A general overview of a 8 piston rotary cam hydraulic pump. Cleaning and deburring the damage from piston locking up, causing air to cavitate,stopping it from working.
This pump intimidates me as well as the JD "fuel injection pump". And my 1984 JD 500C BHL probably could use rebuilding on both of them. You're right, there aren't too many videos on them and there are a shit ton of little parts in there. Thank you for posting this video!! I subbed...
I have the same problem on the 4755 john Deere tractor broke the couplers.. to the engine. It had a bad bearing so I need to replace almost every in there
