For fleet managers and engine repair technicians maintaining modern Sinotruk heavy trucks, matching high-performance filter elements directly cuts long-term engine overhaul costs. Substandard oil filters cannot fully capture metal filings, carbon sludge and abrasive particles generated inside high-power diesel engines, leading to premature wear of crankshaft bearings, pistons and turbo assemblies. Our OEM-grade 1002070370 cartridge-style oil filter is engineered exclusively for HOWO TX, TH7 and SITRAK trucks equipped with Weichai WP10H, WP13H, WP14T and WP15H power units, and it has become a standard maintenance replacement for spare parts dealers operating in Africa, Southeast Asia and Central Asia.
This 1002070370 oil filter adopts a full pleated multi-layer fiber filter paper structure, designed with a large dirt holding capacity to adapt to heavy-load long-distance transportation under dusty and high-temperature working conditions. Many cheap generic filter cores use thin single-layer paper that clogs quickly or tears under fluctuating oil pressure, triggering insufficient lubrication and hidden engine failure risks. Our filter element adds reinforced support ribs on each filter layer, paired with an integrated anti-drainback valve inside the top cap. It locks engine oil inside the filter cavity after engine shutdown, eliminating dry start wear every time you restart the vehicle. The matched thickened rubber sealing ring delivers zero leakage after long-term chassis vibration.
All production of 1002070370 oil filter strictly follows original Weichai OEM dimensional standards, with 114mm outer sealing diameter and standard overall height to fit the factory filter housing without any trimming or gasket modification during replacement. Mechanics can finish filter replacement within minutes during routine oil service, greatly saving workshop labor time. Each finished filter will pass multi-stage pressure resistance, filtration efficiency and leak tightness testing before leaving the warehouse to guarantee stable lubricating oil circulation under full-load climbing and continuous high-speed running.
Three core strengths make our 1002070370 filter popular among global bulk buyers. First, exclusive matching for latest WP13 series high-horsepower engines, compatible with post-2019 HOWO TX and TH7 heavy trucks, no mismatching trouble for export vehicle maintenance. Second, oversized dust storage capacity extends service intervals, reducing filter replacement frequency for large transport fleets. Third, we maintain year-round full stock of 1002070370 filter elements, supporting single-piece retail for small repair shops and tiered discount wholesale for regional distributors, neutral export packaging is available for local resale branding demands.
This 1002070370 oil filter element fits Sinotruk HOWO TX, TH7, SITRAK C7H series trucks with Weichai WP10H/WP13H engines, also suitable for partial Shacman X6000 models carrying the same power platform. It cannot replace spin-on can-type oil filters for older WD615 engines. If you cannot confirm engine compatibility, send your truck VIN or the OEM code printed on your old filter element, our technical team will complete matching verification within 24 working hours.
Regular replacement of qualified oil filters is the most economical way to protect expensive heavy-duty diesel engines. Cutting corners with low-cost filter cores often results in costly engine teardown repairs. Our OEM standard 1002070370 oil filter balances reliable filtration performance and competitive wholesale pricing, serving as the preferred maintenance spare part for global HOWO heavy truck operators.
