PROCEDURE
INSTALL NO. 1 TIMING BELT IDLER SUB-ASSEMBLY
Install the No. 1 belt idler with the 3 bolts.
Tech Tips
| *1 | 13 mm (0.51 in.) |
| *2 | 36.5 mm (1.44 in.) |
The bolt lengths for bolt A, B and C as follows.
Bolt C is combined with the No. 1 timing belt idler.
| Standard Bolt | ||||||||
|---|---|---|---|---|---|---|---|---|
|
SET NO. 1 CYLINDER TO TDC/COMPRESSION
| *1 | Timing Mark |
|
Turn |
Using the crankshaft pulley bolt, align the groove of the crankshaft pulley with the timing pointer by turning the crankshaft clockwise.
Note
Do not turn the crankshaft pulley counterclockwise.
Set the timing and drive pulleys at each position.
Note
Make sure the engine is cold.
When turning the crankshaft or camshaft, the valve heads will hit against the piston top. Do not turn them more than necessary.
INSTALL TIMING BELT
Tech Tips
If reusing the timing belt, align the points marked during removal, and install the timing belt with the arrow pointing in the direction the belt moves when the engine is running.
Remove any oil or water on each pulley, and keep them clean.
Install the timing belt to the crankshaft timing and timing belt idlers.
| *1 | Timing Mark |
Using SST, slightly turn the injection pump drive pulley clockwise. Install the timing belt to the pulley, and align the timing marks of the drive pulley and timing belt case.
| *1 | Timing Mark |
Using SST, slightly turn the camshaft timing pulley clockwise. Install the timing belt to the timing pulley, and align the timing marks of the timing pulley and timing belt case.
Check that the timing belt has tension between the injection pump drive and camshaft timing pulleys.
Install the timing belt to the No. 1 timing belt idler.
Loosen the No. 1 timing belt idler bolt (A), and stretch the timing belt.
Slowly turn the crankshaft pulley.
Note
Always turn the crankshaft clockwise.
Tighten the No. 1 timing belt idler bolt.
CHECK NO. 1 CYLINDER TO TDC/COMPRESSION
Slowly turn the crankshaft pulley 2 revolutions from TDC to TDC.
Note
Always turn the crankshaft clockwise.
Check that the timing marks for each pulley align as shown in the illustration.
If the timing marks do not align, remove the timing belt and reinstall it.
INSTALL TIMING BELT GUIDE
Install the timing belt guide with the cup side facing outward.
INSTALL TIMING BELT COVER
| *1 | Gasket |
Install 2 new gaskets to the timing belt cover.
Install the timing belt cover with the 11 bolts and washers.
INSTALL IDLE PULLEY ASSEMBLY
Install the idle pulley bracket with the 2 bolts.
INSTALL CRANKSHAFT PULLEY
Align the key groove of the pulley with the pulley set key, and slide the pulley onto the crankshaft to install it.
| *a | Turn |
| *b | Hold |
Using SST, install the pulley bolt.
INSTALL VANE PUMP DRIVE PULLEY
