4. User Manual

4.1 Pre-installation Inspection

1. Verify the part model is 5A26391G05. Check the outer package is intact; confirm no dents, scratches or deformed threads and positioning interfaces on the workpiece.

2. Clear oil stains, metal scraps and contaminants on the equipment mounting base to obtain a flat and clean fitting surface.

4.2 Installation Procedures

1. Dismount the aged and damaged original part of the same model, and thoroughly remove residual gaskets and debris inside the mounting base.

2. Align 5A26391G05 with positioning bayonets and insert smoothly, then fix temporarily by manual pre-positioning.

3. Tighten fasteners step by step following OEM specified torque. One-time violent tightening is forbidden to prevent stress deformation of the component.

4. Manually rotate transmission assemblies after installation and check for jamming, offset or abnormal operating noise.

4.3 Trial Operation & Daily Maintenance

1. Perform a 10–15 minute no-load trial run. Full-load operation can only be enabled if no leakage, excessive temperature rise, vibration or other faults are detected.

2. Inspect and retighten connecting components every 3000 cumulative working hours, and replenish lubricating grease in a timely manner.

3. Long-term overload operation or operation exceeding the temperature limit is strictly prohibited.

4.4 Safety Precautions

1. This component exclusively matches designated supporting equipment; forced cross-model refitting is forbidden.

2. Installation shall only be carried out by certified professional maintenance technicians.

3. Store the product in a dry and ventilated warehouse, isolate it from acid, alkali and corrosive substances, and avoid direct sunlight and humid storage conditions.
