Front end loader control is stuck.

How does the vinyl guard come off? Tried to remove it and don't know how it fastened.

Page 11 in B7800 loader parts document shows the cover as part 290, looks like bolt 300 is what holds it on.

Thanks for your help. I will give 300 a try.

Do you have the same control valve on the 2710?

Do you have the same control valve on the 2710?

Yes, I had the same problem when mine was under warranty and the dealer came and fixed it in my garage. I wasn't home to watch, I assume they cleaned up the spring and balls and drilled a drain hole.

I have a question about the parts diagram.

Parts are assigned either a number or a letter on the diagrams.

Where do I find reference to the parts that have a LETTER designation?

Lettered parts are only available as part of an assembly, the assembly has a number. So for example on page 9 at the lower right on the page, the assembly #020 includes all the parts labeled A-J. So that means you can't buy part A by itself, you have to buy part #020, which includes the whole kitchen sink.

Thanks, that makes sense. Appreciate the help.

I have to remove the loader on my tractor.

Can I remove the cans on the loader control valve to clean and lubricate while the loader is off and the hydraulic lines are detached?

Do the parts (that I see in the diagram) come off the valve when I remove the cans? If so, how difficult is it to reinstall the inner parts
when the cans go back on?

Anything I should know regarding the removal and installation?

Looks like the cans are 1.25 in. SAE. I assumed Kubota tractors would require Metric tools??

You could make a video of the dissasembly.

Use the PDF to put things back together correctly

JJ-Can the cans be removed and cleaned with the loader off and hoses detached?

You might check for youtube videos that will help you, I found this one. Go to minute 4, the guy is taking the detent balls and springs out of his valve. There's probably better ones if you hunt around.

I also video things like this when I take them apart, then dump the video on my laptop so I can watch it while I do the reassembly.

Yes sir, that is correct.

Be careful, with the HUSCO valve the detent balls are a similar design with 4 balls energised by 1 larger ball with a spring behind it. Where you have to be careful is that when you remove the detent sleeve the balls have a tendency to "spring out". Just be careful you do not lose them. Make sure you lubricate them on reassembly.

It's been too cold to do this repair. If I were to carefully drill weep holes towards the bottom of the sleeves (while still assembled), will that damage anything?
Seems as if that might be easier than removing them??

I can not comment or condone this type of modification, however, I understand the problem. I am not exactly sure the internal configuration but if you take a look at the part number on the nametag I will be able to have a look.

 

[J_J]

You need to inspect the assembly anyway, so look for a weep hole or drill one when you have it dissembled.
