Loader dump vs recoil

[BlackRaptor]

This might be a dumb question but i dont remember this from my 2520.
when i dump it's about half as fast as the bucket recoil. or that normal? the up down and recoil are all about the same speed but dump is a lot slower.
If this isnt right i wanted to talk to the dealer about if something is wrong.
Thanks.

What do you mean by "recoil"
Is the dumping speed with a full or empty bucket? Are pushing the lever all the way into "fast dump" ? If the bucket is empty, "fast dump" might be slower since it relies on gravity and the weight of the load to help increase the dump speed.

Does it have electronic controls for the loader. If it does all the different speeds can be adjusted and fine tuned to your needs.

If you mean the speed In which the bucket dumps and turns up, then I would say I noticed something similar on my JD.

I had a repair guy over for another issue and asked him about it. He jumped in the cab and showed me that you have to push the lever alllll the way for a fast dump motion.

I have pushed it all the way maybe i need to play a little more with it. hmmmmm
Seems odd. Tomorrow i'll time full dump to full recoil maybe someone else can compare seems slower than the 2520 dumped.
Maybe i need to just chill and enjoy the radio and AC and not be in a hurry haha.

Unless there are flow control devices in the system, the curl back will be a bit faster than the dump (without the regen). The reason is that on the curl back, the volume of the cylinder rod as it retracts does not need to be filled with oil. Assuming that the curl/dump cylinder is 1.5" diameter, and the rod is 1" diameter, and my math is correct, then the rod occupies 44% of the total volume of the cylinder in the end that the rod is in. It would then take 44% more time to dump the cylinder than it takes to curl the cylinder. It also means that the cylinders can exert 44% more force in the dump mode than in the curl mode.

I think the cylinders are probabaly metric dimemsions, but close to those used in the calculations. At least, they are on the cylinders on my 210 loader.
