itsjustourmail@gmail.com 0 #1 Posted September 2, 2023 Can anyone help me with the correct part number for 312H (31-12KE01) idler arm and corresponding bushing. I can't seem to find the part on any part diagram. I could just weld it up and grind it back down, but thought maybe I could find a good used one. Thanks for any help!

peter lena 8,780 #3 Posted September 2, 2023 @itsjustourmail@gmail.com take advantage of @daveoman1966 opportunities notice your / lever arm , bushing arm is lubrication . dry , AEROSOL PENETRATING OIL , BOTH SIDES , those idler pulleys are known to fail early , is it rough in motion? every relation motion point can / should move easily . how low is your mower deck setting? higher , lets it vent and discharge better , pete Share this post Link to post Share on other sites

ri702bill 8,546 #8 Posted September 3, 2023 (edited) I, for one, like to modify the bushings since you are going to redo the whole thing. I chuck them in the lathe and undercut a 1/8 wide groove about .010 deep in the middle of the shaft bore to make a recess to hold chassis grease - since these have no good access for relubrication. Pack them at assembly, One and done.......... Edited September 3, 2023 by ri702bill 1 Share this post Link to post Share on other sites
5151 11 #9 Posted September 4, 2023 Are you guys running a stepped bushing at both ends of the shaft? Mine has wave washer, flat washer, and step bushing at pulley side and just an e clip at other. As per the parts viewer I looked at. Share this post Link to post Share on other sites
