 Topic: History of the 180 tractor
Posted: 04 Sep 2020 at 4:36pm |
The 180, was it a new tractor or based on something prior? I would assume it is the "six cylinder D17".
What's the story on finals, diff, transmission, torque tube,shared castings and parts...

A model One-Eighty engine/driveline is pretty much 100% a One-Ninety thru the differential. The final drives and brakes are upgraded/beefier/wider and evolved from the D-17. Even tho the transmission/rear end housing looks like a D-17, it isn't and it has all One-Ninety (eff s/n 9001 and up) components inside.

The Mighty- One Eighty- is when I got hooked on Allis Chalmers, I was working for a fella , very young- maybe 12,, he showed me how it all worked on the tractor- then he said fire it up - I did and that 301 diesel came to life ,, man alive that was a beautiful sound ,, nothing will beat that 301 hum/ and growl too !

It was originally going to have a 226 engine in the gasoline version running at 2200 RPM, but it vibrated too much because it didn’t have a balancer. So they were forced to go with the G2500 instead.

Wow didn't expect that. Still processing...
If you put drop down style final drives on a 190 type rear, isn't the
machine going to raise up, more ground clearance? With the 38" wheel option it would be way up there, no?
Then what about brake maintenance? I thought the 190 style brakes were easy compared to d17,d15,wd45. Are you back to pretty much removing the finals on the 180 for brake jobs? Were the 190 brakes no great shakes?
Confirm the 190 was derived from the D19.

If you stuff a 190 transmission (gears, bearings and shafts) into a modified D-17 rear end case, how does that raise the rear end up in the air ?? 180 brakes are hard to work on, just like a D-17 s3 and s4. The 190 was begotten from the D-19, yes. 190 in 1964. 170 and 180 in 1967. Have you ever looked at a 180/185 ??

Thanks DrAllis for info. The 180 is one tough non-turboed 2800 301. I know it has limited space where hydraulic levers rise up to operator’s seat & was probably cost prohibitive too, but wished AC had incorporated a more compact 190’s handy PD/throttle/hydraulics right hand console into the 170/180s.

That "console control" on the mighty One-Ninety's, XT's and 200's was unmatched for ease of use. That is for sure. Even A-C never had another control bay any nicer on models built many years after the original console control. Look at the 210/220. It was just D-17 series 4 controls raised up higher.

Ok, I understand, the rear is from the 170, not 190.
I don't recall seeing a 180/185. Allis-Chalmers are rare here on Long Island.

The rear end and final drives may look to you like a 170, but I can assure you they are NOT. Inside the rear end is all 190 transmission parts and the final drives are twice as wide as a 170.

In '68 or '69 Deere came up with a half hearted console control on the 4020. Deere people thought it was the best thing since sliced bread.

The 180,s and 185,s were probably some of the most dependable and rugged tractors Allis Chalmers ever built. Especially the diesels. Our 180 diesel run rings around 3020 Deeres in this country. It did more work and stood up better even though those folks would not admit to that. We had a gas 180 that was our loader tractor for a good many years. Didn't have the torque of the diesel and used more fuel. Did alot of work on a 180 still use our diesel to this day. And yes they were built alot more rugged than a D17 which is a very dependable tractor in it's own right.
