1800 Oliver a and b differences

[Steve 1953]

What is the difference between the 1800 a and b Oliver? How are they labeled on the tractor? Thanks

 

[eeeeeeeeeeeeeee]

A's are checkerboard. B's are not checkerboard,but have the throttle by the steering wheel. C's have the throttle on the side of the hood, and are not checkerboard

The A series or checkerdoard has # 18 as the model. Serial # 90525 to 124395.The B series has 28 for the model. serial #124397 to 134683.

Also engine size.

I believe that the B and C also had pressurized transmission lubrication. Some of the first A's did not have the extra 4 larger capscrews holding the cast wheel to the hub. I don't remember if these were updated or not.

1800 A & B tractors have the same gear train and hydraulic units. The engines are almost totallly different. Easy way to tell A series have spin on oil filter(s 2 on a diesel) B series has a sock type filter. There is about 10 horsepower difference as well.

&nbsp;&nbsp;&nbsp;&nbsp;As others have stated, the "A" series <font color = #009a31>[b:654c4848f0]Oliver </font>[/b:654c4848f0]had the decal with the checkerboard design on the hood sides. &nbsp;The "B" series was the first model to use the clasp (spear) on the hood sides followed closely by the 1600 in the last of October, 1962. &nbsp;The clasp came from the <font color = #ff0000>[b:654c4848f0]Cockshutt</font>[/b:654c4848f0] tractors with the purchase by White Motor.


&nbsp;&nbsp;&nbsp;&nbsp;The throttle remained on the steering column through the "B" series. &nbsp;The "C" series had the throttle on the side of the dash because "C" had the tiltable column hydraulic steering.

Dwayne, I will add a little to your posting, but first I would like to ask you 3 question.

#1 Have you ever see one of the X-89 tractors that were the expermintal/prototype 1800's?
#2 How about one of the pilot run of tractors, and do you have any idea of how many were built in this group?
#3 Oliver built a few 1800 "A" series with front wheel assist. Have you ever see one?

I would like to add to your posting about the clasp (spear) that the decals were mounted on. The first Oliver 1600 decals were of the checkerboard type. The first advertising on those tractors show the checkerboard decal. I have never see anything on a Cockshutt 1600 with checkerboard decals.

Also, a lot of people don't realize that the 1800 "A" series were sent to Canada after the merger, and were red and sand colored and had Cockshutt checkerboard decals without the clasp (spear). The top of the grill had the Cockshutt logo, not a checkerboard (plastic) decal like the Olivers.

It was't until the company came out with the "B" series, like you said, did they use the clasp (spear).

I hope one of the editors of one of the Oliver magazines will write a article obout the 1800's, from designing the tractors in the fiftys, to the last of that model built in 1965.

I can answer question #3.In late August of 1961 I went out to tour the factory and there was an 1800 A diesel there with FWA. They had just done some work on it and it was going to Green Jiant. It also had an external hydraulic pump attached and had a hydraulic valve mounted to the fender that probably would operate 6 to 8 additional circuits don't remember for sure. My tour guide who had been my foreman on the Power Booster Program would not let me take a picture of it. He did tell me (he worked in engineering) that they had also made another unit but no decision had been made as to what to install it on. I am sure you also have a copy of the parts bulletin that covered the first FWA tractors and showed the 1900 A series with FWA. Also there were 2 of the prototype 1600 4 cylinder tractors there. Sorry no pictures of those were allowed either. They had the checkerboad decals.One of the people that posts on here has an 1800 A series Cockshutt. He sent me a picture and the serial number is in the 120 *** range. Firt physical proof I have seen of an 1800 A series Cockshutt. I also used to have a picture of an 1800 A gas with the two speed with the hand clutch that was removed before the tractors were released. Send me an e-mail I will be home most of this week and I will explain a couple other things. J.

Great info, I also would like to see one of the magazines do a story on the 1800 project. Maybe there is some prototype pictures out there just like the fascinating photos and article about the " corporate tractor".

Here is a picture of an A series.

I can not tell for sure if it has the old style wide front or not. If anybody is checking all the details, the manifold and carburetor are for a B or later model engine and the steering wheel is not original (Gemmer unit) either.J.

Right before the 1600 was introduced at least where I worked we had a nice colored picture of a 1600 utility model with a rear mounted cultivator (I think) that we showed out customers. Right now I am trying to remember how it was painted.

You're being awful hard on my tractor. Just kidding. It has the updated steering and I guess the later manifold and carb. Dad said they had the head milled and M & W dome pistons put in at one time. Maybe they changed the manifold then. He didn't say anything about that. Was a long time ago. The parts book shows a different part # for the intake manifold on an A series. Mine has the part # for the later one. I have changed both manifolds since this picture was taken. They both came off in pieces. I put on a set from a 1755 gas. All part #'s were the same. I also used the 1755 heat shield with a few modifications.

The wide front axle is the original it came with in 1960. It looks very similar to an 88 axle. According to the parts book this one is in the very first group. The first group for the center "tube" is 90525-115376. This one is 110931.
