Replace needle replace broken needle

Yes you can substitute the appropriate needle and glue them in place as long as the needle plate is not cracked.and broken. Be abundantly sure ithe needle plate is not broken

do you need to find a place to get more needles?

You need to tell us make and model when you post a question for us to give you a really good answer.

Here the generic way to replace a needle:

1. Raise the needle fully.
2. Look for a thumb-screw right where the needle joins the needle mechanism.
3. Loosen the thumb-screw and catch the broken needle when it falls out.
4. Put a new needle in the place occupied by the broken needle. Be sure the flat side of the needle is away from you.
5. Tighten the thumb-screw.

I don't know of a way to repair the needle clamp. It will more than likely have to be replaced. The local authorized husqvarna viking dealer should be able to service the machine. You can find the nearest dealer from husqvarna viking website - http://www.husqvarnaviking.com/us

there should be a little hand screw near the top of the needle, loosen it enough to slide the broken needle out, replace with a new needle and tighten, Just remember, if you don't have the needle in properly you will ave issues. Usually, the flat part of the needle goes to the right, I have a brother sewing machine and the flat part on mune goes to the back though. Just take note when you remove the old needle as to the position. Also, a little known fact, a sewing machine needle should be replaced after 8 hours of use.

I use a small screw driver to undo the screw, insert the needle all the way into the needle holder--flat side to the back of the machine, then tighten the screw back

It sounds to me like you have replaced the broken needle with one that is too long (wrong size).Check your manual for the proper needle size and look through your collection, or head down to the local sewing shop and pick up a new pack of proper sized needles. Now if the needle you replaced the broken one with is the same size, you most likely didn't loosen the set screw up enough and therefore didn't slide the needle up far enough before locking it in. Double check this.

Good Luck!

The broken pins are called chaining pins and are tricky for the home user to replace without risking damage to the needle plate as they are difficult to remove and the tiny burr used to hold them firm can easily open up and no longer grip the pin.
There are only a couple of things under the needleplate that are likely to collide with the needles. 1. Lower looper - with the needles 2. Both Loopers colliding with each other - not with the needles 3. Needle guards attached to lower looper - with the needles 4. Fixed Needle guard - with the needles
If you remove the needleplate and VERY gently turn the handwheel you should be able to see and feel where the collision is occuring and have a better idea of the issue.
I would strongly advise that you do not try to operate the machine until you are sure that the colliding components are adjusted. Broken loopers are approx $65 AUD and guards, tho' only about $20 AUD require some finesse in adjustment. Chain Pins approx $6 AUD
My recommendation is to speak with your local Janome dealer for advice and an approximate price to repair, replace or adjust as the case may be.
Your country's Janome website is certain to have a Dealer Locator page to list the nearest to you.
This is one occasion where it is sensible to call on the people who do these things routinely rather than try to DIY and make a more expensive hash of it.

look for the nut into the handle of needle, it is an rough nut then loosen it and pull the needle inside
