Procedure In Replacement Of Primary And Secondary Pulley, Or In Replacement Of Primary Pulley, Secondary Pulley And Variator Chain
WARNING: This page is about a different variant/trim than selected.
- Measure depth "Lp" from the ST upper face to the primary pulley bearing catch surface at several points and calculate the average.
ST 499575400 GAUGE - Measure height "Ls" from the drive pinion retainer upper face to the secondary pulley bearing catch surface at several points and calculate the average.
ST 499575400 GAUGE - Calculate the following formula.
Calculation formula:
T (mm) = B + (Lp - Ls) + 31.601 - A
[T (in) = B + (Lp - Ls) + 1.224 - A]
T: Pulley alignment
A: Specified primary pulley dimension
B: Specified secondary pulley dimension
Lp: Depth from the ST upper face to the primary pulley bearing catch surface
Ls: Depth from the ST upper face to the secondary pulley bearing catch surface
