 Transmission Fan Blades

I was crawling under my 2210 last week with a lube gun and happened to look up at the Hydrostatic Transmission. There is a plastic (Nylon?) fan on the front end for cooling I suppose. Anyhow, I'm missing 2 blades. THey seem to be broken off right near the base.

My dealer is willing to replace under warranty (under two years of ownership), but I'm wonder how blades like that break off. Could a stick get up there?

Secondly, is it an easy replacement? Do you need to take the floor board off to get at it? It doesn't seem like you can do it from below.

Any Advice?

The sub-compacts use the fan to cool the hydro and sticks are the biggest culprit to break off the fins.

Replacement of the fan in one piece is not easy. You have to remove the seat, ROPS, fender, wheels, and finally pull the hydrostatic transmission out the back of the tractor in order to remove the driveshaft from the transmission to permit sliding on a new fan. Definately a lot of work to replace a fan that costs less than $8 and is likely to break again.

My god they built the tractor around a $8 fan.

That's an incredible amount of work!! I can't believe they designed it that way. There should be a quick bolt to remove to get at the fan!

I'm sure not everyone goes through this laborious process or the cost. What do others do? Do you just run with the missing blades? Does it affect the tranny?

It would seem to me that an enterprising person could design a split fan assembly that would open like a clamshell and go on the drive shaft. It could be secured with something like hose clamps or embedded screws.

And yes, I ran my BX for several months with a missing fan blade.

The fan bolts onto a flange attached to the driveshaft. There are four bolts that make the connection. I have learned of a replacement approach that involves cutting the fan into two halves. Each half will be held by two bolts. To restore some of the structural integrity it seems to make sense to use some glue when installing the second half.

The fan on my 2210 tore up this winter while I was using my LX4 rotary cutter for the first time. I bought a new fan to replace the one I tore up and need to get it installed on the tractor this week now that the outside temperatures have started climbing. I plan to use the above described approach. No time to go the other route that involves tearing off the rear of the tractor.

Are the replacement fans stonger than the originals? I'd hate to think of doing this again every few years. This operation has to take several hours to complete I'd guess.

Surely those who run their machines professionally in a harsher environment than my backyard, must have encountered this problem. The split fan concept (above) seems plausible. Anyone tried it?

I just looked at the 2210 online parts catalog: (http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.HomePageServlet_Alt) .

It appears the fan is attached to the drive shaft from the engine. Is it possible to drop that drive shaft and get at it??

Probably still too much work taking everything off around the rear of the engine to remove the driveshaft at that point of connection.

I have since learned of someone who disassembled the rear universal joint on a 2210 to provide the clearance necessary to pull the splined end of the driveshaft out of the transmission and replace the fan.

Supposedly took just a half hour to do using this approach.
