If you look at one of the download PDF's on the link below you will see the
various popular replacements parts for the 7 series machines
I dont know the exact answer to your half nut problem but there might be a
difference between the aprons of S7's with power X feed and others. There
was a change to apron design after machine SK108891 [ so the Ian bradley
manual shows. Did you tell them your machine type & number when ordering.?
sometimes the ladies at myford dont ask and are not aware of the different
machine types. getting through to someone in the know in the shop is like
getting through to the pope! but persevere.
Again looking at the Bradley book the Wick oiler is accessed via a hole
that runs from 7 oclock bottom left of the headstock when looking at it
from the tail stock. This I think means lifting of the headstock
completely! The oiler feed passage from the cup runs from 9 oclock to the
top of the oiler passage above. The oiler wick passage seems to be a bigger
diameter than the oil feed passage
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
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.
