10. Center the spindle hub assembly (1) on the
square tube where the saddle cut was made.
Position the hub so the top edge is raised 1/4"
above the top surface of the tube. Make sure
the centerline of the hub is 13 7/8" from the
front surface of the square tube.
11. Clamp the spindle hub assembly (1) in place
and make sure it is plum with the upright
square tube (2). Clamp only to the outside of
the hub.
Note: Make sure the measurements are accurate
and the hub is plum with the tube. Securely clamp
the hub in place before welding.
12. Cover the openings of the spindle hub assem-
bly (1) so not to allow any welding sparks or
beads to get inside. This is necessary in order
to protect the bearing cups on the inside of
the hub.
13. Weld the spindle hub assembly (1) in place
using a weld with high tensile strength.
Refer to Figure 4
