Just logged in as a Yesterday's Tractors forum member. I have an older Cat motor grader with a left side front metal tag with the Serial #3U1754. I am asking help in identifying the Cat Model number and the year of Production. Any help would be appreciated...please excuse my ignorance if I have done anything wrong as I have never done any requests before.? DrLHH

Hi & welcome to the forum,
A 3U is a model 112 grader. I can't help you with the exact year, but I would say the very early 50's. I had a 112 grader and it was sn 3U5290 and was a 55 or 56 so yours is older. The 112 was not made in high production numbers vs the 12 grader. The 3U series is very close to the #12 grader of 8T series except for the engine. The 112 has a 4 cyl and the 12 has a 6cyl.

Thank you to DWF, Dick2, and Nik for their kind response. By their information and earlier posts, I have found that my grader #3U1754 is a Model#112 (designated by the 3U in the serial number). I have yet to identify the production year of the #1754, so any forum help will be appreciated. In an earlier post, there was information that indicated a 3U825 serial number was for a 1948 production year of that inquiry. So, it is likely that my grader#1754 will probably be somewhere in the early 1950's. I have looked at numerous online websites, but have been unsuccessful as of this time. Looking for your continued help??? Thanks in advance. DrLHH
