White 2-105 rear ends? How strong?

Are they the same as a Oliver 1850? 1950? What about a White 2-120 or 2-140? Same rear end as 2-105? I'm thinking of doing the 5.9 Cummins conversion. We have fair knowledge of the Oliver brand but don't know much of the White nomenclature. Thanks for your time. Eric
 
The 2-85 and 2-105 both used the 1855 rear end to start out. I think the later 105s had a beefier ring gear and better brakes.
 
Are you real, real sure on that? The 2-105's I have looked at had 1950T rear ends. I need to look in my book and that is not going to happen till probably Thursday. J.
 
Thanks for replying. I have read that the 1800 series is a bit weak in the rear end. There were some problems that Oliver didn't have in the other models? Is the 2-105 or 1855 rear end ok? Did they get them figured out by then, with the later models? What about the White 2-85 is it also an 1855?
 
Not positive,no. I'd just been told over the years that they started out with the 85s and 105s being the same tractor except the turbo,but the 105s were beefed up later in production. If you say otherwise,I'll believe you.
 
Not to argue,because I really don't care one way or another,but thinking about it,if the 105s had a 19- anything rearend,they would have to have been a 1955 wouldn't they? Didn't the 1950 and 1950T have the internal open center pump and the 1855 and 1955 have the closed center pump mounted on the side?
 
You guys obviously know more about these Whites and Oliver's then I do. I have driven most of the Oliver's and completely rebuilt a 77, but stepping up to a White tractor for a rebuild, or restoration is going to challenge us. I have read a lot on here about putting the Cummins in a White. Seems like something we could handle, with the help of some local people. I'm just trying to learn about the difference in the different White Tractors. Seems one can find 2-105's for sale that need work. You can't find a 2-140 less than $10 or $20k.

Anyway if the 2-105 came with any 1900 series rear end I would be happy. Or if anyone has knowledge of what was the weak spot of the 1800 rears, and were they stronger by the time White was using them I would be interested. Thanks for your time!
 
The 140 was pretty much a 2-135 with a Cummins instead of a Hercules,so doing a conversion wouldn't even be an option on a 140. They already had a Cummins. You'd just be replacing the engine with what it already had.
 
2-105's were pretty much 1855 rear ends. 2 disc brakes, no pinion snubber, smaller bull gear/axle splines than a 19, ect. Still a good tough rear end.
 
Just what I thought. They upgraded to 5 disc brakes and larger pinion later in production didn't they?
 
If you check the parts breakdown on agco parts books . com you will see the rear end on a 2-105 and 1955 are the same , differential supports and ring gear support bearing are in both. The 2-105 went to two brake disc on a side like the 1855s but the rest was a 1955 rear end .The 110s went back to three brake disc per side otherwise the same . The 120 and 140 are totally different from the early whites they are heavier , have wet brakes , a differential lock ,and a better hydraulic system. Plus they came out with a5.9 cummins in them.
 
If you bought a 105 why wouldn't you just keep the Perkins? There's nothing wrong with a 354 in my opinion. Seems to me it would be a lot easier than swapping engines.
 
Reasons are many. Lot of 5.9 knowledge around here in my neck of the woods. Two local diesel shops specialize in the 5.9. Even my sons FFA teacher for that matter. Also I want a project tractor. Considering an 880 or 770 but the idea of a White kinda got to me. Don't see as many around here. Those 140's sure are desirable.
 
must be pretty tough, my 2-105 has never had any drive line work except clutches , and a seal in the over under once, bought new in February of 75, and it was used for heavy work For several years. Not a clue on the hours, too many hour meters replaced, but would est 15,000, 4 th set of rear tires, including duals looking good , buts it's retired to a loader- blade tractor on a grain farm, but still gets used some, maybe even mowing road banks with a 15 ft rotary mower. Been a tough sucker, several sets of rods and mains bearings, one complete major overhaul, that all, still doesn't use much oil if worked hard, mowing hay or other lite work, maybe a 1/2 qt daily. 125 hp since new.
