440 Finals

[whiteclipse16]

Hey guys, may have ran into a slight problem when working on the 440 last night.
I was looking at pulling the main axle out of the final so I could replace bearings and such when I noticed what I had didn't exactly match what was in my parts book. I checked the part number on the final and it didn't match what was in the book.
Long story short, some years ago my grandfather bought some spare parts for his 440 (tranny, steering clutch housings, and finals). From what I've gathered I think these parts were off a 58 model.
The number off the one which I think is a 58 is T19407.
The number off the other two finals I have is T10004T which matches what's in my book.
I put the steering clutch housing up to the final and the holes all match up.
The major difference I noticed is the casting of the two holes to the left and right of the axle shaft. I'm not sure what that parts bolts to so I don't know if it will be a problem or not.

Do you guys know if I'll be ok using this final?

The T19407 is very late 440, after 456,802 which would be a 1960. The other ones are from below that serial number.
The late final used different axle, bull gear if gas crawler, sprocket, bottom cover, pinion cover, and a few other differences.
You should check your serial number to see which one you should have.

That doesn't sound very good.
The serial tag for my dozer is gone. All I know is that is a 59 from the descriptions given on here (Diesel, large tranny, throttle lever in corner not center, etc.)
What would my options be?
Is it possible to use this 1960 final on one side and the 1959 final on the other?
Can I take the gear(55 tooth) and axle shaft, etc out of the bad 59 final and put in the 60 final?

Hey Lavoy,
I'm going to have to use these late 1960 Finals.
How different is the sprocket I will need. (Bolt pattern, amount of offset/dish, etc.)
Also, is the pressure plate different or anything else with the clutches.
Any info you can give me would be great.
Thanks

The 1960 model year started at 453,873, the large finals started at 456,802, center throttle started at 458,704, last serial number built is 461,929. This means they built almost 5,000 1960 440's without the center throttle, and about 3000 with, so not all 1960 model year machines have center throttle.
The large final crawlers use the 1010 sprocket, gas used a 56 tooth bull gear, but diesel still used the same 55 tooth as all diesels, and gassers prior to 444,128. ALL 440 sprockets will fit in ALL 440 finals, just keep your tooth counts the same side to side. Some bearings, the axle, bottom cover, axle quill and such are different on the late finals, and you will have to use them.
Clutches are the same, or at least will interchange.
If you don't have a set of late sprockets to put on the crawler, you are looking at some additional expense there.

Thanks for the good info. I suppose mine could be a 59 or early 60 because the original finals on it are the lighter finals.

So these late 60 finals I am going to use have a 56 tooth bull gear, meaning they were off a gasser. Since mine is a diesel will they be ok to use. My gearing will be a little different possibly but that doesn't really concern me, what concerns me is if the gears are built heavy enough. I don't think there would be a difference though.

Correct me if I'm wrong but it sounds like I can use the sprockets I have ( off the lighter finals) on these heavier finals since I'm going to use both heavier finals.

Yes, the gears should work, you will be geared down about 10%.
No, the sprockets will not work.
