Hello Pat,
If I remember the Jones 741 came with the tension unit facing you in which case the large spring goes in first , then there should be a plate, then a curved disc, then flat disc, then curved disc then cone disc, then cone spring, then white nylon adjuster then cover, if you have the Brother 741 the tension unit will be at the top on the left hand side.
