Looking at an 1850 diesel that has set for a few years. It has had new pistons and rings installed and also an injector pump rebuild. When running, it purrs like a kitten but there are a few things I have questions about. The brakes do not work....I have read that they are mechanical. What is the fix and how much trouble? Also, there is oil leaking from a threaded stem on the left brake housing. Is there a seal to replace? It is also almost impossible to steer, but I found it a little easier to steer if you actuate one of the handles for one of the remotes. The 3-pt. lift works fine and the pto seems to work fine(it turns while the tractor is running....haven't put a load on it yet to truly check it). Does the lever on the right side of the driver's seat act as a brake for the pto or does it have some way of engaging or disengaging it? While pulled all the way back in the locking position, the pto shaft barely spins. It also appears that someone has done away with the hydradrive or over/under and went with a direct shaft to the sprocket(did I say that right?). I probably sound like an idiot with these questions, but I am new to the Ollies and everyone who frequents this board seems like a good bunch of folks with a whole lot of wisdom. I haven't heard anything but good about Olivers, especially the 1850, so I am going to give it a try....Thanks in advance and God Bless..... ..

The brakes are probably soaked with oil from a leaking seal inside the brake hsng. I would put in new brakes while you replace the seal on the bull pinion which is easy to do and doesn't require any special tools. The threaded stem is the adjusting bolt for the brakes It is natural for just about any oliver for the PTO to keep spinning even when back or in brake postion. THis is probably caused by warped clutches or just the turnbuckle on the pto lever needs adjusted to make it lock in the brake postion harder. Pushing the lever forward engages the pto. They did make a shaft to eliminate the hydrapower trans. Did you check the hyd. fluid at the dipstick between you legs when sitting on the seat? It might just be low or air locked from sitting so long. Is steering easier if you open up the throttle some? If so, the hyd. pump might be bad, or you could have a blown O-ring somewhere causing an internal leak. Check the pressure at the remotes to see how the hyd system really is. If the price is right fixing it shouldn't be too bad if it is jsut little stuff.

Thanks for the follow-up and advice..... .The hyd. level was low and appeared to be milky looking. Could probably use a change out along with filters. Is there also a sump screen somewhere in the hyd. reservoir to check? Maybe it is dirty too. The steering really didn't get any better with increased throttle. What kind of pressure should I be getting at the remotes? By the way, the tractor has straight tin, new seat, good paint, no rust, and good tires(they held pressure for two years) and it is going for $3000. It sounded like a pretty good deal to me..... ..

I don't have the book in front of me right now, but hyd. pressure at the remotes should be at least 1500psi-2100psi. I'm just trying to rule out a weak hyd. pump and then hunt for other problems.

There is not a sump screen for the hydraulic pump uptake and to get to the hydraulic pump and the intake for the pump you would have to take the "top " off the transmission and rear end of the tractor . There is a filter for the pump in the bell shaped piece underneath the seat just in front of the cap(with breather ) you remove to check fluid level and to add fluid . The bell shaped piece has a bolt head shape on the front to help loosen and remove it . You might ry replacing the filter and see if that helps . I know an old Oliver mechanic who anytime there is a hydraulic problem automatically replaces the filter . A week or so ago I think there was a post on this web site from BA Star which suggested the steering problem you describe (poor steering that is improved by messing with the remote handle ) might be a priority valve problem (the valve is stuck) and Mr Star suggested some ways to correct the problem . You might try looking for that post . I think it related to a steering problem on either a 1650 or an 1850 but I am not sure of that .

The hydra drive and over/under shifters were an option on the 1850 so the tractor you have may have come from the factory like that . Also , when the auxiallary drive units failed some people removed them rather than rebuild them . I have a friend with a 1655 which had a over under shifter and when it failed the prior owner just removed it and went with a straight shaft .

I agree the oil in the brakes is a leaking seal at the bull pinion. The brakes on the 1850 are dry disc mechanically activated . The only way I can see for oil to get into the area you are describing is for the seal to be leaking . Problem is usually caused by someone leaving brakes in park position or brakes locking up and running tractor with brakes on , brakes overheating and melting rubber in seal so oil starts leaking into brake housing . Just remove ocver and you will find out if the seal is bad because there should not be oil in or around the brake pads .

Overfilling the transmission/final drive will cause gear oil to be pushed past the seals and contaminate the brakes as you suggest. Sometimes just removing the level check plug and allowing the excess gear oil to drain will stop most if not all the leaks past the seals. Of course, if hydraulic fluid is leaking out the pump and into t/fd, causing the overfilling, that must be fixed.

Excellent advice from M Kuhns, Sam M and Ollie. I also suspect the Flow Divider valve is stuck/sticking.Here is the link to the B A Star post that Sam M referred to. B A Star Post

You can see the Flow Divider valve in this picture, of my 1850. It has the Hydra-Lectric cable running over top of it. Please excuse all the dirt and grease. :^) third party image

Tractor sounds like a pretty good deal to me also. Myron KY

Excellent info. guys..... ...Your help is greatly appreciated. I will try everything out as soon as I get a chance. Also, if the problem that I run into is the hydraulic fluid leaking into the transmission/final gear drive, how much work are we talking about to get it fixed? I had the same problem with a Ford 6000 and had to split the tractor. Thanks, again....

Steering problem is probably the valve in the picture. I had an 1850 that would do the same thing. Remove the plug in the back of that valve and see if you can dislodge the piston inside. May have to remove the valve to do this. I had to take mine off because the cab would not let me get in to hit the end of the piston. Also the hydraulics are under the seat. Do not have to break the tractor to get to everything in the system. Hope this helps.
