Distributor install issues lyb

[B-ster]

Ok. So I removed the plug in the outside of the block so I can access the oil galley plug that feeds oil to the distributor gear. I tried tightening it so the gear will clear it but it was bottomed out so I removed it. I talked to my mechanic and he told me that if it's too far out that I can grind the back of it down making it go further into the block giving me clearance to install the distributor. I ground about 1/4" off the back, leaving 1/4" to screw in. That plug now won't go in but two turns and stops abruptly. I tried using a tap but it goes too far in before starting to clean up the threads and hits the lifter. So now I have a 1/4" plug still sticking out interfering with the distributor gear. i don't know if this was the original plug or not, nor do I know if maybe it's supposed to be tapered so it'll go in further. I could bring off the front of it, leaving enough of the Allen head to still screw it in and use thread lock. But it just seems like this isn't the right plug . It does have a hole in it with a star pattern so it looks right
If anyone knows the dimensions of the oil galley plug for a lyb 54, and what I need to do to get this problem resolved, please let me know. it's been one thing after another. Thanks

That plug is TAPERED THREAD. If you grind the end it is still going to only go into the hole so far. If that is the only plug of that size you have, the hole needs to be deepened with the correct NPT TAP so as to allow it to go in further. Make sure it does not contact the tappet in the tappet bore.

When you had the plug out, did it have an orifice to pass oil?

Take the plug and try to ID it by the sizing chart. I found listing for plugs in the MPC but the descriptions are not concise.

Can you take a photo of and post? Did the machine shop say anything about the plug?

Below are some charts to ID NPT SIZES -

It has a star shaped hole in the middle of it. I figured if I had removed the back end of the plug it would still go in the same amount as the taper would allow it to. I don't suppose there's a place to look up the part number. I know you did put on some info. That -4 looks like the right size. There's not much info in the manual, actually none to refer to. That's why I'm asking on here. I know there's someone that has removed or installed one and can let me know what it is. I really believe it has to go in until it's flush. And there's only maybe four threads in there

Did the machine shop assemble the engine? You say the LOM DIST was difficult to remove?

[B-ster]

My mechanic said he put the plug all the way in and he didn't think about the gear clearance. He said he has shorter ones so I don't know if this is the original one. Here's a few pics

Where?

Who actually assembled the engine? Was the fitting removed to tank the block? If he installed the DIST, why didn't he mentioned having trouble installing?

[B-ster]

Yes, he removed it to tank the block and he didn't install the distributor. I did. I ground the front of the plug and installed it. The distributor went in no problem.

OK, let's try this again. The old DIST came out easily during tear-down? The re-builder did not re-install the OEM LOAD-O-MATIC DIST but you attempted to install a 1960 FYB DIST with the LYB DIST GEAR and this gear interferes with the fitting? How badly was the FYB DIST SHAFT damaged when trying to take the gear off?

CORRECTION -

You removed the LYB DIST GEAR and put it on the FYB DIST.

Are both of the DIST GEARS the same dia.?

Where are the photos of the fitting?

[B-ster]

Yes, the load I matic dist was very difficult removing. I took it out and my mechanic did not have a distributor to install. I found the 60 fyb distributor and swapped gears. The bottom of the shaft was a little mushroomed that's why another shop swapped gears. The gears are the same diameter. Using sandpaper and a drill I took the mushroom off. All is good with it now

[KULTULZ]

All is good with it now

Are you saying the DIST slides in now?

[B-ster]

Yes. It slides in. I posted that a few posts ago.

If anyone needs the PN of this plug in a future SEARCH, it is FORD STANDARD PN 87837-S.

Below is the PART DESCRIPTION in the 1952-54 LINC CHASSIS PARTS CATALOG -

I found the intermediate shaft is a little bit too long. There's no problem cutting a half inch off the bottom of it is there?

Are you asking about part of the distributor shaft that engages the oil pump drive shaft???

[B-ster]

It's the shaft under the distributor shaft and goes into the oil pump

[dmsfrr]

Not being sure which one you have (similar to the hex shaped shaft in a '55+ Y-block?) my opinion would be to trim it as little as possible.
Just enough so it isn't too tight.
Having it come undone while running & driving would of course be very bad. (but you knew that)
Measure 3 or 4 times, cut once.

Here we go -

Can you give me the DIST. ID NO. off the DUAL ADVANCE DIST you are planning to use?

- DEARBORN - WE HAVE A PROBLEM -

I was wondering what you meant about an intermediate shaft. Now I know.

The 1952-1954 LYB used a tang-drive DIST as did the 1954 FYB 239CI.

To use a later DUAL ADVANCE DIST (LINC/MERC LYB) you are going to have to change the oil pump to a later hex drive style.

[B-ster]

I have changed them all out and have the hex drive shaft. It's too long and I was looking for advice on which end is better to cut off and technique. Where's that sliding washer supposed to be located?

[KULTULZ]

How am I going to get myself out of this one ...

The oil pump on your engine will not accept the hex drive shaft. You will most likely have to replace the oil pump with a later model (1957/ ) to use the later DUAL ADVANCE DIST and drive.
