I ran across a lube and maintenance book today and will look again tomorrow for the parts book and a 315 engine book as I am quite sure I have these books. I don't think there is a grader service manual. I looked for a 212 grader service manual and found out they didn't make one. turns out you need a #12 grader service manual for the 3U and I think I have that one too. I will dig them out and post pics and prices soon. Charlie
I would appreciate it. I'm looking for anything I can find on this machine. I did get a parts book with the 12 I bought but being a decade older I have no clue how much is the same. I know right away I will put the hydro boost steering on this one from the 12 hopefully it's an easy bolt on. and If the control box is the same I need parts for the blade rotate ASAP. The blade rotate control you push like you are giving birth and it tries to kick out and grinds. Played enough with old stuff to know it's fool hardy to attempt repairs without manuals. Pull out bolt A and have ball Ball b followed by spring C ricochet of your forehead then into the great beyond. lol...
I have a manual service information cluch and transmission 3u up with 31 pages,1 operator's instructions 3u1 up 97 pages and have 1 manual servicemen's 41/2 bore d315 and 112 grader with 299 pages.
I just have Parts Catalog for Caterpillar No. 12 Motor Grader 8T1 - 8T14781
and
Parts Catalog for Caterpillar No. 12 Motor Grader Direct Electric Starting 8OC1 - up
Sorry not the ones you need
