Troubleshooting


If a hydraulic implement is not moving (or barely moving) check the quick connects on the hydraulic lines. If they are not connected properly, the fluid cannot flow in that circuit to operate the implement.

Also see the Pressure page for information regarding that.

The BX24, BX23 and BX22 use the following Snap-Tite equivalent components:

Snap-Tite coupler = 72C4-4F NPT
Snap-Tite nipple = 72N4-4F NPT

Here is the explanation of the code:
72 = the ISO standard
C or N = Coupler or Nipple
4 = ¼ in size
4F = ¼ in Female hose connect
NPT = National Pipe Tapered thread. You must apply thread sealant to male part only during installation.

lmmaninky Hydraulics leak at control valve for front loader 1 Jun 26 2013, 3:06 AM EDT by apmillard
Thread started: May 28 2013, 11:31 AM EDT  Watch
Has anyone had trouble with oil leaks on the bx24 front loader other than me???? I've replaced no less than 6 o rings in less than 300 hrs. and a little over 4 years...This tractor has not been abused with myself being the only operator on medium to light duty jobs....The dealer I bought it from has been little or no help. The O rings are genuine KABOTA parts...This is the control valve that is located under the battery...Also, I saw where someone had trouble with the cooling fan for the hydraulic fluid...I rolled over a very small twig when my tractor was only a couple weeks and broke every blade...Nobody told me that there was a guard available for 25 dollars...Should have been included in price of the tractor...Cut new blade in half...Use some wire and wire ties plus the 2 drive shaft bolts ...Time is minutes compared to the way the repair manual tells you to do it .....Mine has lasted 3 years......

no1hog Slow Hydraulics on BX-22 0 Oct 27 2011, 5:44 PM EDT by no1hog

Help needed! I have a BX-22 with about 500 hours and have had all the service done as suggested by Kubota at the dealership. Expensive! I have had a problem of hydraulic hoses failing and have had to replace 5 or 6 of them in the last year. The last hose that failed was on the backhoe and I didn't see it right away and lost lots of fluid. I replaced the hose and fluid, and now have a situation where the loader and backhoe barely move. I have changed the fluid, the filter and the screen, with no improvement. Do you think my hydraulic pump is damaged? The tractor runs great and the transmission runs as good as ever. Only the implements are slow moving. I also have sporatic power steering drop outs, but not all the time. Could it me the priority valve? I need suggestions. I have ordered a pressure test kit, but it hasn't arrived yet.

woodchopper43 3pt. hitch not working 0 Jan 15 2010, 3:45 PM EST by woodchopper43
Thread started: Jan 15 2010, 3:45 PM EST  Watch
today I lowered my 3pt. hitch which had my log splitter attached. Lowered it to lowest point possible approx. 6 inches from ground. Was then unable to raise hitch at all. Position and draft levers move back and forth with no movement whatsoever from the 3pt. hitch. Hitch continues to maintain approx. 6 inches from ground. hydralic fluid level is ok.. Seems like hitch has become detached from housing(?) tractor is: 1987 kubota L4150
