Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 (edited) In this first picture you can see the bushings are in and lined up perfectly with the holes for oiling??? but it was not to be... A little oil and a soft face hammer, not a steel just in case. By the way that part was full of dirt on the inside up near the top, it has a small sleeve if i remember on the inside. there is a small hole on the side probably for air as it looks too small for oiling?? Forgot to say, when taking this part out there is a small grub screw on the side to loosen first! Now to get the spring in there for the back foot!! Edited December 29, 2018 by jimi Quote
Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 I am thinking i went OTT this time with the amount of pictures??? This spring is very strong!! and i always try to note down where the linkages go, this way it will mate with the same part it was previously worn with. the small one here for the needle bar assembly has pfaff written on the back and the part nº for example so that was my reference. In this picture you can see the screw has been taken out where the needle bar and foot assembly swing, If you do not want to take the whole shaft out then just take this screw out and slide the assembly off.

Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 So about this time i realized that something was put in wrong because when i could i would turn the hand wheel over to check now and again if everything was going ok, but there seemed to be something....mm giving resistance? so i checked the front assembly and that was ok and smooth, then i checked the small block and the bushing wheel that is for the foot lifter, but that had not been moved? (the one in the yellow circle in the box) and saw that the arm had moved after a cycle. so i looked back at the first picture, had a look at the old 335 and realized that the holes were slightly out of alignment for that reason, to not let the arms move. so bushings back out again and placed where they were slightly out of alignment before and that felt better after wheelin a couple of times. Here you can see the arm against the bushing, the back one the same. Quote
Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 (edited) So they seem to have went from a normal small coil spring next to the foot lifting lever to this? This is the parts on the back. (bushings were still not changed yet) Don´t forget this pin?And that small one. That´s where that small pin goes, in the middle of your tension spring assembly stud. And before assembly the disks were a little corroded and pitted so as the old 335 had a double tension assembly the spare disks were a perfect drop in again for this.

Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 (edited) These are the old pitted ones. This was needing taken off and cleaned as water had gotten in and rusted the inside. It has a small grub screw on the back holding it in. Edited December 29, 2018 by jimi Quote
Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 Right then, so everything was now back on the way it came. I tried it on a small piece of leather and it seemed like there was a lot of pulling going on underneath, so followed the thread path, pulling the thread through by hand and nothing?? so out with the bobbin basket again and look for burrs etc?? sanded, polished, sanded, polished...... nothing strange. tried again and same thing?? looked under the feed dog sanded, and same thing. tried the feed dog and plate from the old 335 and same again after e few stitches??? looked at where the thread was breaking and it seemed near the needle or just right under??? set the needle height again? same thing, so took out the new needle and put in another new needle the new needle must have had a burr on the eye! Needle had been hitting here at some time. Toe of foot broken off Needle clamp screw missing. this is the only metric thread i have found up until know. M3 Needle not hitting the bobbin case. they had a shorter needle in before. Quote
Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 (edited) Old bobbin case hit quite a few times with the needle. the other 335 bobbins do not fit in here?? looks like the wrong bobbin was put in?? Feed dog adjusted to the left just in case the thread was getting trapped there. Needle plate and feed dog from the old one on. this Accessory plate was also found a while back on ebay. it can be adjusted in height to match up with your needle plate. this is the other option to the binder plate and recessed one, but would need a half plate to complete. this is where the material/roller guide goes and possibly some types of binders. After the 2nd new needle was put in... Edited December 29, 2018 by jimi Quote
Members jimi Posted December 29, 2018 Author Members Report Posted December 29, 2018 So, Back with the setup that it came with and another try, seems like that toe has to be smoothed down before use?? Well, that is where it is at the moment. in need of a table,motor etc..and will probably be used just for binding at the moment but i have to move something out i think...hehehehe. Soren has sent some spare screws he found in a box and the bracket for the belt guard so when they get here i can update you on that if you like. Big thanks again to Danishman. As you have seen this pfaff was in good condition underneath and only needed a little cleaning and oiling, unlike the old one which had been abandoned and then thrown about by the courier service. This one was like a a day trip compared with the other journey . But i am sure there are some bad cases looking like new out there??? I hope this can help somebody if they are looking to do the same thing. Quote
