3. Belt and Sheave Care
Proper belt tension and sheave alignment is vital to chipper performance. Here are a few problems
that can occur when belts and sheaves are not properly maintained or cared for.
Loose Belt: A loose belt will slip and then glaze over. Once this happens the belt will not transmit
power to the flywheel which can cause the chipper to clog and also cause excess sheave wear.
Misaligned Sheaves: When sheaves are not aligned properly the belts will glaze very quickly and
slipping will occur. This will also cause the belt to bounce or vibrate causing metal stress on the
machine.
