If damagedreplace immediately.9 Ensure replacement wheel is not damaged in any way such as cracks, deformations or splinters etc. Also check the mounting flangesfor deformation, burrs or chips. Damaged flanges must NOT be used as they may produce high stresses in the wheel causing it tobreak. DO NOT over tighten a wheel. Never tamper with a wheel in order to adapt it to a different size shaft.9 Install a new wheel as in 5.2.
