second is specialized maintenance for mechanical pumps. Monthly inspections should check the fuel injection timing angle of the mechanical pump. If difficult starting or reduced power is observed, adjust to the manufacturer's specified angle (typically 12-14°). Weekly checks should verify the seal integrity at the pump body and fuel line connections to prevent fuel leakage. Every three months, disassemble and clean the pump body filter screen to prevent impurities from clogging the fuel passages.

Additionally, perform condition-specific maintenance. Dump trucks frequently operate in dusty environments. Inspect the air filter every 1,000 kilometers. Surface dust can be blown off with compressed air. Replace the filter immediately if the paper element is damaged or clogged to prevent sand and dust from entering the cylinders and scratching the cylinder walls. Cooling system: Weekly coolant level checks are required. Add antifreeze (never use tap water). Clean external radiator dust and internal scale deposits every six months to prevent engine overheating during heavy-duty operations.

Lastly, daily inspections are essential. Before driving, check the oil dipstick level (must be checked when the engine is cold, between the upper and lower markings) and the coolant reservoir level. After operation, inspect the engine for oil or fuel leaks and listen for abnormal noises during operation. Monthly tighten the engine-to-chassis mounting bolts to prevent vibration-induced component loosening.

Scientific maintenance is key to the stable operation of the Weichai series WP12.420 mechanical pump engine for dump trucks. By utilizing genuine new engines and compatible parts supplied by Keluo, combined with standardized maintenance, the engine can sustain high efficiency under the demanding conditions of dump truck operations, thereby reducing operational and maintenance costs.
