CAUTION! 
     
Before removing toothed belt, note direction 
of rotation with chalk or felt-tip marker. 
Reversing the direction of rotation of a used 
belt can destroy the belt. 
    
-  Loosen tensioner (arrows) and lift toothed belt from camshaft gear.
-  Use 3036 Retainer to loosen camshaft gear.
- Remove camshaft gear. 
    
-  Thread camshaft gear retaining bolt (arrow) into camshaft by hand until 
stop to guide 2085 seal puller. 
-  Unthread inner part of 2085 seal puller two turns (approx. 3 mm or 0.12 
in.) and secure using knurled bolt.
