I blew a hydraulic hose that went to lift the arms of the 430 FEL on my 4400 HST and decided after a dozen years, I might as well replace all four hoses. While removing the four hoses with the bucket stuck in a big dirt pile and in the rain, I failed to notice which hose connected to the upper fittings on the loader arm. Would somebody please check me on the sequence of hoses both at the quick couplers at the bottom (which are in a straight line unlike what is shown in the manual) as well as the fittings at the other end of the hoses on the loader arm:

Starting from the outside away from the tractor for the quick couplers: black, green, yellow and red

Starting from the top of the hose connectors on the loader arm and going down: black, green, red, yellow
---------------------------------------
Next issue -- ONLY on the green quick connector was located what appeared to be a one inch long brass spacer between the male quick connector and the hose -- inside that "spacer" was located a loose brass disk with a hole in it and flat on one side with a center slot on the other.

IS there only a "one inch spacer" on the green hydraulic connector and none on the other hydraulic connectors?????

Which direction does the brass disc face when the "one inch spacer" is connected to the hydraulic coupler?
----------------------------------------
The JD OEM replacement hoses were 4 inches shorter -- hope that is not an issue.

Any help with the above will be greatly appreciated -- I desperately need to get the tractor back in operation (the dealership is often too busy to help with such questions)

Quick couplers left to right: Black, Green, Yellow, Red
Loader hard lines, top to bottom: Yellow, Red, Green, Black.

The green hose is for the lift cylinder head end, so it is to raise the loader. I am guessing an orifice to slow the raising? Not sure of the direction, you have a 50/50 chance of getting it right the first try. ;)

Thank you, thank you, thank you!!!!! You are a lifesaver!!!

BTW -- The service manager indicated that the orifice disc is placed smooth side up to slow the speed of raising the bucket.

Did I mention THANKS!!!!
