Late 440ICD finals

[BKahler]

I'm sure this has probably been discussed before but it never registered with me.

Recently it came to my attention that the later 440 crawlers (at least the diesel versions) used the same finals as were being installed in the 1010 crawlers. What makes it more confusing is these finals are not shown in the diesel version of the 440ICD parts or service manuals and they are not shown in the gas versions either. What this tells me is for the later diesel 440 crawlers in order to service the machine properly a person will need copies of the 1010 spare parts manual AND the 1010 service manual.

What I would like to know are there any other differences or omissions in the 440 manuals that would require the use of 1010 manuals to resolve?

Thanks,

Brad

Do you know at what 440 serial number they started using the 1010 finals?

I wish I did. I haven't pulled mine to see for sure they are the same as the 1010 but someone else I know for a fact has 1010 finals. My serial number is real late in the series so I'm making the assumption that I have 1010 finals.

Sure is interesting how John Deere made changes like this. My diesel manual is dated January 1966 so you would have thought they would have incorporated all of the changes into the manual by that time.

The 440 got the big finals at 456,802, no distinction between gas and diesel as far as the case. Only difference is the bull and pinion gears. Late gas used 56 and 13, diesel used 55 and 14, same as all other gassers prior to that, all 430s, and all 420's after 125,001. The case is the same as early 1010, but the gears are not.

Lavoy,

I find it interesting that John Deere never bothered to update the diesel crawler parts manual like the did the gas parts manual for the 440s. The parts book for the IC that I have reflects what you've said about the serial number change over. The good news for me is my crawler is later than the change date so I can hope that the 13/56 combination is in mine.

Do you know of any other changes that aren't reflected in the manuals for the 440s?

Thanks!

Not sure what you mean by updating the manual? The diesel manual shows the serial number break and all the corresponding parts. Maybe you have an old manual, what is the revision date?
If you have a diesel, then you have the 55 and 14 tooth combination, diesels never had the late gas gear set.

I think I've been confusing the issue. For some reason I got gear changes stuck in my head when in reality it's the the flanged axle shaft that was the issue. And you are correct the diesel parts manual shows the shaft change.

Don't know why I became fixated on the gears

The problem with the parts manuals is they don't show the differences in the axle shafts, just the part number changes. I believe the same goes for the service manuals.

By the way my ICD parts manual is PC-609 dated Jan/66. So I would assume its the latest revision.

My 440 crawler service manual SM-2023 dated 2/63. Which I would hope is the last version. It does look like you need the 1010 service manual to see the differences in the axle shafts.

Sorry about the confusion!
