Way to many unknowns here. With your first setup evetything works except loader power down. I thought it would not raise correctly. Why would you swap hoses? I thought this was working and over time stopped working. Did you change or add anything to the system? You have self installed...

Welcome to the family :) Now I am confused which is not an unusual condition. Hydraulic hoses to not typically have an o-ring but the port fittings used with them sometimes do. Exactly where is this leak and what is the model number of the machine. A picture - not to close up please - of the...

I think you better drink that beer yourself - not likely i will be able to cash that ticket. Glad it came out easy and hope the rest of that repair goes as easily. Dan

Common problem with cups used with tapered roller bearings. Run a cold bead around the ID of the sleeve being careful of the housing. The sleeve will contract and if you did a good job with the welder will fall right out. I use that technique on a regular basis to remove bearing cups and I am...

By all means get a caliper i- its an invaluable tool and not expensive but dont buy it jusy to measure that o-ring. SAE O-rings have nominal size like .125x .5 x .75 but the actual measurements will be different. IIRC the cross section of a 1/8 oring os actually .109. Similarly the ID and OD...

Classified by ID and cross section. Cross section is easy to measure - ID not so much. Dan

Parts book shows standard o-rings and Chicago Rawhide seals - nothing special at all. Should be dirt cheap to rebuild. Dan

Perhaps you can find a generic seal that will fit. Chicago Rawhide catalog might be worth a look.

I am not a hydraulics expert but I can speculate. I know the L3901 loader can be raised and lowered at the same time as the 3pt. That is not "normal" behavior in a power beyond valve Shifting the bucket spool will block the three point which is "normal". So what is happening? In general...

How does that work? On most Kubota tractors the loader valve is connected ahead of the 3pt and operates totally independent of it. Edit: Never mind - I spoke with out enough thought. After just a little more thought I realized most of the loader valves continue to supply the 3pt while the...

Never owned or used a box blade but I maintained my 1/4 mile lane with a 3pt blade and the loader for little over a decade. and had no complaints. When that task became tiresome I solved the problem with asphalt and still use the 3pt blade and loader for snow removal. Box blade wouldn't be...

Do the pressure test on the inlet side of the loader valve. That isolates the test result from problems inside the valve. I assume you plumbed your remotes in after the loader and not before? Dan

These are constant displacement pumps so the flow rate from the pump increases and decreases with RPM. If RPM improves lift power and speed I would suspect a leak. The pump will basically make the same pressure regardless of RPM. Increasing RPM increases the flow rate from the pump and helps...

YIKES!!! Dan

I just made those decisions. For HST with loader all of the dealers (except 1) quoted the L2501 with a footnote "add $5k for L3901". That one dealer was about a thousand less on the 3901 and thats the machine I purchased. A big part of my calculus was "free money" from Kubota. Financed over...

Being HST I did not expect it would. I will be interested in hearing how it goes. Dan

This is something you learn with practice. I am 70 years old and I was on my first tractor about 2 - obviously not the operator - that didn't happen until 7-8 :) I have three small Kubotas that I have used for the last 30 years and in that time I have slowly learned the limits of each of...

No nuts on my B7200DT which recently started doing the same thing. The throttle linkage runs in a couple nylon bushings and is held together with cotter pins. Best I can determine wear in those bushings loosens them up allowing the throttle to walk. The DT has a foot throttle so I have not...

I just did that exact job. I had a local company deliver tandem loads of fill dirt ($90 per load) and i spread and graded with the loader. Mine took 7 loads - does not look like you have nearly as large an area. Should be a piece of cake. Dan

That's almost the exact opposite of my story. I went to two dealers near me and got that same treatment. Emailed my configuration to Messicks and got an immediate response. - they had an L3901 and loader in a crate. Next day I drove up to talk to them in person and sign a sales order. Saw a new...
