This nut can be quite tight due to corrosion. Use the pliers to gently loosen the retaining nut. Be careful not to damage the nut's threads or the handwheel shaft.
Once the nut is loose, unscrew it completely. The handwheel should now slide off the shaft. If it's stuck, apply a small amount of lubricant and gently work it free. Avoid forcing it.
2. Inspection Before Replacement
Before installing the new handwheel, take a moment to inspect the handwheel shaft. Look for any signs of damage, corrosion, or wear. If the shaft is damaged, it may need to be repaired or replaced – a shaft replacement would likely require professional assistance. Sometimes, these vintage machines present challenges beyond simple repairs, requiring a deeper understanding of their intricate mechanisms. For a more challenging task, consider how the motor itself functions and how you could ensure its optimal performance - learn more about understanding the Singer Featherweight motor, repair, and maintenance.
Clean the shaft thoroughly with a clean rag and apply a light coat of sewing machine oil. This will ensure smooth rotation and prevent future corrosion.
3. Installing the New Handwheel
Slide the new handwheel onto the shaft, ensuring it's properly aligned. Secure the handwheel by tightening the retaining nut. Again, avoid overtightening, as this can damage the threads.
Use the pliers to ensure the nut is snug, but not overly tightened. A properly secured handwheel will rotate freely and smoothly.
4. Post-Replacement Checks
After replacing the handwheel, it's crucial to test its functionality. Rotate the handwheel manually to ensure it moves freely and doesn't bind. Check for any unusual noises. Run a test stitch to verify the needle movement and stitch length are correct. If you encounter any problems, double-check the handwheel's alignment and nut tightness.
5. Lubrication & Maintenance
Regular lubrication is key to maintaining your Singer 12. Apply a small amount of sewing machine oil to the handwheel shaft after each use. This will prevent corrosion and ensure smooth operation. Wipe away any excess oil to prevent fabric staining.
