Vernier Caliper High accuracy (0.02mm), battery-free — Users without power sources or who prefer manual measurement
Ruler + Tape Measure Common household items, no extra purchase needed — Temporary measurements, users without calipers
Marker Pen + White Paper Auxiliary measurement to minimize errors —Used with ruler/tape measure

Common Mistakes to Avoid

Incorrect operation Directly striking with a metal hammer — may cause deformation or cracking of the dust cap
Incorrect operation Forcing installation despite slightly undersized fit — may lead to loosening during operation and compromised sealing
Incorrect operation Installing with contaminants present in the wheel hub — may result in water ingress through gaps and bearing corrosion
Incorrect operation Forcibly correcting after tilted pressing — may damage the sealing ring and render it ineffective
Correct Procedures Use a rubber mallet + soft cloth, or specialised installation tools
Correct Procedures Replace with a dust cap of matching dimensions
Correct Procedures Thoroughly clean + deburr any rough edges
Correct Procedures Remove the dust cap and reinstall with proper alignment
