how to get the dizzy that last 1/4" down

[Asa]

doing the DSII swap now, and i need to know how to get the dizzy seated completely, it's right at that last 1/4" and won't go down

i tried puttin a piece of wood between the dizzy and it and tappin it home, i just dug a hole into the wood
tried tappin the base
i don't get it...

Evan, are you sure that the bottom of the dizzy shaft is lining up with the oil pump properly?

 

[Asa]

pretty sure

although i can pull it and check to make sure

Evan,

I don't know what year block etc. but could it be the base of the dizzy is larger than the hole in the block?

Has this dizzy been in this engine before? or is it a different one?

 

[Asa]

the dizzy fits, it's just that last 1/4 that doesn't

and it's brand new

They can be a little tight. Check with the oil pump shaft pulled out (you may need extra long-nosed electrician's pliers for this). If it still binds but you can feel the gears meshing OK, then an even sanding/scraping of the alloy housing may be needed. Mask up everything to avoid grit hanging up in the assembly.

I use moly grease on the gear when assembling the dizzy to cam. There may be also a thin paper gasket to stop oil seepage under the base when clamped. The gallery pressure is present here, so it's significant.

See how you go with this tack.

Same thing happened to me, after a lot of cursing, turns out all it took was to "wiggle" the rotor and housing util it seats, be patient my friend, cuz it sure takes a while

Get a bigger hammer :smash:

Seriously It sounds like the drive shaft for the oil pump is not lined up. Try taking the distributor back out and give the oil pump shaft a slight turn. Then try the distributor again.

Evan,

Numerous times I've run into this when putting a DII into an older block. I've solved it by taking my Dremmel with a sanding roll to the aluminum body of the distributor where it fits in the bore. 5 or 6 times around the distributor (lightly) with an 80 grit roll should do the trick and let it drop in with a little force. Be sure to hit it with some brake parts cleaner to knock off the shavings/dust before assembling it.

Evan, I just installed my Duraspark last night, and I agree with the posts that suggested that you turn the oil pump drive shaft ever so slightly. You may have to do this several times before it drops in, but it will!

It's probably the oil pump shaft. If you hold the dist down and bump the starter it should drop on down. Then bump the engine around two revolutions to TDC and time it.

I've always done similar to Stubby. But I use a ratchet with a socket on the balancer bolt, I dont like to use the starter when assembling. It just doesnt seem to stop when I want it too.

Note that the oil pump shaft tilts slightly to the driver's side. (When the distributor is removed) Jack up the driver's side of the car so that the shaft moves back to its centerline. The distributor will drop in.
Well, its worked for me. Good luck.

I just had the dizzy out on my car. All I did to replace it was to move the balancer a touch and applied a little pressure on the the dizzy, it fell right in after a few tries. Good Luck
