Happens all of the time to everyone. The slot in the oil pump shaft is not aligned with the distributor. Take the distributor out and note the orientation of the lug in the bottom gear. With a long screwdriver or paint stick or similar tool, turn the pump shaft until the lug will align with the slot when headed down in the correct position. It may take a couple of tries. If it doesn't work, set the distributor in and crank the motor over and you will see it drop. Now find TDC again and verify your rotor is pointing to number one.

The slot on your oil pump drive gear got out of alignment. Gat a long, large flat blade screwdriver and try turning the gear a bit in either direction. Then put the distributor back in. Repeat as needed until it goes all the way in.

Most likely the oil pump drive needs to be lined up with the cross pin in the bottom of the distributor. I would probably just click the key slightly to crank the engine a bit. But this is probably the more accepted way to do it:

I would also email Lars at V8fastcars@MSN.com and request his distributor installation, how to set timing and vacuum advance papers.

Your distributor is not engaging in the oil pump drive shaft slot. Look in the bottom of the distributor gear. See that tang? it must engage in a slot on the drive shaft slot. You can see the slot/shaft with a good light looking into the distributor hole.

Here is something to try.

With a paint stir stick or long screwdriver, make the drive shaft slot align exactly front/back 0*/180*.

Put engine at TDC #1 firing position.

See that dimple on the distributor gear? Align it so it is pointed at exactly 180* Towards front of engine.

if you drop the dizzy straight down, as the dizzy gear catches the cam gear, it should rotate the dizzy shaft into alignment with the drive shaft slot.

You can also always drop the dizzy in to where ever you want the rotor to point and rotate the engine by hand and the dizzy will eventually align with the drive shaft and drop the rest of the way down.

It sounds like the distributor male end on the very bottom of the distributor is not aligning/mating up with the oil pump shaft female end in the engine..

Could you share some info on engine type/size? (I’m assuming s/b chevy?) what brand/make of oil pump, intake manifold & distributor?


Thanks

Did anybody mention the oil pump shaft? :-)

If you are so inclined, you can lift the distributor up just enough to disengage the lower gear and walk it one tooth clockwise and drop it back down until it engages the pump shaft. When that happens keep lifting and walking one tooth at a time and drop it down each time and the oil pump will follow. Repeat this until you come back around to the correct #1 position, if you miss the correct position just go around again until you are good.

Once you get the hang or it you will never do it any other way.

tbarb's suggestion works, takes a little time, but works. If you are impatient, hit the key and tap the motor back around to TDC. The distributor will drop in. Just make sure you are on the compression stroke of #1 when you are done.

3/4" socket (if a big block), on the damper bolt and 18" breaker bar will turn the engine over easily if no plugs in the heads.

If it’s not dropping in then something mechanical must be causing a hang up? Soooo, could you please share some info on parts being used have any of these parts been together/married in this engine before ?
New parts (aluminum dist. VS O.E. Cast Iron) could you share some pics of dist. Gear & shaft drive, is that a replacement gear on the distributor?

P/m me your # I can call you if that helps? ( 6:00PM - 7:00PM) I’ll be recovering from grandkids, will appreciate Car talk:-)…

Is the harmonic balancer retained with a bolt or is it just pressed on? If it's bolted how about removing the spark plugs and turning it over with longer ratchet?

I set my engine to TDC, put the distributor in with the rotor facing the #1 cylinder then bumped the starter until the distributor dropped in. You may need someone on the outside putting downward pressure on the distributor while you bumped the starter. It's really easy.

Take the oil pan off, take the oil pump off, the shaft will come out with the oil pump.
