4. Installation & Operation Manual

4.1 Pre-installation Inspection

1. Confirm the part number is exactly 5A28137G04, check outer packaging integrity; inspect workpiece surface for bumps and scratches, verify threads and positioning interfaces are free of deformation.

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

4.2 Installation Steps

1. Dismount the aged and damaged original component of the identical part number, completely clear residual gaskets and debris inside the mounting seat.

2. Align 5A28137G04 with positioning bayonets and insert smoothly, then implement temporary manual pre-fixation.

3. Tighten fasteners step by step in accordance with OEM specified torque values. One-time forced tightening is forbidden to avoid stress deformation of the component.

4. Manually rotate the matched transmission assembly after installation, check for jamming, displacement or abnormal operating noise.

4.3 Trial Operation & Routine Maintenance

1. Perform a 10–15 minute no-load trial run; full-load operation can only be started after confirming no leakage, overheating, vibration or other abnormalities are detected.

2. Inspect and re-tighten connecting fasteners every 3000 cumulative working hours, replenish lubricating grease timely.

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

4.4 Important Precautions

1. This component is only compatible with designated matched equipment; forced cross-model refitting is not allowed.

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

3. Store the product in a dry and ventilated warehouse, keep isolated from acids, alkalis and corrosive substances, avoid direct sunlight and humid storage environments.
