Kubota B2100HSD LA301 Hydraulic Loader Color Coding Diagram

[Bob L]

Can anyone help me determine where the hydraulic lines (by color) should go? There are four lines I beleive (White, Yellow, Red & Blue) I had some service work done and the lines need to be reattached.

Probably wont help, but John Deere uses Blue for loader boom lift, Red for loader boom lower, Yellow bucket dump and Black bucket curl. You might get lucky and find the three JD colors match and the last hooks up as the only one left.

Which side of your connections are not marked? You should be able to tell on your valve which couplers are paired. Then trace the hoses and pair them, two for the boom and two for the bucket. Only hook up the two hoses for the boom to a set of paired couplers. 50/50 chance you will pick the right pair and 50/50 chance you will connect in the correct order. Once you have the boom connected correctly , only two possible combinations for the bucket. Even if you are wrong on every try it will only take 5 trys to get it right. If you are lucky you will get it right in two trys (one for the boom and one for the bucket), So 3 extra trys is not bad odds.

Here is one example of written color code for loader valve output. Don't know if there is a standard.

This is a Woods loader and valve on a Kubota.

Here is one example of written color code for loader valve output. Don't know if there is a standard.

My Kubota BX24 has Red to bucket curl (rod end), Blue to bucket dump (base end), yellow to boom up (base end) and white to boom down (rod end of cylinder).
Maybe this is at least a Kubota standard ?
