Anti-Leak Axle Intermediate Box Protective Cover DZ90129320115 Red Primer Coated Cast Cover For Heavy Haul Truck Drive Axle Overhaul

Product Description

This transfer case cover, OEM number DZ90129320115, also marked casting code HD4692502025, serves as the sealed outer protective shell for the heavy truck drive axle intermediate transfer assembly. It fastens onto the transfer box housing via a full perimeter of evenly spaced bolt holes, fully enclosing internal drive gears, bearings and lubrication oil. Precision machined sealing grooves and stepped bore openings match axle input/output shafts perfectly to stop gear oil leakage and block dust, mud and water from invading the gear chamber. The red anti-rust primer finish shields the casting from corrosion under harsh chassis operating conditions, and all mounting bores follow factory OEM specs for direct bolt-on replacement without grinding or re-drilling during axle repairs.

Key Product Advantages

• High-strength ductile cast iron one-piece casting with stress relief annealing, excellent impact resistance to withstand heavy load axle torque and road shock without cracking
• Continuous precision machined flange sealing surface, flatness strictly controlled to fit gaskets tightly and eliminate persistent gear oil seepage issues
• Dual stepped machined bore seats for shaft and sensor installation, smooth inner finish to prevent shaft seal wear and extend oil seal service life
• Uniform red rust-proof primer coating across all casting surfaces, resisting oxidation, mud and road salt erosion on the vehicle undercarriage
• Full circle standardized bolt hole layout, evenly distributed load force to avoid cover deformation and loose sealing after long-term operation
