STANDARD PROCEDURE - LOCKING ENGINE 90 DEGREES AFTER TDC




1. Disconnect negative battery cable.
2. Remove the accessory drive belt. (Refer to 7 - COOLING/ACCESSORY DRIVE/DRIVE BELTS - REMOVAL)
3. Rotate the engine until the VM 9892 Crankshaft locking tool can be installed. Install the VM 9892 Crankshaft locking tool into the left side of the engine block, slightly rearward of the left engine mount. Make sure that the outer portion of the tool threads into the block and the bolt threads into the crankshaft. If the bolt does not thread into the crankshaft, the crankshaft is not at 90 degrees ATDC.


4. Remove the front lifting bracket.


5. Remove the Idler pulley bracket.


6. Remove the CMP sensor (1).
7. Remove the upper front cover (2).


8. Remove the camshaft oil seal to expose the camshaft tone wheel.


9. Install the camshaft locking tool onto the camshaft position sensor tone wheel.
10. The engine is now locked at 90 degrees ATDC.

NOTE: If it is suspected that the camshafts are not correctly timed to each other, the valve cover must be removed to allow the verification of camshaft timing. When the dots on the back of the camshafts are lined up, the camshafts are correctly timed to each other. The engine is NOT timed to 90 degrees ATDC with the camshaft dots lined up. Use the camshaft timing tool to set the camshafts to 90 degrees ATDC.



NOTE: When the camshafts are correctly timed to each other and turned to 90 degrees ATDC, the camshaft marks are positioned as shown in the illustration to the right.
