1) Always replace the center bolt. 2) Two turns of 90 are permissible. - Using 8 mm hex wrench, turn toothed belt tensioner roller -1- counter-
clockwise, opposite direction shown (arrow) until tensioning lever -2-
compresses tensioner -3- so that spring clamp can be removed and
then remove clamp.
- Before starting engine, pre-load timing tensioning roller as follows:
- Using a torque wrench with 8 mm hex bit, apply tension to toothed
belt clockwise in direction shown (arrow) until a torque of 15 Nm is
attained. This ensures tensioner has expanded completely and is
properly engaging toothed belt. Component
