What crown is selling here is called Hamec ,hope I spelled that right.Looks just like a Tusk to me.Komatsu has had a hand in it with a few controls.Nissan is the power plant but tranny dont look like one in cat or nissan trucks.Near as I can tell it only has a ecm and a controler to lock out hyd.Not worked on one yet.It takes some kind of hand set thats about 5 grand so I dont see us getting tool very fast.
