And a 4320 was made after the side console 4020 so probably has the later hydraulics and the check valve fix doesn't apply. The hard to find high pressure leak (or group of leaks) is the official diagnosis.
The SI I quoted only applies to 2510, 3010, 4010, and pre side console 3020 and 4020. I don't have the service bulletins about the later tractors in my collection, only the indices that show there were SB about the topic.
