Originalersatzteil

for rear driven pulley, original thickness

For driven pulley, rear, consists two reinforced springs, their higher pressure ensures a higher rpm. At the same time prevents the belt from slipping off.
Not allowed for the RTLR (StVZO)!

reinforced, for pulley in the rear converter, causes a higher pressure and thus a higher speed. At the same time prevents slipping of the V-belt.
Not allowed for the RTL (StVZO)!

For rear, incl. sliding ring bearing. The contrast spring sits no longer on the converter - V- belt pulley when attaching the sliding bearings, which prevents spring twisting. This will significantly reduce the usual vibrations, further this sliding ring causes a substantially better shifting behavior, as well as a quieter motor

Reinforced, for pulleys in the rear converter, causes a higher contact pressure and thus a higher speed. Also prevents the V-belts from slipping.
Not StVZO approved

Different spring rates determines the clutch rpm, the stronger the spring, the higher the rpm.

Für Riemenscheibe im hinteren Wandler, bewirkt einen höheren Andruck und dadurch eine höhere Drehzahl. Verhindert gleichzeitig das Durchrutschen des Keilriemens.
Nicht StVZO zugelassen
