Just finished doing some work on the 2255. Had steering box off and most lines loose. Any ideas on how to bleed (prime) the hydraulic system? I've bled the valve just above the filter and the resovoir is full. Again the system was basically dry. It worked fine before working on it, but this has been an eight month process.  Also my light is staying on that shows no oil pressure in the rear end (90 weight oil). Any ideas on bleeding that system? Thanks in advance.
