Justin;
According to the s/n you have given we are looking at a Nissan PE50Y with mast m/n N3F475 and a Cascade SS 55FSSA071. The long model no. would be CWPO2L26SV that was produced Sept 2000 and had a second generation GE pump motor p/n 29110-8G200. Would you go into the program menu of the truck and tell me what you see in Windows 170,180, and 190. Has any work been done on the pump motor? Has the lift mast been damaged? Have you had any service brake issues? Have any control valve switches been serviced? What hyd pres are occurring under unloaded and fully loaded FWR and REV tilt and lift? What is the amount of current for each of the previous actions?
