How to remove distributor / oil pump drive gear on a Magnum / LA and Sync distributor
I put the darn thing in, but decided I wanted to take it out to check oil pressure with a mechanical gauge as I primed it before I tried to start the engine. I could not figure out how to get it back out. Here is what I ended up doing and it worked very well multiple times (had to sync the distributor).
Take a strong, thin wire and work it down under the gear. I find it easiest to stand on the passenger side and work it into the driver side of the gear. Once you get it under there, with a large screwdriver in the slot of the drive shaft, work the gear back and forth as you pull up on the wire. You may need to wrap the wire around something to let you pull harder. Use the screwdriver to give a little counter-pressure so the gear doesn't come flying out.
Also since this is a new engine, I had to sync the distributor.
To do this, bring #1 cylinder to exactly Top Dead Center on compression (pull #1 spark plug and turn the engine over clockwise with your finger over the hole, if air is blowing out, you are on compression, stop turning the engine over once you get to 0 on the timing indicator).
Take your distributor hold down and note the tab in the center that fits into the slot on the distributor. This limits the amount of rotational adjustment the distributor has. This will give you a good idea of where your distributor will need to sit.
With the distributor in this orientation make a note of the direction of the distributor drive blade when you line the rotor up with the No. 1 Cyl mark. This is where the gear will have to end up.
Slide the gear into the bushing and engage the oil pump drive shaft into the oil pump by rotating it back and forth a bit. Now advance the gear clockwise about 45deg and engage the gears.
Test fit the distributor. Line the drive into the slot and rotate the housing so the rotor points to the No. 1 Cyl mark exactly. If you can do this with the distributor hold down in place then you are good. Tighten it up. If not, you need to pull the gear back out and move it the proper direction. The rotor should be pointing to the front passenger side of the engine.
