INSTALLATION SERVICE POINTS ►A◄ BALANCER TIMING BELT/BALANCER TIMING BELT TENSIONER INSTALLATION

1.Ensure that the crankshaft balancer shaft drive sprocket timing marks and balancer shaft sprocket timing marks are aligned. 2.Install the balancer timing belt on the crankshaft balancer shaft drive sprocket and balancer shaft sprocket. There should be no slack on the tension side.

3.Assemble and temporarily fix the center of the pulley of the balancer timing belt tensioner so that it is at the top left from the center of the assembling bolt, and the pulley flange is at the front-side of the engine. 4.Adjust the balancer timing belt tension.

►B◄ BALANCER TIMING BELT TENSION ADJUSTMENT When tightening the mounting bolts, ensure that the tensioner does not rotate with the bolts. Allowing it to rotate with the bolts can cause excessive tension of the belt.

1.Lift with your fingers the balancer timing belt tensioner in the direction of the arrow. Apply a tensile torque of [3.0 ± 0.4 N·m (26 ± 4 in-lb)] to the balancer timing belt so the belt is tense without any looseness. Tighten the assembling bolt to the specified torque in this state. Then, fix the balancer timing belt tensioner. Tightening torque: 19 ± 3 N·m (14 ± 2 ft-lb)

2.Turn the crankshaft clockwise two turns to set number 1 cylinder to TDC of its compression stroke and check that sprocket timing marks are aligned.

3.Apply a pressure of approximately 100 N (22 pounds) at the center (arrow area) between the sprocket as shown in the figure, then inspect whether the belt deflection is within the standard value. Standard value: <When adjusting> 5 - 7 mm (0.20 - 0.27 inch) <When replacing> 5 - 7 mm (0.20 - 0.27 inch) 4.If not within the standard value, adjust the belt tension again.

►C◄ CRANKSHAFT ANGLE SENSING BLADE/CRANKSHAFT CAMSHAFT DRIVE SPROCKET/CRANKSHAFT PULLEY WASHER/CRANKSHAFT PULLEY CENTER BOLT INSTALLATION

1.Clean or degrease the crankshaft, the crankshaft angle sensing blade, the crankshaft camshaft drive sprocket and crankshaft pulley washer as shown. NOTE: Also clean the degreased surfaces. 2.Install the crankshaft angle sensing blade and crankshaft camshaft drive sprocket in the direction shown. 3.Place the larger chamfer side of the crank shaft pulley washer in the direction shown in the Figure and then assemble on the crank shaft pulley center bolt. 4.Apply a small of engine oil to the crank shaft pulley center bolt bearing surface and screw.

5.Hold the crankshaft camshaft drive sprocket with special tools MB991367 and MB991385 in the same manner as removal. 6.Tighten the crankshaft pulley center bolts to the specified torque. Tightening torque: 167 N·m (123 ft-lb)

►D◄ TIMING BELT TENSIONER ADJUSTER INSTALLATION 1.Set according to the following procedures when the timing belt tensioner adjuster rod is fully extended. If the compression is too fast the procedure may damage the rod. Make a point to slowly and thoroughly compress.

(1)Slowly compress the timing belt tensioner adjuster rod using a press or vice, then align the set hole A of the rod with set hole B of the timing belt tensioner adjuster cylinder.

(2)Insert a wire or pin in the set hole aligned. NOTE: When replacing the timing belt tensioner adjuster with new parts, the timing belt tensioner adjuster is set with a pin. 2.Install the timing belt tensioner adjuster to the engine and then tighten the mounting bolt to the specified torque. Do not remove the wire or pin until the tension of the valve timing belt is adjusted. Tightening torque: 23 ± 3 N·m (17 ± 2 ft-lb)

►E◄ TIMING BELT TENSIONER PULLEY INSTALLATION

Temporarily tighten the timing belt tensioner pulley as shown.

►F◄ VALVE TIMING BELT INSTALLATION

1.Align the timing marks on the camshaft sprocket, crankshaft camshaft drive sprocket and engine oil pump sprocket.

2.Adjust the timing mark of the engine oil pump sprocket. Unplug the cylinder block plug. Insert a bolt (M6, section width 10 mm, nominal length 45 mm) from the plug hole. If the bolt comes in contact with the balancer shaft, turn the engine oil sprocket one rotation. Re-adjust the timing mark and then check to see that the bolt fits. Do not remove the bolt until the valve timing belt is assembled.

3.Incorporate the valve timing belt in the following manner so that the tensile force of the belt is not lax. (1)Place the valve timing belt on the timing belt tensioner pulley and crankshaft camshaft driver sprocket and then support it with your left hand so it does not slide. (2)Place the valve timing belt on the engine oil pump sprocket while pulling it with the right hand. (3)Place the valve timing belt on the timing belt idler pulley. Incorporate the valve timing belt. Then apply reverse rotation (counterclockwise rotation) pressure to the cam shaft sprocket. Re-check to see that each timing mark is aligned while the tension side of the belt is right. (4)Place the valve timing belt on the camshaft sprocket.

4.Turn the timing belt tensioner pulley in the direction shown in the figure using special tool MD998767 to apply tension to the valve timing belt. Then temporarily tighten and fix the timing belt tensioner pulley mounting bolt.

5.Check that the timing marks are aligned.

6.Remove the bolt inserted in Step 2 above, then assemble the cylinder block plug. 7.Tighten the cylinder block plug to the specified torque. Tightening torque: 30 ± 3 N·m (23 ± 2 ft-lb) 8.Adjust the valve timing belt tension.
