57Leather Report post Posted July 20, 2015 Brand new Pfaff cylinder machine and cannot use a heavier thread because the feed dog opening is so small. At least the one that came with the machine is so small--you put a 24 needle and a 277 thread and it just jams up.. Does anyone know if pfaff offers this larger hole in a feed plate??? Really stuck--about ready to take a drill to it and enlarge the hole myself--last option of course. Also in need of a supplier for Pfaff parts in general. Thanks any help is greatly appreciated.

Uwe Report post Posted July 20, 2015 (edited) The Pfaff 335 was not designed to work with needles and thread as thick as you want to use. Even the heavier of the two Pfaff 335 versions only goes up to 120Nm needles, which is a size 19 needle and the most the machines will happily handle is perhaps 138 thread. I think neither you nor your machine will be happy with size 24 needles and 277 thread. That's 441 or 205 class territory. I have a Pfaff 335 and an Adler 205-370. The 205 picks up where the 335 leaves off, there's pretty much no overlap in their design specs. The 205 will not be happy doing fine threads, and the 335 will not be happy doing heavy threads. I'm attaching the relevant snippet from the 335 manual. Edited July 20, 2015 by Uwe Quote Share this post Link to post Share on other sites
DrmCa Report post Posted July 20, 2015 Yeah, what Uwe said - I learned that the same way a few weeks ago right in this forum. Mine is 335-17 and the largest needled is stitches with is #22. Quote Share this post Link to post Share on other sites
shoepatcher Report post Posted July 21, 2015 57Leather, You can run up to a #24 needle in a Pfaff 335 class C or D. It may mean enlarging the hole in the throat plate and or resetting the hook and needle guard in relation to the needle. I have run and do run #23 and 24 needle in the Pfaff 335 machines we have at work and on mine at home. I have never run #207 in the machine. #277 thread is harness weight thread and should never be run in this class of machine. glenn Quote Share this post Link to post Share on other sites
Art Report post Posted July 21, 2015 Pfaff is German. They build sewing machines much like they build cars. Industrial Pfaff machines are the race cars of the sewing machine world. Vie build it to do von ting und to do it werry vell, danke. Vertical shaft bobbins (horizontal or drop in bobbins) are not made for a wide variety of thread. The Pfaff 335 seems to like 92 or 138 and not much else, in fact I have found they like a #19 needle and 92 thread best although a #21 or #22 and 138 works too. I'm sure I could set one up to run 207 or 69 thread, but seldom both without adjustment. I am pretty sure 277 and that hook ain't a gonna work though, and you think they might just be telling you something with the size of the hole in the needle plate.

Trox Report post Posted July 22, 2015 If you need some aftermarket Pfaff parts (less expensive) to modify you can buy them here http://www.kwokhing.com/pfaff/ Original Pfaff parts are expensive and too expensive to do experiments on. Tor Quote Share this post Link to post Share on other sites
