buddy of mine has a exmark lazer z with the 60 inch ultracut deck, not sure of year or serial number but roughly 02 mabey. bearing in spindle had lots of play in it so took apart and ended up being shaft was bad (wore) where upper bearing is so went to local dealer and they said that exmark doesn't have those shafts anymore, new and different one which also requires him to change his double pully (right bagger side) to fit new shaft. dealer also said they changed the spindle assembly. question one: is this true? can't get the larger shaft anymore, one with the bigger nut (1-1/4 socket)? question two: is the e-clip on the bottom really necessary? with nut on top tight bottom bearing can't go anyware imo and he had to do some switching around because dealer didn't have the double pully in stock so he put new shaft on other side and the bottom cover is hitting the e-clip when he tighten's it up. he thinks it will work fine if the e-clip wasn't there and is just barely hitting now. if he torque's the nut then can't even spin it. any thoughts?
