"Manic-Mechanic" 1,194 #1 Posted October 21, 2022 (edited) I found the worn spline & couplings at the edge, so off to find replacements. "Always love the challenge of finding obsolete parts" Coupling 2-7502 Shaft 2-9539 The factory spline really took a beating at the double sheave end of the 11 spline, as did the shaft as well. Typical issue with this design I found the couplings out of warehouse in Chicago and the spline was machined of 4140 rated 160,000, so it matches the hardness of the couplings no problem Lyle Mack, Greencastle ,PA can make any spline or gear out there or in a drawing Edited October 21, 2022 by "Manic-Mechanic" 1 3 Share this post Link to post Share on other sites
