A detailed Gearbox WEEKLY preventive maintenance Inspection checklist
1. Visual Inspection
2. Lubrication Check
3. Gear Alignment
- Use a straightedge or laser alignment tool.

- Rotate the shaft to measure deviations.
- Document the readings accurately.
- Loosen the mounting bolts slightly.
- Use shims or adjustment screws to align.
- Re-tighten the bolts evenly.
- Recheck alignment after adjustments.

- Check for burrs or debris.
- Use a straightedge to verify flatness.
- Address any irregularities before proceeding.
- Refer to the manufacturer's torque specifications.
- Use a calibrated torque wrench.
- Tighten bolts in a crisscross pattern.
- Double-check torque values for accuracy.
- Inspect tools for any visible damage.
- Replace worn or damaged tools promptly.
- Ensure fixtures are calibrated and functional.
- Maintain a log of tool conditions.
- Check for cracks, wear, or distortion.
- Ensure coupling halves are aligned.
- Verify that coupling is securely fastened.
- Replace damaged couplings as necessary.
- Create a log sheet for measurements.
- Include date, time, and technician name.
- Record both pre- and post-adjustment readings.
- Store records in a maintenance database.
- Run the equipment for a short duration.
- Measure alignment again using the dial indicator.
- Compare new readings with previous logs.
- Make further adjustments if necessary.
- Establish a maintenance schedule.
- Record operational hours for tracking.
- Set reminders for alignment checks.
- Review alignment status periodically.
4. Bearing Inspection
- Examine bearing surfaces for pitting, scoring, or discoloration.
- Check for any play or excessive movement in the bearings.
- Look for any signs of overheating or unusual wear patterns.
- Use a stethoscope to isolate sounds from the bearings.
- Identify any grinding, clicking, or rumbling noises.
- Note any changes in sound compared to previous operations.
- Use an infrared thermometer to measure surface temperatures.
- Compare temperature readings to manufacturer specifications.
- Investigate any readings above normal operating range.
- Check seals for cracks, tears, or degradation.
- Ensure seals are seated correctly without gaps.
- Verify that no lubricant is leaking from the seals.
- Measure clearance between the bearing and housing.
- Use appropriate tools to ensure accurate measurements.
- Ensure clearance is within manufacturer's specified tolerances.
- Utilize a vibration meter to assess vibration amplitude.
- Record frequency data to identify specific issues.
- Compare readings to baseline measurements from previous inspections.
- Inspect for rust or discoloration on bearing surfaces.
- Look for foreign debris or particles that could affect performance.
- Clean surfaces if contamination is detected.
- Check lubricant levels and top up if necessary.
- Inspect lubricant for signs of contamination or degradation.
- Ensure the lubricant type matches operational requirements.
- Look for cracks, deformation, or corrosion in the housing.
- Check mounting surfaces for flatness and integrity.
- Ensure no debris is present that may affect bearings.
- Record all inspection results in a maintenance log.
- Include measurements, observations, and any anomalies.
- Ensure documentation is clear and accessible for future reference.
- Review past inspection logs for consistency.
- Identify any deteriorating trends in bearing condition.
- Highlight any recurring issues that need addressing.
- Use alignment tools to assess bearing positioning.
- Ensure bearings are properly seated within the housing.
- Adjust as necessary to correct any misalignment.
- Inspect retention methods for wear or damage.
- Ensure all components are securely fastened.
- Replace any worn or damaged retention devices.
