How to tell
Inconsistent bobbin thread tension, skipped stitches, loose bottom thread, or birdnesting on the underside of the fabric. The spring may appear visibly stretched, bent, or corroded.
Fix
- Inspect the bobbin tension spring for any signs of deformation, corrosion, or loss of spring tension. It should provide consistent resistance when thread is pulled through the bobbin case.
- Remove the bobbin case from the machine.
- Carefully unhook the old tension spring from its mounting post on the bobbin case.
- Install the new 32mm Bobbin Tension Spring 0767-150590, ensuring it is seated correctly and provides proper tension.
- Test the bobbin tension using a bobbin tension gauge or by pulling thread through the bobbin case to feel for consistent resistance.
A worn bobbin tension spring is a common cause of lower thread issues and should be replaced promptly to maintain stitch quality.

Maintenance schedule
| When | What to do | Why |
|---|---|---|
| Daily (before/after each shift) | Clean the bobbin case and rotary hook area. | Removes lint and thread debris that can cause tension issues, skipped stitches, and wear. |
| Daily (before/after each shift) | Oil all designated lubrication points. | Ensures smooth operation of moving parts, reduces friction, and prevents premature wear. Refer to your machine manual for specific points. |
| Daily (before/after each shift) | Wipe down the machine exterior. | Prevents dust and debris from accumulating and potentially entering internal mechanisms. |
| Weekly | Clean under the needle plate and around feed dogs. | Removes compacted lint that can impede fabric feeding and stitch formation. |
| Weekly | Inspect presser feet for wear or damage. | Worn feet can cause uneven feeding and poor stitch quality. Replace as needed. |
| Weekly | Check thread tension components (tension discs, springs). | Ensures consistent stitch quality and identifies worn parts like bobbin tension springs early. |
| Monthly or Every 200-250 Hours (whichever comes first) | Clean the entire machine head, including thread guides and take-up lever area. | Removes hidden lint and debris that can affect thread flow and machine performance. |
| Monthly or Every 200-250 Hours (whichever comes first) | Inspect drive belts for tension and wear. | Loose or worn belts can affect timing and motor performance. Adjust or replace if necessary. |
| Monthly or Every 200-250 Hours (whichever comes first) | Check for loose screws and tighten as needed. | Vibration can loosen fasteners, leading to misalignment or component damage. |
| Every 6 Months or Every 1000 Hours (whichever comes first) | Inspect the rotary hook for nicks, burrs, or excessive wear. | A damaged hook can cause thread breaks and skipped stitches. Replace if damaged. |
| Every 6 Months or Every 1000 Hours (whichever comes first) | Inspect needle bar and presser bar for excessive play. | Excessive play can indicate worn bushings or bearings, affecting stitch accuracy. |
