REMOVAL SERVICE POINTS

 
 
<<A>> DRIVE BELT REMOVAL
To introduce the serpentine drive system with the auto-tensioner, the following operations will be required.
 
1.
warningBe sure to set the tool to the hexagonal part securely to prevent the tool from falling off because the tension of the auto-tensioner is high.
Securely set the tool to the hexagonal part of the auto-tensioner.
2. Rotate the auto-tensioner anti-clockwise.
3. Insert the L-shaped hexagon wrench into the auto-tensioner hole to fix the auto-tensioner.
4.
cautionTo reuse the drive belt, draw an arrow indicating the rotating direction on the back of the belt using chalk to install the same direction.
Remove the drive belt.
 

 
 
<<B>> CRANKSHAFT PULLEY CENTRE BOLT/CRANKSHAFT PULLEY WASHER/CRANKSHAFT PULLEY REMOVAL
 
1. Use the following special tools to support the crankshaft pulley:
  • Front hub and flange yoke holder (MB990767)
  • Pin (MD998719)
2. Loosen the crankshaft pulley centre bolt and remove the crankshaft pulley washer and crankshaft pulley.
 
 
 
<<C>> ENGINE AND TRANSMISSION ASSEMBLY HOLDING
Install a special tool for holding the engine and transmission assembly.
 
1. Install special tool engine hanger plate (MB991956) to the cylinder head.
 
2. Hold the engine and transmission assembly using the engine hanger (Special tool: MB991895) and engine hanger attachment (Special tool: MB992906).
noteSlide the front foot of special tool engine hanger attachment (Special tool: MB992906) to balance the engine hanger.
 
3. Install the chain of special tool engine hanger balancer (MB991454) and special tool engine hanger (MB991527), and set the chain block.
 
 

 
 
INSTALLATION SERVICE POINTS
 
 
>>A<< CRANKSHAFT PULLEY/CRANKSHAFT PULLEY WASHER/CRANKSHAFT PULLEY CENTRE BOLT INSTALLATION
 
1. Wipe off the dirt on the crankshaft sprocket, crankshaft and crankshaft pulley as shown in the figure using a rag, and then degrease the areas.
noteDegrease them to prevent drop in the friction coefficient of the pressed area which is caused by oil adhesion.
2. Install the crankshaft pulley.
3. Wipe off the dirt on the crankshaft pulley washer and the crankshaft pulley centre bolt as shown in the figure using a rag.
4. Apply an adequate and minimum amount of engine oil to the thread of the crankshaft pulley centre bolt and the lower area of the flange.
 
5. Use the following special tools as during removal to support the crankshaft pulley:
  • Front hub and flange yoke holder (MB990767)
  • Pin (MD998719)
6. Tighten the crankshaft pulley centre bolt to the specified torque.
Tightening torque: 110 N·m
 
7. As shown in figure A, put a paint mark on one angle of the crankshaft pulley centre bolt. Then, put a paint mark on the crankshaft pulley on the extended line of the angle next to the marked angle.
8.
caution
  • When the tightening angle is smaller than the specified tightening angle, the appropriate tightening capacity cannot be secured.
  • When the tightening angle is larger than the specified tightening angle, remove the bolt to start from the beginning again according to the procedure.
Tighten the crankshaft pulley centre bolt in a 60°, and check that the paint mark on the crankshaft pulley centre bolt aligns with the paint mark on the crankshaft pulley as shown in figure B.
9. Loosen the crankshaft pulley centre bolt completely after steps 6 to 8, and then repeat steps 6 to 8.
 

 
 
>>B<< DRIVE BELT INSTALLATION
 
 
1.
caution
  • To reuse the drive belt, install it by aligning the arrow mark on the backside of belt marked at the removal with the rotating direction.
  • Check that the notches of the notched pulley and the notches of the drive belt are fit correctly.
  • Check that the drive belt is installed in the centre of the flat surface of the flat pulley.
Install the drive belt to each pulley as shown in the figure.
 
2.
warningBe sure to set the tool to the hexagonal part securely to prevent the tool from falling off because the tension of the auto-tensioner is high.
Securely set the tool to the hexagonal part of the auto-tensioner.
3. Rotate the auto-tensioner anti-clockwise and remove the L-shaped hexagon wrench fixing the auto-tensioner.
4. Apply tension to the drive belt while slowly turning the auto-tensioner clockwise.
