Hi, just joined forum looking for advise. I’m an experienced auto tech I do auto trans and all but as far as mowers never done anything with a hydrostatic trans. Recently purchased a used Troy bilt zero turn and the RH transaxle keeps blowing out the seal on the brake gear shaft. I’ve replaced the seal and topped/purged fluid and it just pushes the seal right out of the casing after a few passes cutting. It’s a oem seal I checked to verify correct size. Wondering if a venting issue is causing this blowout or if another seal is internally bypassing fluid to the wrong port and pressing the seal out. Any help would be appreciated. I’ve attached pictures of the model number and pictures showing the LH seal pushed out compared to the LH. Thanks??
