I think my pump is broken,,,, thought motor was stuck,, so bump-pulled it then motor fired right up,,, but hydraulics oil tank was empty,, filled it,, went empty again,,,,,, soooooo, pretty sure I fractured hyd pump housing.. I have changded that pump in a 770 before,, no so bad,,but not a good time or year to do it,,,,, so,,,,, looking fr an Oliver,,, w or without loader,,, I can transfer loader to different tractor. My question is,,, a loader on a Super 88, should fit any 77-88 Super and non Super,,,, 770 880,,,, even a 1600, 1655,,, is the frame the same on all these series' tractors ??

1650 fly wheel

Posted by Gerald Hubbling on November 26, 2018, 7:57 pm

I have a 1650 gas, having starter issues. The drive binds up in the ring gear and to get it loose I have to loosen the bolts on the starter. Planning to pull the engine this week to replace clutch. Was wondering can the ring gear be replaced on the flywheel?

Re: 1650 fly wheel

Posted by arnie on November 27, 2018, 8:23 am, in reply to "1650 fly wheel"

Sure you can if you have a good torch. Elevate the flywheel an inch or two on something on your work bench. Take the torch and slowly go around the ring gear and heat it until it falls off the flywheel. Now turn the flywheel over and let cool. Set the ring gear in place and slowly go around heating the ring gear "EVENLY" until it drops in place. You may have to coax it "lightly" to get it to fall in place. Let it cool by itself. No water. After cool using a brass drift tap it all the way around to make certain it is fully seated. REMEMBER that the beveled edge of the teeth goes toward the starter. Also look to see if the ring gear is really bad. We replace more starter drives than ring gears. The starter may have a bent armature shaft. Take it to a good automotive electrical repair shop for a rebuild. Arnie

Posted by Gerald Hubbling on November 27, 2018, 10:49 pm, in reply to "Re: 1650 fly wheel"

Thanks, just replaced the drive, broke the old one in half. Just have to get engine pulled and see what I find. Maybe should pull starter off and see if its bent.

My online search doesn't come up with a new ring gear, any idea where to find one?

Re: 1650 fly wheel

Posted by Gerald Hubbling on November 27, 2018, 10:52 pm, in reply to "Re: 1650 fly wheel"

Some where I seem to remember Larry saying to in stall the flywheel 60 degrees off how it is now, I assume it installs with six bolts.

Re: 1650 fly wheel

Posted by Arnie on November 28, 2018, 8:21 am, in reply to "Re: 1650 fly wheel"

The flywheel is doweled to the crankshaft. You cannot change it. If you did the timing marks would be off. I found a ring gear at AGKITS. Phone 800 437 3609...OEM # is 101765A.. 111 teeth. Always count before ordering. Have a good one. Arnie

880 helical poly bushing

Posted by Paul on November 22, 2018, 2:59 pm

Hello Larry
I bought a new shaft and poly bushing for the main shaft. The bushing fits over the shaft loosely. It is a tight fit in the gear. When installed in the gear it is very tight on the shaft. I will have to force it on. Perhaps a puller to squeeze it. I have honed the gear out and may take a little more. I'm also considering honing the bushing. Seems to be to tight.
Is there a procedure to fit it to the shaft?
Thank Paul


770 power steering

Posted by jim on November 20, 2018, 12:44 am

what year did they start the newer power steering like the system on the whites, the short turn steering? and do the hydraulic systems from a 77 work on 770

Re: 770 power steering

Posted by Larry Harsin on December 11, 2018, 8:15 am, in reply to "770 power steering"

In the mid-sixty's. Hydraulic system from a 77 will fit on a 770. Larry


timing 770 oliver

Posted by jim on November 20, 2018, 12:21 am

when timing a 770 gas with a light at about what degree advance do you set them at an idle

Re: timing 770 oliver

Posted by Arnie on November 20, 2018, 10:58 am, in reply to "timing 770 oliver"

Book said TDC at low idle. Max advance 25%. If the engine is running smoothly and the light shows the timing mark to be "jumping" around you may have wear in the distributor. Flyweight pins, flyweights, or loose shaft bushings. Loose shaft bushings can cause point gap to change which can change timing. Not much, but some.

Replacement Engine for Oliver 77/770

Posted by Ken on November 16, 2018, 9:21 pm

I have a 1958, Industrial Oliver 770 that was made for the Corps of Engineers, under a Government contract. The engine was essentially worn out when I got the tractor and I have gotten the last of its life. I am considering replacing the engine if I can find a usable engine in fair to good condition. The engine in the tractor is a 185GM, 6 cylinder Waukesha with Serial No. 1077315. It has the military's 24 volt system.

I am located in Durango, Colorado, quite some distance from the midwest where there are many Olivers. I am a backyard mechanic but not an engine rebuilder thus I am looking for an entire Waukesha 185 engine with either 6 or 12 volt system components(starter, generator/alternator, distributor, etc.) that will couple-up to my existing tractor. Please counsel me on how to find a usable/reliable engine for a fair price. Shipping options will be a subject for another day.

This would be a good starting place. All States Ag Parts Phone 866 609 1260 They are a group of several yards around the country. Possibly one in your area. If they are unable to help they may be able to steer you to another yard. Go to Google and type in "used tractor parts" There are very many good yards out there. Good luck Arnie

I found some additional info. The sheet metal in these photos say it is a 77. Grill and the ability to put side shields on. Probably had them when new. Appears to be an Ag tractor with yellow paint. The twenty four volt will have no bearing on engine replacement. Where did you find the ser. #. The engine from an Ag tractor should fit.

1650 cockshutt servo valve

Posted by Adam smith on November 16, 2018, 5:28 am

Hi Larry.

I just put a new hydraulic pump in my 1650 cockshutt and now that I have it back together my 3 point hitch arm go up to the top position and put the engine under load and wonít go back down. I took the top off to look at linkage and everything seems to be intact. When I loosen the servo valve they drop. It seems like lower spool was stuck but even when I push onthe lowering spoil while it is under pressure before I loosened the servo valve it did nothing. What would cause the oil to stay in the lift cylinder and not return to the oil sump?

Re: 1650 cockshutt servo valve

Posted by Arnie on November 17, 2018, 6:45 am, in reply to "1650 cockshutt servo valve"

Did the three point work before replacing the pump? I put a new pump in a 1500 years and ended up with the same problem. I seemed to get the linkage up side down or out of sequence when I reassembled it. Arnie

Re: 1650 cockshutt servo valve

Posted by Adam Smith on November 17, 2018, 3:32 pm, in reply to "Re: 1650 cockshutt servo valve"

Thank you Arnie for your response! Your assisted knowledge is greatly appreciated. How far out was your linkage , and do you remember if it was the servo valve linkage or the draft control linkage? The movement on the piolet spool seems to be very small. But if I flip the linkage it is to far away from piolet spoil. When I took the main hydraulic tower off I didnít remove the rock shaft cover at all. What do you think happened to you during your pump replacement?
Again thank you for your help.

Re: 1650 cockshutt servo valve

Posted by arnie on November 17, 2018, 7:51 pm, in reply to "Re: 1650 cockshutt servo valve"

Lots of years ago. But I think it was the draft control linkage. If that linkage was incorrect the 3 point which is operated by the rockshaft would not work as it should. I also seem to remember that the 3 point lever was not working as it should. I think I had to remove the rock shaft cylinder to correct the problem. Did you have to remove the rock shaft cylinder to install the pump? Good luck. I'll be interested to know what happens.


Oliver 70 Row Crop Tyre Size

Posted by Richard Chivers on November 14, 2018, 3:20 pm

Hi Larry and everyone
A question. My 1937 70 row crop rear tyres are 9.00 X 36 ?
All the information I can find out says they either had a 24 inch or 38 ? There is nothing about a 36 inch tyre (Sorry Tire) They are on cast iron rims and the whole thing I was told is as it came over here in the 30's.
Did they make them with a 36 inch tire.
Any information gladly welcome.
Regards Richard


Oliver 70 row crop wiring

Posted by Richard Chivers on November 13, 2018, 10:59 am

Hello
I have 2 Oliver 70 Row Crops, one is a 1943 gas with electric start, Magneto ignition and (Dynamo Charging) Generator. The other that I have just bought is a 1937 crank start. The 37 is in original condition and has what I assume is a Potato ridger underslung, so a compleat tractor that I can take to a show. What I would like to do is put the starter motor, Generator and new lights on the 37 taken from the 43. On the lighting circuit it will be a new installation. Is there anyone out there that can tell me the routing of the wiring as all I can see from pictures on the web is that it looks like it goes over the top of the fender through a plastic cover and then dissapears. Can anyone help on the routing.
Regards
Richard

PTO Control Handle Pin

Posted by 77RowCrop49 on November 10, 2018, 9:16 am

Hi Larry, Trying to remove the PTO control rod so I can clean up and paint around it better. Parts manual describes the pin that keeps it on the shaft two ways;933 215 says 1/4 x 1 1/4 pin, spring and 932 555 calls it 5/16x11/2 groove pin, hex head. One end looks like it has a rounded head that is nearly flush with the control handle. The other end looks like it may have had something that came through and was peened over. Don't see anything that looks like a hex head. Could there be anything other than a straight pin in it? Is there anything to do other than grind that peened end flush and then drive it out from that direction?

Re: PTO Control Handle Pin

Posted by arnie on November 16, 2018, 5:42 am, in reply to "PTO Control Handle Pin"

Larry may still be busy in the field. Maybe I can help. A spring pin is slotted from one end to the other. It is hollow and you should be able to push a thin wire thru it. But you have described a tapered grooved pin. One end is a larger diameter than the other. Because it is tapered it has to be driven out backwards. If it has been peened over grind it off and drive out. But it can get a peened look from driving it in during assembly. You may need to remove the lever and cover assembly to get a straight shot at it. Always use a new pin. Good luck. Arnie

super 55 that misses on no.one cylinder

Posted by Kevin Daugherty on November 9, 2018, 9:27 am

i have a super 55 that does not fire correctly on no. one cylinder. after a compression check it has around 115 lb and it has has new new distributor cap wires and plugs . any thoughts would help. thanks

Re: super 55 that misses on no.one cylinder

Posted by arnie on November 9, 2018, 11:30 am, in reply to "super 55 that misses on no.one cylinder"

It is possible for an engine to have a bad head gasket and still have good compression. What do the other three cylinders read. Is there a great variance between the cylinders. Try this. Start the tractor and get it warm. Shut it off and go back the next day, Start the engine and immediately shut off. Remove the # 1 plug and look for water droplets on the electrodes. That could indicate a leaking head gasket or a cracked head. Look for oil in the coolant. That would indicate an internal leak. Also but not common is a chronically sticking valve. Also timing and point gap. Try interchanging the plug wires. If the problem moves to a different cylinder, you have a bad wire. Good luck..

I would check the local tractor dealers. They would most likely know of someone in your area who does that kind of work. Or maybe you have a Vintage tractor club near you.


PTO shaft removal on 1755

Posted by Greg M on November 8, 2018, 8:48 pm

I am in the process of removing PTO drive shaft from Oliver 1755 to overhaul engine. According to manual the shaft is located in top PTO housing under the bolt on cover. Is there a snap ring i need to remove before the shaft pulls out?

Any tips/suggestions to make the removal process go smoothly?

Thanks

Re: PTO shaft removal on 1755

Posted by arnie on November 9, 2018, 11:42 am, in reply to "PTO shaft removal on 1755"

This should work. Remove sheet metal plug on rear of PTO housing. Remove snap ring. Thread a 1/2 inch rod into plug and remove. There is an o-ring to remove. Having an O-ring "pick" helps. There may be a second snap ring. Than using the same 1/2 inch rod pull pto shaft out. If it slides rearward a short distance and stops, push it back in a little, turn a little and try again. Splines have to line up before it can be removed completely. Always reinstall with new O-rings.

Hi itís super easy to remove the shaft. Do all the stuff that was mentioned. Then take a long 12 inch bolt thread it in pull shaft out till it hits the clutches. Then hold a litt pressure outward and take a impact wrench and just rattle it a little donít spin it just vibrate a little and shaft will slide right out same thing to put it back in. 570-362-4169 of you have trouble.

Re: PTO shaft removal on 1755

Posted by Greg M on December 24, 2018, 10:55 am, in reply to "Re: PTO shaft removal on 1755"

Finally had time to try removing the PTO shaft from the 1755. I am stuck at second base. Removed the retaining snap ring and installed bolt to remove plug. I cannot get the plug to budge at all. The plug is back into the splined female sleeve about 2 1/2" back. I am assuming the plug is not splined and should slide out without any turning and aligning with the splined female sleeve?

There is some rust on the splined female sleeve so i am assuming the plug has rust around it also. Am thinking of installing a slide hammer to help remove the plug. Is this recommended or will I mess anything up?

Steve, I may give you a call after Xmas for some advise on this.

Thanks Greg M


White 1370

Hello, i have a white 1370 tractor split apart that i am replacimg the clutch disc. I cant seem to find any info on how to bench set the clutch before install. It has the 6 finger style clutch. Can you help?

My email is kellykristianson@gmail.com

Thank you!

Re: White 1370

Posted by arnie on November 2, 2018, 5:38 pm, in reply to "White 1370"

The clutch disc and pressure plate have to be bolted with shims (if required) to the flywheel weather it be on the bench or on the tractor.

Re: White 1370

Posted by arnie on November 2, 2018, 5:40 pm, in reply to "Re: White 1370"

Re: White 1370

Posted by Kelly on November 2, 2018, 11:26 pm, in reply to "Re: White 1370"

Ok. Do you have any specs as to finger height of tge pto and main clutch fingers? When i disassembled the clutch there were no shims present. Also, the bolts that screw into the pressure plate are they supposed to thread into the fingers or are tgey just guides?

Re: White 1370

Posted by arnie on November 3, 2018, 6:50 am, in reply to "Re: White 1370"

Now you got me. My knowledge is more oriented to the green Olivers. I did put a clutch in a gray one some years ago but the setup was different and I don't recall. Sometimes that info comes with the new parts. Maybe you have a use to be White dealer nearby. Also you can get a manual from the Floyd County Museum at Charles City, Ia Phone 641 228 1099


Oliver 1650

Posted by Doug on November 1, 2018, 3:51 pm

Larry,
Why would I get fuel in the oil? Shows making oil on the dipstick. 10 lbs. oil pressure. Waukesha Direct injection Diesel.
Thanks

Re: Oliver 1650

Posted by Arnie on November 2, 2018, 6:20 am, in reply to "Oliver 1650"

Does your engine have a mechanical fuel pump on the right front side of the engine? If so it may have a ruptured diaphragm in the fuel pump. That would allow fuel to pass thru into the crankcase. Also it will cause the crankcase level to rise and it will cause oil dilution resulting in low oil pressure. Change the pump, oil, AND oil filter.

Re: Oliver 1650

Posted by Doug on November 2, 2018, 7:34 am, in reply to "Re: Oliver 1650"

I recently had the injection pump rebuilt. I probably messed up installing it.

Re: Oliver 1650

Posted by Arnie on November 2, 2018, 8:10 am, in reply to "Re: Oliver 1650"

It is not likely a recently rebuilt injection pump is dumping fuel into the crankcase but possible.

Re: Oliver 1650

Posted by Doug on November 2, 2018, 10:08 am, in reply to "Re: Oliver 1650"

OK. I will replace the fuel pump first. I really donít want to pull out the injection pump again.
Thank you Arnie!

Re: Oliver 1650

Posted by arnie on November 2, 2018, 11:53 am, in reply to "Re: Oliver 1650"

There is a way to check the fuel pump. Remove engine, plug one line fitting with you finger and try to blow thru the other. You should not be able to blow into one fitting if the other is blocked. Not fool proof but may help.
