4. User Manual

4.1 Pre-installation Inspection

Confirm the part model is 5A26391H03. Inspect the outer package for integrity; check the workpiece surface is free of dents and scratches, and threads and positioning interfaces have no deformation.
Remove oil stains, iron filings and foreign contaminants on the equipment mounting base to create a flat, clean mating surface.

4.2 Installation Steps

Remove the aged and damaged original part of the same model, and fully clear leftover gaskets and debris inside the mounting base.
Align 5A26391H03 with positioning catches and insert smoothly, then fix temporarily by manual pre-positioning.
Tighten fasteners step by step following the torque standard specified by OEM. One-off violent tightening is prohibited to prevent stress-induced deformation of the component.
Manually rotate transmission assemblies after installation, and verify no jamming, shifting or abnormal running noise occurs.

4.3 Trial Operation & Regular Maintenance

Perform a 10–15 minute no-load trial run. Full-load operation can only be activated after confirming no leakage, excessive temperature rise, vibration or other malfunctions.
Inspect and re-tighten connecting components every 3000 cumulative working hours, and replenish lubricating grease in a timely manner.
Long-term overload operation or operation exceeding the allowable temperature limit is strictly forbidden.

4.4 Precautions

This component is exclusively matched to designated specific equipment; forced refitting across different models is not permitted.
Installation work shall only be carried out by certified professional maintenance technicians.
Store the product in a dry and ventilated warehouse, isolated from acid, alkali and corrosive substances, and avoid direct sunlight and humid storage environment.
