LT160 Transaxle Pulley Problem
I haven't been here in a while but now have a problem that I need help with. I have a 2005 LT160 SN MOL160D530506 with 275 hours on it. Yesterday after mowing and cleaning up, I went to drive the tractor back into the garage and heard a rattle/grinding sound. I stopped and after further checking it appears that the pulley on top of the transaxle is loose and I can easily move it back and forth with my hand. I have no idea where to start with repairing this and I'm wondering if it's even something I could repair myself or should I just take it back to the dealer? Once this happened, I was afraid to drive it for fear of making things worse so I just pushed it into the garage. Can any of you more knowledgeable repair guys advise me on what the problem might be and what kind of expertise or special tools one would need to repair it? I do my own maintenance but have never had to fix something like this. Thanks in advance!
