PROCEDURE
INSTALL NO. 1 TIMING BELT IDLER SUB-ASSEMBLY
Temporarily install the No. 1 timing belt idler sub-assembly and idler tension spring with the 3 bolts.
Tech Tips
The bolt lengths for bolt B and C are as follows.
Bolt A is combined with the No. 1 timing belt idler sub-assembly.
| Item | Length |
|---|---|
| B | 40.0 mm (1.57 in.) |
| C | 76.5 mm (3.01 in.) |
Tighten bolts A and B.
Tighten bolt C.
SET NO. 1 CYLINDER TO TDC/COMPRESSION
| *a | 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.
| *a | 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 injection pump drive pulley and timing belt case sub-assembly.
| *a | Timing Mark |
Using SST, slightly turn the camshaft timing pulley clockwise. Install the timing belt to the camshaft timing pulley, and align the timing marks of the camshaft timing pulley and timing belt case sub-assembly.
Check that the timing belt has tension between the injection pump drive pulley and camshaft timing pulley.
Install the timing belt to the No. 1 timing belt idler sub-assembly.
| *a | Turn |
Loosen the bolt, and stretch the timing belt.
Slowly turn the crankshaft timing pulley.
Note
Always turn the crankshaft timing pulley clockwise.
Tighten the bolt.
CHECK NO. 1 CYLINDER TO TDC/COMPRESSION
Slowly turn the crankshaft timing pulley 2 revolutions from TDC to TDC.
Note
Always turn the crankshaft timing pulley 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.
