Timing Belt: Service and Repair

REMOVAL AND INSTALLATION

Removal Service Points
[A] Power Steering Oil Pump Disconnection
Disconnect the oil pump (with the hose attached).

NOTE: Suspend the removed oil pump (by using wire or similar material) at a place where no damage will be caused during removal/ installation of the engine assembly.

[B] Engine Support Bracket Removal





Remove the engine support bracket in the numbered sequence shown in the illustration. Spraying lubricant, slowly remove the bolt (reamer bolt) indicated by the arrow.

CAUTION: Keep in mind that the reamer bolt is sometimes heat seized on the engine support bracket.

NOTE: Slightly jack up the engine body to make work easier.

[C] Crankshaft Pulley Removal





Using the special tool, remove the crankshaft pulley from the crankshaft.

[D] Timing Belt Removal

1. Align the timing marks.





2. Make a mark on the back of the timing belt indicating the direction of rotation so it may be reassembled in the same direction if it is to be reused.





3. Loosen the bolt of the timing belt tensioner.
4. Using a screwdriver or the like, turn the timing belt tensioner counterclockwise and tighten the tensioner bolt.
5. Remove the timing belt.

Installation Service Points
]A[ Timing Belt Installation





1. Align the timing marks of the camshaft sprockets (on the front and rear sides) and the crankshaft sprocket. (At the top dead point of the No. 1 cylinder compression stroke.)





2. First, route the timing belt on the crankshaft sprocket, then on the camshaft sprocket on the side without slackness in the tight side.
3. Next, run the timing belt onto the water pump pulley, the camshaft sprocket on the front side, and the timing belt tensioner.
4. Apply force counterclockwise to the camshaft sprocket on the rear side. When the tight side of the belt is fault, check that the timing marks are all aligned.

]B[ Timing Belt Tension Adjustment





1. Attach the flange.
2. Back off the fixing bolts of the temporarily tightened tensioner one or two turns and tighten the timing belt with the tensioner spring force.
3. Using the special tool together with the temporarily tightened crankshaft pulley bolt, turn the crankshaft two turns in the normal rotating direction (clockwise).

NOTE: Turn smoothly, but not in the opposite direction (counterclockwise).

4. Re-align the sprockets timing marks and tighten the tensioner fixing bolts.
Tightening torque: 22 - 30 Nm (16 - 22 ft. lbs.) (Tensioner fixing bolts)





5. Measure belt tension with a belt tension gauge at the indicated plate.
Standard value: 210 - 310 N (46.3 - 68.3 lbs.)

CAUTION: Contact the hooks to the tooth bottoms and the spindle to the back of the belt.

]C[ Timing Belt Lower Cover Outer / Timing Belt Upper Cover Outer (B) / Timing Belt Upper Cover Outer (A) / Timing Belt Cover Cap Installation





Since the mounting bolts of timing belt cover are different in size depending on location, insert them with care.

]D[ Crankshaft Pulley Installation





Using the special tool, attach the crankshaft pulley to the crankshaft.

]E[ Engine Support Bracket Installation





Since the mounting bolts of engine support bracket are different in size depending on location, insert them in numbered sequence.

CAUTION: When installing the reamer bolt, tighten it, slowly spraying lubricant on the reamer area.
