This transmission output shaft cover is specially designed for heavy-duty commercial truck gearboxes, adopting a robust flange-type structural design as the sealing end cover for the gearbox output shaft position. The product is processed through precision CNC machining, with evenly distributed multiple bolt holes arranged in a standard layout, which enables stable, stress-balanced installation and firm locking onto the gearbox housing to avoid loose displacement under long-term high-load driving conditions.
A high-precision sealing groove is pre-machined on the inner fitting surface of the flange, which can perfectly match the standard oil seal to form a tight closed sealing structure. It effectively isolates the internal gear lubricating oil of the transmission from the external driving environment, thoroughly preventing lubricant leakage caused by high-speed rotation, vibration and temperature fluctuation during truck climbing, heavy-load transportation and long-distance cruising.
Besides the core sealing function, this output shaft cover acts as an accurate bearing positioning component. It limits the axial and radial movement of the output shaft bearing, stabilizes the running clearance of the transmission output assembly, reduces abnormal wear, vibration and noise between gears and bearings, and greatly extends the service life of the entire gearbox assembly.
We select high-strength cast alloy as the raw material, with strict heat treatment and surface anti-rust treatment. The finished product features excellent compression resistance, vibration resistance, high-temperature resistance and corrosion resistance, adapting to harsh working scenarios such as mountain roads, construction sites and long-distance highway freight. Each piece undergoes dimensional inspection, sealing test and assembly fit test before delivery to guarantee high interchangeability with the original gearbox, ensuring no installation deviation and stable long-term sealing performance after replacement.

 

 Material Composition 

 

  • Base material: High toughness nodular cast iron, the mainstream raw material for heavy-duty transmission structural parts
  • Surface treatment: Blue zinc electroplating for rust and oxidation resistance
  • Processing craft: Full CNC turning, precision drilling and groove milling to ensure flatness and size tolerance of the fitting surface

 

Primary Applications

 

  • Compatible with ZQC2000 series heavy truck transmissions, mainly matched to Sinotruk HOWO, Shacman and other domestic heavy commercial vehicles
  • Applicable vehicle types: Tractor heads, tipper trucks, engineering heavy trucks and long-distance freight heavy trucks
  • Market orientation: Aftermarket replacement spare parts, bulk export to Russia, Central Asia, Pakistan, Kenya and other overseas regions for repair shop and fleet maintenance use

 

 

Key Advantages

 

  • OEM-level dimensional accuracy, completely interchangeable with original factory parts without modification during installation
  • Strong shock resistance and load capacity; nodular cast iron body resists long-term vibration and high torque deformation
  • Reliable sealing performance, perfectly matched with standard oil seals to eliminate oil seepage and dripping faults
  • Durable anti-rust plating layer, adapts to harsh working environments such as dust, mud and high temperature
  • Factory direct supply with stable inventory, favorable wholesale bulk prices compared to genuine OEM components
  • Standardized packaging suitable for FCL sea freight, supporting large-volume export orders
