Dr.Pulley sliding pieces SP1917-N
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.

Didnt do the job so i had to use the old set . I ordered the SP1917-N but the set i received had a different number on the sticker and the 1917 was written with pen . I dont know if it was a mistake on the sticker or it is one size for varius numbers .
The fact is that the pieces stuck when i put them in their place and didn't let the variator work .
The scooter is an Aprilia sportcity 125 model 2007 .
