Hi Larry can you tell me did Oliver 990 come out with front wheel weights or was there a front chassis bracket with suit case or slab weights ? If so do have any .Cheers Mark

I think they had front wheel weights. I don't have any front wheel weights for a 990. Larry


Oliver 880 Power Booster

Posted by John Rightenour on May 28, 2018, 3:49 pm

Hello, I have an Oliver 880 gas with a power booster, I can start out in the low side of the power B.,and shift into high without any issues but it will not lock in if I pull it back to the low side. Also I was at a pull Saturday evening and when I came home and unloaded and backed it into the garage, I noticed it was dripping oil and it was coming out directly under the power booster. I put a bucket under it and it only leaked about a half of a quart. I was wondering if there are any power boosters available, or should I just eliminate it? Any help would be greatly appreciated. Thank you, John

If it was mine, I would consider eliminating it. Larry


1655 Diesel starting issues

Posted by Joe on May 26, 2018, 4:33 pm

Hi Larry, I have a 1655 Diesel that has always been a little hard starting when cold. It would smoke but take some cranking to catch. A week or so ago it quit smoking while cranking. I went thru the fuel system and cleaned out some crud and it is getting good fuel flow to the injector pump. I pulled the return line apart and did not find any debris and has flow going back to the tank. When I took a line of going to an injector it didn't seem to have a lot of push behind it. If I leave the battery charger on the tractor set to the boost setting on it will crank fast enough to finally catch and run. It runs smooth and has OK power, but if you shut it off and go to start right back up it takes cranking to get it to catch. The starter is spinning pretty good during this attempt. Do you think the injector pump is going out? I was told it was new when I got the tractor a few years ago. Thank you!

Are you sure the lift pump is doing its job?

This one does not have a lift pump but my other one does

There are lots of things that can cause hard starting. It can be electrical. It can be fuel related. It can be low compression. Or a combination of all. Larry

mfwd parts available?

Posted by Mike R on May 24, 2018, 4:08 pm

Are there parts available to repair the original ball-type knuckles on the Clark mfwd Olivers? Or do you just have to convert to the newer axle shaft and knuckles? Any info is appreciated!

I think parts are available. You have to check with your AGCO Dealer. Larry

1655 Diesel lost power

Posted by Brett Schmit on May 19, 2018, 5:26 pm

Was running my 1655 diesel down the road and I noticed that the engine speed had slowed down. Went to pull a small hill and it didnít have the power to make it up. Made it home and shut it down, started up a minute later and it runs fine. Any ideas? Iíve changed fuel filters and air filters. Has a clean tank and sediment bowl.

Re: 1655 Diesel lost power

Does your tractor have the lift pump on the right side of the engine? If it does, it may have a bad check valve. If your does not have the lift pump, you may have trouble with your injection pump. This could be a governor ring that is breaking up and particles plugging the outlet to the return line. Larry

I had the same problem with my 1655. Problem was there was a June bug floating in the tank and would get sucked into the outlet and block the flow. Shut off the tractor and the bug would float away and it would run fine until the next time. Remove the shut-off/sediment bowl and flush the tank. Bet you'll find some crud that will pile up and block the flow.

Back in the days when I was first learning about Olivers, I had the same thing. But my obstruction was an acorn instead of a June Bug. Larry

Ended up loosening the fitting in front of the check valve when the tractor started running rough and it started to run fine. Took the check valve a removed the glass ball inside and itís been running good ever since. Thanks for your help Larry and Roger. Odds are that the injection pump is starting to go out I suppose.


Bigger tub on 770

Posted by Andrew Hansen on May 16, 2018, 1:27 pm

Larry, what tubs are compatible with the 770 year-end and would still fit the 770 sheet metal but might offer more room for a larger flywheel housing or wider block? Still thinking about the 3-53 to make an interesting toy for my son (coincidentally his name is Oliver) to work on as a project but I don't think the GM will fit down low enough in the row crop 770 tub. I would like to retain the sheet metal and the row crop standard front axle, would that all still fit on a 1650 tub, for example, if it was wider inside?

Thanks,
Andrew

Posted by Larry Harsin on May 18, 2018, 6:50 am, in reply to "Bigger tub on 770"

There is nothing I now of and I don't think so. Larry

Posted by Andrew Hansen on May 18, 2018, 7:36 am, in reply to "Re: Bigger tub on 770"

Larry would a 16XX series tub bolt up to the 770 transmission housing? Are they a longer tub?

Posted by Larry Harsin on May 21, 2018, 8:42 am, in reply to "Re: Bigger tub on 770"

I don't know. Larry

Posted by Larry Harsin on May 21, 2018, 9:54 am, in reply to "Re: Bigger tub on 770"

After thinking about this for awhile, I thought you probably meant a 1600. Yes, I think that tub would bolt right up. As far as length, it may be a little bit longer, not are. Larry

Posted by Andrew Hansen on May 22, 2018, 1:33 pm, in reply to "Re: Bigger tub on 770"

Ok, so a 1600 tub is different than a 1650? That's great information, thanks very much!

Oliver 550 tansmission

Posted by James Eberle on May 12, 2018, 9:42 am

Will a 550 transmission bolt up to the Super 55? Are there any differences? If they're the same, what other parts will fit the Super 55? Front axle? Engine?

I'm looking at a salvage Oliver 550 on CL to possibly help out my 2 Super 55's.

Posted by Larry K on May 12, 2018, 7:18 pm, in reply to "Oliver 550 tansmission"

I have restored a Super 55 and a 550. according to my parts books the parts difference is the sheet metal and the 550 has a pressurized radiator

As Larry K. says, almost all of the parts are interchangeable.. Larry Harsin

770 Diesel motor replacement options

Posted by Andrew Hansen on May 11, 2018, 9:33 am

Hi Larry,
First time poster, but have learned lots from this site over the past year or so.
I recently bought a '59 770 diesel from a guy who had got it running after sitting for 7 or 8 years. He had the head rebuilt and replaced injectors, etc. Ran ok, but didn't start well and smoked badly. I found as well that it had virtually no oil pressure. I decided to pull the motor and freshen up the bottom end at least, and there was lots of evidence of it having sat for years and maybe not having been well looked after to begin with. Long story short, after having it in the tank to clean all the rust out around the sleeves, my machine shop guy found a crack right from the deck down through a main on the 3rd cylinder - it's junk.
So i need to know what I can look for as a donor tractor. 77 through 1550? Is the gas the same block as the diesel? And any idea how hard a 3-53GM swap might be?
Thanks,
Andrew

Posted by Larry Harsin on May 12, 2018, 8:54 am, in reply to "770 Diesel motor replacement options"

A block from a Super 77 on up through 770 will work. Even a 1550 block will work. I have a block for $500 plus shipping if you need one. Larry

Posted by Andrew Hansen on May 14, 2018, 2:11 pm, in reply to "Re: 770 Diesel motor replacement options"

Hi Larry, thanks for the info. For the block you have, do you know if the sleeves are salvageable? And are the gas and diesel block and internals the same other than the crank?

At this point, I am trying to limit the damage to my wallet, so if I could find a wrecker with a full motor it might be cost effective. Are there other options for a full motor swap, such as a 1600 or 1650? Just trying to broaden my search options.

As for the Detroit, it's looking like even the SAE 4 flywheel housing won't fit in the tub, does that seem likely?

Thanks,
Andrew

Posted by Andrew Hansen on May 15, 2018, 2:19 pm, in reply to "Re: 770 Diesel motor replacement options"

Larry, I have a line on a complete and good running 283 diesel out of a 1650, what would it take to make that work in a 770?

Thanks,
Andrew


Oliver 1855 Diesel in oil

Posted by Wes Blevins on May 10, 2018, 11:59 am

Larry-
On my 1970 1855 Diesel I'm getting a large amount of fuel into the crankcase. I'm leaning toward either a cracked injector nozzle or possibly a seal on the injection pump. I was curious if there way a way to test the seal on the pump before I removed it. My thoughts were possibly cap the injector lines at the pump and apply a small psi of air to the inlet side of the pump and see if it leaks down. Does this method seem logical to you, or is this a bad idea? Thanks in advance for any thoughts.

Re: Oliver 1855 Diesel in oil

Posted by Larry Harsin on May 11, 2018, 8:42 am, in reply to "Oliver 1855 Diesel in oil"

To test for league around the injection pump seal, shut the fuel off on the bottom of the fuel tank when you park it. Larry

Re: Oliver 1855 Diesel in oil

Posted by arnie on May 14, 2018, 1:45 pm, in reply to "Re: Oliver 1855 Diesel in oil"

If it has a mechanical fuel pump it may be leaking thru the pump into the crankcase. I just had one do that.


1973 Cockshutt 1755 wheatland

Posted by Shane on May 8, 2018, 9:25 pm

I have a 1755 Wheatland that the front wheels will go into a wobble at high speeds, if you slow down a little,it will quit. Both wheels do it at the same time. Tie rods dont seem bad, where should I start, tie rods or is it the piece under the tractor where the tie rods connect.
Any help would be greatly appreciated. Thank you.

I really can't tell you what the problem is without looking at it. You'll have to figure that out. Make sure the pitman arm is tight on the batman shaft. Larry
