fired up buggy. 

imediatly noticed power steering pump not happy, dead headed.


ran output hose direct to tank to ignore that / think about it.


fought with cooling system on and off for 2 hours, cant get to bleed, bah!

fuel system good
exhaust good
wiring good
transmission still good after re assembly


50$ grab bag orbital is wrong kind.  determined its closed center with 5th port load sense.  not open center with 5th port power beyond.

new open center 4 port orbital installed with rear steer spool valve in series.  works mint.  3.5 turns lock to lock (lots of steering angle!) and rear stear works great. 

thermostat had no bleed hole and would not open to allow engine to pass coolant.  gutted t stat and all good.  if i get a new one i might put a 3/8" hole in it and keep the stat functional. 


rips around good, gearing with 3.73 seems like it would be crawlable so 5.38s should be nice.   


on to hit list for a shake down run.  a little bit a fabrication left and wire/plumbing clean up.

lots of work left, but glad its moving, charging, cooling, holding oil. 


brakes and hubs / gears and such lol
