TechPulley sliding pieces SP08/SP2012-E
Often they are forgotten, but the sliding pieces in the variator are equally important as the rollers. In these sliders, the pressure plate moves constantly up and down. The guides should not jam, but certainly the clearance should not have too much. It is highly recommended to change the sliders to coincide with the rollers.
The sliding pieces are made of a similar abrasion-resistant nylon as the Dr.Pulley rollers, which promises a long life.
