north-central Indiana west of Fulton | Until someone with more knowledge than me replies....the 50's had Perkins I think and the 55's had Waukasha, which I guess was not good. The 1950T had a Detroit diesel. |

|
Eastern North Carolina | 1950T had the 6 cylinder turbo Waukesha 310, the 1950 had the 4-53 Detroit. |

Nebraska, The land of corn and cattle | The 55 series was an upgrade of the 50 series.
Quick rundown:
The 50 series mostly had 2 speed hydropowers except for the later ones got 3 speeds, the whole hydraulics system was changed from the 50 to the 55 series, depends on who you ask which was better, the 50 series could only support 2 remotes where the 55s could be stacked up to 4, the 55 series has more hydraulic power, but the lines are somewhat of a nightmare, after so many years the steel lines like to crack. 55s will have a lights in the grill, where the 50s wont. Other than that, cant think of much for major differences.
1850 had perkins 1855 was a turbod waukasha,
1950T was also a turbod waukasha, the 1950 had a 4-53 detroit
1955 had more power than the 1855, just more fuel basically, I think there is some differences in the rearend, like some heavier bearings or more bearings IIRC.
If I was to build the perfect tractor, itd be a 1850 Perkins, with a 3 speed, mated to a 1955 rearend and hydraulics. |

North Central Illinois | The 1850 was the only Oliver with a Perkins. The 1755, 1855, 1955, and the 1950T were all Waukesha 310's. 1755 was non turbo, 1855 was turbo with no oil cooler and 1955 was turbo with oil cooler. The 310's had issues with wrist pins and rod bolts. Once they got this figured out and got the engines properly updated they were a really good motor. Very smooth and good on fuel. I can't imagine there are many 310's left running that haven't been updated. Those that were not updated tended to ventilate the block. I would take a properly built 310 over the Perkins anyday. |

Nebraska, The land of corn and cattle | I believe the 1855s got the oil cooler update also. I would have to disagree on the 310 over the Perkins, we have a properly built turbo 310, had the crank rods and pistons balanced, new everything, 1 piece bushings and 12 point rod bolts, deep oil pan, and while it does run very well, we have a problem holding the headgasket in, everything is straight and true, this time we are going to put new bolts in, if that doesnt work, probably going to go with custom studs. We also have a NA 310 that needs a head gasket too.
The 354 Perkins is an excellent motor IMHO, starts as good as the Waukesha, and good on fuel, and the turboed ones went up to 135hp IIRC. Nothing wrong with either of them but it costs quite a bit of $$ to get them "right". Do the same to the Perkins and itll run too, Dad rebuilt an 1850 back in the day with M&W pistons and he always said that was the strongest motor hes ever ran, its the one he wishes he hadnt sold. |

Dallas Center IA 515-720-2463 | Couple more things:
The late 1855 diesels had a 1955 engine with the built in oil cooler. The I-pump was detuned to give the 98 hp of the 1855 vs the 108 of the 1955.
There was a factory update for the early 1855 diesel engines. Kinda half ass, if you ask me.
A deal that screwed onto the oil filter deal. It was a heat exchanger. Had engine water running thru it to cool the oil.
Biggest difference between the 50 and 55 series was hydraulics.
The 50 models were open center which was fine if all you wanted to do was lift a plow or disk.
The 55 series have closed center PC hydraulics. Set up like the Deere tractors of the day. Way better than IHC, A-C, etc hydraulics.
No comment on the Perkins vs Oliver engine.
Did no have the best of luck with our 1850 diesel. And real good luck with the 1955.
