Is this 1850 really a 1750?

[Olly1850]

Hi all. Just bought an 1850. That's what the hood says anyway. Dash matches. Rough, but kinda cheap deal. Runs okay, gears okay, new clutch, injection pump rebuilt, pretty nice rears, fronts a little cracked. I'm okay with it.
The original 354 has been changed? It has a 310 now. No turbo.

I don't know anything about these tractors other than what I've read here and the usual youtube suspects. Any ideas about the missing Turbo? It kinda sucks being down on power that much. I can live without, but was expecting the whole enchilada. (5 bottom, 17ft disc)

What would it have taken to swap these engines?

Not all the 310s were turbo'd. What are the casting numbers on the block? I would've done all I could to keep the Perkins, all things being equal.

"Dash matches" as in the serial number tag info corresponds to an 1850? If you don't know we can tell you if you post a photo or the info from serial number tag.

I'll be able to dig up more info in a couple days. It's not located near the house)
From a few pictures I think the dash looks like a 50, not a 55. Assumptions were made...

I was bummed about the 354 as well. It was part of why i went for it. I figured the horizontal pump was a later production or update or something.

It has the heat button on the dash, but i question if it does anything?
(Manuals just arrived this morning, but with the engine questions ya gotta wonder what is connected)

But it does run. And it was fairly close to the farm. And he delivered.

These pics are all I have at the moment. It was a rush kinda day.

Thanks for any and all info.

Are you real sure it's not a 1750? They would have a non turbo 310. The 1850 diesel would have the muffler on the right side, not the left, and I see there's no hole in the right side of the hood. Or maybe it's the other halves of the one I saw on Craigs List this morning in Ohio. Somebody has a 1755 rear half with an 1850 tub and a 354 Perkins. Priced cheap. Said it had a hydraulic issue two years ago and they want it out of there.

 

[Olly1850]

Well, that's the question. It doesn't look really butchered, maybe the hood panel got changed out? It's certainly no beauty queen.

 

[rrlund]

What's the model number on the tag down below the steering column? That's a 50 series dash for sure. Everything about it is screaming 1750 with 1850 spears.

 

[scootergmc]

Yeah, the hood could've been swapped but it looks like a 1750 to me. The 1850 diesel tub bumps out at the rear as opposed to the gas or 1750 tub, yes?

Also, bought this in central Missouri.

Ya, it would have to be either a 1750 tub or one from an 1850 gas for a 310 to fit.

Well, I put in a request for a ID tag pic to my brother (where this is parked right now).

Real bummer is buying manuals too quickly. Live and learn.

Does a 1750 work with a Turbo or is that a badly concocted idea?

Where in Central Missouri,? I'm in Clinton.
I've seen similar at Cook's Parts in Clinton.

No turbo on 1750. Look up Chris Losey that Oliver Guy on YouTube, or Ross the Oliver Man on YouTube. They have several model videos to help you learn from. GG Wes

Bought in Salem.

Model 275 - 22091
Serial 185-915-427

I've been wading thru videos. It takes a while...

My question on turbos, what is the short version of what is really different between the turbo and non-turbo 310 motors?
Normally a lot of small changes seem to pop up in places you might not expect.

 

[scootergmc]

I do believe you have a 1967 1750.

I like the na 310s. I would not turbo a 1750, or a 1755 for that matter. The turbo 310s were not known for reliability but if you decide to go down that road you would need to very much educate yourself on the turbo 310s and making them reliable. But they do have all the power you'd need.

I think you did right in trying to buy an 1850 but the Perkins is what you want. They were a very reliable 92 horse tractor, one of the best Olivers.

 

[Olly1850]

Got it. And much thanks!

I'm not trying to make it a hot rod, just wondering if the difference is worth the effort. I'm planning on leaving it alone for now. It's big enough to get by, but sure would have been nice to have the oomph i was expecting. It has yet to see any dirt at all. Or a car wash for that matter. So I have no idea how it runs under load. Everything is a layer of melting tundra right now so it will be awhile. I almost got stuck twice with the M just visiting a hay field.

Anybody want some really cheap manuals and a sticker set? Lol

More questions, cause you guys know a lot. Does the intake heater work very well?

Worst part is, you're going to have to change your name to olly1750. The heater works pretty good. The one on my 1850 does anyway.

 

[Olly1850]

Yeah, I was just thinking that. Oh well. I don't know if I can change the thread title? It's misleading now.

You can probably take comfort in knowing that if you find an 1850 you could sell the 1750 and offset the cost.

You're going to want to make sure the two speed works (the tractor will freewheel in under- so make sure your brakes are good if using on hills), hydraulic levels are up and you're not losing fluid anywhere (if the steering gets hard stop running the tractor), and you have good oil pressure. You may be able to peer down the oil fill hole with a camera and see if you have 12 point connecting rod bolts, indicating someone beefed up the engine at some point, but that was more of a higher power/turbo model issue. If it had a good previous owner there's a chance they may have done it anyway. Regardless, keep the oil clean and make sure the oil pressure stays above 25 psi. There's probably more quirky Oliver things I can't think of either. And if you don't know, on Olivers there's a long shaft that runs from the PTO to the flywheel, so if you need to pull the engine, pull the long PTO shaft first.

Welcome. Youtube is a great resource as Chris Losey's (The Oliver Guy and others') videos are fantastic.

 

[Olly1850]

I'll drop a camera in to check bolts.
Hour meter says 44xx and is working at the moment. But we know it is old so...

That shaft is a bit freaky to see.

It's been a mower tractor for a long time, and shows some front end damage for it. Tie rod ends were welded onto the rods. (Got new parts in hand already, now I hope they fit). It doesn't give me great hope that it was well maintained. But one can dream.

What's up with the steering? It works, but feels kinda stiff. Priority valve problems?
