Well, first major problem with my 2002 BX2200... My rear right hand axle seal is leaking. Got ~2,400 hours on the machine.

It's a slow leak, but I got all the parts and it works out perfectly because it is due for a full service (less the lash adjustment).

When buying the seal, I noticed that the seal is also used on some of the RTV vehicles, which apparently is prone to leaking too.

I'm surprised I got this long out of the seals, especially when reading that most RTV owners experience the problem around the ~800 hour mark on their vehicles.

Also pleased with my local Kubota dealer -- ALL parts were in stock, with plenty on hand.

Going to replace the axle shaft bearings and seals on both sides and drain and refill the transhydraulic oil, along with a new filter.

Just thought I'd share this. These older machines are so well built and are a pleasure to work on! :D

Still considering adding another (older/low hours) bigger Kubota to my fleet, but this one still suites my needs and has never ever let me down even in the most demanding tasks. Extremely pleased with my little Kubota. Still gets compliments to this day!

I replaced the seals and bearings yesterday, as well as doing full service (except the lash adjustment (not needed yet due to hours)).

Having a hydraulic press and adapters made effortless work of this task.

Took pretty much the entire tractor apart. Full days worth of work from start to finish.

My tractor no longer leaks and is a happy clean tractor once again. :cool:

As per my service yesterday, I did the following:
  • Fuel Filters
  • Fan Belt
  • Coolant Flush and expansion tank clean out
    • Thoroughly cleaned radiator from chaff and dirt
  • Transhydraulic Fluid
    • Replaced Hydraulic Filter
    • Cleaned Screen
  • Front Axel
    • Pivot Adjustment
    • Drained and refilled axle
  • Replaced both left and right rear axle seals and bearings
  • Oil change with filter
  • Air Filter
  • Removed all wheels and pressure washed them and the tractor
  • Greased all zerks
I know you all want to see pictures...
