I have a L2900DT-GST (4wd) and while plowing snow a couple of weeks ago I noticed hydraulic fluid dripping from the bottom of engine, front drive shaft cover and clutch housing drain port (split pin?). The only symptoms were the power steering seemed sloppy. I parked the tractor and put a pan under it to catch the hydraulic fluid. At least 3 gal of fluid was in the pan before stopped dripping.
I've added more fluid but it keeps just dripping out.
I have also tried to locate the leak but can't find its source. I've looked at the power steering lines and they are not the source.
As I have already said, the hydro fluid is leaking from the split pin, the engine oil pan and the front drive shaft cover.
Where else should I be looking? Is it possible for the hydraulic fluid to leak from inside the clutch housing?
If anyone has an idea what is wrong and knows the fix please post details.
Any help would be greatly appreciated.
Thanks

Not sure what the split pin is, but I have the same exact tractor and hydraulic fluid is coming from the right rear axle area. Haven't isolated the location either. Maybe a seal at the end of the housing or some of the large bolts that screw into the housing from the bottom. I see fluid on the inside of the rim. Probably need to pressure wash it and put some something down to see if I have more that one leak and can pinpoint it.
Thanks Murf, any tips on that task? Initial thought is I'll have to pull something to remove some type of lock before I can pull that axle to R&R the seal.
It's been a long time but from memory, the axle has to be disconnected inside the diff. case to free it to come out. I can't remember though on those smaller units if it can be done through an access port or not.
Hopefully Art or Kevin will pop their head in and give us a Orange dealers point of view on it.
Thanks MURF for the info.
This sounds like a dealer repair. I've done some looking thru the Parts/Assembly catalog and it looks like the seals are pretty deep in the case.
In order to get the tractor as bare as possible I plan on removeing the front end loader and mounting bracket and removing the mounting plate for the belly mower myself.
Any rough ideas/estimates of what this repair should cost?

re: L2900DT Hydraulic leak
I believe that your problem is with an oring on the prop shaft that has backed-up
There is a service bulletin to adress this issue( PSB-1998-012) and a kit (TA040-98001) to fix it.
Basically you remove the bolt joining the pro shaft cover, remove the shaft by sliding the cover front then rear and removing the pins from the shaft couplers and the kit consist of an instruction sheet, 2 orings and a spacer that slide on the shaft and stop the oring from backing up.
On your tractor this spacer was factory install starting at serial # 61866 so if your tractor is below that it's almost sure that it is your issue.
Wow, that's some good info. Is there anything you can share with me on the rear axle seal R&R? I ordered a cd with a parts breakdown, but as I suspected it has so many different models that none are in very much detail.
Hey MCHMG1 go to Messicks web site I think you can request the parts catalog from them for free. You'll need to provide the modle of your tractor and they will send you the proper catalog that will have detailed cut sheets. If you spend some time looking closely at the cut sheets you will get an idea of how to dissassemble and fix.
