from oil and water. These parts should not be washed or 
immersed in solvent. Replace parts if contaminated. If 
there is oil or water on each part, check the front case oil 
seals, camshaft oil seal and water pump for leaks.
1. Mark the belt running direction for reinstallation.
2. Loosen the tensioner "B" bolt, and then remove the timing 

belt "B."
