4. User Manual

4.1 Pre-installation Inspection

1. Confirm the component model is 5A26391G04. Check the outer package is intact and undamaged; ensure no dents or scratches exist on the workpiece, and threads and positioning interfaces are free of deformation.

2. Remove oil stains, iron filings and impurities on the equipment mounting base to create a flat and clean assembly contact surface.

4.2 Installation Steps

1. Dismount the aged and damaged old component of the identical model, and thoroughly clear residual gaskets and debris inside the mounting seat.

2. Align Model 5A26391G04 with positioning bayonets and insert smoothly, then fix temporarily through manual pre-positioning.

3. Tighten fasteners step by step according to the torque specified by OEM. Violent one-time tightening is forbidden to prevent stress deformation of the component.

4. Manually rotate the transmission assembly after installation, and verify no jamming, displacement or abnormal noise appears.

4.3 Trial Operation & Routine Maintenance

1. Run a 10–15 minute no-load trial operation. Full-load operation can only be launched if no leakage, overheating, vibration or other abnormalities are detected.

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

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

4.4 Precautions

1. This component only fits designated matched equipment; forced cross-model refitting is not permitted.

2. Installation operations must be completed by certified professional maintenance technicians.

3. Store the product in a dry and ventilated warehouse, keep away from acid, alkali and corrosive substances, and avoid direct sunlight and damp surroundings.
