I would remove the oil pan and count teeth.
Here is the Deere on-line Parts catalog.
https://partscatalog.deere.com/jdrc/sid ... Id/2308523
It looks like there is a SN split……with the earlier have 55 teeth and the later version has 56 teeth.
Good luck

Re: JD 440 ICD Veers to the left
Sounds like it is time to count the number of teeth on the final drive gears. I suspect you may have differing numbers from side to side given the info above

Re: Steering issue
Excellent detective work. Not trying to be “that guy”, but I was looking at your crawler and I believe your left track chain/pads are on backwards. Just double check, it is kinda hard to see accurately in the pic.

Re: Injection pump timing
There will be a hole in the flywheel. Not through the flywheel, but it is deep enough that only about 3/8” of the special bolt will be sticking out of the flywheel case. The key to this whole timing thing is to have #1 cylinder on TDC. So both rockers will be loose because of valve lash. The two mar...

Re: 450 Injection Pump Issues
Yes, those are “mouse turds.” Time for an upgrade to a one piece governor ring.

Re: JD 350 fuel injector timing
Hey Jim, he is working on a 3 cylinder, 350. I don’t believe a 4 cylinder 350 was built.

Re: old 450 won't move
If there is water/stuff/mud in the steering clutch housing, this will cause the steering clutches to slip. Your machine is a dry steering clutch housing machine. Any contamination will disable the clutches. So if water was over both housings, I would say you are going to need to tear down, clean out...

Re: 455G How to get it to move?
450G’s have a bolt with a jam nut on each side of the clutch housing. To roll them, you loosen the jam nut and screw the bolt out? Or in? Now I can’t remember to let the brakes completely off. Then it should roll. I think the 455’s might be the same but can’t be certain as I have not been around one...

Re: diesel fuel leaking into engine oil, JD450b
If the internal components of the lift pump have failed and allowed fuel to leak into the oil sump(which is a fairly common failure) you either replace it or completely bypass it. If you still have fuel running through it, the fuel will continue to leak into the oil. Have you isolated the pump and t...

Re: Blade skid pad shoes?
Good morning. Most Deere dozers have a float function with the blade and valve. You may want to review the operator’s manual. This function would fill your need IMHO.

Re: 450B Transmission and Engine Swap
Everyone is different. Here is the path for me. Keep this crawler, find a crawler with loader (same build/model). Use the free crawler as a donor, not if needed but when needed for breakdowns on the track loader which you want. Getting harder and harder to find parts and some are made out of unobtai...

Good morning, I was unable to find the OEM numbers. But I have listed the exact link to the one I have in my 450c. Works great, sounds like a Toyota when cranking, but I’m okay with that. https://www.ebay.com/itm/330649773100?hash=item4cfc43242c:g:n7sAAOSw6jJcF00h&amdata=enc%3AAQAIAAAA8GJHKfwoOs56KN...

Re: JD350 - PTO
Welcome to the site, I really like the pics. What a find, nice OEM three point with center link. The sticker is a “generic “ sticker attached to almost all of our late model yellow machines. The cover is where a winch drive or the pto shaft would go. There is definitely not room for a pto under that...

Re: 450 in pieces
Check the clutch housing. Like mouse nest, debris, corrosion etc. check the drain hole in the bottom of the clutch housing. Is it free or plugged?
