WHEELS, RIMS AND TIRES
Figure 38.
INSTALLATION, TIGHTENING AND ALIGNMENT
OF DISC WHEELS AND RIMS
When installing disc wheels or demountable rims with
cast spoke wheels, be certain that the threads on studs
and nuts are clean to permit correct torquing of nuts.
The mounting surfaces of rims, wheels, spacer rings and
clamps are free of dirt, rust or damage.
Use a wire brush to clean mounting contact surfaces. Do
not use lubricant on threads.
After rim or wheel has been properly torqued, it should
be checked for alignment. This can be accomplished by
rotating wheel with a piece of chalk attached to a steady,
firm surface and placed to just barely clear outside
surface of tire bead seat. This procedure will point out
the "high spot." Keep in mind, however, that a "high
spot" does not necessarily mean that lug nuts have been
unevenly tightened. This condition or misalignment can
also result from a bent wheel.
The checking of the alignment of the wheel/rim
installation is more important on cast spoke rims since
the rims can be drawn out of alignment when improperly
tightened. Therefore it is important that the following
installation procedures be followed.
Disc Wheels With Conical Nuts
1.
Slide inner/rear or front tire and wheel in position
over studs and push back as far as possible.
Use care to avoid damage to threads on studs
and inspect the valve stem to caliper for
clearance.
2.
Install the outer wheel nut on front wheels and
inner wheel nut on rear dual wheels. Run nuts
on studs until the nuts start to contact the wheel.
Rotate wheel a half turn to allow parts to seat
naturally.
