2210 Plastic Hydrostatic Cooling Fan Replacement

Hydraman · Mar 27, 2006

My 2210 has a shield, but it doesn't appear to be very effective against hidden branches, etc. that one might encounter while bushhogging in tall grass/weeds,etc. that could be hiding stuff just lurking to destroy our fun. I built the additional guard to also protect the tranny filter. I had a freak wreck with the filter while building a drive system for a non JD snowblower last fall and had transmission/hydraulic fluid all over my shop in short order-- hence-- the guard got built to protect both filter and fan.
PS. Please don't ask what happened! /forums/images/graemlins/blush.gif /forums/images/graemlins/blush.gif I just hit the "stupid button" ! Don.

The fan shield on a 2210/2305 is relatively useless.

The fan on my 2210 got destroyed the very first time I used my LX4 rotary cutter. I was traversing the area in which I had just cut brush and a stick got deflected by a tire right smack into the fan.

( Cutting/bolting sounds better than tractor disassembly. How big a job would it be to move the engine instead of the tranny?? )

Haven't looked at moving the engine although I have wondered if removing the driveshaft coupling on the engine end would be relatively easy. I haven't figured out how to get to that end of the shaft. It's pretty well hidden.

Even with the coupling removed there may still not be enough clearance to move the driveshaft forward to pull it out of the transmission.

I think I am not going to mess with the fan. I think a transmission cooler up front at the radiator may be easier.

( I think I am not going to mess with the fan. I think a transmission cooler up front at the radiator may be easier. )

I've wondered about that myself but there are a few things I would want to consider first.

1) Would circulating hydraulic oil through a cooler take away some of the pump capacity and thus slow the operation of the FEL to some degree?

2) Is the fan providing cooling to a specific area of the hydrostatic transmission that is not going to be cooled as well without the fan?

3) Is the radiator size sufficient to handle the hotter air that will pass to it after going through the transmission cooler or is the engine going to run hotter?

Any engineers out there willing to tackle these questions?

I agree on that fan and think a tranny cooler would be better.
Another thought though. How about a 12V electric fan like they use in electronic racks mounted at a different angle, say just above the driveshaft?

Anyone know the best place to tap into the transmission to add a cooler line? Are there any ports that are plugged?

Sawed a new fan in half today and bolted it onto the flange on the drive shaft. Did not use glue. The flange is not perfectly flat so when the fan halves are installed the cut through the fan collar widened. Too wide a V shape gap for the glue idea to work.

Fired up the tractor and ran it for a few minutes and the fan stayed on. Tomorrow will be the real test - three hours of mowing. Got my fingers crossed.

Hello Everyone,

I am fairly new to the forum and proud owner of a 2305. This is kind of funny, this past week I was clearing brush with the loader and of course a stick got caught in the fan and destroyed four of the blades. I was pretty disappointed with what had happened and of course like some of us here who encountered the same problem was completely going insane on how to replace the fan. I thought about taking off the floor plate, fenders, ROPS etc. Started to do that, and that was way too labor intensive. Spoke to the mechanic at the dealer and he suggested droping the shaft at the front of the machine where it connected with the engine. Again, way too complicated.

I am lucky enough to happen to know a fella who is a diesal mechanic for an excavating contractor. He stopped by and here is how we did it, in less than 30 minutes, without cutting anything.

There is a bushing, or bar that holds the mid mount mower that needs to be removed. The transmission shaft is now easily accessible. The mechanic then took the drive shaft apart at the knuckle joint closest to the fan. It seem pretty involved (I am not a mechanic). He removed c-clamps, punched out two bushings and the shaft dropped down and he was able to access the fan bolts and he replced the fan.

I am going have this fellow make me a skid plate of some sort - he is an outstanding welder, definitely a good guy to know.

I am pretty surprised myself on how easy this fan got destroyed. I am going to definitely send a letter to JD.
