IslandMoose Report post Posted August 1, 2021 Good day, I've picked up a Pfaff 145 for a song, its a 145-6/1B H2S. There are a couple of issues with it that I want to address, aside from fitting a servo motor and restoring the table. 1. The bobbin lever comes into contact with the top of the hook assembly, the lever rides over the edge of the hook assembly, but there is considerable contact between the two and the machine binds at that point. With the hook assembly removed the machine rotates effortlessly. I believe the lever is damaged, so I've got a replacement coming. In the photo note I've removed the needle plate, but the lever strikes the hook assembly when everything is in it's proper place. 2. The stitch length lever does not move upward when the knob is rotated. It is constantly set at the longest stitch length at the bottom of it's travel. The lever will go up into reverse, but I cannot select a stitch length. Quote Share this post Link to post Share on other sites
trash treasure Report post Posted August 2, 2021 That square tab is supposed to fit in the notch on the underside of the needle plate - That's what keeps the bobbin case from rotating with the hook. Do that when you put the needle plate in, and problem solved. Quote Share this post Link to post Share on other sites
IslandMoose Report post Posted August 3, 2021 Thank you, but when the needle plate is in and the notch is properly held steady, the hook still revolves around and the top of the hook assembly contacts the underside of the case lever arm (see photo of part I am referring to). It's as though the case lever isn't sitting flush on the lower casting, but it is. Quote Share this post Link to post Share on other sites
trash treasure Report post Posted August 3, 2021 Sorry - I misunderstood the issue. Maybe it's just that the lever is bent / damaged - Does it meet the stop tab on the bobbin case squarely, when it comes around? It should be exactly level with that angled tab.

Ive ordered a replacement, it is not level with the stop tab on the bobbin case, it tries to go under it...explains why it contact the hook. Thank you.

trash treasure Report post Posted August 4, 2021 Hey! Maybe I got it right ! As they say: Even a blind pig finds a nut, sometimes :~) Quote Share this post Link to post Share on other sites
IslandMoose Report post Posted September 12, 2021 Up and running! Fitted a 550w servo motor, a new bobbin winder, and restored the original table. I cleaned and lubricated the machine, including the grease enclosures, then I timed it as per the service manual. It's giving me some really good stitches in heavy Sunbrella fabric.
