289 crankshaft ID

[Jeff T.]

I had this thought when I was digging a V8 crank out of storage. How would I tell a 259 crank from a 289? What would one do if they were at a swap meet amid a mass of unmarked cranks with visions of R series clones dancing in their heads. Are there casting numbers, quick dimension checks (ie length of throw from crank center to rod journal center)or something I have not considered.

Just wondering

David;
What about the long snout full-flow 289 crank casting: 1556444 part number 1558030? There are only 2, 289 crank casting numbers, early: '56 to 'early '62, and late: '62-'64 and mine is the late one, so one of yours is wrong! [:0]

Everyone: keep in mind all 1953 & on Stude. chassis part #'s and casting #'s start with 53: early and 15: late, AND it is quite hard to read. The casting # is raised numbers on the second counterweight (number one rod journal-rear counterweight) cast on a curved surface so the first or last # may be unreadable or close to it! [:0]

Sorry, I had to double post to update this because I think my system (could be the website!)will not let me log on to update prior posts, only logs on to NEW posts! And I cannot delete the old one until I figure out what setting is wrong!

OH! I see you got them from Bob Johnstone's site! No offence, but his typist has a lot of typos! Both 289 crank numbers are wrong! He has a 536 # with 7 digets, has to be 6, and a 537 # with a "?", so neither are any good! [:0]

There seems to be some confusion about crank casting numbers and I haven't been able to decipher all that's been printed here. So that I and others don't misinform others, can we find what actually are correct numbers?

Here is what I have for crank casting numbers and would appreciate anyone knowing to correct any I have wrong: (Hope I don't have any typos here)
*****************************************************************
1547105
1550774
189986 These are all for 169" from '43-'54 and '59-'64
199966
521525
521526
908292
******************************************************************
176254
186433
534521
534231 These are all 185" from '55-'58
534251
534254
535377
*******************************************************************
523135 These are 226" from '47'53
523774
*******************************************************************
523168 This one is 245" from '49-'59
*******************************************************************
526831
526832 These are all 232" and 259"
530081
536452 (This one, 536452, is one listed elsewhere as a 289 but)
1556997 also notice the number has an extra "6" [5366452])
*******************************************************************
533439 This one is 224"
*******************************************************************
180590
526956 These are all 289" and 304.5"

Hi,
I get most of the info on my site from this and other Stude forums. Nothing is added or deleted. Barring any challenge to the data, it gets posted.
The info passed in this thread, will now replace the old....

Ted; do you know where these (2) 289 Crank casting numbers came from: 180590 and 526956? They date back to pre 1956, especially the first one to the 1920's. So I have to wonder if they are correct. I have never seen a 289 or any crank with those numbers. Then Bob J. can add the correct info to his website.

I have physically seen the last two, so I know they are correct. It seems that is the only way to know for sure.
Thanks, Rich.

P.S. I have seen lots of 1556444, and I know those are the only ones that could be Avanti or 304.5 because they are the long nose cranks, part number 1558030 for all late '62 to '64 full-flow 289 & 304 engines.

After a LOT of searching I finally found where I got the two numbers you asked about (180590 and 526956).

They are in a 1999 Clevite Engine Bearing Catalog with the following numbers 2-200-99 and states "supersedes issue dated 1996" stating these are crank forging numbers.

Here is something even more interesting: It states these two cranks are for 1964 304" engines with 3.656" bore and 3.625" stroke.

Doesn't mean the book is right but that's where I found them.

The Avanti Part book shows a different part number for the R 3 and R 4 cranks.

Interesting, usually the casting numbers follow along pretty much with the same number group used the year when their corresponding part numbers were created. I wonder if there was a 1929 Stude. straight 8, with 289 cu. in.? LOL

Oh well, at least any of us can verify that 537424 and 1556444 are good early and late 289 crank casting numbers. [^]

Thanks very much Ted, for doing the research for us. We can go with that until proven otherwise!

The only other one I see, that stands out as being questionable is the 169 small 6 number: 908292, the "9" is very unlikely.

Holy Thread Revival! (search is your friend.....)

I did a search for the crankshaft casting numbers that I have on a crank in storage. I was TOLD that what I have received is a 289 crank out of a 1955 Studebaker (no idea what model or year for sure) so I thought I would check the casting number.

I can ONLY see the numbers 53742 on my crank (see attached pics) and therefore I am ASSUMING it is actually a 537424 based on the comment above by StudeRich. If anyone can confirm that or if the last digit is somewhere else on the crank, I will take another look.

Also, is this a long snout or short snout? If I want to install this in a 1963 259 block, what provisions must I make? Harmonic Balancer / pulleys / generator brackets? How does the 259 crank compare on the snout / timing gears to the 289 crank?

Thanks!

If you have a 259 crankshaft and a 289 crankshaft next to each other, the 289 crank has noticeably larger counterweights. Good way to spot one if you are looking at a bunch of crankshafts together.

The only crank numbers I have that start with 537 is the 289 with the number being 537424. Hope this helps.

Thanks Ted!

That what I was guessing, based on looking at every number in the list and the ONLY one starting with 537 being the 537424.

Do I need to change the harmonic balancer or look into having a different offset on the pulleys? Or are the snouts the same length?

You have the short nosed shaft. Yours should measure abut 2.8" and the long is about 3.3" if my memory is correct. As long as you are not using extra things on the nose of the crank (like supercharger pulley, AC, etc.) you should be fine.
