4610 hydraulic couplers

The hydraulic couplers on my 4610 started
leaking badly. Good steady stream when in
use. It looks like there's some kind of
plastic washer in the coupler that's coming
apart. Is it just a matter of fishing it
out with a hook and replacing?
 

4610 parts catalog shows regular or deluxe coupler. I think female coupler will have o-ring & backup washer. Yes you're correct they can be removed with a pick & installed utilizing index finger.
 

O-ring for deluxe remotes is NH # 9861431
$8.00 each

Take a pick and remove the old one then work a new o-ring back in the grove

Ive done this to my 6610 and neighbors 5030, not a big deal to replace
If the rubber boot is bad replace it as well to keep trash from getting in and damaging the new o-ring

The rubber boot is NH # E1NND954AB, cost around $18.00
One boot covers two couplers
