McCormick 30 Loader Hydraulic Cylinder Help

Have a McCormick No. 30 loader that has a slow leak on one of the cylinders. Also, the leaking cylinder doesn't hold the load. All connections and return lines to the belly pump are as they should be. I have the cylinder apart and am trying to find parts to fix it. I assume I would need to replace the piston cup (450 665 R1) and the 4 packing rings (450 658 R1) I have tried the CaseIH dealer and they cannot reference those part numbers I got from the manual. Does anyone know of where I can get those parts -- maybe new CaseIH numbers, or does anyone have suggestions on how to fix the cylinder. Thanks
 
You may just have to run down to a hydraulic shop and let them put the calipers on everything.
 
I would google "Chesterton" and rummage around their website. They are a leading mfg of replaceable/wearable hydraulic cylinder parts (seals, packings, chevrons, etc). Either that or let a professional handle the job.
 
You may want to try another dealer. I bought the parts to do mine last year from Columbia Tractor in Ghent, NY for about $50 per cylinder. They got me the cups, cone washers and gaskets for the end caps and even had them shipped right to my house.
If it's a newer dealer, they may not be familiar with or want to service the older products.
