One of my part suppliers shipped a part to me by mistake, any idea what it is and what it would be used on? Part tag says 0ba-6763-a.

 

Draft tube for 6 cyl?

 

MMM, probably not, doesn't look like any of the draft tubes I've seen on the 226's car or truck.

But it could be the refill hole pipe for the elusive steam wrench.

The base part number 6763 is for the pipe - engine oil filler. I don't have this number in my Canadian parts books, as we only had the 239 V8 which was 8BA 6763.

 

Like said the 6763 is an oil fill tube. A 0BA 6763 is the tube for a 226, 254, and 239 engine. But the -a suffix isn't listed in any of my old paper chassis catalogs or OSI catalogs. The 0BA 6763 was a number change from 7HA 6763. If Bill sees this can he add insight on the impact of the suffix in situations like this? Stu

 

Probably an angled pipe to clear the air cleaner on a COE, or auxiliary equipment like an air compressor on the big 'uns. Note there is nothing to bolt the brace to on regular 8BA's.

 

The 0BA 6763 is listed as applying to the whole range of models that could be fitted with these engines. But I'm still uncomfortable assuming that 0BA 6763 is the same as 0BA 6763-A. Stu

 

I could see how the same filler could be used on a 226 and a flat V8, even tho the 226's is shown as having a bend in it. But the bend is nowhere near as much as this piece, so the A must refer to a specific application on the V8.

 

This looks like it, a COE with V8. You can make out the brace to the air cleaner. Almost looks like you put a regular V8 filler into the top of it?

edit, nope; found a better pic of the COE filler

 

That's what's frustrating. I've got every original print chassis catalog edition 1950 to 1955 plus the reprint 1956, and each of the OSI catalogs covering the era, but nothing with that suffix. Agree that the suffix is generally the key to the application. Stu

 

There's no A after 6763 .. It's listed in the 1948/56 Ford truck, 1949/59 Ford car, 1953 Ford/Merc Canadian truck parts catalogs as:

0BA-6763 .. Engine Oil Filler Pipe / Obsolete

1948/51 F1/F6 226 I-6 / 1948/53 F1/F100/F6/F600 239 V8 / 1950/53 F6/F600 254 I-6 / 1953 C500/600 239 V8.

1949/51 Ford Passenger Car 226 I-6 / 1949/53 Ford Passenger Cars 239 V8.

My O-S-I catalogs state: 0BA-6763 = NR (Not Replaced) aka Obsolete

 

Okay Bill, our books agree. But short of questioning 3twinridges' ability to read the number there is a "- a" suffix on the part. I trust Ross' hands on knowledge of these engines, so the thing must be an oddball fit to some unknown application.

So back to my above question. Is there some method to Ford's madness when assigning a suffix? We know there is with the assignment of a prefix, so I'd assume a formula existed for the suffix as well.

Maybe this simply gets added to the phantom number category. Like my obsession with the 7RC 1015 mystery wheel. Stu

 

0ba-6763-a was on the picking slip and you can see the -a if you zoom in on the picture. But when I did that it kinda looked like 0ba-6753-a, does that sound like a draft tube part number?

JB

 

The 6753 grouping is for an "oil level indicator boss gasket". And nothing with that prefix or suffix. Stu

 

It could be a military, industrial, or export-only part, I assume those don't show up in the usual books. Lots of flatheads in airport tugs, air compressors, driving water pumps, tractors, etc. The bead on this part pretty definitely points to the fill pipe, a measurement of diameter would confirm. JB, can you stick it in a V8 manifold and post a pic? Doesn't need to be fully seated, I'd just be curious to see the angle. Does it have a dimple at the straight end to align a breather cap?
