1800 Puller?

Hey guys. I'm an oliver fan that likes truck/tractor pulling. We currently have an 1850 Diesel here on the farm with the perkins. Good solid running tractor.... But oh so heavy... I'm tired of hearing Olivers gettin' put down at the track.... So, I found an 1800A sitting in a lane off the side of the road not far from me.... Just rotting away. It's a gas, narrow front. I'd like to get it and put a 5.9 Cummins in it turning between 300-400 horse.... I'd use it here on the farm for wagon duty and maybe running silo blower, etc.. (Plenty of horses!! :lol: ) I figure an 1800 narrow front could be shaved down into the 7500 lb class.... 9000 lb for sure.....

My question is, will an 1800 Hydra-power/transmission/rear end hold up to 300-400 hp? These would be higher-revving horse power (most cummins love to turn 3500 ish RPM's when turned up) I plan to use a 5.9 cummins industrial block that was 175hp stock and turn up the IP, faster governor springs, and put some performance injectors in it... Trying to keep the fuel economy managable as I'd still like to use it for some things too... Probably just run a stocker Dodge turbo as it's easily good to 300+ hp...

Also, for what it's worth, I'd certainly run synthetic fluids throughout.....

Let me know what you guys think...... I think I might be able to get this old beast cheap... It's just rotting away out there, and needs to be rescued.

It would be a good project but what will you have in it when your done? How much will it cost to convert it over to a cummins? I've only found one place that made a conversion kit and it is $2500. Do some looking on the oliver forum, there's been alot of talk on this lately.

I'll do the conversion myself...... I have access to a local retired machinist for any parts I need made.... I have the cummins here already. Just needs rebuilt. The conversion doesn't really scare me that much.... The unknown strength of the rear-end does.

This rearend should be able to handle that kind f ponies so long as you don"t try and lug it . Remember 400 hp @ 7500 lbs is going to be a real wheel spinner. I have a 1855 with a 5.9 pushing 500 that runs in the 11000 and 13000. The rearend wont break but the hydraul shift and clutch dont last long.

Right. I heard that low-rpm torque is what bombs these most the time. The low RPM stuff will be actually more when working around the farm. Probably will dial the IP back when not running competition.

Clutch I'm not too worried about..... I'm a dealer for Valair clutch which makes performance clutches for the Dodge crowd.... I doubt it'd be much problem for them to work over an Oliver pressure plate and make me a custom ceramic/kevlar disc to go with it..... I'll be fine then.

Wonder if there's anything that can be done to the Hydra-Power to make it hold better? I'm thinking along the lines of the automatic trannies in diesel pickups where they up the line pressures etc to hold more ponies.....

Also, does your 1855 have the additional support for the ring/pinion like the 1950-T's did or no?

I've had a couple friends do this conversion, and the easiest way is use an 1850 diesel tub. The original tub on an 1800 gas will not be wide enough. Also the chain coupler between the hydra-power and trans will be a weak spot. Case in point, on the White 2-105 and bigger tractors they used a trunion mount instead. Lining up the chain coupler will also be a challenge because you will have to make new motor mounts for the cummins. If you are really serious about using it on the farm, I would find a 310 diesel with a turbo and install that instead. Alot less work, and these are very powerful engines for their size. I think 150 horse is attainable, and you would still be competitive at pulls. I'm curious, what does a 5.9 cummins weigh? If its more than the 283 gas you might need more than just pressed steel wheels to get into 7500 class.

I have a stock 1800 rear end on my 2255 puller.
Holds up fine. I am using a 3 disk clutch and have eliminated the hydra power with a shaft.
21 MPH road gear runs. I have it set up as a Pro Farm, 11,000 lb.

Good to know that the 1800 rear-end will hold up.

So, would need an 1850 tub frame then.. Hmm. Ok. I know I'll need an 1850 bellhousing..

I know the mounts will be a challenge... Have some ideas on that part.

A dressed 5.9 cummins in a dodge Pickup is like 950-1000 lbs.. But that also includes a powersteering/vacuum pump, and AC pump too.... Don't know how much a 283 weighs......

any video's of it? You're running the 3208 Cat? If I wanted to make power Id definately go with a 5.9 cummins over a 310 waukeshau.

I'll take the 3208 over the 5.9 for HP.

What are your profarm rules? What rpms are you turning? What sized turbo can you run?

That is impressive machine!! Do you mind if I ask how much HP that thing's pushin? Plenty from the looks of it....

Me? I'll take a 5.9 any day, but I like the 3208 for a couple reasons and that's because it's A Unique and B Stock motor for that tractor..
