Pullstart 63,083 #2 Posted October 20, 2022 No you do not. This is assuming you don’t need bearings too. Generally when they wear excessive, they take out the seals. 2 1 Share this post Link to post Share on other sites

But first you should check the bearing for wear by pushing on the axle. There should be no up/down or front/back movement. In/out is OK If the bearing is bad, you must split the case and replace the bearing or the new seal will also leak. 3 1 Share this post Link to post Share on other sites

gwest_ca-(File Mod) 11,090 #5 Posted October 20, 2022 Here is an illustrated parts list. Then go to the top of the transmission forum and some charts are posted to lists of today's seal and bearing numbers available locally. We also have a vendor that can supply. 1 1 Share this post Link to post Share on other sites

ebinmaine 68,263 #11 Posted October 24, 2022 In the 3rd chart above see where I've circled. Lowell at Wheelhorse Parts and More will have that and they're available at a GOOD local parts store. Share this post Link to post Share on other sites
