240z Distributor help

[240260280z]

Well i have bad news, I got the motor in the car and running today but i cant seem to bring the timing to the 5 degree mark.

Take a look at these and look where the tang points relative to the 6mm threaded hole:

Looks like you may be a tooth off on the spindle to drive gear making it too retarded (ccw).

This is what I'm referring to supporting the cam tensioner. The attached file is a couple of pages from How to Rebuild Your Nissan & Datsun OHC Engine.

The wooden block is what your talking about in the rebuild guide?

Yeah i may be off one tooth. Damn!!!! so does that mean i have to unbolt the oil pump and restab the spindle?

Yes, it is.

gotch yah. when i had the front cover off i just put the chain on with the cam and the crank shaft, then i put the tensioner on. So i didnt have to have any support to hold the tensioner from coming out.

You may want to purchase the book to give you some guidance, with one caveat: get your torque specs from the FSM. I seem to recall some of the torque specs being off in the book.

kool i got it figured out. have full adjustment within the timing marks range. works great now. just needed to rotate the distributor/oil pump shaft one tooth over. thanks for the help everyone!!

I know this is an old thread but.. I am having the same issue, Did you move it a tooth CW or CCW?

Somebody on this site has described a way to adjust the quill from the top.  I think it might have been CO.  Used some sort of rubber band assembly to hold the quill up from below, then just pushed it down against the rubber with a pair of long-nose pliers off of the gear and turned it to and fro util it came up in the right spot.

The short answer is - re-insert and check, with the timing pointer on zero, and the #1 piston at TDC.  Best to get everything set correctly, even the cam sprocket.

You could also logic it out, knowing that the distributor turns counterclockwise.
