Fuwa Trailer/Dump Truck Engine Fuel Filter CX0708 Oil Filter JX0810B / WB202
Core Materials and Internal Manufacturing Processes
1. CX0708 Diesel Filter: The housing is made of cold-rolled, deep-drawn steel with an anti-corrosion electrostatic spray finish; internal filter element end caps typically utilize galvanized steel to prevent internal corrosion caused by acidic substances in the fuel.
2. JX0810B / WB202 Oil Filter: Features excellent resistance to high temperatures and acids (remains structurally sound-without softening, becoming brittle, or perforating-after prolonged immersion in 135°C engine oil).
Core Valve Structures:
Anti-Drainback Valve: Made of high-quality silicone rubber, this valve instantly seals the oil inlet when the engine is turned off, retaining oil within the filter. This ensures rapid oil delivery to the cylinder head during the next cold start, preventing momentary dry friction.
Bypass Valve: Controlled by a precision coil spring. If the filter medium becomes severely clogged due to missed maintenance or if the oil becomes excessively viscous in winter, the valve automatically opens. This allows unfiltered oil to flow directly into the main oil gallery, protecting the engine from catastrophic failure (such as bearing seizure) caused by oil starvation.
Installation and Sealing Specifications
1. Standard Thread Alignment:
CX0708 standard internal thread: M16 × 1.5 - 6H; effective thread depth ≥ 12 mm.
JX0810B standard internal thread: M20 × 1.5 - 6H; effective thread depth ≥ 14 mm.
2. Standard Manual Installation Procedure: Before installation, apply a layer of clean engine oil or diesel fuel to the surface of the filter's rubber gasket. Screw the filter on clockwise until the gasket makes initial contact with the filter base. Then, firmly tighten it an additional 3/4 to 1 full turn by hand or using a dedicated filter wrench.
Recommended Service Life and Replacement Intervals
1. Standard Operating Conditions (e.g., indoor warehouse forklifts, indoor generator sets): Replacement is recommended every 250 to 300 operating hours, or in pairs alongside the vehicle's engine oil maintenance.
2. Severe Operating Conditions (e.g., excavators on dusty construction sites, tractors used for field cultivation): Mandatory replacement is recommended every 150 to 200 operating hours. Particular attention should be paid to the diesel filter (CX0708); if restricted fuel flow or a loss of machine power is detected, inspecting and replacing this filter should be the priority.
