Can someone verify for me the leading edge of the rotor is at the notch when the car is at Z1? Or should it be at the middle?

I am doing a dist belt replacement, and can't remember how exactly the rotor should sit relative to the notch when at Z1.

thanks,
anthony

 

good good, as is if distributor is already out
on TDC the rotor should be exactly on notch when distributor is bolted
when you introduce the dist. in engine, the axle will tilt clockwise 2 mm and fall on the notch


when dismounting, take a long wire or wire hanger and introduce the small washers in order, because the washers are space shims sometimes, and each distributor has different number of shims.

some pictures of the last one I did

Hi Axel,
Not correct in your pic. Just like Geo said, when the dist. is back inside, both markers need to line up in the center.
Is the motor still at TDC? What I did before I took the dist. out, cranked the crank pulley to the marker on the housing and checked that the dist. fingers are lined up with the markers on their housing. Put it 1. gear and pulled the handbrake, rechecked all markers and pulled the dist. So this way I knew nothing moved when I yanked the dist.
Hope this helps.
Ed

 

I'm sure that you're aware of this, but I figure that you are replacing the rotor as well as it is cracked and is missing the counter balance end, correct?

 

Make sure you're on the correct TDC mark on the balancer. I made the mistake of aligning the TDC mark to the first mark I saw on the balancer not realizing the balancer is marked every 90 degrees. Needless to say, when I tried to fire my car, after changing my distributor belt, my timing was off, way off. It took me a bit of scratching my head and a closer look till I figured it out.

 

Thanks guys. The distributor kinda popped out when I didn't expected it while the motor is not yet at Z1 mark. I simply pushed it back it and rotated the Z1 mark which thankfully was just upcoming up on the crank pulley. I guess when I pushed it back it and it was rotated -2 degrees and that is why the rotor center didn't line up.

In the worst case scenario where someone completely lost the timing, what can you do? I guess there are just 3 possibilities (the 3 Z1 marks) which you can insert in the distributor? Pick one, if engine doesn't run, move onto the next one?

BTW, I will replace the rotor arm. Broke it while trying various methods of removing the distributor.

 

So what did you do? Just pull out the distributor and move onto the next mark until it runs normally?

 

No, it's not that hard. Once you have the balancer at the correct mark, you're either at TDC or 180 degrees out. I was also changing my valve covers so I could see that the valves on #1 were closed so I knew I was at TDC. The little mark you show on the photo is where the rotor should be when the distributor is in place. If it's off you just need to move it a tooth on the distributor gear one way or another. The gears are fairly coarse so it's fairly obvious if your off.

It may feel like it the first time you do this, but it's really not rocket science setting the timing in these things.
