How to replace tension spring on a Pfaff 145?

the spring you talking about is the take up spring,it goes against the body of the machine in such a way that when everything is put back together it must still be able to move freely as it control the tension on the take up lever.hope it helps

Thanks, Johan, for answering. The spring is on the main tension at the front of the machine. The spring itself is larger at one end, with a piece sticking out in front. My main question is if this part sticking out goes in front of the tension discs. It appears to in the manual and seems to make sense as it holds the thread going into the take up lever. Wish I knew how to put a picture on here.

please give more detail as where this tension spring is on your machine,there normally tension unit just left of needle bar and then one at bobbin case. the basic on tension unit is the take up spring against machine frame then follow the 2 discs with cups facing each other followed by the spring with big end against tension disc small washer with piece in middle followed by tension knob.hope all make sense
