Is your tractor serial number below 661867?
If yes there is a service bulletin (PSB-1998-012) and a kit (TA040-98001) to solve your problem.
let mw know if you need more info
No, as a matter of fact it's pretty simple and the kit is cheap ($40)
On the shaft, on the tranny side, you have an o-ring/seal that is retained in place by a sleeve.
The issue is that the sleeve can move out of position and when that happen, the o-ring/seal start leaking, sometimes very badly.
The kit consist of 2 o-rings, a shaft spacer and a instruction sheet with drawings
Basically, you remove the 2 bolts holding the 2 pieces of the front shaft cover together, remove the shaft by sliding the cover front then rear and removing the 2 shaft couplers by driving the split pins out.
Once done you put 1 of the o-ring on the rear shaft, slide the shaft spacer over the rear shaft, pushing the new o-ring against the sleeve retaining the leaking o-ring ( that will put it back in the correct position and stop the leak).
You then put the 2nd o-ring of the kit over the rear shaft and re install couplers, pins and cover.
Basically with the new shaft spacer in place, the sleeve is locked in place.
This modification was done at the factory starting at serial # 61867.
I helped another L2900 owner that had the same problem than you about 2 weeks ago and he fixed it following those instruction
so let me get this straight the front drive shaft cover fits into what I would call the clutch housing. If the oil is in the bottom of the clutch housing and runs into the front drive shaft cover why wont it leak around the two sections of the shaft cover? Sorry to be such a pain.
thanks.
thanks.
OK, you lost me here
, your original post say that oil was leaking from the front driveshaft cover?

luc is describing the fix for a known problem on a certain group of tractors with leakage from the transmission around the 4WD output shaft. You need to determine whather your leak originates from the transmission housing, or the front axle center section.
let me see if I can describe this better. The back of the engineis attached to what I would call a clutch housing (thats where the clutch plate is) behind this is the transmission. I think this is what I am seeing the front drive shaft cover goes from the rear of the front axel to the clutch housing. Your prescribed fix seems to discribe this area perfectly I just dont see how the fix keeps the hydrolic fluid out of the front drive shaft cover. Maybe I just dont understand. (thats what my wife tells me all the time
Thanks again!

OK, we're on the same page.
The front drive shaft run from the transmission, through the clutch housing, between the oil pan ( where the cover is) and to the front axle.
Let me try to better describe the problem and the fix
RickB make a very good point, you first have to know if the leak that you see on the driveshaft cover come from the transmission or from the front axle.
Usually, but not always, front axle use gear oil and not hydraulic oil.
Assuming that your leak come from the tranny, the front drive shaft is a 2 pieces shaft, the rear part go from inside the tranny to basically the junction of the clutch housing and oil pan, where you can see the cover.
from there there is a coupler ( hollow tube ) that connect it to the second shaft ( the one under the cover) and this 2nd shaft is then connected with another coupler to the rear of the front axle.
It is this second shaft that need to be removed.
On the shaft coming from the tranny, there is an oil seal located where the shaft go through the tranny case ( like a crankshaft seal).
This seal is kept in place by a sleeve on the shaft.
If the sleeve move forward ( toward the front of the tractor) the oil seal can also move forward and the hydraulic fluid can leak.
To put this seal back in place and stop the leak, you slide a spacer ( hollow tube) over the rear shaft, push it toward the rear of the tractor and by doing so you're pushing the sleeve and oil seal back where they belong.
Once done, this spacer stay on the shaft between the sleeve and coupler and stop the sleeve/oil seal from moving.
Do that make more sense now
yes I think I know what you are getting at. I have to split the tractor anyway to fix the rear main seal. I think I screwed up and put the seal in backwards when I rebuilt the motor.
There is only about 1/4" of slop in the front driveshaft cover is that enouph to make it leak that badly? thanks!!
