Camshaft Timing Drive Design Identification

Camshaft Timing Drive Design Identification


Third Design




* Timing chains are identical to second design.
* The camshaft position actuator sensors are a new design.
* The camshaft position actuators incorporate new sensor wheels that correspond with the new design of camshaft position actuator sensors.




Fourth Design




* New secondary timing drive chains, inverted tooth (IT) design.
* The camshaft position actuators incorporate new sprockets that correspond with the use of IT chains on the secondary timing drive system.
* The intake camshaft position actuators are different for the left and right sides.
* The left and right secondary timing drive guides are new due to the use of IT chains on the secondary timing drive system.
* The intermediate timing drive sprockets are new due to the use of IT chains on the secondary timing drive system.
* New intake camshafts.
* New fourth design IT primary timing drive chain.
* New fourth design IT crankshaft sprocket.
* Fourth design IT primary chain is not interchangeable with second and third design.
