4. User Manual

4.1 Pre-installation Inspection

1. Verify the component model is 5A26371H12, check the outer package is intact and undamaged; confirm there are no dents or scratches on the workpiece, and the threads and positioning assembly interfaces remain undeformed.

2. Clear oil stains, iron filings and foreign matter on the equipment mounting base to form a flat and clean mating surface for assembly.

4.2 Installation Steps

1. Dismount the aged and damaged old part of the identical model, and completely remove residual gaskets and debris inside the mounting base.

2. Align Model 5A26371H12 with positioning bayonets and insert smoothly, then perform temporary fixing through manual pre-positioning.

3. Tighten fasteners step by step in accordance with the torque value specified by the original equipment manufacturer. One-off forced tightening is forbidden to avoid stress deformation of the component.

4. Manually rotate the transmission assembly after installation, and check for jamming, displacement, abnormal noise and other abnormal conditions.

4.3 Trial Operation & Routine Maintenance

1. Conduct a 10–15 minute no-load trial run. Full-load production can only be initiated if no leakage, excessive temperature rise, vibration or other abnormalities are detected.

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

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

4.4 Precautions

1. This component is only compatible with 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 environment.
