That is a problem I have never had unless the seal was bone dry, in which
case it will quickly self-destruct anyway. Wet seals that are properly
sized don't get hot. Nor do they wear

The bearings should have about a 20% fill. Don't fill the bearings full.

Hi All
I finely got my lathe working and by the third part the spindle bearings
start to seize. Its a brand new BVC25A belt driven lathe. I managed to
pack some grease in the back bearing when I first started with the build
but there is no way to get to the front bearing.
Does anyone know how

That looks like a very close relative of mine.
On mine there were oilers on top of the head casting. Once I removed
the oilers and drilled the holes deep enough to reach the bearings I
had a way to inject
So a little bigger tap with a little bigger mallet did the job. The
front bearing fell apart and is badly worn.
Now the seat is stuck inside the headstock and the bearing piece is
stuck to the shaft and I have no idea how to get it out.
Anyone know how to get a stuck bearing seat out please?

Where there is no provision for pressing out I use a dremel and grind
a slot to weaken inner or outer, needs care and a steady hand but has
got me out of trouble a few times.

Never heard of that lathe. Does it have an oil bath in the headstock like a

Also when I have a really bad stuck bearing race I usually run a tig weld
around the OD of it and that usually frees it up and often cracks it enough
to just hit it with a chisel and mallet and it falls off. I am sure you
probably don't have a tig welder but if you cannot get it off you might

I found on my lathe that the back gear is used as an oil slinger. The
problem is that I don't use the back gear much, so the gearbox
Mine was also taper roller bearings. The front one was very badly worn.
You should have earned me before but once this is sorted out it should
be OK I hope.
