but I will not be bringing the car to a shop

I don't want to be disagreeable but, I will disagree here. The timing 
belt 
change is straight-forward and is only remarkable by the occasional 
screw-up -- look for another shop that can remove a seal without 
incident. 

The original post also said he was going to have the timing belt service 
done, which I interpret as not a DIY job, but it is necessary that he 
assemble 
the parts. 

"I've had no problems with timing sensors" places David in the minority 
and I would not use the exception to guide my PM decisions. If it is 
a DIY 
job, changing the CPS with a BBAutoMacao sensor is cheap insurance, 
or, conversely, if you always carry your tools and an occasional no- 
start 
episode is no problem, just wait and do it in the parking lot. 
However, if 
you must have it towed to the mechanic and then obtain the part and pay 
his labor, better change it now even if you have to buy a genuine part. 

I have three vehicles, so the decision to keep a spare crank pulley gear 
is a no-brainer. Plus, I don't want to get bogged down in the middle 
of the 
job having to order a part -- and pay a premium because I want it 
right away. 
I don't automatically use the new part, but I give it a dye-penetrant 
crack 
inspection before re-use. 

You could have also just said "torsen" or "anti-sieze" rather than 
ask Mr. 
Chips for crack stories. Most weren't around for the last belt 
change, so 
the circumstances that caused it are mostly guesswork. And, as the sage 
once remarked, "if you've seen one crack, you've seen them all". : > )
