Loosen the mounting bolt(south) belongings the belt tensioner using any special cam holding tools, while following the service manual. Practice not remove the tensioner completely unless replacing it. Instead, pin the spring-loaded tensioner away from the chugalug and so retighten the mounting commodities(s) to hold the tensioner in the loose position.
ii
Examine the tensioner caster for harm such as dents or cracks. Spin the tensioner pulley and mind for a rattle or humming noise that would indicate loose or worn bearings. Uneven vesture at the rear of the old timing belt could point a misalignment between the tension pulley and timing belt due to worn bearings.
- If any indications of harm or worn bearings are found, supersede the tensioner pulley. The permanently lubricated tensioner caster bearing can become dry, worn, loose, cleaved or can freeze up, and then the best exercise is to replace it, if it's not new.
