138300200 Take-Up Lever for Jack Sewing Machine

The 138300200 Take-Up Lever is a genuine Jack part for single-needle lockstitch sewing machines. It moves up and down in sync with the needle bar to feed and pull back the correct length of top thread on every stitch cycle. Best for tailoring units and garment factories running Jack lockstitch machines where thread loops, skips or uneven tension point to a worn take-up lever.

How To Replace This Take-Up Lever

1. First, switch off the machine and remove the face plate covering the take-up mechanism.
2. Next, unthread the machine fully so no thread remains routed through the lever.
3. Then, remove the retaining screw or link pin holding the old lever in place.
4. After that, fit the replacement 138300200 lever and reconnect the link pin.
5. Following this, check the lever moves smoothly through its full stroke without binding.
6. Finally, re-thread the machine, refit the face plate and test-stitch a sample piece before full production.

Frequently Asked Questions

What symptoms point to a worn take-up lever?

Loose loops of thread on the underside of the fabric, skipped stitches at speed, or thread breaking near the take-up point are the common signs. These symptoms also overlap with tension and timing issues, so it’s worth confirming the lever itself is worn or loose before ordering.

Do I need a technician to fit this part?

Fitting the take-up lever means removing the face plate and working near the timing linkage, so it’s best handled by someone familiar with the machine’s internals. An incorrectly seated lever can throw off stitch timing rather than fix it.

Will this fit any Jack lockstitch machine?

Jack uses this lever across several single-needle lockstitch models, but lever length and pivot spacing can vary between generations. Compare your existing lever’s dimensions against 138300200 before ordering if you’re not certain of your exact model.

Is the take-up lever the same as the thread tension assembly?

No — the tension assembly controls how much resistance the thread feels, while the take-up lever controls the timing and amount of thread pulled through per stitch. Both affect stitch quality but are separate, independently replaceable parts.

Does this ship with COD and pan-India delivery?

Yes, this part ships pan-India with cash-on-delivery available on eligible orders, along with GST billing for business buyers.
