I found an old Husqvarna Viking 6370 sewing machine from tori.fi online second hand shop. The seller told me that she has sewn with the machine a short while ago and that it works just fine. Well. I do not doubt the the machine sews – but how well it sews is a totally different story. Check these things to avoid the biggest problems.
Stitch selection knob was totally jammed to blue position, reverse button was stuck, stitch length selector was stiff to turn and buttonhole mechanism could not be activated as the knob was stuck and could not be lifted up.
Those are very common problems with older Husqvarna Viking sewing machines. Blowdryer and teflon based spray lubricant worked perfectly again. However it took a whole day to release the stiffness. I sprayed the oil to one jam at a time and held small piece of fabric using tweezers so the oil did not spread all over the machine. Then I heated the spot using blowdryer and carefully turned the knob back and forth. When the jam slowly opened I added some oil and wiped dirty extra oil away with the cloth. I repeated the oil-blowdrier-turning-wiping procedure around 8–10 times before the stiffness was gone.
The biggest issues are related to the plastic parts inside
The most problematic issues of Husqvarna Viking 6000 series sewing machines are related to internal cam stack and take up slide as they are made out of plastic. Repairing tha machine is way more difficult and expensive if there are any cracks on them. It can also be difficult to find the spare parts. I was lucky – those parts were just fine in this machine.

On the video I show how to inspect the condition of the parts and operation of functions of Husqvarna Viking 6370 sewing machine.
There were lots of other issues as well
This Husqvarna Viking 6370 sewing machine needed also shuttle timing, feed timing, sandpaper treatment for the needle plate and adjustments for thread feeding spring and top thread tension. I am really getting familiar with the Technical Briefing.
Accessories are difficult to find
There was only one cam included. I ordered one from eBay and got the third one from a member of “Ompeluelämää” Facebook group. She also sent me the extension table. I have been bying feet from here and there. One set of feet that I bought from Tradera.com is on it’s way from Sweden.
For a good cause
I have enough sewing machines for my personal needs and there is no more room in my house for an extra machine. I really enjoyed the repair project and I learned a lot. I will donate this machine for a young asylum seekers / refugees.
