I had the main pulleys off the front of the motor today, including the "crank sensor plate" and didn't think to note the plate's orientation before removing it. There are two possibilities to orient it upon installation -- each 180 degrees apart. Amazingly the FSM doesn't mention anything about it, and there are no obvious markings.

How do I orient this damn thing?

 

Of course right after posting this I figured it out. Posting here for future searchers...

There is a very small key cutout on the sensor plate that needs to align with a marking on the front of the crankshaft/eccentric shaft (see picture).





Also in my case there was what appears to be white paint around one of the alignment posts (see first image above), and some of it transferred to the back of the sensor plate last time it was installed.

 

yep, it only goes on one way, unless you get the drill out, and i have actually seen that.

 

Yep. If you have it 180 out the bolt holes won't line up.
