So far I haven't had to do that. However last year I took everything apart during the winter to give it a good cleaning. I took my time and had the ROPs fenders and floor off in about 2.5 hours and enjoying a beverage or two. slkpk
There is an easier way than having to split the tractor. Basically, remove the floor board to gain access to the fan. Several people have cut the fan in half then put it on the tractor. There are 4 bolts holding it in place. Otherwise, you will need to split the tractor to replace the fan. Reports from those that have done it, suggests that there are no problems nor increased vibration.
This is a reprint of either a post or a private email sent to me from a 2305 owner who replaced his fan. I'm sorry that I've forgotten who it was and when I printed out the text I neglected to copy their name. If the owner of following sees this post, please take credit for it.
"I notice a few people had a cooling fan issue, stick breaking the blades and the nightmare of trying to figure out how to replace it. This exact thing happened to me, and for those of you wondering how to replace it, here is what you need to do. A friend of mine, who is an experienced heavy equipment mechanic helped me out.
First we removed the parts that the arms of mmm attach to (large gold busing). Then we took apart the drive shaft by removing the split ring and knocking out the pin. Then we were able to access the fan, and remove the damaged one with a flexible ratchet and replaced it with the new one. Then we put everything back together. It definitely helped having my friend to help me out, he definitely has the experience and appropriate tools to make the job easier. It took about an hour or so."
I copied the post or email some time ago and put in my JD file in case I ever had the same problem. Maybe, that is of help. Let us know.
Well I got the driveshaft out .Its a tight fit but I was able to get the front pin knocked out.I found that the front u joint is bad but the only way to get it at the local dealer is to buy the whole driveshaft at $500.00.So if anyone may have a place online let me know.My local auto parts is going to try and find a u-joint for me.
