REMOVAL SERVICE POINTS



<<A>> WATER PUMP BELT REMOVAL



caution
  • To reuse the water pump belt, draw an arrow indicating the rotating direction on the back of the water pump belt using chalk to install the same direction.
  • Hang the special tool drive belt remover (MB992276) on the vehicle components (including front sidemembers) using a cord and paper clip to prevent from falling.

1.Mount the special tool drive belt remover (MB992276) in between the water pump pulley and the water pump belt, then hold it with your fingers.

2.
caution Be careful that the finger holding the special tool MB992276 is not pinched.
Slightly turn the crankshaft pulley clockwise until the special tool MB992276 is pinched and held between the water pump pulley and the water pump belt.
3.If the special tool MB992276 is held, move the finger off.
4.
caution If the water pump belt is detached, be careful that the special tool MB992276 is also detached and fallen.
Slowly turn the crankshaft pulley clockwise until the water pump belt goes aground on the special tool MB992276 and is detached.
5.Remove the special tool MB992276.

<<B>> CRANKSHAFT PULLEY CENTRE BOLT REMOVAL



1.Use Front hub and flange yoke holder (MB990767) and Pin (MD998754) to insert the pin into the crankshaft pulley hole and prevent it from rotating.
2.Remove the crankshaft pulley centre bolt.

INSTALLATION SERVICE POINTS



>>A<< CRANKSHAFT PULLEY / CRANKSHAFT PULLEY WASHER / CRANKSHAFT PULLEY CENTRE BOLT INSTALLATION



1.If the crankshaft pulley is replaced, hit the dowel pin with a hammer to press-fit it to the position shown in the illustration.

2.Use Front hub and flange yoke holder (MB990767) and Pin (MD998754) to insert the pin into the crankshaft pulley hole and prevent it from rotating.

3.Use a waste to wipe off the dirt on the crankshaft pulley centre bolt, crankshaft thread hole and washer.
4.Use a waste to wipe off the dirt on the crankshaft pulley, the crank shaft and the oil pump drive shaft. Remove the grease on the portion shown in the illustration.
note Remove the grease in order that adhered oil cannot decrease the friction coefficient of the pressed area.
5.Install the crankshaft pulley.
6.Apply an appropriate and minimum amount of engine oil to the thread portion of the crankshaft pulley centre bolt and the lower portion of the flange.
7.Install the crankshaft pulley washer to the crankshaft pulley centre bolt.
8.Tighten the crankshaft pulley centre bolt to the tightening torque of 250 N·m.
9.Loosen the crankshaft pulley centre bolt fully.
10.Tighten the crankshaft pulley centre bolt to the tightening torque110 N·m again.

11.As shown in the illustration "A," apply the paint mark to the crankshaft pulley on the extended line of the corner adjacent to the one of the crankshaft pulley centre bolt corners.
12.
caution
  • If the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured.
  • If the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedures.
Tighten the crankshaft pulley centre bolt an additional 60°. Make sure the paint mark of crankshaft pulley centre bolt is aligned with the paint mark of crankshaft pulley as shown in the illustration "B."

>>B<< WATER PUMP BELT INSTALLATION




1.
caution Check that the notches of the notched pulley and the notches of the water pump belt are fit correctly.
Place the water pump belt onto the front step (rear 3 ribs area) of crankshaft pulley, slowly turn the crankshaft pulley clockwise with the water pump belt on the water pump pulley side held with your fingers to install the water pump belt.

2.
caution Hang the special tool drive belt installer (MB992288) on the vehicle components (including front sidemembers) using a cord and paper clip to prevent from falling.
Set the special tool drive belt installer (MB992288) to the crankshaft pulley.
note Slightly turn the crankshaft pulley clockwise until the special tool drive belt installer (MB992288) is pinched and held between the water pump belt and the crankshaft pulley.
3.Slowly turn the crankshaft pulley clockwise and install the water pump belt.
4.Turn the crankshaft pulley clockwise on several times and check that the water pump belt is installed in the water pump pulley and the crankshaft pulley securely.
