How To Replace This Gasket

1. First, switch off the machine and remove the side cover screws.
2. Next, lift away the side plate and peel off the old, hardened gasket.
3. Then, wipe the mating surface clean of old gasket material and residual oil.
4. After that, position the new 10122113 gasket so every screw hole lines up.
5. Following this, refit the side plate and tighten the screws evenly in sequence, not just one corner at a time.
6. Finally, run the machine briefly and check the seam for fresh seepage before returning it to production.

अक्सर पूछे जाने वाले सवाल

Why does the Jack F4 need a side plate gasket at all?

The F4 head carries an internal oil sump that lubricates the hook and shaft during high-speed stitching. The side plate gasket seals that housing; once it hardens or tears with age, oil weeps out at the seam and can stain garments and the work table.

How do I know it’s time to replace this gasket?

Visible oil residue around the side cover seam, a drop in the sump’s oil level faster than usual, or a stiff, cracked-looking old gasket when the cover is opened are the usual signs. Technicians typically replace it whenever the side cover is opened for any other repair, since it is inexpensive compared to a full reseal visit later.

Will this gasket also fit the Jack F5?

The F4 and F5 share a similar body but side-plate dimensions can differ slightly between production batches. Compare the old gasket’s outline against 10122113 before fitting, rather than assuming a direct swap.

Can I reuse the old gasket if it still looks intact?

A gasket that has been compressed once rarely reseals as well the second time, since the material loses its ability to spring back and fill small surface irregularities. For a lasting seal, technicians generally fit a fresh gasket any time the side cover comes off.

Does this come with COD and pan-India delivery?

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