Why would you want to take apart the tension assembly unit on your vintage Empisal sewing machine? Good question. Perhaps like me, the tension check spring broke and needed to be replaced. Maybe your unit needs to cleaned. Whatever your reason, I wouldn't advise doing this unless it's absolutely necessary.
Should you decide to take your tension unit apart make a photo record of the process, your machine maybe not be identical to mine.
Finally, I'm no expert, I'm just sharing this in case it helps someone out there because when I broke my tension check spring I couldn't find any info online about what to do for this brand of sewing machine, and I had to figure things out for myself.
In the another post I will show you how to put the tension unit back together - which is a lot more complicated, so be warned!
