I have a Necchi 537-L and I would like to know the year of it. Any other information that I could get about this sewing machine would be great to thank you for your help in advance

Question edited for clarity and all the typos.
Question moved from Televisions to make model category.

The whirling noise is the motor. It may be that the drive belt has broken?

When was the last time it was professionally cleaned, serviced and timed? With moderate use, they need doing every 2 to 3 years. The inside workings of sewing machines are very tough and seldom 'break'.

You can purchase a copy of the Necchi 537L manual as either a PDF download or a printed manual here: https://www.sewingpartsonline.com/instruction-manual-necchi-537-l.aspx? . There are several online guides for threading Necchi machines. These may help. However I don't know how different the leather and lace 537 is from other Necchi machines. The manual will have the threading diagrams.

I hope this helps .

It is generally the large knob on the right side about halfway between the top and bottom of the machine. The numbers should range from zero to 4 or 5. Zero is zero stitch length, five would be the largest stitch length.

NECCHI Model 537 Sewing Maching INSTRUCTION MANUAL

You can purchase a copy of your manual here: Necchi 537 Instruction Manual

necchi's are good sewing machines, I personally own 2 necchi's,
and I've never had any problems with them and I've had them for around 10 years, here is what I suggest
use a new needle--one that is for the fabric your sewing
rethread the machine top and bobbin--use every thread guide
try a different bobbin
clean under the needle plate and in the bobbin area for lint
call a sewing machine repair shop in your area and ask them how
much a necchi sewing machine is worth or check on ebay and see
what they are selling for.
since you inherited the sewing machine,, having the machine
serviced completely would be a good idea, that way they can check
to see if the grease and oil that the gears and parts use is fresh or
needs to be replaced and it's very important the grease and oil are in
good condition.
and they can make sure the machine's is timed correctly
ask how much a tune up cost for a sewing machine and then
you'll have to decide if the price is what you want to pay.

also since the sewing machine is doing repeat loops from the bobbin
adjust the top thread tension just a little at a time till the stitch looks
normal on a scrap piece of fabric
if you don't have a manual on the sewing machine let me know & I'll try
to find you one.
I've been sewing for 30 years, and like I said I have 2 necchi's already
and I had one other one before these 2 that I have now and it lasted me
for around 15 years and I wore it out making clothes.
I wouldn't hesitate to buy or except another necchi because I know
they are good machines.
I have a mechanical and a electronic necchi and my husband uses the
electronic one when he makes quilts.
good luck on your decision
Merry Christmas and A Happy New Year

Hi! You've got a great machine there! The folks that have them think those older Italian-made sewing machines are the best ever made. Here are a couple of places to look at for your belt: http://www.sewingpartsonline.com/necchi-sewing-machine-parts-model-list.aspx

If you need a manual, try http://www.sewingstyle.com/Necchi-Sewing-Manuals.html
There's a Yahoo users group dedicated to the Italian made Necchis--they have a lot of good information about how to care for your new baby so you might take a look.
Let me know if this helps, ok?
Happy Sewing!

I could not think of another way then free-motion sewing.
Drop the feed dogs, and put a spring loaded needle on.

The proper tension for the 537 is between 4-6. You need to make sure that your presser foot is in the up position before threading.
