I had another look at this earlier. Here is the valve body with the two valves
My swing motor line doesnt appear to be tee'd into body it goes into the side of the main chest
I opened the blank plug nearest the cooler lines and could see a 13mm nut and thread below. This has a little locking tap on the back of it so would i be right in saying it should be fine?
I then opened the front plug to see a spring assembly which i presume hold the backpressure in the system
Is there anyway of telling is the back pressure to spec? The reason im checking through these bits is every now again if working on a batter when you leave go the swing the house may slow to nearly a stop and then turn away slowly for another few degrees on its own. It might only happen once a week but im curious to get to the bottom of it.
Thanks
James
