The 199014520311 HOWO Balance Shaft Cover is a key protective and sealing part for HOWO heavy-duty trucks' balance shaft assemblies (tractor, cargo, dump trucks). Mounted on the balance shaft's outer end, it seals lubricating oil, blocks dust/debris, and protects internal rotating parts (bearings, gears, shafts) from wear and corrosion. The balance shaft is vital for reducing engine vibration and smooth vehicle operation-so the cover's sealing and protection directly affect the balance shaft's life and the truck's running stability. This avoids balance shaft damage from oil loss or foreign objects.
We use good materials and precision machining to make it: the cover body is high-strength HT200 cast iron-wear-resistant and pressure-resistant. The sealing surface has a high-temperature nitrile rubber gasket-oil-resistant and aging-resistant. Fixing holes have reinforced thread inserts-rust-resistant and torque-resistant. The installation interface, bolt spacing, and fit dimension fit the original HOWO balance shaft assembly (A7/T7H/T5G models with HW series gearboxes) exactly, so it installs with no mods. It handles tough conditions-engine compartment high temps, road vibration, and engine oil/grease corrosion-without cover deformation, gasket aging, or thread damage. Swapping it is easy: no need to disassemble the entire balance shaft, just remove old cover bolts, clean the sealing surface, install the new cover with the matching gasket, tighten bolts to specified torque, and check for oil leakage. Before shipping, we test 'em strict: sealing (no oil leakage at 0.3MPa), torque resistance (bolts withstand ≥200N·m), and durability-so it's reliable.Every user says it works reliably: excellent sealing (no oil leakage during long-term high-speed operation), strong structure, no deformation/cracking/sealing failure even under 2-500Hz vibration and 110℃ high temps.

advantages
①Superior sealing: High-temperature nitrile rubber gasket + precision-machined sealing surface form a tight seal, preventing oil leakage and foreign object intrusion, ensuring balance shaft lubrication stability.
② Strong durability: HT200 cast iron cover + reinforced thread inserts boost strength, resisting deformation/wear-service life 40% longer than ordinary cast aluminum covers.
③ Perfect for HOWO: Made to HOWO's original balance shaft design-installation interface, bolt spacing, fit dimension match. No drilling or gasket mods needed-saves 35% maintenance time vs universal balance shaft covers.
④ Wide adaptability: Resists high temp, oil corrosion, and vibration-maintains stable performance in harsh conditions, ensuring long-term reliability.
Application Scope
This 199014520311 Balance Shaft Cover is only for HOWO heavy-duty trucks-A7, T7H, T5G models with original HOWO balance shaft assemblies (matching HW series gearboxes). It won't work on HOWO with modified balance shaft structures or other brands (FAW Jiefang, Dongfeng Tianlong). Those have different balance shaft dimensions, interfaces, or sealing needs-this balance shaft cover won't fit or work.
FAQ
Q1: Oil leakage after installing new cover?
A1: First check gasket installation (no misalignment/damage). If good, clean balance shaft sealing surface (remove oil/rust/debris). If clean, check bolt torque (tighten to specified value). Still leaking? Replace the cover (rare defect).
Q2: How to maintain the 199014520311 HOWO Balance Shaft Cover?
A2: 1. Check cover/gasket for oil leakage every 25k km (replace gasket if aging/damaged); 2. Clean cover surface often to remove dust/oil/corrosion; 3. Inspect bolts for looseness during maintenance (tighten to specified torque if needed).
Q3: Works on HOWO with modified balance shaft structures?
A3: No-modified balance shafts have different dimensions/sealing needs. It causes mismatched installation or poor sealing, leading to oil leakage and balance shaft wear. Get the balance shaft cover for modified HOWO balance shafts instead.
