John Deere 790 w/419 Loader, Cub Cadet 1250
Replaced the 4 rusted solid Pioneer quick connectors on the 419 loader, connected to my 790 and in the process forgot were this little brass washer goes. I belive but not sure the part no. E40500 in the picture part number 15
It goes to one of the 4 hose connectors just like the picture found on the net.
I installed it inline 2, however the bucket now drops too quickly and the curl action is slow. Very new at this and learning about the hydraulics on this tractor.
The scematic cut and pasted below from internet and is similar to 419 Loader.

Thank you in advance,

Move it to another line to find the one that works best for you. Let us know how it works out for you, hoping it is better.
The orifice is to limit the flow of oil.

My guess would be rod end of the curl cylinders to reduce the “floppy bucket” problem.

Also have to figure in that the curl bucket down might be fast because of the regenerative circuit. The OP may not be familiar with that feature (if it is even on the JD 790)

Good link for explanation

Update; I moved the orifice from line (2 bucket) to line (4 boom) as was mentioned in the comments above and it would seem to be working like before.
The bucket speed seems to be even in speed both directions and the up and down of the boom seems to be like it was.
Thank you all for the feedback and support. great forum!
