Allis Chalmers part drawings

Recommended Posts


I am looking for the idler assembly arm and pulleys for my Allis Chalmers 36 inch tiller. I can make the idler arm if someone can make me a drawing of it with dimensions. And I would also need the sizes of the two pulleys. The pulley part numbers are 2027640 and 2027014. The idler arm assy. part number is 2027633. Thank you.

I wasn't able to tell from your part numbers which tiller and tractor you are working with, but I recently ran through that exercise for my B112. Take a look at these parts to see if they look like what you need:




The parts weren't cheap, but they were available.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
