oliver 1255 power steering not working

Posted by mark mcneal on September 29, 2018, 8:02 am

hello mr larry my power steering on my oliver 1255 sometimes would work and sometimes would not, now it doesnt work at all, can you give me some help on where to start, the fluid level in the reservoir is full, could a faulty gasket on the pump be the problem, or maybe the pump itself, thanks for taking time to help

Sounds like a dirty or damaged flow divider. Needs to removed and cleaned. If "scuffed" inside it will need to be replaced. We have an 1850 that was a problem for years. We would have to clean it a couple times each summer. After replacing it the problem is gone. Always replace the hydraulic filter when doing this.

1655 Hydraulics

Posted by Craig on September 26, 2018, 11:44 am

I am wondering where you tap into the hydraulics to run a loader without using the SCV's. Can somebody show me the locations and what size/type of fittings that I would need? I have a 3 spool setup to run the loader and grapple.

1949 Oliver 77 engine surging

Posted by Adam Jones on September 22, 2018, 4:08 pm

I bought the 77 at a neighbor's auction a month ago. Drove it home, and had a terrible time with the engine surging, usually at full throttle. I cleaned the fuel system, and rebuilt the carburator, and while the tractor does run better, it still surges at full throttle. Most of the time it goes away when you take off with it. Problem now is about 1/4 to 1/2 mile down the road, it will start surging until I back off on the throttle and it calms down. I've tried adjusting the governor, but that doesn't seem to do much. Do you think the governor needs more attention, or is it still the carb?

Thanks

Take the governor from the engine and look for internal wear. Fly weights, pins, bearings bushings, etc.. Also linkages can be a problem. Excessive wear at holes. We used to weld them shut and drill them to size. Also repair linkage rods back to size. Another place often overlooked is the throttle shaft bushings in the carb. And then final adjustment is important.

Oliver 550 gas charging system.

Posted by Brad Blystone on September 21, 2018, 7:29 pm

Larry,

The amp light on my Oliver 550 was staying on until the rpms were increased. So I had the generator and regulator repaired/replaced. Now the amp light stays on regardless of the rpms. When I disconnect the positive ground the engine quits running. Is this supposed to happen or is there something wrong. Also a volt meter shows < 12 volts with tractor at idle.

Re: Oliver 550 gas charging system.

Posted by roger wallis on September 22, 2018, 10:30 am, in reply to "Oliver 550 gas charging system."

Your newly installed generator needs to be polarized first to start with. Google that. Also any gasoline engine, without a magneto will quit when a battery cable is disconnected. No power to the ignition system. You might experience low voltage until the rpm's come up a bit to energize the generator.

oil pressure on 2-70

Posted by ronald deese on September 19, 2018, 7:47 pm

good oil pressure when first started 45 pounds. After about 1 hour it drops to about 10 pounds and idles close about 3 pounds. Thought about the pressure relief valve but mine does not have one under the alternator. Where would the pressure relief valve be located? Any other suggestions concerning the low pressure? Mine is a diesel tractor.

Re: oil pressure on 2-70

Posted by arnie on October 1, 2018, 3:46 pm, in reply to "oil pressure on 2-70"

I found a break down of the oil pump. The pressure relief is located in the pump if it is a Waukesha. Best I can do. Do you know the history of this engine. Number of hours. Last engine major, etc.

550 diesel smokes

Posted by David Abernathy on September 17, 2018, 2:13 pm

I have a 550 diesel that runs but has a lot of white smoke coming about exhaust. I suspect a bad injector. Any tips or help are greatly appreciated.

Re: 550 diesel smokes

Posted by Larry K on September 20, 2018, 2:52 pm, in reply to "550 diesel smokes "

Are you loosing any radiator fluid? Water from a crack or bad gasket in the cylinder can create white smoke.

Re: 550 diesel smokes

Posted by David Abernathy on September 20, 2018, 3:01 pm, in reply to "Re: 550 diesel smokes "

I pulled the head and I believe the problem was a blown head gasket. Now Im having trouble finding the torque specs for the head bolts.

Re: 550 diesel smokes

Posted by Larry Harsin on September 28, 2018, 8:26 am, in reply to "Re: 550 diesel smokes "

Those head bolts should be torqued about 100 lbs. Larry


Oliver 880 missing above 1800 rpm

Posted by Kurt Behn on September 13, 2018, 8:19 pm

Hi Larry,
My Dad recently bought an Oliver 880 gas with 3750 hours on the original tac. He has been having an issue with the tractor missing above 1800 rpm. It doesn't seem to make a difference if it's pulling something. The choke doesn't seem to help and only makes it puff black exhaust. He says the tank is clean and it has new plugs and points.

Any suggestions as to what the issue might be?

Thanks,

behnfarm@gmail.com

Frame width difference

Posted by Craig on September 13, 2018, 8:53 am

What is the difference in frame width from a 1650 to a 1750?

Re: Frame width difference

Posted by Larry Harsin on September 28, 2018, 8:20 am, in reply to "Frame width difference"

Mainly it is wider in the area of the fly wheel because the 1750 has a larger fly wheel and clutch. Larry


Oliver 1750 loader connection/hydraulics

Posted by Craig on September 13, 2018, 8:42 am

I bought a loader that came off a 1650. It had been plumbed in to leave the hydraulic remotes open. Where do I hook the three hoses up on the 1750 to do the same thing and leave the hydraulic remotes open?

Posted by Larry Harsin on September 28, 2018, 8:18 am, in reply to "Oliver 1750 loader connection/hydraulics"

The connections for the 1750 are the same as it was for the 1650 where the loader came from. If you can't figure it out, call me: 712-362-2966. Larry

Oliver 88 diesel clutch problems

Posted by Joe on September 10, 2018, 6:01 pm

I havd a Oliver 88 Diesel that while the clutch is pressed it does not disengage the transmission . Clutch has about one inch of play

Re: Oliver 88 diesel clutch problems

Posted by Larry Harsin on September 12, 2018, 9:18 am, in reply to "Oliver 88 diesel clutch problems"

It should work with that much free play on the pedal. If it has been sitting for a long time, the clutch disk may be stuck to the fly wheel. If this is the case, jack up one wheel and put the trans in 6th gear, have someone hold the clutch pedal all the way down and rock the jacked up wheel back and forth in an attempt to break the clutch disk away from the fly-wheel. If this does not work, you may have to take the clutch apart. Larry


Oliver 77 paint colors

Posted by Charlie Hays on September 9, 2018, 5:03 pm

Hello, As of yesterday I own two Olivers. I bought a Super 88 in May. The price was right and I needed a backup tractor. I ended up rolling more than 60 4x5 rolls of hay. The other green tractors were not available for several reasons. I'm 68 and my father farmed with a man who had a 66 back in 1964. Mr. Branaka's Oliver was a strong tractor, stronger than Dad's M-H 101 Jr. Anyway I really like the Super 88 and bought a 77 (1952 mfg date) at auction yesterday. The wheels are yellow. Is that the correct color? What should it be? Also, this tractor has been pulled. I may be looking for PTO, hydraulics, air cleaner. Do you sell used parts? Thank you so much for your help and time.

Super 55 Hyd system

Posted by JL Ray on September 4, 2018, 12:43 pm

First off I don't have my Serial # with me. I have a 1954 super 55 with remote hyd valve. the tank has the extend neck for more capacity also. I hooked up a 3 point Backhoe over the week end. I blocked the remote one way and away I went. I know the tractor does not have a big enough pump for this and things will work slow but that OK for now. The gage on my backhoe only reads 1000 psi and shortly after some time its 800 psi. Do I have any choices? Change oil and filter it next? Then what? Is there a relief valve I can adjust or is my pump shot? Or something else?

Re: Super 55 Hyd system

Posted by JL Ray on September 6, 2018, 6:50 am, in reply to "Super 55 Hyd system"

Thank you all for the help. After changing the oil which had water in it. My pressure came up to 1550. I think I'm all set.

Re: Super 55 Hyd system

Posted by Larry Harsin on September 28, 2018, 8:13 am, in reply to "Super 55 Hyd system"

I don't think your tractor was designed to do what you are asking it to do. The oil gets too warm and then it loses pressure.

88 diesel needs tlc

Posted by Aaron on September 3, 2018, 3:21 pm

An 88 diesel followed me home yeserday. I needed another project like a hole in the head, but I can't seem to say no to these things. It needs some help to make it a reliable useable tractor. Firstly, it starts hard. Needs ether or it won't fire. Previous owner said that this is a recent issue. It does run ok, but seems a little under powered and stumbles a bit at WOT. Some white smoke but clears up somewhat after running for a while. I'm thinking the lift pump but haven't tested yet. I'll check fuel flow and filter at the same time. Do they make a rebuild kit for the lift pump? The injector pump is the Bosch I believe. Tag has been painted over but the model number starts with psb.

It came with a loader. It was the real reason I bought it. The valve for the bucket likes to dump automatically at random. Any tips on what could cause the valve to suddenly shift? The pigtail of wires on the right side of the pump assembly have been cut. For now I'm going to switch the lines so that the bucket will curl instead of dump. Seems that would be less inconvenient.

Can someone tell me what model loader it is? Here is a picture I found online of another unit just like it.

https://i.pinimg.com/originals/90/cf/8a/90cf8ab5b206bcf5046b7bc442b234ff.jpg

I'll probably have more, but this is enough for now to get started.

Thanks,
Aaron

I found a sales flyer on line. Your loader seems to be a model 29 or 69.

Re: 88 diesel needs tlc

Posted by Aaron on September 6, 2018, 4:15 pm, in reply to "88 diesel needs tlc"

I've done quite a bit of investigation. I've studied brochures and manuals online, pictures, and other sources. I'm pretty confident that I have a hf9 loader. The model 29 appears to be an updated version of the hf9. It has two cylinders for the bucket instead of just one and some changes to the bucket linkage mechanism as well. The model 69 is round tube construction which is different than the 1" flat plate construction of the hf9 and 29. The brochure lists the standard capacity of the 29 at 1,000 lb and the 69 at 1,500 lbs. The max lift capacity of both the 29 and 69 is listed at 2,200 lbs.

I'm still working on the issue of the diesel not firing. I took the mechanical lift pump off and partially disassembled it. I didn't immediately see any holes or tears in the diaphragm. It's an AC pump but I haven't been able to determine which exact model. I put it back together then loosened the fuel line feeding the injector pump. I got what I thought to be pretty good flow out of the line when I cranked the engine over. Next step is to crack the fuel lines loose at the injectors and make sure everything is bled well and that I'm getting good flow there.

You can get a new lift pump from Kaoves ( pronounced: Core-vess) Oliver 618-939-6681. Larry


1250 Oliver fuel pump

Sir,

I have a 1966 Oliver 1250 diesel tractor. The pump is going out. I can still start it, but it does not get enough fuel. My plan is to price rebuilding the pump, if possible or selling for parts. Any suggestions?

Oliver 70 Tri-cycle Front end

The front end, -tri-cycle, of my 1940 Oliver 70 Row crop is binding and I can't get find the problem. I've taken it completely apart and it turns free, but when I reassemble it and tighten the 6 bolts mating the two pieces together it binds and won't turn freely.

You need to refer to an Oliver 70 Shop Manual. You can get one from the Floyd County Museum in Charles City, IA 641-228-1099. Larry
