4430 Clutch Operating Piston

[johnyquest69]

I posted earlier about SCV’s getting slow after an hour or so with PTO running. After some of the advice I received here and there, I split it and found oring broke on pto operating piston. Looks like I see a little wear on piston itself but JD wants $780 for this baby. How many of these have any of you had to replace from wear? TIA!

I have never had to replace the piston,,but I have replaced a lot of the o-rings..
