• Repeat the side and radial trueness checks until a maximum error
of 0.4 mm is obtained.
• Balance the wheel as described in para 9.1.
• Alternate nut tensioning and trueness and circularity check
until correct spoke tension is obtained and a maximum defor-
mation error within the following limits:
- centering (axial offset): 0.3 mm
- circularity (radial offset): 0.4 mm
• Repeat balancing and correct again, if necessary, until the wheel
is properly centered (Fig. 27).
9.1 - BALANCING THE WHEELS
WARNING!
This is one of the most important stages in assembling the wheel.
Incorrect balancing may damage the wheel or cause the wheel
to unexpectedly fail, resulting in an accident, personal injury or
death.
• To carry out this operation, the wheel must be fitted on a very rigid
wheel centering support (A).
• Spoke after spoke, pull the rim forcefully with both hands from the
side opposite the spoke (B - Fig. 28) to balance.
• Repeat the operation from the other side of the wheel (Fig. 28).
