Thank you Gregg...your parts list with descriptions is EXACTLY what I needed to make sure I can order the right parts and refer to the parts correctly.
Thank you CD...got the arm shaft bushing out by placing a heavy-duty nail-puller bar on it and whacking it with a rubber mallet AFTER I made sure the 2 set screws were not in either hole. Arm shaft bushing with bearing are out. Had to use a gear puller to pull the housing and bearing the rest of the way off the arm shaft. The end of the shaft under the hand wheel was muggered up but the bearing/bushing didn't get scratched. I'll need to take emery paper to it to remove high spots and get it smooth again.
Thank you, Bob... I'm going to use stainless steel polishing rouge after the emory paper on the muggered-up areas on the arm shaft to make sure it is nice and smooth again for reassembly. All the washers and oil felt is missing along with the set screws. One set screw for the handwheel is missing. The order list is growing.
Thank you again CD...the timing belt (arm shaft connecting belt) will easily slide off the safety clutch pulley and then off the arm shaft pulley over the outer retaining split-ring. If I keep everything aligned, I shouldn't have to re-time especially since I'm not sure how to adjust upper and lower timing at this point.
To fix the broken part of the machine head I'm going the weld a small carbon steel plate to the face plate. We have a wire-feed welder and either me or hubby will practice on some similar thickness carbon steel and weld an extension piece to the face plate (which is also on the order list). I was thinking earlier of cutting a separate stainless cover and using existing threaded holes in the casting but I think a better idea is to use the jigsaw and cut a nice little carbon steel cover plate and weld it to the edge of the new face plate.
All the knee lifter parts are on my list to buy. I prefer the knee lifter on straight stitch machines and foot lifters on sergers. It seems the manufacturers designed their set-ups that way, too. So, the separate knee lifter assembly is on the buy list, too.
Concerning the arm shaft bearing and bushing: Previous owners had packed the ball bearings with bearing grease and removed the oil felt. (The only oil felt they left is in the lower feed mechanism.) I want to go back to the original intent. I think the bearings were packed OK but are a little dry with a lot of lint in the grease...I can see this isn't what the designers intended...if they intended that there would be grease fittings and bearing grease seals. So the plan is to the use oil again and add oil felts to the buy list. That's what the arm cap is for...inspect and add oil as needed. I'm thinking the bearing is OK...I can see some abrasions on each ball but the overall back and forth of it is a little loose but not too bad. I think it is OK unless you are thinking it shouldn't have any play.
There are lots of screws either missing or muggered-up in the feed mechanism area. Those will be replaced and installed as needed.
CD's parts list is showing a "reverse mechanism" and a "reverse feeding old-style". How do I know which style I could use? I'm thinking one or the other might have been made for the 226R at the time my Consew 225 was made and I can only know the date of manufacture from the serial number? My Consew 225 has serial number MH 6404074. Anybody got an idea or reference for the dates of manufacture of Consews and when the dates the old style reverse was used? I still think there is plenty of room to make this 225 into a 226R (after it is sewing great in the forward direction).
