Pic. 4.56. Dynamic Tensioner: 1 - bolt, 45 Nm; A - mark of the maximum stretching of the belt; B - mark for belt tension control (applied to the engine); C - zero stretch mark; D - hole for installing a pin with a diameter of 4 mm
Using the special lever 0188-Z, compress the spring of the dynamic tensioner, this will reduce the belt tension (pic. 4.56).
Using special tool 0188-Q1, fix the dynamic tensioner in this position. Instead of tool 0188-Q1, a 4 mm pin can be used.
Remove the accessory drive belt from the pulleys.
Check that the idler roller and idler roller of the dynamic tensioner rotate evenly and smoothly.
Installation
The marking system on the dynamic tensioner allows you to control the extension of the accessory drive belt. The combination of marks A and B indicates the need to replace the belt.
Slide the belt over the crankshaft and accessory pulleys and lastly over the idler pulley.
Make sure the belt is correctly positioned on all pulleys and roller.
Using the special lever 0188-Z, compress the spring of the dynamic tensioner and remove the special tool 0188-Q1 or pin with a diameter of 4 mm and remove the lever, while the tension roller of the dynamic tensioner will tension the auxiliary drive belt.
Further installation is carried out in the reverse order of removal.
