Hey guys, can a tool (drill bit etc) only go through the shaft if the shaft is in the proper position? I assume the hole in the shaft is offset so that the shaft can't be 180* off. Is that a proper assumption?

TIA!

 

If I am understanding your post (terminology is often used differently) you are asking about the hole in the back of the block for holding the shaft in place, if that's the case then I believe there is only one hole and a screwdriver or drill bit can be used easily to keep it aligned while you are doing your timing belt change. Make note of the crank position and if it's at TDC then you know you've got it right.

 

That's pretty much right. I had to rotate the shaft to clean it (long story) so I am wondering of the hole in the shaft is offset so that a tool *cant* be inserted all the way if the shaft is 180 degrees off.

 

To the best of my knowledge on a 93 that is true. To verify that you have it right just check the marks on the crank shaft pulley.

 

nasty is correct. Whatever rod you are using will only plunge through the shaft if the shaft is in the correct position.

(Note that there are some shaftpositions where you might THINK that the rod is as deep as it can go, but there is only one where the rod will push right in deeply. If you have any question about that, justtry a small-diameter rod to verify you've got the shaft in the correct position, then go a bit bigger so that there's not much rotational"play" in the shaft position. I used the bit-end of some high-speed drill bits. That way, I could easily change diameters at will.)
