Replacement Pulley Kits for Power Tech's CSI Caterpillar model quiet generator. These pulleys are only available as a kit. The reason behind this kit is these pulleys come pre-pressed with the two bearings and the shaft installed in the pulley. This is a difficult process that maybe unachievable without the proper tools and knowledge. Do you have a KSI with a Kubota engine? Click Here.
