Poor metal surface preparation Note uneven finish and the presence of machining marks – no evidence of grit blasting.
The results of poor metal surface preparation – lagging debonds from the pulley shell – edge lifting and corrosion – corrosion of the pulley shell at the joints between lagging strips.

Correct pulley shell surface preparation is essential for good lagging adhesion. Grit blast to a 50-100 um surface roughness and check by measuring at multiple points across the pulley face and around the pulley circumference.
