Thanks Warren, ?i got the Arceurotrade drawing and parts list. ?And thanks Gagetbuilder your drawings for the Dog clutch show there is a 0.270 diameter shaft inside the part #26 shaft as ?i suspected there had to be even though the expanded drawings do not show this internal shaft. ?
Apparently the grease finally dried out on this internal shaft so the part #26 shaft seized and stopped my lathe.
?Now come the fun part of getting the seized shaft off the internal shaft.
Thanks for the help

This is the same drawing I have except for the European style
poser plug (and it's a better copy).

Hi
Warren
?In
my manual for the 33684 model of the
Harbor Freight lathe the shaft #46
goes through the 45 tooth gear part
number 45 then through what looks
like a washer #22 then through the
quadrant plate #36 and ends in the
backing plate made of pot metal
where it looks like it is peaned to
hold it in a fixed non rotating hold
in that plate. ?The quadrant plate
and 45 tooth gear should turn
independently on that shaft #46.
I
was hoping someone on the list could
confirm this or point out the error
of my observation. ?If i am right i
will have to replace the shaft, gear
and backing plate after i rip the
existing shaft out of the backing
plate which will destroy then but
salvage the quadrant plate and
washer.
I hate to destroy something if
there is a better way to fix this
seized gear.
Thanks for the help

Pete, I dont have a 7x10
but have collected up the HF
manuals and after looking at
three of them, it appears
that the gear in question
comes off with that "brass"
bearing mount (Drawing # 48
if you have the manual) that
is just in front of it.?
That gear seems to be
mounted on a short shaft
that connects it to the
smaller gear in front of the
retainer.? Both gears are
keyed to the shaft.
I
suspect what you see peened
over on the back side is the
pivot for the
forward/reverse quadrant
(Part #36 called handle
mount).
I'm not even sure the
gear shaft goes into the
casting.
From
here, it looks like it would
be easy enough to pull the
change gears and the mount,
and see if the offending
gear comes with it.
From
the description you gave for
the failure, my best guess
would be the bearing in the
mount failed.? I believe
Little Machine Shop lists
all of those parts.
......again, best guess
from the manuals.......

The
reversing gears on my
7x10 harbor freight
lathe33684 have seized.
Specifically the black
45 tooth gear shown in
this picture.
Does
this gear just pull off
or is there a sleeve on
this shaft the should
come off first?
The
shaft seems to be
pressed into the
potmetal frame behind
the gear and peaned so
it should not come off.
Any
help would be
appreciated.
Thanks
Pete
