I just finished getting my Pfaff 1471 serviced and darned if I didn't get some knit fabric jammed down into the needle hole and now it clicks when I sew (yes, it's a new needle). Is there any way I can adjust the timing myself without taking it back in to get serviced?? I'm pretty good with mechanical stuff like that, being that I have to repair equipment at work lots.

If it's still under warranty I woulldn't 'fix' it. I'd take it in to the repair person. (I would anyway..I'm handy too, but I don't mess with expensive things I might screw up). Chrys

"Timing" is not one adjustment, it's several adjustments that all must be correct before the machine will sew properly. Needlebar height, needle-to-hook clearance, hook timing, and feed timing all interrelate. Before you adjust anything, you need to figure out what is "clicking" and correct that problem. Is the hook hitting the needle? Is some fabric jammed between the feed dog and the throat plate? Is a piece of a broken needle lodged down in the hook area? I use a mechanic's stethoscope to find unusual noises, you can also hold the handle of a screwdriver to your ear and touch the tip of the screwdriver to different areas on the machine. You will hear the click getting louder as you get closer to the source. Ed |

Laura, on that model your problem probably lies in either the hook being out of time or the hook has play in it allowing it to move front to back. If it has jumped time it needs to be determined where the "jump" occured and why before retiming. If you recently had the machine serviced the Tech. will most likely realize that it could be his fault because something wasn't set quite right or tightened enough. I pesonally feel that if a quality machine jumps time for any reason in less than a year after I've serviced it it is my fault. You should not be able to make a good machine jump time if everything is set properly. About the only reason he might want to charge you would be if the timing belt is bad. Which is possible but unlikely. Even then he might feel that he should have caught the belt and therefore not charge you. This is not a fix it yourself job. The settings on European machines are much more precise than on the Japanese and Chinese machines. Gauges are a must to get them operating at their optimal. Have fun or don't do it, Tom

Tom, I've noticed that the bobbin case is loose, in that I can move it clockwise/counterclockwise about 1/8-1/4" and the needle coming down is just barely touching the edge of the bobbin case, causing the clicking. Is it normal to have 'play' in the bobbin case?

Is it normal to have 'play' in the bobbin case? The "play" you are asking about is necessary to allow the thread to pass between the bobbincase and hook. All machines have it. The needle should NEVER be able to touch the bobbincase, hook, or hook basket. If it is something is not set right. Have fun or don't do it, Tom

Well, I just finished giving my machine a really good cleaning, and found some thread wrapped around in behind the bobbin case, and lots of fluff, and now it runs like a charm. Talk about feeling a little ditzy! Thanks for the input though Tom, really appreciate it!
