kensval Posted August 13, 2011 Share #1 Posted August 13, 2011 I have a '76 280Z. The (original but no longer bone stock) engine just came back from the rebuilder, but I think they got the oil pump/distributor installation wrong. The rotor does not point to the #1 position on the distributor when the #1 cyl is at TDC, but rather to the next cylinder position in the clockwise direction.In researching how to make this right, however, I'm seeing two different sets of instructions on installing the oil pump which sets where the distributor must go. The 1976 FSM says to line up the marks on the oil pump and the dist drive shaft then pull it out slightly and move the drive shaft one notch counterclockwise. Other sources I've seen on the internet say to just line up the dots on the dist and the oil pump drive shaft and install it that way.So, which is it? It looks to me that perhaps the rebuild shop just lined up the dots, and moving the shaft one notch back would solve the apparent alignment issue.I spent a lot of money getting this engine done, so I want to make sure everything is done right when I finally get to start her up.Thanks in advance...

beermanpete Posted August 13, 2011 Share #2 Posted August 13, 2011 Follow the factory srvice manual instructions. The FSM should take precedent over other sources unless you have absolute faith in the source.Also, ask the engeine rebuilder about this. Perhaps they have a reason/expalanation for the descrepancy. If not, they should correct the problem. Link to comment Share on other sites More sharing options...
Zforce Posted August 13, 2011 Share #3 Posted August 13, 2011 You actually fit the spindle by trial and error till you get the drive tang at the 11:25 position when looking down the dizzy hole with #one at tdc, the dots are for reference since the dizzy will either be right or 180 deg out. If you look at your dizzy you will see the drive tang slot is off center so the dizzy will only fit one way. Link to comment Share on other sites More sharing options...
kensval Posted August 13, 2011 Author Share #4 Posted August 13, 2011 Just to clarify... that's 11:25 when looking down into the dist hole from the induction side of the engine, right? Link to comment Share on other sites More sharing options...
Zforce Posted August 13, 2011 Share #5 Posted August 13, 2011 Your standing on the drivers side looking down the hole. Link to comment Share on other sites More sharing options...
kensval Posted August 14, 2011 Author Share #6 Posted August 14, 2011 That's what I thought, thank you. So then, when the distributor is back in place the rotor should be roughly pointed to the #1 position on the cap? I'm used to Chevy V8s, it works different for them.

Zforce Posted August 14, 2011 Share #7 Posted August 14, 2011 Yeah at about 11:00, if its point down your 180 deg out. Link to comment Share on other sites More sharing options...
