1010320FD080 Oil Filter is a spin-on lubrication filter for JAC HFC4DB2-1D diesel engine lubricating circuit. It traps metal wear debris, carbon sludge and circulating impurities inside engine oil, maintaining lubricant cleanliness to reduce friction of crankshaft, bearing and valve train components. This aftermarket replacement filter solves accelerated cylinder liner abrasion, oil passage clogging and bearing damage caused by filter clogging, filter medium rupture and seal leakage. Built-in anti-drain back valve ensures instant oil supply during cold startup, lowering dry wear risk for JAC light trucks that frequently run city stop-and-go delivery and short-haul cargo transport routes.

Product Advantages High-capacity composite filter paper delivers good heat resistance and high dirt holding capacity. Internal anti-drain back valve prevents oil backflow after engine shutdown. Reinforced inner support cage avoids filter collapse under fluctuating oil pressure. Every oil filter undergoes sealing and pressure testing before shipment, OEM thread and sealing gasket support direct spin-on installation during routine maintenance.

Applicable Models Fit for JAC light commercial vehicles equipped with HFC4DB2-1D diesel engine, widely used for township logistics and local cargo delivery fleets.

FAQ

Q1: What risk exists if the bypass valve opens constantly?
A1: Unfiltered dirty oil flows directly, accelerating abrasive wear on bearings and cylinder liner.
Q2: Why should you wipe the sealing surface before installing this oil filter?
A2: Old gasket residue or dirt leads to seal failure, oil leakage and oil pressure loss.
Q3: What maintenance tip helps extend filter service life?
A3: Follow factory drain interval and always use qualified engine oil with correct viscosity grade.
