So couple questions on these pfaffs. 

Pretty much got it tore apart. Alot of stuff not too bad  shape, but alot of surface rust everywhere and some a little deeper but I think 95% is  salvageable. 

Two issues.

One is the  outer pressure foot bar which goes thru the top bearing under the pressure foot pressure spring (two leaf springs on top), that upper bearing I didnt realize those little bearing balls would just fall out when you removed the bar. Not sure if I got them all but anyways has anyone scene one of those bearing assemblies for sale or can you usually just replace those ball bearings and be good to go? Tiny little buggers. 

Second the hook is in pretty rough shape. Still gotta clean it but not sure how thats gonna play out. So looking at it has anyone ever replaced this with a 545/1245 hook assembly? Would be nice if I gotta buy parts to do a little modding to get a bigger bobbin. From pictures the hook assemblies look the same but I cant find any pics of the size comparison to see if the gears can be interchanged and how much adjustments to the hook assembly cage/block would be required. 

Thanks. 

 

Oh and one other thing, is there any disadvantage to switching to a 135x16 needle system ( I think the 145s are 190 or some other pfaff specific system) and how is that usually done? I would like to have the same needle system as my other couple of middle weight singers.

can´t help much but I´d compare the parts list of a 145 and 545 if the # are the same Haven't checked but I doubt they are the same. What is the Pffaf using I guess 134-35 / DPx35, right? No problem to switch to 135x16 needles you just have to raise the needle bar a tiny bit - not sure how much longer the 135x16 is but I´d guess 1 or 2mm

I also have set all my machines to 135x17 / 135x16 - no problems at all.

Hook assemblies for both Pfaff 145 and Pfaff 545 are readily available for around $80 on Ebay. I'm not sure if the 545 hook's bobbin is that much bigger to justify the effort of a retrofit. I took a few basic measurements off the hook from my Pfaff 545. You can compare them to your 145 dimensions and see if it's worth bothering.

The Pfaff 145 H3 uses 134-35 needles (My Pfaff 545 H4 uses the System 190 needles), according to the Pfaff 145 manual.

I bookmarked Constabulary's link to that needle vendor - nice comparison charts for the systems in question!

The 135x16 or 135x17 system is only 0.8mm longer in needle's butt-to-eye distance compared to the 134-35 system. That tiny difference might be compensated for via needle bar adjustment without any trouble, as Constabulary suggested.

Thank you guys much appreciated, 

Uwe great pics those will come in handy.

Uwe the pics you have spec the 545 at a M class bobbin, the 145 is a G class. Looks like everything else is the same with exception of the size. When I get time I am going to have to look at the parts and how they go together to see what would need to be modified to make it work. There is enough space in the cage area (not sure of name) but the diameter change will require adjustment and not sure if there is enough with the way the parts go together. Gonna look into it when I get to that point. Should be easy to do theoretically with the way the pfaffs are setup.

If you want to sell parts,  the upper bevel gear cover in particular I would be very interested.
