I'll check it tomorrow and post here for posterity. Since Frampton was apparently not correct when he told me my rig was the last of the initial 13 rigs to get the bypass installed prior to it becoming standard ops for continuing design, there might also be another rig w/this issue waiting to rear its ugly head. It was an odd failure- all of a sudden the hydraulic cooler would see an increase in pressure sufficient to blow it up. My rig went 1000 miles w/out the issue, and they moved one bare chassis around the lot and it blew the cooler. Random. IIWYI'd make this happen before putting a buncha miles on. Frampton wanted to have my rig towed to the nearest service point to install the bypass; it was only maybe 6 miles, so I talked him down and drove surface streets so if it blew I could pull over & get towed from there. Fortunately, no blow.
While you are in the neighborhood, you should check your PTO to see that the red mid-case between the PTO gear housing and the pump ahead of it has a 1/4" oil line going to it. Country Coach was installing the Chelsea PTO w/out the wet-lube in the mid-case and had some spectacular failures (and a recall) for that. Mine came w/the wet lube case that has the spline shaft coupling to drive the hydraulic pump; hope yours does also. Here is a thread
w/some pics & info.
