gwest_ca-(File Mod) 10,479 #2 Posted November 30, 2017 4" OD for the 8-speed transmission Original 7451 replacement is Napa 7-05218 For a replacement with a better ball bearing Napa 7-05485. It is also available from Toro as 99-5678 but Toro does not list it as a replacement for the 7451. Garry 1 1 1 Share this post Link to post Share on other sites

BOB ELLISON 2,976 #5 Posted December 1, 2017 (edited) This is the info I have for my 74 c160 hydro. If yours is a 8 speed I think it different. Yes the 8 speed is a 7451 so it's a different number. I just looked it up. If you have a 8 speed follow @gwest_ca post. 7434 replacement Stens 280-586 HD - this may have a real ball bearing Stens 280-081 Std Napa, 7-05434 Rotary 722 112426 Pulley-Idler Edited December 1, 2017 by BOB ELLISON Share this post Link to post Share on other sites
