mdtoro 2 #1 Posted July 27, 2024 Looks like I have some oil leaking from the seal behind the clutch. Do I need to pull the motor to get at this seal? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,137 #2 Posted July 28, 2024 Wonder if the question is answered in the service manual? A model number will sort these more and the serial number identifies the model year. 3 pages of search results for the 520xi https://www.wheelhorseforum.com/search/?&q=520xi&type=downloads_file&page=2&search_and_or=or&sortby=relevancy 1 Share this post Link to post Share on other sites
Fordiesel69 263 #3 Posted August 6, 2024 When looking at mine, it appears you can remove the clutch and use the two screw method. Also make sure the front sump is not leaking. 1 Share this post Link to post Share on other sites
mdtoro 2 #4 Posted September 7, 2024 Seems to be getting worst as I mow. Trying to limp through the fall and make it a winter project. I'm a little suspicious of the crankcase breather reed. Share this post Link to post Share on other sites

RED-Z06 2,277 #7 Posted September 8, 2024 If its the kohler command they were known to blow out front seals, usually completely out. Pull the clutch and its accessible 1 Share this post Link to post Share on other sites
mdtoro 2 #8 Posted October 5, 2024 The front seal replacement was pretty easy and it did stop my oil leak. Took off the front bumper and pulled the battery. To pull the clutch I tried using a socket wrench and a pipe wrench to hold the clutch but could not get enough leverage. Using my 1/2 inch Ryobi impact driver made short work of the clutch removal. Two screws on the seal and it easily popped out with a yank from a couple of pliers. Used a section of pipe to tap in the new seal. I did note that you need to pay attention on how the clutch is mounted. Now that I did it once it would probably take about 45 minutes to do the same again.
