I need to install two tapered bearing races in a steering head.
First off let me say that with a few exceptions I hate dealing
with pressed in parts. Last time I had to do this I failed
miserably and took it down to the dealer.
I could order the 'special tool' to install them ($).
But now since I have a lathe maybe I should just make them.
From the manual description both races get installed at
the same time. I'd need 2 round disks/cones with holes in the
center. A threaded rod (got some 1/2 13) would draw them
together and pull in the races. There is a small flat area
before the taper starts.

Do I make a disk which just catches the flat area or do
I make a cone that fits into the taper? The dwg in the
manual doesn't look like a cone, but it look like it
has 2 diameters.

Is aluminum sufficient for the parts? I don't have any
steel that size. I'd probably only have to do this a
few times.

Thanks,
Wayne D.

Wayne-

An old mechanics trick is to slit an old race into a split ring (an abrasive
cut-off wheel does the necessary) and then use it as a driver. When the new
race is seated, the old one can easily be removed.
