transmission fan shot.

[David s Von Gieserbrechta]

Ok so today I trashed the transmission fan on my BX2350. where do I start on the replacement? what I mean is what is it that I have to do to get the old one off and then put the new one on? And before anyone pipes up about a skid plate, yes I have one from bro Teck but somehow a stick found it's way through and tore nine of the ten blades off, the tenth one is just hanging on by a thread.

Now I can make a new one out of Stainless Steel but I still have to get the old one off so that I can see how it's made. Any suggestions?

Just go part-way into the replacement procedure .
Are you going to make a two-piece metal replacement ?

Kubota left a couple of steps out of the procedure that are imprortant. About half way down, it should say "insert gun barrel into mouth 2 to 3 inches" then it sould say "pull trigger".

Man, that work shop procedure didn't look too bad being 4 pages with mostly pictures, until you realize each step is about an hour's work. Seems to me Kubota should have anticipated the need for some owners to remove and replace the drive shaft fan and could have made that bell housing or bulge just under the seat removable with some screws/bolts. Pretty sure that bulge is to accommodate the fan. That would make removal much easier, but you'd still need to gain room to separate the drive shaft from the HST. :confused2:

I can understand that, with Kubota's method it's a wonder that I don't have to remove the rudder on my Cessna to replace the fan on my Kubota, as a matter of fact it would be easier to remove the rudder on my Cessna than it is to replace ANYTHING on a kubota. I mean even the oil filter is a pig what with all of the hydraulic lines running around it.

I think that I will just cut the shaft, remove whats needed and weld in a telescoping splined shaft from the mower as I have a spare one of those. That way if I wreck another fan it's just a matter of loosening the bolts and sliding the shaft together, replacing the fan and extending the shaft, tighten the bolts and it's done. I think that makes more sense than pulling the engine or dismantling three quarters of the tractor to replace a $20.00 Cheap plastic fan. Makes sense to me but then again I don't work for Kubota.

Great reply!

Thanks for the PDF, at least it gives me a place to start. Personally I think that Kubota should cut me a check for all of the Re engineering that I have done on this Bx, from the wheel weights to the crappy support stand on the loader,either that or paint them yellow and change the decals to TONKA !.

As for the two piece fan, I don't think so, two piece would be more work and the stainless fan will just grind sticks, stray cats and any Amway salesmen that happen to get past the skid plate.

Hey that was my idea:laughing:
If I had one of those that is what I would do.:thumbsup:

I sheared the blades off mine a year ago the same way on myBX2200. The dust boots on the CV joints were worn out also, so I replaced them and new ball bearings and some grease at the same time.

I did not have a manual and total job took about 4 hours. I accessed from underneath to remove bolts of the driveshaft, then took off the pedal & floorpan and removed the shaft from the top.

If I remember correctly the floorpan was kind of tight to remove without taking off the seat, but I got it off with no damage. The shaft was a tight fit also, but I got it out a lot easier than removing the engine!

This would be a good time to replace the fuel filter under the tractor if it needs it and if your fan belt is showing wear, replace it now as you have to unbolt the driveshaft to change it.

Good Luck

Sorry, I didn't mean to rain on your parade, but all it takes is just one look at this crappy design to see how it SHOULD have been done but wasn't. It seems to me that KTC goes out of it's way to make on site repairs almost impossible for the average owner, thereby supporting their dealers. Yesterday I called my dealer and got a quote of $675.00 to replace a $20. fan plus another $100. for pickup and delivery. This I can assure you is NOT going to happen, not in this lifetime anyway.

Putting a solid one piece shaft between two essentially immovable objects makes no sense whatsoever, especially when a part on that shaft (in this case the fan) is basically designed to fail. It makes no sense unless the intention is to make things so complicated that the average owner is forced to take it to the dealer.

Case in point, just try to replace the O rings on the hydraulic valve which on my tractor have all blown one after another due to improperly machined fittings (which KTC refuses to replace) without stripping down half of the tractor, Yuh can't do it. Yuh can't do it unless you do what I did and that was to use a cut off wheel on a angle grinder and cut a hole in the base of the battery case which serves essentially no purpose except to make it all but impossible to get at the fittings without stripping down half of the tractor.
Now should another O ring blow all I do is remove the screen and battery, use a 1" socket, unscrew the fitting, replace the O ring, dog down the fitting, replace the battery and screen and I'm good to go and it all took less than ten minutes. Sadly doing it this way the dealer doesn't get his pot of gold. (my tears flow in his direction)

The wife has started to refer to the tractor as the BS 2350 and I think that she might well have a valid point. Green is starting to look better all of the time.
