VIKING THREAD TENSION UNIT # 68006054

SKU & PART # 68006054



Upper Thread tension unit.

For the Husqvarna Viking Brilliance 80Q and Designer Sapphire 85Q

This is the upper tension side of the Viking Thread Portioning System Aassembly and is sold separately from the Thread Portioning Roller Shield Unit (P # 68006046). However, they should be replaced together, as one defect will usually cause both sides to fail. The most common failier is thread wrapped into the roller portioning gears, which causes that side to bind, then fail and in turn, stress the tension side, causing it to fail.
