I said replace cylinder and piston and Ultradog said no need to if nor scarred/gouged up but there is no reason for it to be. I tend to now agree with Dog. You can do the leak test first. See if cylinder leaks down -that will tell you the piston is leaking -probably worn out rubber O-Ring and leather wiper. I still recommend getting a new piston, O-Ring, and leather wiper. I don't know if CNH has a 3" nylon wiper for the NCA piston. I used the nylon wiper in my 8N 10 years ago. I've used the leather washer on other guy's tractors since. How do you it tell which is better? How does one gage the difference??? I also suggest you get the parts from JUST8NS and forget about CNH. The lift cover gasket and kit - p/n NCA-500-K, $10. DC has a major Hydraulic Pump Overhaul Kit, $497.00 and a repair Kit/Piston Type for 453.95, p/n CCPN-600-AB. Pump is totally different than the N-Series so will need a 55-59 MPC. The essential manuals will guide you thru the steps so advise to first get a FO-20 manual.
