Oliver 550 tachometer

IP: 208.126.167.182 Posted on September 27, 2014 at 04:23:15 PM by Scott

I have an Oliver 550 with a 158258A tachometer that does not work. Do you know anyone who rebuilds them

Metro Speedometer in Independence, MO 816-478-0116. But it might be simpler to get a new one from Korves Oliver. 618-939-6681. Larry


Oliver 1800 carbs

IP: 198.111.39.224 Posted on September 27, 2014 at 09:51:43 AM by Tom

I understand that the 1800c came with a Marvel Schebler 32-1 carb. I don't have a carb for the tractor I'm working on and was wondering if there are other acceptable models? I have read that the MS USX29, USX37 and USX44 might work as well. Could you please confirm or dispel this rumor? Thank you kindly.

I think any of those might work. Larry


550 PTO reassembly and adjustment

IP: 70.60.136.130 Posted on September 25, 2014 at 12:06:49 PM by Greg

I am in the process of reassembling and adjusting the PTO clutch after replacing the clutch disc. I have the PTO assembly back on the lower shaft, however, I cannot get the PTO lever to break over the center to engage the clutch. Do I keep tightening the adjustment nut, or is there something else I'm missing.

IP: 172.242.134.43 Posted on September 29, 2014 at 07:42:38 AM by Larry Harsin

If it is not engaging the clutch, you have to keep turning the adjusting collar clockwise. Larry

I have turned the adjusting collar until it is tight to the back of the pressure plate, but the pressure plate is not in contact with the clutch disc. This tractor is a 61 or 62 I removed 4 steel and 5 fiber disc, but should it have 5 steel and 6 fiber?

You need to put in 2 more plates. Larry

Is the engine clutch working properly? That will impact the problem that you have. Larry

Re(2): 1959 Oliver 550 shifter issues

IP: 67.197.141.114 Posted on September 26, 2014 at 02:43:09 PM by bryan

we adjusted the clutch, but in my fumbling around, i lost track of how many of the steel balls go into the shifting rods, as well as where they're located, do you have any schematics or diagrams that will show me this?...

You need to get a Parts Manual from Charles City. 641-228-1099. Larry


770 Oliver

IP: 64.89.211.22 Posted on September 22, 2014 at 01:36:51 PM by Jay Nunn

Am trying to find out if I need a pressurized or nonpressurized radiator cap for my 770 Oliver. serial # is 81906736.

Re(1): 770 Oliver

IP: 172.242.134.43 Posted on September 23, 2014 at 07:42:18 AM by Larry Harsin

It came with a pressurized cap. I like a 4 lb. cap if I can find one. Otherwise, you will have to use a 7 lb. Larry

That is normal. Just let the engine run slow until it builds pressure. Larry


88 power steering

IP: 209.91.107.131 Posted on September 21, 2014 at 04:58:52 PM by Mary Lou Brooke

How hard would it be to put power steering on my Oliver 88?

Re(1): 88 power steering

IP: 172.242.134.43 Posted on September 23, 2014 at 07:39:51 AM by Larry Harsin

The hardest part is going to be able to find one. Put an ad in Antique Power magazine (antiquepower.com). Ask for a Char-lynn Power Steering for your Oliver 88. Also check with your local salvage yards and see if they might have one. Larry


tachometer/rpm gauge

IP: 207.78.66.254 Posted on September 19, 2014 at 03:19:28 PM by Jeremy

Larry, I have a 550 that the tachometer stopped working while I was using the tractor. Any idea what could cause it? Thank you

Re(1): tachometer/rpm gauge

IP: 172.242.134.43 Posted on September 23, 2014 at 07:36:52 AM by Larry Harsin

You will have to research this and figure it out. I can't do this without the tractor here to study. Larry

A Super 88 would be a good choice. Larry


1655 oliver brakes

IP: 66.226.116.254 Posted on September 17, 2014 at 07:39:10 AM by Kent Lepper

replaced brakes on 1655 Oliver and now they lock up when touched. The book says to adjust by placing/removing shims. Over the years people "tried" to adjust the brakes with adjustment on the outside linkage. The book says to use this adjustment ONLY to adjust the pedals equally. I need to know where the outside linkage should be adjusted to so I can place or remove shims to get the 3.5 free pedal that the book calls for.thanks, Kent

Re(1): 1655 oliver brakes

IP: 172.242.134.43 Posted on September 17, 2014 at 09:15:39 AM by Larry Harsin

You adjust using the shims. When you put in new brake pads you put in enough shims so that the brakes don't drag. Then adjust with the adjusting bolts on the outside as per instructions in your manual. Larry

Re(2): 1655 oliver brakes

IP: 66.226.116.254 Posted on September 17, 2014 at 10:44:40 AM by Kent Lepper

Thanks for your reply. My manual says "DO NOT USE ADJUSTING NUT FOR INITIAL BRAKE ADJUSTMENT". Looks like you recommend taking out shims so they don't drag. Where do I set the outside linkage-somewhere in the middle of the travel??thanks,

You don't take out shims so it doesn't drag, you put in shims so it doesn't drag.. Larry

Oliver 990

IP: 38.121.112.209 Posted on September 9, 2014 at 10:09:36 PM by Chad

Hi Larry thanks again for the information on the 66. I have a 990 that has the same problem. Fuel is leaking into the oil pan also any thoughts on that would be helpful. Thanks Larry.

Re(1): Oliver 990

IP: 172.242.134.43 Posted on September 10, 2014 at 06:55:58 AM by Larry Harsin

I don't know what to say about that. You should talk to a "Detroit Man" about it. I don't know where you are to suggest anyone. Larry

Re(2): Oliver 990

IP: 38.121.112.209 Posted on September 10, 2014 at 08:57:41 AM by Chad

Thanks Larry I am in Avoca, Iowa. Avoca is 40 miles east of Omaha on I 80.

Re(3): Oliver 990

IP: 69.66.110.149 Posted on September 10, 2014 at 05:16:22 PM by Clint Bauer

Most likely place is the fuel lines under the valve cover. They can leak where they screw on the injectors or the head fittings. the lines are not that high priced . I would replace them all to be safe. There are also copper washers under the fittings that could leak but more than likely its one of the lines. It also has a fuel pump on it with a seal but there is a weephole in it so it should leak externally unless it is plugged.


Oliver 66 diesel

IP: 38.121.112.208 Posted on September 7, 2014 at 09:10:48 PM by Chad

Thank you in advance. I have a 1952 Oliver 66 diesel. The tractor runs good but gets fuel in the oil. What are some of the things it might be? I also was changing the oil the other day and had to fill the tractor up with fuel. I filled the tank to full and fuel started to run out of the oil plug, I thought maybe it was running through the overfill line, but would that run into the oil pan? I was also told that the fuel might be running through the fuel pump. Any help would be great thanks.

Re(1): oliver 66 diesel

IP: 172.242.134.43 Posted on September 9, 2014 at 06:30:50 AM by Larry Harsin

The transfer pump probably has a hole in the diaphram. You can get repairs from Korves Oliver. 618-939-6681. Larry


Need Diesel Fuel Line Reducer Part

IP: 73.189.71.48 Posted on September 3, 2014 at 06:43:28 PM by Mark

I am not familiar with diesel engine terminology so this may sound dumb but if it works great! I have an Oliver 88 with a Waukesha-Oliver 4.3L 6-cyl diesel engine. On the engine, the fuel line that goes to the piston closest to the fan connects to the "Carby" Their is a 3/8" male/female brass connector with a threaded reducer inside. That connector has stripped out. Any idea how to get a replacement?

Re(1): Need Diesel Fuel Line Reducer Part

IP: 172.242.134.43 Posted on September 4, 2014 at 07:32:30 AM by Larry Harsin

I'd just eliminate that reducer. I think it will work just fine without it. Larry


Oliver Restoration

IP: 209.251.131.75 Posted on September 3, 2014 at 03:42:10 PM by Brandon Wagner

I'm about to purchase a 1940 Oliver 70 that belonged to my grandfather. I want to do a complete restoration and keep it for show. Can you give me a name(s)of someone who does restorations? I don't have the space or knowledge to do it myself. Thanks!

Re(1): Oliver Restoration

IP: 172.242.134.43 Posted on September 4, 2014 at 07:27:01 AM by Larry Harsin

Where are you located?? There is a fellow in Ionia, IA, 641-228-4553 and another guy in Pennsylvania, 814-766-9929. This is 2 listed in the Farm Collector magazine. We don't know them or necessarily know about them. Larry

Thanks for the contacts. I'm in Florida and the tractor is in Michigan. I'll check these guys out.


Oliver 66 Band to Disc brake conversion

IP: 71.165.73.154 Posted on September 1, 2014 at 04:06:44 PM by Frank

My Dad would like to see if there was any way to convert his (one owner) 66 to disc brakes. I think there used to be a conversion kit back in the day, but are there any parts available today to make it work? Thanks, Frank

Re(1): Oliver 66 Band to Disc brake conversion

IP: 172.242.134.43 Posted on September 4, 2014 at 07:22:12 AM by Larry Harsin

I'm not aware of any conversion for a 66. There was for 77's and 88's, but not for the 66, that I'm aware of. Larry


oliver 70

IP: 108.16.84.36 Posted on September 1, 2014 at 11:12:24 AM by walt wilson

I have a 1947 oliver 70.i have had the starter and generator off and have had them both checked out and have been told that they are both ok. I installed a new custom fit wiring kit and wired it as per the wiring diagriam in the owners manual. ialso installed a new light switch which I wired according to the directions. the problem iam having is when I shut the tractor off the ammeter goes to the neg. side and with in a short time the battery is dead. any ideas? is the wiring diagriam in the manual correct? thank you! walt wilson

Re(1): oliver 70

IP: 172.242.134.43 Posted on September 4, 2014 at 07:20:26 AM by Larry Harsin

Recheck your wiring diagram. It maybe that the cutout on the generator isn't opening when you shut off the tractor. Larry
