Pfaff 335-17Bl

[Uwe]

Also check out the Kwok Hing page for the Pfaff 335 for a nice overview of what's available for the Pfaff 335. The regular needle plate and feed dog set come in three sizes - regular, medium and small. The maximum stitch length you can use decreases as the opening in the needle plate gets smaller. Almost any of the presser feet on that page should work for you.

The "normal" non-binder setup would include the 91-158 206-034 needle plate and 91-059 229-04 feed dog set:

and the KP335W presser feet:

For the arm cover plate, you may be able to just remove the guide fingers and threaded bits that are attached now to make it flat with nothing sticking up.

The Kwok Hing parts are available from various resellers, or directly from the manufacturer if you get their attention.

The first thing I noticed was that the needle was in backwards. (always in troubleshooting mode).

Good find, and deal!

This is all quite interesting to me because of a recent acquisition- a Mitsubishi CU-865-22.... Which looks for all the world like someone grafted a later model Singer 211U156* to to the lower portion of a Pfaff 335, which sort of ties in to the two machines mentioned in the original post.

My machine doesn't seem to have a whole lot of info circulating in the wild, so it makes me wonder how much stuff from these other machines it resembles will interchange.

Great stuff, fellas, lots of good info here.

Sark9, that (lower) cylinder arm definitely appears to be identical to mine, right down to the shape of the cover plate and various screw holes. Your machine looks to be in excellent condition, btw.

Eric, that's because I took the needle out to check the size and obviously put it in backwards (just to see if anyone is paying attention....).

Jimi, you're right, the tension screw is missing (hadn't got that far to realize it!), but I should be able to find something suitable from my spares. Thanks for the great photos. The feed dog doesn't look as though it ever had teeth, if someone ground them off they did an awfully neat job on it! I found the serial no. this morning - 4994398. How does this relate to yours?

Uwe/jimi, that Kwok Hing site looks like where I need to go.

Photo of the needle bar. Does that help?

Hi dikman , yes your machine is 3 years newer, here is a pdf of the parts for the old class machines, dont know if you have this already?? you can look up the nº of your feed dog to see if it is the same as the one here. if it was not ground off then it should not have the long opening to the left on the needle plate (i think), that would be where the row of teeth move backwards and forwards??335 H3 Subclass Old C.pdf. yes thanks for the pic of the needle bar. what is the diameter of your needle bar? the presser foot tension screw is not metric, so you might have to scrummage around a bit to find one?

I stand corrected! Pfaff 335 is a needle feed machine after all.

Apparently I never looked ad the needle movement from 90 degree angle yet!

Looking for a "slap on the head" smilie... Here!

Thanks for that list, jimi, it's been added to the growing collection of paperwork for this machine. I can't measure the needle bar yet, as both of my digital calipers have a flat battery!!!

The part numbers on mine are - feed dog 46497B (no Pfaff marking), inner foot Pfaff 5.0B, 4C629 and outer foot Pfaff 8.0 A/B, 40432. I've attached a photo of the feed dog, and looking at it under strong magnification it may have been ground down, although why they would go so far down if they only wanted to remove the teeth I don't know.

The part no. on the feed dog may mean it's a non-genuine part? The other part no's, while Pfaff, don't appear to line up with their current numbering system.

I'm thinking that I might drop into the sewing machine place in town sometime, as he mentioned sourcing generic feet, and see what he can come up with (looks like I'll need the inner/outer feet, feed dog and needle plate). I'll make up a new cover plate for the arm, as the two threaded pins on the existing one have been brazed on, so I'll leave that intact.

I tried it out today, with a small (45mm) pulley on the motor, but it's still too difficult to control for my needs. I'll either have to make a pulley reduction thingy, or buy another servo motor. Part of the problem, I think, is the pulley on the handwheel is too small but it won't be easy to fit a bigger one.

There are several makes and models of servo motors available for under $130/150. They cost about the same as a speed reducer pulley set or a variable frequency drive.....I've only had two clutch motors that were really controllable, and they were still not as friendly as a decent servo. I personally find even the quietest clutch motor's humming a bit... annoying.

My last servo cost $250 ($205 without the needle sync) and that was pretty much the best value that I could find (out of China). My pulley reducer cost $0, because I used what I already had. I suspect that I'll end up buying another servo, however, as experience has shown me that even with a pulley reducer clutch motors can be a pain.
