Kubota B21 Hydraulic Hose Replacement

[goeduck]

Those hard lines are not easy to straighten. Unless you have good equipment for bending tubing you are almost certain to create weak spots (as you say fatigue places) in the metal which will eventually cause problems. It may not be pretty but leaving them alone is the best option. To my pocket book they are too expensive to wholesale replace all of them. Maybe sand off the rust would be good.

Your paint is not so good either, etc. If you decide to spend money for restoration and appearance, do the new hard lines when you do the paint job.

Okay, thanks I will leave them. I have had this tractor under cover since I bought it two years ago but some of the paint, particularly on the loader, is quite faded. Some of it is nearly new looking. I am guessing it was kept in a shed with the loader facing out. I think at some point I will go over the tractor with rubbing compound to get some oxidation off of the paint and call her good.

I replaced the six backhoe hoses that are run through the boom this summer. I brought them to two different places to have them made up; one was a hydraulic supply house and the other a Kubota dealer who made up hoses.
Both place the fittings were almost as expensive as the factory hoses complete. None of the auto parts stores close to me make hoses.
I was told by the Parker Hydraulics guy that the Kubota hose is a plastic hose not rubber and is more expensive than the normal rubber hose.
Total Kubota cost with tax was $293.74

In the event it helps anyone...

Here's what the pricing looks like from Messick's for the individual hoses. $237.39

Added in Edit:
The PDF file didn't look so good, so added a pictures of cart.

I replaced all the loader hoses on a B20 years ago. Ordered from surpluscenter.com. Better and higher capacity than OEM. Tough guard Parker mil spec. About half$$$.
Have used them for several projects.

Careful not to over tighten JIC fittings.

Never seen that website... I like it! Not sure if hoses with a "higher capacity" are appropriate in a closed hydraulic tractor system??

Similar pricing at Golden Eagle. I redid 8 of my FEL hoses. I need to do the rest and the backhoe.

My B21 BH Sprung a leak today somewhere in the BH boom - I have yet to determine which hose is leaking (waiting for my neighbor to come by to look inside while I cycle the dipper and bucket to ID the leaking one).

But just looking online at Messicks and Eagle, Kubota wants $900. now for 6 hoses! a 300% increase since 2018!

Probably will replace them all now once and done - vs doing one every year or so.

Also, how did you guys replace the boom cylinder hoses - as the connections are up inside the boom?

Do you pull the cylinder or disconnect the upper end and retract it with the boom boom and dipper on the ground?

Thanks in advance!

Well nothing is leaking up in the boom - its at the swivel point - covered in the nylon wrap - need to cut that off and see which hose is bad - but I just went ahead and ordered all the hoses now - once and done.
