Hi I was unable to move the needle at all using the hand wheel so was unable to check the alignment of the needle as you spoke of
Check the hand wheel. There should be a smaller wheeel in the center of the hand wheel. Make sure it is locked in(turn center wheel clockwise or could be counter clockwise til snug)
SOURCE: needle wont go up and down.
well,it seem that your upper camshaft was stuck due to several factor on mechanical linkages and maybe on gears.You have to isolate the checking since you have clean lower bobbins free from dirt and thread/fabrics chips.If there an opening on top of machine open it to check some mechanical destorsion or breakage.Check some broken gears inside.If nothing try to open also at the bottom of machine cover and there are also belt and gears connected to the motors and bobbins shuttle holder if so oil all shafting oil port,oil port bushing specially on bushing near hand wheel there is port for oil,
check also motor assembly of machine,you can disconnect belt from motor release the bolt holding motor adjust to lower tension belt and release the belt.Take some tools such as monkey pliers or small pipe wrench that can hold hand wheel just crack in order to move suddenly after oiling for several hours sometime bushing and shafting rushes emerged or if you have anti rush spray put in on.After cracking and you can move a little crack only by your hand several time lleft and right until all linkages free from rush.If you can move all parts and hand wheel rotate freely.Check also motor by rotating the small pulley conncted to motor if free to move.if ok put back and reassembly all parts disconnected.try to move again by hand if free to move after all asssembly.Run machine using foot pedal.
