OK another confession of a noob wrench.

so installing the new clutch and alum flywheel.

first adjusted the bracket to set the clearance on the speed sensor to the starter ring.

then adjust the pin on the new flywheel to the correct clearance on the crank sensor.

well....

as I was trying to put on the bell housing for what would have been the final fitting, it would not go. finally figured out the flywheel pin was set way too long and it would not clear the bell housing.

when putting in the sensors to set the clearance, I got them mixed. so with the washer on the crank sensor now on the hole for the speed sensor I actually set the bracket way to high.

what I suspected as the delta appeared to be exactly twice the thickness of that washer. but just finished looking at PET and the WSM ... AGAIN ... to confirm my bone head move. Ironically, I had actually looked it up in the WSM at the time, but still went and put them in reversed.

initially I had been able to put on the bell housing, as the pin was still up around the sensors. glad I had pulled it back off and turned the pin down to remove the tape I put on to hold while the loctite set.

so heed the warning to have the FLYWHEEL PIN FACING STRAIGHT DOWN when you put on the bell housing. when I saw that note in the procedure, I thought 'why'. now I know. that way you will know if it is too long. the lower area of the bell house has the least clearance to the flywheel.

I just cringe at the thought of having buttoned it all up with that pin too long. hit the starter and no telling what noise and damage the impact of the pin on the bell housing would have caused.

once again, hope to save someone else from making the same mistakes I have.
