#K2561-14250FR BX Series 2-Piece Transmission Fan

Unrated (2 hours)
I would not recommend trying to put this in from under the tractor. I spent 4 grueling hours trying every angle to get the bolts lined up. I never was able to get the threads started and I broke a few cooling fins on the housing during the attempts. I came at it with a fresh head the next day and decided to go in from the top. Removing the seat, ROPs and rear fender assembly took about 30 minutes. Less than 2 minutes later I had the fan installed. Tips for fender removal: use a heat gun to get the plastic knobs off mower deck and 3 point hitch rate adjusters, don't forget to make sure your diff lock pedal is through its slot when putting it back together. I got all the way through reassembly before I realized I didn't, and had to take it all back apart again to get it through.

I installed the fan from the top because I had my plastic fender off to repair it. I decided to completely fiberglass the under area. First, buy or dig for those POS ultra-flat wrenches we all get when we buy items that need to be assembled. I’ve saved them over the years and added longer handles to them. I put the transmission in neutral and lined up the bolt hole to sit between the tranny cooling fins. With the bolt and washers in half of the fan, I slowly and painstakingly, with two fingers, made a complete turn,n grasping a thread or two. Then, with the flat wrench, I turned the bolt as far as it would go without tightening. After turning the shaft to line up the other bolt hole, I slipped the other half of the fan and repeated the process. I was then able to use a regular wrench to tighten both bolts. It was a bad angle, but it worked. The install took me one hour and fifteen minutes.

The fan is well made, but the location is terrible. I fought getting the bolts started for some time before pulling the fan out and drilling out the bolt holes slightly larger. This allowed the bolts to spin, then I was able to get them started using long reach needle nose pliers. Make sure to leave the first one loose enough to allow the fan to pivot a little (but in enough to clear the transmission when turning) otherwise the pliers won’t fit. I was only able to start the bolts on the right side where there’s a little more room for the bolt length. Once started, an open-end wrench brought it home but it’s a slow process given the very limited access.
