Simple Installation Tip (Install Guide Note)
🔧 Installation Tip: Always replace constant gears in matched sets when rebuilding a transmission stage. Use proper alignment tools and ZF-recommended lubricants. Ensure synchronizer hub clearance and check gear backlash (recommended 0.08–0.15mm). Never hammer directly on the gear—use a press for safe installation. We recommend professional installation by certified technicians familiar with ZF gearbox systems.
