case 580ck w 33 backhoe

scottie49 · Aug 21, 2015

I have a problem with my backhoe, the bucket curl valve will not fully bottom to uncurl bucket with any speed. Just started yesterday, I checked linkage and found no problem. Valve will not depress to gain full flow. I pulled cap from bottom of valve and checked the spring, no problem there. Any ideas please?

you may have a chunk of packing from a cylinder that is in a port and stops the spool movement would be my first guess,, you "might" be able to see it/get to it by pulling the two bucket hoses at the spool, then remove the two fittings that screw into the spool,, might luck out and its right there as it would not go through the port

Thanks for the information, I will give it a try to keep from having to remove the whole valve block
