I got a leadscrew nut assembly (from Myford) for my Super7 and it does not fit (It's not even close). The dovetails at the back of the half-nuts are a completely different pitch than on my machine so I can't slide the nuts into my apron. Also, the nut inside appears to be a smaller diameter than my leadscrew (my leadscrew is about 0.75 inches in diameter). Is there more than one size for this part? My machine has a quick-change gearbox and I may not have told them that when I ordered. Would that matter? If anyone has a manual, the part Myford sent me is supposedly A1975/3ACC. This is the part that does not fit my machine.
Another part I ordered is the cloth wick that oils the spindle and a spring that appears to go in behind it (My machine does not have the glass oilers). The spring they sent is too large and doesn't fit into the hole (where the oil cup screws into the headstock). Again for those with documentation, the spring part is A3611/1. The part number matches my manual but the spring doesn't fit. I hope the answer is*NOT* that the spring somehow slides in from the back and I have to remove the spindle bearing to install it.
Anyway I have asked Myford these questions, but the last time I had questions, this group was much faster in responding than the factory. Any help would be greatly appreciated.
