Distributor Replacement

Distributor Replacement

Here I have some pictures of the replacement of the distributor.  This is the new distributor from Mopar Performance (via Jegs).

Finished 

Here is the distributor from Mopar Performance (via Jegs) with the performance advance curve.  I polished the distributor and clear coated it.  You can read about that entire process on this page.

Before

This is the condition of the distributor that is in the car now.  I installed this one back in 2001.  I did not do anything to it other than put it in the car and set the timing.  The corrosion on the part is horrible.  I did not realize just how long ago I installed that unit.

Time does fly...

 
Old Distributor

This is the old distributor removed from the car.  You can see the corrosion on the body of the unit.

Old Distributor again

This is another shot of the distributor from the other side.  I believe that the polishing and clear coating that I have done on the new distributor should prevent this from happening in the near future.

Cam Gear

I did want to point out that this would be an excellent time to inspect the distributor drive gear on the camshaft and the distributor shaft for wear.

You can even see a couple lobes on the cam.  Though not a great indication of the condition of all the lobes on the camshaft, at least you can get a small glimpse of the condition of the first couple lobes.

Cam Gear

This is another shot of the cam gear and the distributor / oil pump drive gear and shaft.  Notice on the 440, you can only insert the distributor two ways.  The end of the shaft on the distributor itself looks a little like a flat blade screwdriver.  So, in this case (since we have not removed the distributor drive shaft) you can either get it right or 180 degrees out.

Cam Gear again

As long as you pay attention to the orientation of how the distributor came out (and you removed the cap to be able to see the position of the rotor), you should be able to at least get the rotor orientation right.

The rest is just a matter of spinning the distributor housing to get the timing set.

Distributor Base Gasket

This is the distributor base gasket.  It is a thin all metal gasket.  There is a rubber "O" ring on the distributor itself, but this goes in between the distributor and the engine block.  I took this shot with the gasket in my hand so you could get an idea of the size of the gasket.

Distributor Base Gasket

This is a little cleaner shot of the gasket.  I just wiped it down with carb cleaner and put it back in.  You can not use a gasket sealer on this ring since the distributor still needs to spin to adjust the timing.  And given where this goes, I would not want to take a chance of getting old gasket sealer in the engine.

Wiring

I am fairly certain that the Mopar purists are out there screaming but I prefer to solder the connection of these wires and use shrink tube over them to seal them.  I have had trouble in the past with the connectors that come on the distributor and I would rather take the extra few minutes to solder the connection together.  ***NOTE:  The reason that the wires are different colors is the MSD ignition that I put in years ago has a different color scheme on the wires.

Done

This is the distributor installed.  I received a new cap and rotor with this distributor so I installed them as well.  The other distributor may have had all of 1000 miles on it since 2001 but the brown cap is fine.  The blue cap was sticking out like a "sore thumb" so the brown cap is actually a little more subtle.

If you have questions, please feel free to e-mail me.  I will do what I can to help.
