>> A << CAMSHAFT SPROCKET BOLT TIGHTENING
Use special tools MB990767 and MD998719 to prevent the camshaft sprocket from turning, and then tighten the camshaft sprocket bolt.
Scheme 396
- Tightening torque: 88 +/- 10 N.m (65 +/- 7 ft-lb)
Scheme 397
- Clean the hole in the crankshaft sprocket.
- Clean and degrease the mating surfaces of the crankshaft sprocket; sensing blade; and spacer NOTE: Degreasing is necessary to prevent decrease in friction between the mating surface due to presence of oil.
